The Effects Of Interval And Continuous Training Physical Education Essay

The Effects Of Interval And Continuous Training Physical Education Essay In todays society where appearance and health is a major part of modern life, there is a growing awareness of overweight and obesity in the World. For many reasons such as appearance, health many overweight and obese people undertake some form of diet or exercise program to overcome this. In many grocery stores fitness magazine can be found describing new fat diets shed 2 stone in 4 weeks. Weight-loss drinks have become more and more popular as they may aid in weight loss, although most people favour eating actual food than a shake every couple of hours every day. More health clubs have become available all around the country, being easy to access and offering guarantee weight loss. These clubs help people in losing weight, however usually does little to encourage them to stay as they have already received there signing up fee. Success in weight loss programs comes by adherence to exercise, however for a majority of people this is the major issue. These health and fitness clubs strive on selling membership to the general public and most dont encourage people to stay. More exercise and changes in diet are the key factors to weight loss. A change in diet helps weight loss by restricting total caloric as well as fat intake (C. Curioni P.Lourenco, 2005). A change in exercise patterns also aids weight loss by increasing caloric and fat expenditure (L N. Keim et al., 1990 V. Mougios, et al., 2006) Many individuals attempt to lose weight, though never meeting their goals. This is usually due to someone attempting a diet and exercise program for a brief time, lack of changes in their appearance or weight make the participant want to quit (A. Grediagin, et al., 1995) as well as lack of time and interest (Willis Campbell, 1992) have shown to prevent devotion to their weight loss program (Kempen et al. 1995). Body composition is one of the most frequently studied subjects (R. Bryner, et.al 1997). To date, a number of studies have reported the efficacy of high intensity exercise on various physiological parameters related to weight loss (R. Bryner, et al. 1997; J. Jakicic. et al. 2004; V. Mougios et al. 2006). Both men and women begin dieting and exercise programs in an attempt to lose weight however many fail to continue to either exercise or diet usually due to a decrease in results. However, women tend to struggle compared with men when losing weight (Gleim, 1993). Factors include smaller body sizes (Gleim, 1993), less fat free mass (Pollock et al., 1998; Westerterp, 1998), and lower resting metabolic rates (RMR) (Westerterp, 1998) than men. Mens testosterone levels are higher than women, which causes males to have a greater muscle mass and absolute RMR than women (D.W McArdle, et.al 1996). These factors cause females energy expenditures to be less than that of male, so it critical to find an exercise program or diet program for females that will create the necessary results needed for the participants to make sure they continue with that program. The Conventional way of low intensity exercise was considered to be more beneficial way to reduce weight than high intensity exercise because of the greater percentage of fat calories are burned during low intensity exercise (McArdle et al., 1996). Previous research has shown that higher intensity exercise is associated with greater improvements in cardiovascular fitness and greater caloric expenditure, which in turn can assist in improving health as well as weight loss (Perna, et al. 1999, ODonovan, et al. 2005). However it has been shown that high intensity exercise requires a greater percentage of calories (kcal) during and after exercise and is often greater than that of lower intensity exercise (ODonovan, et al. 2005). Substantially following exercise, fat metabolism and RMR has been shown to be elevated for up to 24 hours (Bielinski, Schultz, Jà ©quier, 1985; Treuth, Hunter, Williams, 1996). It is has been highly debated whether if high intensity interval training can be used as a possible treatment intervention in promoting weight loss. In continuous steady state training the speed which the participant exercises at stays the same intensity throughout the duration of the protocol. Whereas the participant completes 10 intermittently exercises at a high intensity alternating with a lower intensity every few moments in the high intensity interval training. Comparing the two training protocols over the same amount of calories expended during a high intensity high intensity interval training program as in a more moderate intensity steady state training program the substrate utilization during these exercises will differ (K. Wallman, et al. 2009). Higher intensity exercise would use primarily use glycogen during exercise whereas a more moderate intensity program would use primarily fat (K. Wallman, et al. 2009). A typical individual would interpret this information as an argument that low steady state intensity exercise is better for burning fat. However, this does not take in to account the fact that fat metabolism is increased after high intensity interval exercise, serving as the bodys fuel source for any post-exercise activity, also to replenish the glycogen stores depleted by the high intensity exercise (K. Wallman, et al. 2009) Its very difficult for many individuals to maintain an extremely high intensity for an extended period of time, thus requiring that near maximal exercise is completed in a high intensity interval training program rather than a continuous steady state program (W. Schmidt et al., 2001) Aims Compare the effects of high intensity interval training versus low intensity continuous steady state training on VO2 max in overweight women. Compare the effects of high intensity interval training versus low intensity continuous steady state training on body composition in overweight women. Lack of studies dealing with high intensity interval training programs as a potential means of weight loss over a short intervention, this specifies that such research is necessary to determine if high intensity interval training is a worthwhile means to reduce total body weight and fat mass over a shorter period. 1.3 Hypotheses / Research Questions The two research hypotheses of this study were null 1) there would be no significant differences between high intensity interval training and low steady state continuous steady state training in V02 max and in body fat percentage; alternative 2) there would be a significant difference between high intensity interval training and low steady state continuous steady state training in VO2 max and body fat percentage. Delimitations Subjects were limited to 18 to 34 year-old female non-smokers, not pregnant, not lactating, and not taking any medications that could inhibit metabolism with a body fat percentage 25% 30%. Subjects, 4 subjects were assigned to either interval training group or continuous steady state training group. Body composition was measured using bioelectrical impedance (BIA) Maximal aerobic capacity was measured using multi stage fitness test (MSFT). The equation was then used to then calculate the VO2max (AD Flouris et.al. 2004 L L ´eger, C Gadoury.1989). V02 max was used to determine the level at which a subject needed to exercise for a given exercise intensity. Limitations A small group, thus limiting the generalizability of the findings. Work environment could not be controlled for. Bioelectrical impedance could only be used for body fat percentage. Multi stage fitness test (MSFT) to assess VO2 max not graded exercise test (GXT). Definition of Terms Aerobic: exercising which requires the use of oxygen Anaerobic: exercising without the presence of oxygen as the work intensity is greater than the rate the body can transport oxygen to be used. Body mass index (BMI): describes relative weight for height. Calculated as weight (kg)/height squared (m2) x 704.5. A BMI of > 25 is considered overweight and a BMI > 30 is considered obese in women. Calorie: energy unit also known as the kilocalorie (kcal). It takes 3500 kcal to be to burn one pound of fat. Continuous training: steady-paced, prolonged exercise (McArdle et al. 1996) Interval training: a form of training that involves high-intensity exercise for a brief period of time with brief periods of rest or low intensity exercise (McArdle et al., 1996) Maximal oxygen uptake (VO2max): is used to measure cardiovascular fitness Obesity: unhealthy high body fat percentages, generally considered >30% for women (McArdle et al., 1996) Overweight: unhealthy high body fat percentages, generally considered 25% to 30% body fat percentage. Steady-state: the point that is reached in continuous exercise where workload and heart rate become constant. 2.0 CHAPTER TWO LITERATURE REVIEW 2.1 Literature Review Obesity is a worldwide issue associated with serious health, social, and economic problems (Brisbon N, et al. 2005). (World Health Organisation 2005) defines overweight and obesity as abnormal or excessive fat accumulation that presents a risk to health. Obesity has been associated with one or more diseases such as diabetes, hypertension, and cardiovascular disease, which have shown to result in serious health issues and even causes of death (C. Stein and C. Colditz 2004). Obesity can be classified into two different sections these being android obesity, where the main proportion of fat mass is situated around the abdomen and waist area, and gynoid obesity, where a large proportion of fat mass is located in the gluteal and femoral areas (A. Kissebah and G. Krakower 1994). Obesity is usually occurs as the result of an imbalance between calories consumed and calories which are expended. An increased consumption of highly calorific foods, without an equal increase in physical activity, will lead to an unhealthy increase in weight. Also decreased levels of physical activity will result in an energy imbalance and lead to weight gain. It is estimated that one billion adults are overweight and more than 300 million are obese (World Health Organisation 2008). At least 2.6 million people each year die as a result of being overweight or obese (World Health Organisation 2008). Once being associated with the higher income countries, obesity is now also widespread into the lower and middle income countries, as over 65% of the worlds population live in a country where overweight and obesity kills more people than underweight (World Health Organisation 2008). This includes all high-income and middle-income countries. Globally, 44% of diabetes, 23% of ischaemic heart disease and 7-41% of certain cancers are attributable to overweight and obesity (World Health Organisation 2008). 2.2 Body Mass Index The most commonly used measure for identifying if an individual is considered overweight or obese is the Body Mass Index (BMI), is a simple index to classify overweight and obesity in adult populations and individuals. The (World Health Organisation) defines the calculations for BMI as the weight in kilograms divided by the square of the height in meters (kg/m2). The classifications of BMI are underweight (=25.0), pre-obese (25.0 29.9), obese (>=30.0), obese class 1 (30.0 34.9), obese class 2 (35.0 39.9) and obese class 3 (>=40.0). The body mass index (BMI) is the same within both sexes and for all ages of adults. However, the BMI should be considered as a rough guideline as it may not correspond to the same body fat percentage in different individuals. The BMI classification system is not yet usable for children as their bodies undergo a number of physiological changes as they grow. 2.3 Bioelectrical Impedance Analysis (BIA) However bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition (Maughan R 1993). BIA first became available in the mid-1980s the method has become very popular due to its ease of use, portability of the equipment and its relatively low cost compared to some of the other major methods in assessing body composition analysis (Maughan R 1993). In spite of the perception that BIA measures body fat, the device actually determines the electrical impedance of body tissues, which in turn provides an estimate of total body water (TBW) (Maughan R 1993). TBW results from the BIA, can then estimate fat-free mass (FFM) and body fat (adiposity) (Maughan R 1993). 2.4 Exercise Regimes Changes in diet and/or exercise patterns are the primary ways for one to lose weight but a combination of caloric restriction and exercise has been shown to be a more effective nonsurgical intervention (C. Curioni and P.Lourenco, 2005). Recent research from (V. Mougios, et al. 2006) has shown that a combination of exercise and dieting has been more effective to optimize fat loss. Past research from (N. Keim, et al. 1990) agrees with this by stating that a change in diet eases weight loss by limiting the total caloric intake for the day. Caloric and fat expenditure is increased by a change in exercise patterns (N. Keim, et al. 1990). Of relevance, the exercise regime typically employed in an overweight or obese population involves stable aerobic exercise performed at a continuous low to moderately low intensity (Jacobsen et al., 2003). It is undefined whether this form of exercise (continuous), in combination with dieting, is the most effective way to lose fat or to improve general health. Alternatively high intensity exercise burns a larger number of calories when compared with low to low-moderate intensity exercise performed over the same period of time, therefore being more effective solution for fat loss (L. Campbell, et al. 2010, ). Additionally past research from (J. MacDougall, et al. 1998) has shown that high intensity exercise places a larger physiological load on the cardiovascular system compared with lower intensity exercise and therefore may lead to greater results in improvements in aerobic fitness. On the other hand (L. Campbell, et al. 2010) states that many overweight and obese individuals have l ow levels of fitness, the stress which is put upon their bodies by the high bouts of high intensity exercise may be difficult for them, if not impossible. This is supported by Jakicic et al. (2004) who reported the need for obese/overweight participants to divide their exercise sessions into smaller sections due to their incapability of performing a single continuous session of moderate to high intensity exercise. Up to now, certain studies have reported the efficacy of high intensity exercise on various physiological restrictions related to weight loss (Jakicic, Marcus, Gallagher, et al. 2004; Mougios, Kazaki, Christoulas, et al. 2006). In addition, ODonovan et al. (2005) has reported superior improvements in cholesterol, low density lipoprotein (LDL-C) and high density lipoprotein (HDL-C) after research of a 24 weeks period of high-intensity exercise, compared to moderate-intensity exercise. As Interval training includes bouts of high-intensity exercise with stages of rest or lower intensity exercise that allow for part recovery (McArdle et al., 2001), it can be used for most individuals as dependent on their fitness levels the intensity and duration of the interval bouts can be adjusted in order to match an individual, thus making this form of training a suitable option for most people. The studies which have compared high intensity interval training and continuous aerobic exercise in the o bese and overweight population have stated that high intensity interval training resulted in greater fat loss (J. King et al, 2001; E. Trapp et al, 2008). High intensity interval training can be conducted in many forms of exercises from cycling to walking, research from (L. Campbell, et al. 2010) looked at the effects of interval exercise on physiological more specifically into continuous versus interval walking in an obese population, whereas (K. Wallman, et al. 2009) exercise interventions required the participants to exercise on a cycle ergometer (Monark 828e, Sweden) as the reduced strain on the body , would occur via cycling, as an exercise intervention in an overweight population. The research done by (L. Campbell, 2010) stated that potential participants were eliminated if they participated in an excess of 30 minutes of exercise on 3 different occasions per week over the last 6 months K. Wallman, et al. (2009) also stated this. L. Campbell, (2010) also excluded participants if they were ever pregnant, taking medications in relation to beta blockers, blood pressure or a thyroid medication, whereas other research by (K. Wallman, et al. 2009, JW. J. King. 2001, K. Hansen, et al. 2005) didnt look into eliminating participants if they had these advantages. Participants were also excluded if they had diabetes, had a blood pressure (BP) superior than 160/90, had lost more than five kg in the last three months, had musculoskeletal problems that prevented them from walking (L. Campbell, 2010, K. Wallman, et al. 2009). The daily activity data for a week i.e. the number of steps per day was assessed during weeks 1 and 12 of the intervention using a pedometer (Yamax, Dig i-walker, SW-700, Tokyo, Japan) in research by (L. Campbell, 2010). The Yamax Digi-walker pedometer has been reported to accurately and reliably measure steps during walking and running in overweight and obese individuals (Swartz et al., 2003). However other studies did not take into consideration daily activity which is what I did. How different studies measured their results varied as H. Mohebbi, (2011) interventions consisted of the use body mass index and whole body fat mass and free fat mass (FFM) in order to get their results, whereas (K. Wallman, et al. 2009) used the stadiometer for to measure their height and body mass was determined using Sauter scales. Compared with how the intervention that I used to get my results would be the use of body fat percentages from bioelectrical impedance and looking into physiology adaptations by the MSFT. 2.5 Interval Versus Continuous The research results reported by (L. Campbell, 2010) used individuals who there were no significant differences for age, body-mass, height and BMI Prior to the intervention for both groups and there were no significant differences between the two groups for VO2peak (ml ·kg-1 ·min-1) K. Wallman, et al. (2009) also approach their investigations this way. The results by (L. Campbell, 2010, K. Wallman, et al. 2009, K. Hansen, et al. 2005) shown that there were no significant differences between both groups for body mass, fat mass or lean mass at baseline but there were significant main effects for time for body mass and fat mass . Further, while (L. Campbell, 2010) found there were no significant differences between groups for gynoid and android fat mass at baseline or upon the conclusion of the intervention, there was a significant main effect for time found for gynoid fat mass, with reductions in this measure being reflected by large ES in interval and continuous groups. Whereas K. Wallman, et al. (2009) found there was no significant differences, however there was a slight difference in both variables, but results revealed that while there were no significant changes in body mass and android and gynoid fat mass between groups, there was a trend for a decline in android fat mass in the interval group, as established by a large effect size in this group only. Declines in total fat and gynoid fat mass were reflected by significant main effects for time, as well as moderate and large effect in both groups (L. Campbell, 2010). L. Campbell, (2010), K. Wallman, et al. (2009) found that in addition, the decrease in overall body mass over time only was reflected by a moderate effect sizes in the interval group only. These results show that body mass in the interval group are most probable at greater total android fat mass and fat loss in the interventions, as results show interval group are (~22.5% and 28.5%) compared to the continuous group (~17% and 19.2%) (L. Campbell, 2010). Furthermore these results are also support by other similar studies that stated body mass loss (W. Schmidt et al., 2001; J. Volek et al., 2005) and fat mass loss (J. King et al., 2001) after exercise interventions (J. King et al., 2001; W. Schmidt et al., 2001) and also a diet and exercise intervention (J. Volek et al., 2005). K. Wallman, et al. (2009) research looked into the use of a calorie restricted diet when comparing interval versus continuous, while other studies (J. King, et al 2001, K. Hansen, et al. 2005, L. Campbell, 2010) have shown not to directly look into calorie restricted diet. Consequently research suggests a combination of both high intensity interval training and calorie restricted diet has shown beneficial improvement in VLDL-C (L. Campbell, 2010). The studies which have compared high intensity interval training to continuous aerobic exercise in the obese and overweight population have reported that high intensity interval training resulted in greater fat loss (J W. King, et al, 2001; E. Trapp et al, 2008). Nonetheless, the results of the study conducted by (C. Perry, 2008) suggest that further investigation is necessary into the use of interval training on cardiovascular fitness and fat loss amongst an overweight or obese population. C. Perry, (2008) In particular, a longer intervention period, as well as a higher work to relief ratio associated with the interval exercise may result in greater improvements in cardiovascular fitness and fat loss. As the results have shown that interval training appears to be an effective form of exercise when improving aerobic performance and fat loss, (C. Perry, 2008) states that future studies should examine the adoptability and sustainability of a cycling interval training regimen in the overweight and obese population. Furthermore J W. King, et al (2001) indicated that there is a lack of studies investigating high intensity interval training programs as a potential means of weight loss compared with low continuous training. This shows that such rese arch must be conducted to determine if high intensity interval training is a viable means to reduce total body weight and fat mass when in complaisant with low continuous training. 2.6 Summary Even though previous studies exist concerning the effect of high intensity interval training on performance, interval training has yet to be assessed in a shorter duration than other studies which look into the effects of interval training. Most studies look into the effects of high intensity interval training over a period of 8 weeks or longer (Jakicic, Marcus, Gallagher, et al. 2004; Mougios, Kazaki, Christoulas, et al. 2006). These studies have found a significant difference when comparing body fat percentage/Body composition and performance (J. King et al, 2001; E. Trapp et al, 2008). However if an high intensity interval training program is shown to produce changes in body weight and body composition in a shorter time than 8 weeks plus, perhaps that type of program would be more appealing to those who have difficulty adhering to longer continuous steady state exercise programs. 3.0 CHAPTER THREE METHOD The purpose of this study was to compare the effects of high intensity interval versus low steady state continuous training on weight loss and body composition in overweight population. This section will discuss the subjects, instrumentation, research protocol, and the design and analyses that were used in comparing the effects of the two training methods. 3.1 Subjects The primary criterion for subject selection will be that all subjects will be clinically overweight and obese, overweight is classified having an body fat percentage of 25% During the testing the subjects were not be allowed to make any conscious changes in their eating habits. The purpose of the study was to determine the effects of high intensity interval and low intensity steady state training protocols on weight loss and physiological adaptations, any changes in energy consumption would have an effect on this data. For this study there were 8 subjects/volunteers, which were randomized into two different groups using randomized software, these groups being high intensity interval and continuous steady state training groups. The 8 subjects will be randomly drawn into high intensity interval training and low intensity steady state training groups though computer software tools which was also agreed with by participants and the university itself. Prior to the study, all subjects were asked to sign an informed consent form (Appendix A) and Par-Q (Appendix B). The informed consent notified subjects of all potential risks involved, including the possibility of musculoskeletal injury and myocardial infarction (J. King et al, 2001) while the Par-Q gave detailed information about the participants health. The experimental protocol and associated risks were explained orally and in writing form to all subjects before written consent will be obtained. The subjects were told that they would be free to leave the study at any time and that their personal records would be kept confidential. 3.2 Tests and Equipment Each subject completed a 4 week training program, the subjects were told that they would be free to leave the study at any time and that their personal records would be kept confidential. Prior to the study the subjects/volunteers were asked if they are involved in a structured training program and will be excluded from the study if they dont meet the criteria. As this study dealt with the effect of high intensity interval and low intensity steady state training protocols on weight loss, body composition and physiological adaptations, there were be several measures taken. A VO2 max test prior to the study was conducted in order to determine appropriate absolute intensity levels for the subjects. The dependent variables, weight and body composition, was measured at both the beginning and end of the study. Body fat percentage was also recorded both at the beginning and end of the study at similar times in the afternoon. The most precise way to assess aerobic capacity is the direct measurement of maximal oxygen uptake (VO2max) during a graded exercise test (GXT). However, the direct measurement of VO2max is often limited to laboratory, clinical, and research settings. The requirement to assess aerobic capacity in the general public has led to different development of various field based testing. These tests included the multistage fitness test and 1 mile walk test, previous research by (D J. George et al., 1997; P D. Heil et al., 1995; H M. Malek et al., 2005) reported valid estimates of aerobic capacity when using field based VO2 max testing. The multistage fitness was used in this study due to other commitments where all participants couldnt arrive at the laboratorys to conduct the GXT. The 20-m multi-stage shuttle run test (MSFT) is also known as the Leger test, the beep test, the bleep test (Leger, Mercier, Gadoury, Lambert, 1988). MSFT (20-m MSFT, Leger et al., 1988; Leger et al., 1989) is often the most used field based fitness test used when testing aerobic capacities of a person, recent study by (Wong et al., 2001; Mota et al., 2002; Guerra et al., 2002; Vicente-Rodriguez et al., 2003; Vicente-Rodriguez et al., 2004) have used the 20-m multistage fitness test for the measurement of aerobic capacity. The MSFT involved the test subjects to do continuous running in-between two lines which were situated 20 metres apart in time to the recorded beeps. As the test subjects reach the marked line they then stop, turn around by 180 ° and run in the opposite direction towards the other marked line. The subjects were told they must stop when instructed by a beep from a CD. The starting speed of the MSFT is 8.5 km/h and after about a minute a sound indicates an increase in speed (0.5 km/h per minute) (Leger, A L Lambert, J. 1982). As the level increase the time it take for the beeps decreases. The test was stopped when a subject was unable to keep up with the pace dictated by the beep sound, and their score was taken. Throughout the test, the participants had to make sure to cover the set distance and touch each line with their foot before proceeding towards the next line. In order to calculate the predicted VO2 max (predËâ„ ¢VO2 max) for the MSFT an appropriate equations was used (AD Flouris et.al. 2004 L L ´eger, C Gadoury.1989): à ¢Ã¢â€š ¬Ã‚ ¢ MSFT: predËâ„ ¢VO2max = MAS ÃÆ'- 6.592 à ¢Ã‹â€ Ã¢â‚¬â„¢ 32.678 Each subjects was required to attend the exercise physiology laboratory at Wolverhampton university where their height can be assessed using a stadiometer, their mass be assessed and body fat percentage using bioelectrical impedance. However due to time arrangements participants couldnt make it to physiology laboratories for testing, therefore the testing was brought to the participants through the portability of the bioelectrical impedance and a portable stadiometer was used to assess the participants height, also they weight was assessed using scales (Seca 769 Upright Scales). Bioelectrical impedance analysis (BIA) has emerged as one of the most popular methods for estimating relative body fat (National Institutes of Health Technology 1996 V H. Heyward et al., 1996). BIA was first developed in the 1960s; BIA is also relatively simple, quick and portable and is used in diverse settings, including private clinics and hospitals. National Institutes of Health Technology (1996) has shown that the BIA method to have approximately the same accuracy as of the skinfold method in a diverse group as also found by (V H. Heyward et al., 1996 D W. Lockner et al., 1999). Before testing subjects could moderately consume drinks or food, as long as the fluid or food remains within the stomach, not absorbed by body tissue, test results will not be influenced (V H. Heyward et al., 1996). To conduct the BIA all subjects were asked to lie in a supine position on a non-conducting surface, with the arms slightly abducted from the trunk and the legs slightly separated the particular model used was the (Bodystat 1500; Bodystat Ltd, Douglas, UK). The electrodes were placed on the hand and foot of the right side of the body and repeat tests were applied to the same side of the body, new electrodes were employed for each subject. A non-susceptible current then entered the body through the first pair of hand-foot electrodes, and then the second electrode pair is used to determine the voltage drop caused by the body water dependent impedance or total resistance which then determines body fat percentage (V H. Heyward et al., 1996) a few seconds later the test was completed. <

Compare and Contrast London by William Blake and Island Man by Grace Nichols Essay

Compare and Contrast â€Å"London† by William Blake and â€Å"Island Man† by Grace Nichols. Consider How Each Poem Conveys Alternative Attitudes To Life And Society. Introduction The poem â€Å"London† written by William Blake (1757 – 1827) is a clever poem. Although we can appreciate it, and understand William Blake’s ideas, it was not understood or valued when it was written all those years ago. In contrast the poem â€Å"Island Man† written by Grace Nichols is a contemporary poem. The single idea that brings these two poems together is that they are both about the city of London. â€Å"Island Man† is in language that we understand today, Blake’s poem uses the English language of the 18th century. Brief Historical Background William Blake was born in a district of London called Westminister on the 28th November 1757. His obvious artistic talent lead his draper father to enter him into Par’s Drawing School in the strand. This lead on to him later being apprenticed to James Basire, an engraver who worked for the Royal Society of Antiquaries. He married Catherine Boucher in the August of 1972 when he became a freelance engraver. Blake was an accomplished artist in many areas, not only did he write novels and poems, he was also interested politics and religion but he could paint and engrave to a very high standard. Blake was introduced by Joseph Johnson to other radical thinkers of the day including Mary Wollstonecraft, William Godwin, Joseph Priestley and Thomas Paine. In his books such as The French Revolution 1791, and America: A Prophecy 1793. He developed his attitude of revolt against authority, combining political belief and visionary ecstasy. The political situation of the time was such that some of his work was printed anomalously because he feared government persecution. In 1800 Blake moved to Felpham where he began work on his epic poem, â€Å"Milton† and â€Å"Jerusalem†. In these poems Blake reveals his social criticism combined with prophecy and biblical legend. In 1803 Blake was charged with high treason on the testimony of a drunken soldier named John Scofield fortunately he was acquitted and moved back to London. Blake died in obscurity in 1827 and was buried in an unmarked grave at Bunhill Fields. The poem â€Å"London† is obviously drawn from Blake’s own experiences of the London in which he lived. He saw London for the hell hole that it was through the eyes of a man that seemed to feel all the poverty and degradation of everyday life that ordinary people understood. His religious beliefs embraced Unitarianism a very simplistic form of Christian worship which was in direct confrontation to the Church of England and all its values. This sensitive artistic man saw all the horrific abuses in society, and this poem was his way of making people confront the problems. Even though he did not have a solution to the problems, he wanted people to face up to the problems and try to work together to make their society a better place. Main Criticism of â€Å"London† Title Blake chose the simple title â€Å"London† to engage his reader’s interest about their capital city. London was the heart of the country, the city of government. It was a symbol of power and majesty. As the reader would examine the poem however they would realise how ambiguous the title really was. Blake was preparing the reader for a powerful poem, but the power of the poem was in showing the reader how sordid their beloved city really was. Type of Poem This poem is warning the whole of London’s population just how hideous the real face of the city was. Blake was behaving like a prophet advising that people should fundamentally change their way of life. â€Å"Runs in blood down Palace walls† is a caution to people in authority that if they continued on their course of closing their eyes to the poor and the conditions in which they lived, what had happened in France namely the Revolution and the slaughter of the Monarchy making France a republic would happen in Britain. The theme of constraint and social control runs through the whole of the poem. People could not choose how they lived their lives. Subject of Poem & Its Treatment The subject of Blake’s work includes the exploitation of people and their eventual corruption in every conceivable part of society. â€Å"How the youthful Harlot’s curse†. Blake explains here that these young people had no choice but to resort to prostitution. Society corrupted them and they then in turn became sinful and corrupted. Voice The poem is written through the eyes of one person, but this person wants you to experience all the oppression and social injustice that is all around. This person has strong beliefs and is prepared to stand up and speak out for those who are less fortunate than himself. â€Å"I wander thro'† begins the poem and so sets the reader on their own personal journey through the disgraceful city of London. Mood & Tone A desperate and hopeless mood runs through the whole of this poem, it is negative and offers no solution to the terrible torment that the people suffer. â€Å"And mark in every face I meet Marks of weakness marks of woe.† Blake makes no secret of the fact that he sees misery, illness and oppression in every individual that he meets. Form & Structure The structure of this poem consists of four stanzas each of which contains four lines, this is known as a quatrain. Blake chose this arrangement to reflect the idea of control and authority with great effect. The monotonous structure of this poem reflects the way in which life is played out. This poem is very much like a ballad in that it tells a story of a walk through London and the terrible sights to be seen. Blake shows his genius in the third stanza when every first letter of the line spells the word â€Å"hear†, this being the last word of the second stanza. This technique is known as an acrostic, and is usually used in romantic poems, however in this case the poet uses this skill to underline the message of the poem, being that society must listen to his warning of approaching doom. Rhyme The rhyme scheme of this poem is ABAB. It is regular and gives a sense of control. The narrator is obviously sure of his ideas and completely confident in the knowledge that he holds the moral high ground. Rhythm The rhythm of this poem reflects the rhyming scheme in that it is very controlled in order to make the poet’s point of view quite clear. There is a continued steady beat, which seems to reiterate the poet’s ideas. Imagery Imagery features throughout this poem from beginning to end. Feelings and ideas are evoked by Blake’s particular choice of language. â€Å"Every blackning Church appals†. How can the reader not fail to appreciate the distressing nature of this poem when this line is read. A Church should be a place of God, holy and pure. This Church was black, which suggested unholyness, and ungodliness. The blackness underlines the feelings of despair and helplessness A Church should be welcoming, it should not repel people. The blackness of the Church contrasts deeply with the red of the blood that runs down â€Å"Palace walls†. The blood is an image of the violence that is all around. A very strong image is â€Å"The mind-forg’d manacles I hear†. Obviously the people’s thoughts were being controlled; they had no freedom of thought. The image of the physical manacle is powerful when it is used in the context of people’s minds and thoughts being constrained. â€Å"And blights with plagues the Marriage hearse†. We see in this image the death of marriage and the death of family values, marriage is under threat. Married men were known to visit prostitutes. In this final line many ideas are represented, one would not expect the word â€Å"hearse† which represents death and the ceremony of a funeral in the same line as the word â€Å"Marriage† which represents life and the ceremony of a wedding. The word â€Å"plague† in this line conjures up the idea that it is inevitable that society will fall apart, it is inescapable, and the very fabric of society was rotten. â€Å"Marks of weakness, marks of woe†. In this line thoughts of oppression appear on individuals faces. It is noticeable that social injustice has made them weary and downtrodden. The word mark is used to convey two different meanings, firstly how he notices these people, and secondly the physical marks of oppression on the peoples faces. Language The poet chooses the words he uses very carefully to invoke very specific ideas. â€Å"Plague† is a word associated with suffering and helplessness. â€Å"Woe† is used to convey feelings of distress and oppression. â€Å"Runs in blood† makes us think of violence and the brutality of life. â€Å"Harlot’s curse† shows us the negative side of the sordid life in which they lived. These words appear throughout the poem, powerfully showing the ideas Blake feels is his duty to share with society. Techniques â€Å"In every† and â€Å"cry† are repeated. This is to get the point across very forcefully. The effect of the terrible conditions in which people lived stretched across the whole of society. â€Å"Cry† in this context shows their fear, they are not screaming, they are experiencing internal agony. The full spectrum of people were â€Å"marked†. Blake is quite revolutionary in the line â€Å"In every Cry of every Man†. He uses the word â€Å"Man† to mean every ordinary man, they were important. Alliteration is used to great effect in the phrase â€Å"Soldiers sigh†. The words are bound together intensifying the feeling of the desperation that these royal servants felt. In the line â€Å"Marks of weakness, marks of woe† the alliteration strengthens the repetition technique. â€Å"How the youthful Harlot’s curse Blasts the new-born Infant’s tear†. This is an example of enjambment, the rhythm and thought are continued from one line to the other and is reflective of the flow of the Thames that runs through London. â€Å"Runs in blood† is a very powerful metaphor, the idea of oppression is cleverly communicated through this technique. â€Å"Mind-forg’d manacles† is used to illustrate just how oppressed people felt not only in body but also in spirit. The poem starts with the personal pronoun â€Å"I†. The poet wants us to understand that he has strong personal beliefs contained within this poem. He is prepared to stand by these beliefs and try to make the reader understand his views on society and social justice. Blake puts the words â€Å"Man†, â€Å"Chimney-sweep†, â€Å"Church†, â€Å"Soldier† and â€Å"Palace in capital letters. Here he is emphasising the importance of every section of society, and how each word symbolises every section of that particular status. Senses The poet appeals to our sense of sight and sound in his poem. In stanza one the sense appealed to is visual talking about the river Thames and the streets of London full of business activity. Blake concentrates on the physical surroundings. One stanza is in direct contrast to the other. The word â€Å"cry† is repeated several times, this together with â€Å"Soldiers sigh† gives the reader an understanding of the pitiful sounds that surrounded the poet as he journeyed through London. The poet wants us to listen to everything he says, he emphasises this in the third stanza with the first letter of every line spells the word â€Å"hear†. Our sense of sight cannot help but be engaged by â€Å"Every blackning Church†. Black is a colour associated with evil and bad happenings. Tenses The poem was written in the present tense. All the sights and sounds he experiences are happening now and need to be addressed immediately. Society needs to examine itself and change. Punctuation is used by the poet to control the rhythm and the pace. The commas are used to list the many problems that are witnessed â€Å"In every voice, in every ban†. The poet also uses other techniques of punctuation such as a colon in the line â€Å"Every blackning Church appals:†. This is to differentiate between two different subjects being the Church and the Monarchy, it is to make clear who he is accusing of being hypercritical and who he is accusing of being violent. The Effects on the Reader The effects on the reader are quite profound, we are left reflecting and wondering what is really going on in society. Blake hoped his poem would make a difference and reach people who could make society a happier and fairer place to live. He offers no solution towards the end of the poem, but hopes that others would think about the problems that he sees and make some effort towards change for the better. Brief Historical Background Grace Nichols was born in Gorge Town, Guyana in 1950. She grew up in a small coastal village and moved to the city when she was 8 years old. As a child she lived through the countries struggle for independence. She has worked as a teacher and a journalist and has a strong interest in Guyanese folk tales. Grace arrived in Britain at the age of 17, bringing with her the warmth of her Caribbean sensibility. Her poems celebrate sensuality and generosity, and attack petty mean-spiritedness. She has won many awards and prizes and is especially noted for her contribution to children’s literature. The poet spent her informative years in the Caribbean and so sees London in a different perspective from someone who has lived there all their lives. Grace Nichols also has a completely different cultural background to someone who has been brought up in London. Main Criticism of â€Å"Island Man† Title The title represents solitude and isolation, an island represents a place of escape and provokes feelings of a natural environment. â€Å"Man† is universal; it is anonymous and could mean any single man. We see here the similarities with Blake’s poem London in that his poem is from the perspective of an anonymous man. Type of Poem The poem is about a man who has a dream about a beautiful island, he would love this island to be his reality, however his reality is â€Å"Another London day†. The theme of pleasant solitude and peaceful isolation runs through this poem. There is a free lifestyle and a sense of liberty that combined with naturalness makes this poem easily readable. The poems are both concerned with the reality of London life. They maybe set at different times, but they both set in the same city and both are dissatisfied with London life. Subject of Poem & Its Treatment The subject of Grace Nichols poem is the wonderful quality of life on an island compared to the â€Å"dull† lifestyle of contemporary London. More than half the poem is taken up with the description of the island, we wonder therefore if the poet would rather be on the island than in London. The poet has experienced two different ways of life and seems to prefer the island life. In Blake’s poem however, Blake doesn’t seem to have experienced another way of life, his poem just concentrates on the appalling conditions f London. Voice This poem is written through the eyes of one person. This person wants you to understand just what its like to live on a beautiful island and then come back to the â€Å"dull† reality of their life as it is now. Mood & Tone The mood of this poem is one of longing. The poet wants to escape into her fantasy of island life. The fantasy is in stark contrast to her life now. Her sense of hope emerges when she describes the island; â€Å"breaking and wombing† is a phrase that reflects on nature and natural happenings, it gives hope. Despair seems to return when she describes London. The sadness appears in the poem when the dream ends, and he wakes up to reality, â€Å"island man heaves himself† he is weary before the day even begins. This is in stark contrast to Blake’s poem where desperation and hopelessness for everybody runs through the poem. In Grace Nichols poem, island man feels sorry for himself because he hasn’t got the quality of life he wants. Form & Structure The structure of this poem is random; it is obscure and has no particular form. It is purposefully freestyle and reflects a modern poem. The distinct irregularity and variety of each line length is planned. It reflects island life which isn’t planned. This is in distinct contrast to Blake’s poem which is in the form of a quatrain. Rhyme The part of the poem that deals with island life has no rhyme, however when we come back to London in the third stanza we see one rhyme â€Å"soar† and â€Å"roar†. This suggests that there is some structure and control to reality of city life. These words have an aggressive violent sound, they seem to symbolise the aggressive life of London. This is a contrast with Blake’s poem which has a rhyme scheme of ABAB which helps him to convey a sense of controlled aggression throughout his poem. Rhythm The rhythm of this poem reflects the poet’s thoughts. A dream follows no set pattern, and neither does this poem. This contrasts with Blake’s poem which is very controlled and obviously not a dream but a living nightmare. Imagery Imagery features throughout the poem. Feelings and ideas are evoked by Grace Nichols particular choice of language. â€Å"Morning† this is the first line of the poem, just one word. â€Å"Morning† conjures up images of a hopeful start to the beginning of a new day; there might be new opportunities in the new day ahead. â€Å"Wombing† is a word that invokes feelings of a safe environment. He is surrounded by the sound of â€Å"blue surf† and is in a womb of his own making. Feelings of the continuing cycle of life are reflected by the use of this word. â€Å"Wild seabirds† is written again on its own line to emphasise the importance of nature, they were completely free. However nature worked in harmony with inhabitants of this island, fishermen were a fond memory of â€Å"island man†. The poet highlights the fact that the sun rises in the â€Å"east†; the sun is a symbol of life giving and newness, the light of a new day. The â€Å"east † symbolises an area of beauty and mystical ideas. Some religions pray facing east, this is a very positive idea. â€Å"His small emerald island†. Emeralds are very precious gems, they are beautiful and unique like the island to the island man. The island is his treasure, his to own, he belongs there. The memory of his island enables him to exist in the realities of city life. His frequent dreams and thoughts always bring him back to where he believes he really belongs. When the poem comes back to reality the images are of â€Å"grey metallic† sands, these are not natural. We are reminded of the grey and dismal polluted streets of London. It was not a natural environment. The use of the word â€Å"North† has connotations of coldness and harshness. The â€Å"North Circular† is a road that the inhabitants of London travel around, it is a controlled motorway and symbolises the hectic pace of city life. A circular road around the city makes the reader think that island man is now in a life that he can’t get out of. In Grace Nichols’s poem there are many images of nature, quite unlike Blake’s poem where even the river Thames is exploited and controlled. The seabirds were â€Å"wild† they were completely free, quite unlike Blake’s poem where there were â€Å"mind-forg’d manacles†. In Blake’s poem there is no escape from the realities of life, of the helplessness and despair that surrounded him. In Grace Nichols’s poem she has an escape, she escapes into her dreams. Language Grace Nichols uses the language of today. She uses modern words such as â€Å"groggily† and â€Å"muffling†. Blake would have had no idea what these words would have meant. She uses words to contrast ideas such as the â€Å"east† representing island life and the north representing London life. Grace Nichols is not as detailed or aggressive as Blake but they do have the same attitude to London life. â€Å"Blue surf† represents island life whilst â€Å"grey metallic† represents London life. The whole of Blake’s poem consists of negative language over half of Grace Nichols’s poem, the part that deals with island life consists of positive language. Techniques Grace Nichols uses the repetition of the word â€Å"groggily† to move from one part of the poem to the other, it is a turning point; it separates island life from reality. Island man does not want to leave the island, it is an unpleasant experience in which the island man is confused. Repetition is again used in â€Å"Muffling muffling† to emphasise the fact that although his dream was clear, real life is confusing. Blake also uses a repetition technique, but he uses it to convey his ideas. An example of alliteration in Grace Nichols’s poem is â€Å"sun surfacing†. This paints a picture in the reader’s mind of the sun rising over the water, a very powerful image of island life. Blake again uses alliteration in the same way to evoke effective images. Enjambment is used to great effect, the poem is at random with irregular lines to reflect the randomness of a dream and the confusion felt well awaking. Blake’s poem also has thoughts running from one line to the other. The poem â€Å"Island Man† is written in the third person, it communicates a sense of detachment and could well be someone else’s experience, there must be many people in London who are away from home and feel a sense of isolation even tough they are surrounded by hoards of people. In comparison Blake’s poem was written in the first person making â€Å"London† a more personal poem. The same senses are evident in both poems, each of the poems only deal with sight and sound, but are treated in different ways. The poem â€Å"Island Man† sights and sounds are linked â€Å"sound of blue surf† gives the reader an idyllic image of a perfect island beach. In the poem â€Å"London† the whole of the first stanza is concerned with sight and the whole of the second stanza is concerned with sound. Tenses The poem â€Å"Island Man† is written in the present tense in modern-day London. In comparison the poem â€Å"London† although also written in the present tense is concerned with 18th century London. Punctuation Grace Nichols’s technique of using absolutely no punctuation what so ever is very effective, it communicates the idea of freedom and a dream like state. There are no rules in this poem, thought continues from one line to the other. â€Å"His crumpled pillow waves island man heaves himself†. This is in direct contrast to Blake’s poem which is ruled by punctuation. The poem has either a comma, full stop or colon. Effect on the Reader â€Å"Island Man† in the first half of the poem is very bright and cheerful and shows a very natural and free way of life, which every reader could identify me with and would hope to aspire to. The second part of the poem deals with the reality of London life again, which many people can identify with. In contrast Blake’s poem â€Å"London† is a very gloomy poem all the way through.

Why Cigarette Smoking Should Be Banned

Cigarette smoking should be banned. Cigarette smoking is a dangerous habit that not only affects the user in a negative physical and psychological way but also endangers others around them. Would you play Russian roulette – A deadly game of chance involving a revolver and a single bullet– and then force others around you to participate? Cigarette smoking has detrimental effects on both the user and innocent bystanders effectively initiating a game of Russian roulette. Considering the dangers of cigarettes, banning them could potentially protect society from their dangerous effects.The physical effects of smoking are quite frightening and include a wide variety of diseases. These include but are not limited to: cardiovascular disease, respiratory disease, and a wide variety of cancers. A common outcome of the more serious tobacco related diseases is death. It is noted on the CDC (Centers for Disease Control) website that ‘More deaths are caused each year by tobacco than all deaths caused by HIV (Human Immunodeficiency Virus), illegal drug use, alcohol use, motor vehicle injuries, suicides, and murders combined. (CDC – Fact Sheet – Tobacco-Related Mortality – Smoking & Tobacco Use, 2011) With all this evidence pointing to the physical dangers of cigarettes, why then do people continue choosing to engage in this behavior? Perhaps the psychological effects of cigarettes can account for the continuation of their use. Cigarettes can have not only a stimulating effect, but also a perceived calming effect and can also induce feelings of euphoria. Nicotine in tobacco causes these perceived effects and feelings.Nicotine is a psychoactive drug found in tobacco products, and it is this chemical that causes users to develop a dependency on cigarettes. One particular cause for alarm is taken from the CDC website. ‘Research suggests that nicotine may be as addictive as heroin, cocaine, or alcohol. ’ (CDC – Fact Shee t – Smoking Cessation – Smoking & Tobacco Use. 14 Nov. 2011) With this in mind, we now start to understand the psychological dangers of smoking cigarettes. The addiction compels the user to continue smoking.Having looked at the physical and psychological effects of smoking on the users, let us now take a look at how detrimental cigarette smoking is to non-smokers. Cigarette smoking is extremely dangerous to non smokers. Secondhand smoke is a mixture of side stream smoke — smoke from the end of a lighted cigarette—and mainstream smoke—smoke exhaled by a smoker. This secondhand smoke contains 250 known harmful chemicals of which 60 are known to cause cancer. This dangerous concoction of chemicals in the smoke puts those that have chosen not to smoke in harm’s way.According to the website of the American Cancer Society, each year, second hand smoke is responsible for ‘an estimated 46,000 deaths from heart disease’, â€Å"About 340 0 lung cancer deaths’, and ‘Between 150,000 and 300,000 lower respiratory tract infections in children’. (â€Å"Secondhand Smoke. â€Å", 14 Nov. 2011) The list carries on, but we can now see how cigarette smoking not only affects smokers, but non smokers too. As detrimental as cigarettes are to everyone’s health, there are still those that claim it is their right to be able to smoke.Opponents of cigarette banning claim that it is their civil right to choose to smoke and that society does not have the right to dictate what people do to their bodies, regardless of whether it is unhealthy for them or not. They claim that if the government bans cigarettes on the basis that it is harmful to one’s health, then they may as well ban other things that pose a health risk, like â€Å"junk food†. The problem with this argument is that while eating junk food does pose a health risk to the person eating it, there is no immediate health risk to the peopl e around them.Even governments have started to recognize the dangers of cigarettes by allocating smoke free zones where smoking is not allowed. Even though this is a step in the right direction, it still does not keep everyone safe from the dangers of cigarette smoking. By examining the all the information, it is easy to see that cigarette smoking is particularly dangerous on both physical and psychological levels while also needlessly endangering non-smokers. Could the banning of cigarettes potentially wrestle the revolver from the hands of the smoker and finally put an end to this dangerous game of Russian roulette?

Essay on What is Global Warming - 1232 Words

The truth is you dont know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed. The film An Inconvenient Truth shows us what will happen in the future if we continue to produce waste and pollution. We are the cause of global warming. Global warming turns the earth into an oven. Each year the overall temperature raise, causing more natural disaster and dry lands. If we let this continues, we might even end up in the same wasteland shown in the film Wall-E.
