Modern Sedentary Lifestyle On Overweight And Obesity Physical Education Essay

Modern Sedentary Lifestyle On Overweight And Obesity Physical Education Essay Currently, obesity and overweight is a main global health problem plaguing almost the whole planet. Studies show that in 2005 1.6 billion adults were overweight and 400 million adults were obese. As it is portrayed, obesity and overweight is a problem of the contemporary societies that cannot be confronted. According to a recent study of the World Health Organisation, it is predicted that there will be 2.3 billion overweight adults by 2015 in the world and more than 700 million of them will be obese. Also it is important to realise that obesity and overweigh are modern problems of the societies since statistics referring to these problems did not exist 60 years ago. Therefore, it is clear that obesity and overweight apart from genetic predisposition and psychological disorders might derive as well from the modern sedentary lifestyle that is highly affected by the recent technological development and from poor nutrition as there is an increase in convenience food. However in order to understand the extent and significance of the problem it is important to define and analyse overweight and obesity. Obesity can be defined as a medical condition in which body fat has accumulated to the extent that it has a negative effect on health. A healthy body requires a minimum amount of  fat  for the proper functioning of the  hormonal,  reproductive, and  immune  systems, as  thermal insulation, as  shock absorption  for sensitive areas, and as  energy  for future use. But the accumulation of too much storage fat can impair movement and flexibility, can alter the  appearance of the body and cause health problems. Obesity increases the likelihood of  various diseases like heart disease,  type 2 diabetes,  breathing difficulties during sleep (pulmonary diseases), hypertension, certain types of  cancer, and  osteoarthritis. In particular, cancer of the colon as well as prostate in men and cancer in breasts, ovaries and cervix in women have been found to be related to obesity. Furthermore, hypertension has been found to be related CHD and strokes. As a result, obesity has been found to reduce  life expectancy and be one of the leading  preventable causes of death  worldwide. Investigators have estimated that if everybody had the optimal body mass there would be 3 years added to life expectancy, 25 percent less coronary heart disease and 35 percent less congestive heart failure and brain infection. Overweight is generally defined as having more  body fat  than is optimally  healthy, without reaching the body fat value for obesity. The generally accepted view is that being overweight causes similar health problems to obesity, but to a minor degree. It is estimated that the risk of death increases by 20 to 40 percent among overweight people and that being overweight at age 40 reduces life expectancy by three years. Being overweight or obese has been identified also as a cause of  cancer. Psychological well-being is also at risk in the overweight individual due to social  discrimination. However, children under the age of eight are normally not affected. The prevalence of obesity and overweight is strongly related to age. The 16 to 24 years age group (for both men and women) is substantially less at risk of  becoming obese than older age groups. Those aged between 25 and 34 have the second lowest rates of obesity and overweight. Middle aged people are those who are in the most risky position of becoming obese or overweight. In order to further understand obesity and overweight it is important to analyse the methods used in order to classify and tell the degree to which a person is overweight or obese. The most popular method used is that of  the Body Mass index  (BMI), or  Quetelet index. The Body Mass index is a statistical measure of body weight based on a persons weight and height. Though it does not actually measure the  percentage of body fat, it is used to estimate a healthy  body weight  based on a persons height. Due to its ease of measurement and calculation, it is the most popular diagnostic tool to identify weight problems within a population, usually to classify adult underweight, overweight and obesity. Body Mass Index is found by dividing the body mass in kilograms by the square of height in meters. This technique can also act as a health since it appears to provide relative results concerning the degree of risk associated with overweight or obesity. Mortality and morbidity start increase at high rates at a BMI of more than 25. Therefore the desired levels of BMI are those below 25. Below there is a table of the BMI classification according to the World Health Organisation confirming what was previously stated. Classification BMI(kg/m2) Underweight

The Unspoken Dangers of Tanning Beds Essays -- Expository Essays Resea

The Unspoken Dangers of Tanning Beds Tanning beds are devices that emit ultraviolet radiation (UV rays) in order to darken one’s skin complexion. It is believed that approximately 28 million Americans are tanning indoors, in some 25,000 tanning salons nationwide (http://www.fda.gov/ cdrh/consumer/tanning.html ). The rising popularity of tanning beds came about a few decades ago when the media and society started emphasizing that bronzed skin was â€Å"in.† A variety of people use tanning beds, both men and women, and for a variety of reasons; some use them as a weekly (or even daily) routine, others use them seasonally (when it’s hard to get a tan in the winter) and then of course there are the â€Å"event† tanners who go before a big event like a prom, wedding or spring break cruise. Media and what it implies about today’s culture has a massive pull factor on what American people buy. Also, the effects of peer pressure cause people to tan in tanning beds; if the majority of your peers are doing it, then you don’t want to be the only pale kid on the block, despite the consequ...

Racism in the Tuskegee Experiment Essay

The Tuskegee experiment, begun in 1932 by the United States Public Health Service in Macon County, Alabama, used 400 black men who suffered from advanced stages of syphilis.   This study was not a means of finding a cure; the patients offered no preventative measures to prolong or better life.   Although the history and nature of syphilis was well understood, certain scientists believed that more research could certainly be done. In terms of whom to study, the doctors developing the format discovered a â€Å"ready-made situation† (Jones 94). Macon County Alabama was impoverished, like much of the country in 1932.   The selection process began during the depression, a time of separation and intolerance.   In the rural South, where we find Tuskegee, the men chosen were not seen, at the time, as equal in any sense of the word. Jones refers to prominent doctors of the region who, in the late 1800s, scientifically defined diseases that were peculiar to the race.   One such disease, Cachexia Africana, caused the subject to eat dirt.   The public did not question such obviously ridiculous claims at the time.   In fact, the public heralded these doctors and requested a manual for treating blacks in order to save slave-owners and the like money in paying for doctors (17).   Given the distaste for the ethnicity of the subjects, could their ethnicity have been a factor in the selection process? At the time, the medical profession had already made some false assumptions about the African American race in general.   Jones reiterated the white-held theory that black men had larger penises and little constraints when it came to sexual intercourse (23).   It was also believed that they were harder to treat for syphilis because African Americans were stupid. In examining this mindset, it becomes clear why the government erringly felt it should go to the poorer black communities in rural Alabama conduct a syphilis study.   Believed to be an immoral sex-centered culture placed at the level of animals, the government would put them in league with mice and rats.   As disgusting as the premise is, the doctors needed lab animals and set out to find them. If this were true – how could the government get away with it?   Blatant disregard for humanity and life could not go unnoticed.   However, the geographical area in question had just been the last state of the union to discontinue chain gang use in its penitentiaries in 1928.   The South had not yet begun to consider African-Americans as people – not in the slightest meaning of the word. Jones reiterates the sentiment of the doctors at the time and place with, â€Å"short of a ‘quick-fix’ by science requiring no behavior changes by blacks, there was no hope for the race† (26). The Health service claimed they informed the subjects of their disease, although an internship at the time the experiments began, Dr. J.W. Williams, stated the men received no such information.   He also claims the internships registered the data collected without understanding the nature of the experiment either (Jones 5). The term ‘racist’ as defined in the Random House Webster’s College Dictionary reads, †a belief or doctrine that inherent differences among various human races determine cultural or individual achievement, usually involving the idea that one’s own race is superior† (1072).   Given this definition, it is clear that the Tuskegee experiments were racist.   To withhold the nature of the experiments from the subjects, the name of the disease, the treatment of its symptoms and to feel no remorse in inflicting this sort of medical indictment on fellow human beings is not just racist, but also immoral and unjust. Jones points out the Health Services did investigate the treatment of these patients in an Ad Hoc committee.   The resulting medical treatments for the wives and children of the male subjects was offered with no cash restitution allowed (214).   In the end, the government did agree to $10 million dollars in payments to the â€Å"living syphiltics†, the next of kin for those already dead, â€Å"living controls† and the next of kin for the dead controls.   If you had been living with the disease and never treated, you would get a grand total of $37, 500; a paltry amount for the pain and suffering from neglect and racist bigotry (217).

Personal Narrative Just A Game - 721 Words

The cheer of the crowd and the laughter of the kids in the air were the only things reminding me that it was just a game. Eight and a half innings, seven pitching changes by both teams, twenty-seven runs scored in all, and we were still losing. The sweat came dripping off my nose and forehead like melting ice. My eyes stung, and I could barely keep them open due to the bright rays of the sun beating down on the dirt and grass, the baseball diamond seemingly larger than it had been eight and a half innings ago. My coach’s whisper rang through my ears. â€Å"Only if you think you can,† he said so softly that I had to almost lean in to hear what he said. I was on third base, with the winner of the game was being decided by one out. We had made†¦show more content†¦I did not understand why I had to get back to third base because the batter had fouled the ball off, so the play was dead. The third baseman had the ball in his glove, and he slammed it into my back. â⠂¬Å"Whoa, man,† I spat at him with a bit of hatred coming out of the statement. â€Å"It was a foul ball, bud.† â€Å"Oh, my bad,† he replied with sarcasm that slapped me as hard as he did with his glove. As I got ready for the next pitch, I had realized that the count was one and two. My teammate had one strike left before we lost the game. I racked my brain to figure out how I should get home safely, and decided to just go for it. As soon as the pitcher got in his stance, everything changed to slow motion. I was focused on the pitcher’s right foot to where it was going, and as soon as I knew he was going to try to pick me off, my body shifted towards home and I lunged at home plate and ran as fast as possible. My legs churned like train rods, the train hauling towards its destination. As I got within ten feet of home plate, I dove. At one point, I was all the way in the air, my arms reaching out for the one thing that mattered most at this point. I was f alling, and I heard someone shout, â€Å"Tag him.† I needed to touch home before they tagged me. I reached so far, I felt like my arm almost came out of my socket. And everything stopped.
