Type 2 Diabetes And Effects Of Exercise Physical Education Essay

Type 2 Diabetes And Effects Of Exercise Physical Education Essay There are two types of diabetes that normally affects people. The first one is type 1 diabetes and is the most common especially among the young generation. This is caused by inability of the body to produce enough insulin. The second one is type 2 diabetes which is the main focus of this research paper, and is most prevalent among the older population. However in the recent past, more cases are being recorded for type 2 diabetes among the young -adolescents. It is characterized by not only lack of enough insulin production, but also insulin resistance. The risk of developing type 2 diabetes in the adolescents has been further increased by the changing lifestyles. In the recent years, there has been a significant rise in consumption of fast foods. This has led to prevalence of obesity and thus the body requires higher amounts of insulin in offsetting the body demands for complete use of food for energy. However, more complications have resulted due to decreased physical activities. In this era of Information technology, people have retreated to playing internet games and watching television as their means of spending time unlike in the past. Hence, the rapidly changing lifestyle to physical inactivity counts a lot. Mag (2000). states that insulin resistance may also be induced by natural phenomenon such as pregnancy. Mostly type 2 diabetic patients are not treated by exogenous administration of insulin as it is mostly caused by obesity and physical inactivity. Although the genetic factor of the family counts, it counts to a little percentage. NAME states that eight percent of type 2 diabetic patients are obese land the disease may prevail for a long time without being noticed. For instance, Mag (2000) notes that in a study conducted by Mokdad from 1991to 1998 in the U.S., reported cases of obesity had gradually increased regardless of gender, race, sex, level of education, age, and the smoking of individuals. It was further found out that the percentage rate of increase in the same period ranged from 12.0% to 17.9%. Type 2 diabetes and exercise Consequently, the hyperglycemic conditions of type 2 diabetes bring about micro- and macro- vascular complications especially to key organs of the body -kidneys, eyes and heart. Persons with type 2 diabetes are more predisposed in developing cardiovascular diseases than those without. They mostly posses quite number of cardiovascular diseases risk factors and such include, hypertension, and dyslipidaemia (-increased serum triglycerides and low contents of high density lipoprotein). However, a lot of regular exercises have been found to significantly reduce the risk for developing cardiovascular diseases through physiological and metabolic mechanisms (Mag, 2000).The health benefits accumulate proportionally to the intensity of the physical activity. NAME states that a remarkable dose-response relationship between the intensity of exercise and the improvements in the risk factors of cardiac diseases. Physical Exercises in the Prevention of Type 2 Diabetes to in persons at risk Appropriate life interventions -physical activity and weigh loss- can possibly prevent and / or delay development of type 2 diabetes. Mag (2000) documents that certain life intervention study which was carried out on type 2 diabetes risk group. The life intervention program consisted of a weekly physical activity of at least 150 minutes and 7% loss in body weight. At the end of the study, the incidence of developing diabetes was found to decrease by at least 58% regardless of gender, race and age group. Besides, the study group demonstrated a significant decrease in glycosalated hemoglobin and they also found that during the three year treat period, one in every seven persons was prevented from developing the disease and its complications. Physical exercises and Insulin Resistance Regular physical activities have been found to have long term effects on the insulin sensitivity of the in a diabetic person. They improves and brings to normal levels both the insulin response and sensitivity for normal glucose utility in the body. Physical exercises compel the body to use excess glucose for muscular activity. These results in reduced plasma glucose levels and the conditions may prevail for a certain period of time if the physical exercises are continual. It has been found that sufficient time as well as intensity of the physical activities leads to prevention and/ or correction of physiological and biochemical changes of the body that is mostly common in sedentary life. Physical activities deplete the body of its excess glycogen stores and thus increase insulin sensitivity. It does so by compensating the amounts of lost glycogen during the muscular activities. Therefore type 2 diabetic patients improve drastically the metabolic activity of their bodies (Ivy, 1997). According to Henriksen (2002) both acute and continual physical activities leads to improvement of insulin-initiated glucose metabolism especially in type 2 diabetic patients. Further studies by Segal et al. (1991) shows that constant exercise of can largely improve body metabolic activity in spite of weight reduction as earlier stated. Zierath and Henriksson H (1992) states that these recorded improvements in metabolic activity can be attributed to a decreased rate in peripheral insulin resistance and/or increased insulin sensitivity that accompany physical exercises. In addition to physical activity, it has been observed that persons who maintain lean muscle and fat mass, experiences an increase in insulin resistance. Regular physical activities, in terms of time and intensity, results in reduced basal and glucose initiated insulin concentration in the circulatory system. Further, 26 states that there are significant increases in insulin-stimulated glucose consumption rates upon physical training. Exercise and Dyslipidaemia Continual physical activities are normally associated with remarkable effects on glucose control, contents of blood lipids, and functions of the heart and lung. Zierath and Henriksson H (1992) in thair work found that the effects of physical exercises draw a parallel with age of a person, whereas levels of lipid in the blood are dependent upon the body weight. Thompson et al. (quoted by Mag, 2000) documented that following sufficient physical exercise, triglyceride levels reduces within 18-24 hours and this condition is steady to induction of changes in metabolic activity which may persist for up to three days. Besides, they also found physical exercises to drastically increase the High Density Lipoprotein cholesterol levels. Thus, this parallel increase in High Density Cholesterol versus a reduction in triglyceride levels can be interlinked to the same metabolic activity. Mag, 2000 states that Low Density Lipoprotein levels decreases by at least 5-8% in persons with high level chole sterol content after physical exercises. Physical Exercises and Endothelial Dysfunction Research study has found out that to significantly decrease cardiovascular risk factors especially in type 2 diabetic patients. 17 in his research study on type 1 and type 2 diabetic patients found out that physical exercises rectifies metabolism besides the endothelial dysfunction factors such as thrombomodulin, vWF and PAI-1. Therefore it is possible that improvements in endothelial dysfunction factors may be correlated to the protection accorded by physical exercises on the endothelium. Stewart (2002) writes that the coexistence of type 2 diabetes and high blood pressure is particularly damaging to the soundness of the vascular system. He states that most of the studies on the effects of physical exercises have been concentrated on reduction of regulation of glucose content and hypertension. Thus he further states that there is little known about the impact of physical exercises on cardiovascular consequences of type 2 diabetes 0on and hypertension. In the documented work of Stewart (2000), it is stated that, Type 2 diabetes and hypertension result in abnormalities in central and peripheral parameters of cardiovascular structure and function. Evidence for an exercise training benefit is strongest for improvements in endothelial vasodilator function and left ventricular diastolic function. The data for exercise trainings improvement of arterial stiffness and system inflammation and reduction of left ventricular mass are less robust. However, this assertion is based more on a lack of randomized controlled trials rather than data to the contrary. Exercise training also reduces total and abdominal fat. These changes in body composition mediate improvements in insulin sensitivity and blood pressure and may improve endothelial vasodilator function. The current evidence, albeit not fully confirmed in randomized trials, suggests that the benefits of exercise training go beyond the recognized benefits of glycemic control and blood pressure reduction. Therefore, with the current trend of type 2 diabetes, it is imperative to stress the need of physically active lifestyle although it is a big challenge with advancement of technology. Programs of physical activity can be successfully implemented in school programs and at home especially for children/adolescents (Carrier L Herbert L, 2004).

To What Extent Does Trade Help Reduce Development Disparities

To what extent does trade help reduce development disparities? The Republic of Malawi in the southeast of Africa is a landlocked country in which 85% of the people are employed in agriculture. About 90% of all farmers are smallholder farmers that suffer from low income and underdeveloped techniques. This is just one example of underdeveloped countries all over the world. The question is simple: How can these LEDCs develop? One approach of reducing development disparities is the mean of trade – the business of buying and selling commodities either within a country or between several countries.Several countries have already initiated techniques to help LEDCs develop. China for examples encourages Chinese firmst to invest in poorer nations and opens ist own markets to imports from underdeveloped countries. This global foreign investment is a great opportunity to create development opportunities for LEDCs, especially because China itself has just had an extreme financial rise so t hat it is able to help others now. However, critics may think that China – by opening up its markets – rather sees its own benefit, as it secures raw materials and markets for Chinese manufactured goods.Furthermore, China gets richer and its global importance raises drastically. Experts expect it to overtake Japan’s economy soon. Very different to this rather unfair approach of reducing development disparities due to trade is established by the FAIRTRADE foundation. This development organisation helps countries in the developing world to improve several different aspects such as sustainable prices for products that never fall under the market price, decent working conditions or fair terms of trade.To achieve this, specific FAIRTRADE certification and product labelling was developed called the FAIRTRADE mark – an independet consumer label. Things like the FAIRTRADE minimum price, which means that a buyer has to pay a certain price that is fair to the produ cer or FAIRTRADE premium, which means that the money payed on top of the minimum prize is spent on social, environmental and economic development projects. Neither pretending to help nor really trying hard to boost LEDC’s economy, he three nations USA, Canada and Mexico agreed on the „North American Free Trade Agreement which was set up in January 1994. The „Theory of Comparative Advantageâ€Å" shows the intention of this association of nations: As they were all economically challenged by western Europe and Asia and as the completion of internal market of the EU harmed their economy, it is obvious that with an elimination of trade barriers due to the NAFTA, these countries would all benefit from it in their economic situation.The aim the NAFTA is to eliminate trade barriers, promote economic competition, increase investment opportunities and improve cooperation between the USA, Canada and Mexico. Acualizing these aims will have several impacts on the worldâ€⠄¢s economy. One example therefore ist he potential wage and benefir reduction in the US due to Mexico’s membership. Also, Mexico would have to adopt higher foreign standards and poor Mexican farmers have now to compete with large-scale, high-tech US- or Canadian farmers. These are just some examples of the impact that the free trade treaty has on its members.Although the idea of free trade troughout nations seems auspicious, it clearly has its weaknesses as well. Concluding, the NAFTA has a good approach which however is not helping LEDCs develop further and rather makes it difficult for – in this case – Mexico to keep up with its partner-trading-nations USA and Canada. Governments from developed countries try to make LEDCs help themselves by researching and setting up various organisations in order to make trade easier. One example of this so-called „top-down approachâ€Å" is provided for farmers in Malawi.The aim of government-led projects is to allow african farmers being self-sufficient and develop their own business with enough income. A peanut farmer in Malawi is now – due to the support of the British government – able to sell his peanuts to big oversea markets. As it is difficult for little farmers to access those big markets, buying centres were build by the foreign government in order to allow the farmers easier access. Some farmers then use their income to open bank accounts, start new businesses and put their children through secondary school.In this process, they break out of the „vicious circleâ€Å" of poverty. Critics still see problems in this government-led approach as farmers are not concious about being helped to a great extent. In the project of for example Malawi, the British government gets highly involved in the economy of a country which often is seen from a negative angle by the population as they would like to manage their economic structures on their own. However, this „bottom -upâ€Å" approach to less economically developed countries by its own population is standing in great contrast to the government-led approach.As certain people of the country would have to mobilise its people and due to lack of financial support, often resignation by the population limits the development of a country. Several very different approaches towards reducing development disparities were made by governments and foundations. These can be easily contrasted: They are either initiated by a country or nation so as to extract the countries benefits out of trade or in order to help and support another country in its development by providing aid for it – this government-lead approach is called „top-downâ€Å".The contrast to this approach is called „bottom-upâ€Å" and is lead by a countries‘ own population which is a rather difficult process. Generally, trade is a very good way of linking a nation’s economy, as mostly contracts between countries are established so that both parties benefit from the business. This means that LEDCs can develop and change their status to MEDCs. However, as it is in the nature of the human species to always be best and leading, LEDCs must be very cautious not to get exploitet by economically powerful nations such as China.

Annenberg Pubic Policy Center Case 25. 1 A study by the Annenberg Pubic Policy Center investigested one major area of business decision :pricing practices. Specificially,the study addressed consumer knowledge and attitudes about the practices of online retailers adjusting their prices according to customer characteristics,such as how frequency they buy from the retailer. For example ,a website selling cameras charged different prices for the same model depending on whether visitor to the site had previously visited sites that supply price comparisons.In general,charging different prices is called price discrimination and legal unless it discriminates by race or sex or involes antitrust or price-fixing laws . The Annenberg study consisted of telephone interviews conducted with a sample of 15,000 adult,screened to find persons who had used the internet in the preceding 30 days. The questionnaire gathered demographic data and data about Internet usage.In addition,the interviewer read 17 statement about basic laws and practices related to price discrimination and the targeting of consumers according to their shopping behaviors.

The Evolution Of Racism And Discrimination Essay - 1182 Words

The Evolution of Racism and Discrimination We live in a society where categorization is introduced to us at an early age: when we go grocery shopping, we find fruits labeled at different prices based of their varying origins; when you are introduced to new people, you’ll run into that person who kicks off the conversation by asking what astrological symbol you are. A random question? Not really, as soon as you respond with a â€Å"Gemini† or Capricorn† then you are automatically pigeon-holed into that class of person. â€Å"Oh so you’re outgoing, passionate, and an intelligent person? We’d have great compatibility!† For all they know, you’re a polar opposite of that immediate categorization you’ve just been given based off a symbol, or word, or color. While categories don’t physically harm an individual, it has a detrimental impact on the progression of society as a whole. Categories such as race, class, and gender seemed to be placed into rankings, whether one tends to be dominant than the other. Which opens the door for discrimination and inequalities to be utilized by those in a position of privilege. One could blame our ever-evolving social media and entertainment outlets like Facebook, Instagram, and Snapchat for this process which all subjugate users to some implemented form of ranking/popularity system. But to understand the situation in order to change it, we first need tools that help us interpret how racism and discrimination are planted in our minds and how we act alongShow MoreRelatedThe Evolution Of Racism And Discrimination Essay1381 Words   |  6 PagesAntione Crawford Soc101 Mid-Term Essay The Evolution of Racism and Discrimination We live in a society where categorization is introduced to us at an early age: when we go grocery shopping, we find fruits labeled at different prices based of their varying origins; when you are introduced to new people, you’ll run into that person who kicks off the conversation by asking what astrological symbol you are.
