The factors regulating their secretion and its varied role in controlling psychological approach of a person has been dealt in the study. The article is review of various literatures available on the subject. The results of the paper serve as a solid medical background to the effect of these bio chemicals on health of a person. CNN (2008) Exercise: 7 benefits of regular physical activity. Retrieved November 20, 2008, from http://www.cnn.com/HEALTH/library/HQ/01676.html The article in CNN details the seven integral benefits of regular physical activity. The report covers the general aspects of exercising and its benefits on the body and the mind of a person. It also covers the role of exercising in averting a number of diseases. The general approach of the article provides a broader idea to the reader on the topic. The reliability of the source, the explanatory approach and the simplicity in the language makes it an efficient reference material. Corbin, C. B, Pangrazi, R.P and Frank, B.D. (1990) Definitions: Health Fitness and Physical activity, Research Digest 3(9) This work concludes the positive health impacts of physical exertion on overweight and obese children. While analyzing the ill effects of obesity on the body, the study also suggests the possible changes in life styles so as to fight this problem. It asserts the need of an enjoyable exercising environment so as to have a positive experience out of it. The study covers the psychological aspect of exercising which makes the study unique. Review of several literatures and the analysis of the studied population were done by the authors to attain the results of the study. Magarey,A.M. Daniels, L.A & Boulton, T.J (2001). Prevalence of overweight and obesity in Australian children and adolescents: reassessment of 1985 and 1995 data against new standard international definitions. Medical Journal of Australia.174:561-564 The study tries to analyse the statistics on the increased occurrences of cases of obesity among children and adolescents. It further studies the impact of the lack of physical activity in children and adolescents and asserts that physical activities hold an important role in helping to combat the detrimental heath problems caused due to obesity in the studied population. The work brings out a better picture of the prevalence of over weight and obesity as it compares and reassess the available national data with relevance the standard definitions on Body Mass Index, Obesity and other health related terminologies which has been recognized internationally. Marcelo, B.S. Maria, F.A. Eduardo, R. R. Marcel, C. F, Mirian, U. Lício, A. Velloso, Mario, J.A. and José, B.C. (2006) Exercise Improves Insulin and Leptin Sensitivity in Hypothalamus of Wistar Rats. Diabetes. 55:2554-2561 The role of prolonged exercise has stated to promote a substantial effect on the energy balance of rats by the study. The study provides direct measurements of leptin and insulin signaling in the hypothalamus and documents increased sensitivity to these hormones in the hypothalamus of exercised rats in an IL-6–dependent manner. The strength of the findings of the study is that it provides support for the hypothesis that the appetite-suppressive actions of exercise may be mediated by the hypothalamus. The peculiarity of the methodology in measuring the accurate effects of exercise has provided support to form it as a reference. Melanson, E.L & Freedson, P.S.(1996).Validity of the Computer Science and Applications, Inc activity monitor. Medicine and Science in Sports and Exercise.27:934-940. The study evaluates the relevance of computer science and its applications in evaluating the efficacy of differential levels of exercising. The study concluded that the CSA and Caltrac accelerometers had similar validity and that either instrument can be used to estimate Exercise Efficacy of differential groups. The methodology followed by the study was to use computer based instruments to assess the physical activity during treadmill walking and running at three different grades. These values were compared with the standard model values to evaluate the validity of computer science. Pollock, M. L., Gaesser, G. A., Butcher, J. D., Despres, J., Dishman, R. K., Franklin, B. A., & Garber, C. E. (1998). The recommended quantity and quality of exercise for developing and maintaining cardio respiratory and muscular fitness, and flexibility in healthy adults. Medicine and Science in Sports and Exercise, 30, 975-991. The work studies the combined role of frequency, intensity, and duration of chronic exercises in developing and maintaining cardio respiratory and muscular fitness, and flexibility in healthy adults. The study recommends the quantum of exercising with reference to the participant's needs, goals, and initial abilities. Research has been done on the mode, frequency and different variables which would affect the health of the related population. The strength of the study is its resultant deliverance of a design which aids an individual to provide the proper amount of physical activity to attain maximal benefit at the lowest risk Scully, D., Kremer, J., Meade, M.M., Graham, R., Dudgeon, K. (1998). Physical exercise and psychological well being: a critical review. British Journal of Sports Medicine, 32, 111-120. The paper researches on the relation between physical exercise and psychological health. It has evolved with the result that along with the general advantages of exercise in terms of physical health, there is an equivalent psychological complex relation as well. The paper is extensively based on research evidences focusing on the relation between physical exercise and depression, anxiety, stress responsivity, mood state, self esteem, premenstrual syndrome, and body image. The study has also considered the phenomena of exercise addiction and withdrawal, and implications for exercise prescription. Sriwijitkamol, A et al (2007). Effect of Acute Exercise on AMPK Signaling in Skeletal Muscle of Subjects With Type 2 Diabetes. Diabetes.56.836-848 This research has studied in detail the activation of AMP-activated protein kinase (AMPK) by exercise and the same has been stated to induce several cellular processes in muscles. The research has found that these processes have active role in regulating blood sugar level to a major extend. The study had included extensive experiments in the lab conditions to study the role of exercise. Medical methodologies followed in the research strengthen the scientific background of the research. Toth, P.P. (2005). The Good Cholesterol: High Density Lipoprotein. American Heart Association.111. e89-e91. The positive effects of High Density Lipoprotein and its multiple effects on the cardiovascular system have been studied by this research. An amendment of life style and continued medication resulting in the raise of High Density Lipoprotein is stated to help the aversion of cardiovascular complications. The work is a compilation of information available on the effects of High Density Lipoprotein on the cardiovascular system. The fact that wide rage of information was reviewed to formulate this paper increases its reliability as an effective reference. Read More
