Question

I need help answer to forum class discussion:

OBESITY: Share data from a research study showing physical activity intervention that improved body composition in overweight and obese individuals. Share details regarding the "dose" of exercise, including the mode, intensity, duration, etc, as well as how body composition was assessed. Please be sure to include a link to the article, or attach it to your post.

Answer 1

   OBESITY

                         Obesity and its metabolic complications are associated with insufficient physical activity , excessive sedentary time , unhealthy eating behaviuors , these factors also constituting an unheaithy life style. Primary prevention programs, often based on interventions in schools and community based .Promote the positive effects of physical activity and healthy eating behaviours . These interventions targeting the general populations are effective for theprevention of body fat accumulation, and better physical fitness. However , youth with obesity often requires more structured programs.Most studies so far have suggested that increse physical activity level combined with reduced energy intake can improve body composition and health in general in overweight or obese children and adults. Until recently, physical activity interventions were mosty based on edurance exercise combined or not with dietary interventions , and it is only recently that resistance training has gained interest. Edurance exercise , also termed aerobic exercise, refers to exercise performed for extend period of time , at low to moderate intensities and that relies primarily on the aerobic metabolism. Resistance exercise also called strength or weight training or weight lifting , involves muscular strength and mainly consists in isometric , isotonic or isokinetic exercises. Resistant training is designed to develope greater resistant in order to develop muscle strength and anaerobic endurance. Resistance exercise has been long proscribed in children and adolescents and was thought to be at high risk of musculoskeletal injuries or negative effects on the maturation process given the mechanical consraints . In the case of obesity, resistance training was not advised considering that the resulting energy expenditure is low, and would thus have little effects on adiposity . Only recently , number of studies have shown that resistance training can be performed safely and be beneficial to obese youth when cautiously supervised by professional and following established guidelines . Since it is particularly difficult for obese youth to engage physical activity , it is necessary to find exercise prescriptions favoring there adherence , and resistance training may be efficient in this way.

                        the world health organization currently recommend at lest 60 minutes of moderate vigorous physical activity , with exercise that strengthen mucles and bones at least 3 days per week.Structured aerobic exercise programs with sessions 3 to 5 times per week of moderate intencity upto 60 minutes are the commonly implemented weight loss interventions in children and adolescents. Aerobic exercise training is usually proposed to obese youth but an important limitations their poor compliance to this type of exercise .A moderate intencity and progressive resistance exercise are more applicable to youth 10 week programme .

               Body coposition assesed it includes fat , protien water and minerals .it also describes weight more accurately than BMI.
