Study On The Effect Of Weight Reduction By Exercise On Obese Adolescent’body Constitution,Adiponectin,Irisin

Purpose: Currently, obesity has become a common phenomenon, adolescent obesity is also increasing,it has serious influence to people’s quality of life and health level. This paper studies the four-week summer training obese adolescents to lose weight, measuring the weight loss in before and after physical training, form, function, composition and adiponectin and Irisin in the blood. In this paper,I will analysis in-depth of these data, explore the obese adolescents in weight loss before and after the training in all aspects of the body change, looking for a means of more scientific and effective way to lose weight. As to provide theoretical basis for fully enclosed camp training, in order to better and more effectively promote the obese adolescents who have weight loss, improve physical health, improve the quality of life.Methods: In this study, 50 participated in Wuhan Institute of Physical Education HAOQIAN summer camp weight loss in obese adolescents lose weight training all closed for the study, its four-week aerobic exercise combined with weight training diet intervention. Body composition was measured mention shape, quality, performance, body and serum adiponectin and Irisin other indicators before and after weight training, and in-depth analysis to explore the changes in the index before and after weight training, research and Exercise weight loss diet for obese adolescents constitution health, serum adiponectin variants and Irisin change.Results: Aerobic exercise to lose weight, obesity, adolescent body shape, function, quality of body composition, serum adiponectin, the indexes of Irisin compared with the weight before the change results.(1) The body shape indicators: weight, BMI, waist circumference, hip circumference, waist hip ratio, thigh, calf circumference, circumference of upper arm, forearm circumference indicators generally decreased significantly, the difference was significant(P<0.01). One of the indicators of boys showed a very significant difference(P<0.01); female calf circumference showed significant difference(P<0.05), forearm circumference did not show significant difference(P>0.05), the other indexes showed a very significant difference(P<0.01); each index declined more than girls boys.(2) The physical quality index: boys back strength, grip strength increase was significant difference(P>0.05), body anteflexion in sitting position value increased showed a significant difference(P<0.01), choice reaction time decreased showed significant difference(P<0.05); girls grip strength, vertical jump, body anteflexion raised with significant difference(P>0.05), choice reaction time showed very significant difference(P<0.01).(3) Physical function index: step index, vital capacity index was significantly increased in a very significant difference(P<0.01), vital capacity level of ascension but did not showed significant difference(P>0.05), the total energy consumption and basal metabolic rate decline was significant difference(P>0.05).(4) Body composition indicators: men and women fat percentage, body fat mass, fat soft weight, visceral fat content, subcutaneous fat, left and right upper extremity and trunk ministries fat content decreased significantly, except there are significant differences between boy outside the subcutaneous fat(P<0.05), the other indexes showed very significant difference(P<0.01). In all the above indicators, the boys are higher than girls in variation amplitude.(5) The blood index: serum adiponectin decreased showed a significant difference(P<0.01), the Irisin value decreased significantly difference(P<0.05); unit body fat adiponectin values rise showed a significant difference(P<0.01), the unit body fat increased the Irisin had no significant difference.Conclusion:(1) After weight loss in obese adolescents, body shape, quality, function and other aspects were significantly improved, the degree of obesity is significantly reduced, the various parts of the body the effect reducing weight is balanced, produced a significant effect reducing weight. Multiple index variation amplitude of boys than girls.(2) Obese adolescents lose weight, body fat percentage, body fat, visceral fat content, subcutaneous fat, left and right upper extremity and trunk ministries fat content were significantly decreased, reaching the effect reducing weight is good; to fat soft weight also significantly reduced, will affect the increase in obesity physique, weight in motion increase the strength training or further study, in order to maintain or increase lean body mass.(3) Obese adolescents lose weight, serum adiponectin was significantly decreased, probably because of reduced with the degree of obesity, control fat metabolism adiponectin also reduced or due to reduce the amount of fat and the secretion of adiponectin reduced. Because the body fat weight loss decreased significantly than before, which makes the unit body fat were significantly elevated serum adiponectin(4) After weight loss in obese adolescents, serum Irisin decreased significantly, and weight loss rate related changes may, fat free weight etc., need further study; unit body fat increased Irisin, but has no significant difference.
