Effectsof4WeekAerobicExerciseonPhysiqueofObeseAdolescents

Objective To investigate the effects of a 4-week weight reduction exercise on body morphology, physical function and physical fitness of obese adolescents. Methods 48 obese adolescents(28 males, 20 females)taking part in the Summer Sports Camp were selected as the research subjects to measure their body morphology indicators, body function indicators and body quality indicators. An individualized sports scheme was then designed for each research subject. And four weeks later, the measurement of the three types of indices was repeated and the results of both times were compared. Results The indices in terms of the body morphology and body function decrease significantly after the four week sports scheme; the indices in terms of the body quality are remarkably improved in aspects like the lower limbs explosive force, the right hand gripping power, the sitting trunk forward bending, one leg standing with closed eyes. Conclusions 4-week aerobic exercise with low and moderate intensity can effectively reduce the body fat in obese adolescents. It not only brings down body weight, body fat percentage and body circumference, but also improves the function of cardiovascular system and the physical fitness, so it has obvious effect on promoting obese adolescents’ health.
