Abstract

Objective: To observe the weight reducing effect at different temperatures on obesity patients by doing aerobics. Method: randomly divide 100 obese adolescents into low temperature group, medium-low temperature group, medium temperature group, medium-high temperature group and high temperature group and give them the same aerobic gymnastic training respectively under the following ranges of temperatures: 16~20℃, 21~25℃, 26~30℃, 31~35℃, 36~38℃, and assess the change of their body fat before the training and 24 weeks after the training respectively. Result: after 24 weeks of exercise, the improvement rates of the body fat of the low temperature group (LTG), medium-low temperature group (MLTG), medium temperature group (MTG), medium-high temperature group (MHTG) and high temperature group (HTG) are 5.6%, 7.0%, 11.6%, 16.7% and 22.6% respectively; Patients’ appetite decreases noticeably as the training temperature rises; and the statistical analysis shows that the improvement rate of the body fat of the high temperature group is obvious higher than those of other groups (P < 0.05 or P < 0.01). Conclusion: For obesity patients doing aerobics in 16 to 38℃, as the training temperature rises, their weight can be reduced more remarkably. In the 4 aerobic weeks, lower temperature enhances their appetite, whereas higher temperature represses their appetite.
