Abstract:
Objective To investigate the effects of aerobic exercises on the pulmonary ventilation function and electrocardiac activity of simple obesity primary school students. Methods 30 simple obesity boy students were recruited for this study. All the subjects participated in a 12-week aerobic training program (40 min/day,4 days/week). Body composition,pulmonary function and electrocardiogram were tested at the beginning and the end of the training program. Results Decreases of fat mass and body fat ratios were found in response to the exercise stimulus (P<0.05). Free-fat mass(FFM) significantly increased. No statistically significant differences of waist hip ratio (WHR) were found. Among the pulmonary ventilation function indexes,MVV、FEV_1、V_(50)/Ht and PEFR increased significantly (P<0.05, P<0.01). Among the EEG indexes,QTd value and QTcd value decreased significantly (P<0.05,P<0.01). Conclusion Aerobic exercises could improve the pulmonary ventilation function of simple obesity primary school students,and had favorable regulations on electrocardiac activity.
