Background: The peak expiratory flow rate (PEFR) is an important and simple determinant of ventilatory functions. Increased body weight, especially in adolescents, has a negative impact on functional performance. Here an experimental study of the effect of aerobic exercise program on those subjects regarding ventilation and body weight.
Objective: To investigate the effect of aerobic exercise training on PEFR and BMI in overweight adolescents.
Material and Methods: Sixty overweight participants were randomized to 2 groups, experimental and control groups, each group contains 30 subjects. The experimental group participated in 12-week aerobic exercise program. The control group had no plan of exercise during that period of time. PEFR and BMI were recorded before and after 12 weeks of training in both groups.
Results: After 12 weeks of treatment, the PEFR improved by 13% in the experimental group, while no significant change was observed regarding BMI.
Conclusion: This study demonstrated that aerobic training can improve PEFR significantly in overweight adolescents without significant change in BMI over 12 weeks.
