The Effect of 4 Weeks Aerobic Training With Chest Wall Movement Restricting on Aerobic Power and Cardio-Respiratory Functions in Healthy Subjeets

This study aimed to evaluate the effect of 4 weeks aerobic training with chest wall movement restricting on aerobic power and cardiorespiratory functions in healthy subjects. Eighteen untrained male students were volunteered to participate in this study and divided in two experimental groups (El and E2). They accomplished aerobic training with 70- 85% of HRmax for 4 weeks, 3 session per week. El performed aerobic training with elastic strap on chest wall but E2 performed aerobic training solely. To analyze data, student t test was used. The results showed that V02max, MVV and VEmax of two group increased and an increment in TTE of El was observed (P<0.05). Also El had greater increase in V02max (P=0.001), MVV (P=0.008), VEmax (P=0.04) compared to E2. NO significant change observed in FVC and FEVi/FVC in both groups (P>0.05). Therefore, the results showed that both groups had an significant increment in this short duration in aerobic power and cardio-respiratory functions, but El had a greater increase compared to E2.
