Interval Training with Blood Flow Restriction on Aerobic Performance among Young Soccer Players at Transition Phase

The purpose of current study is investigating effect of Blood Flow Restriction Interval Training on aerobic performance among young football players during transition phase of periodization. Twenty eight young male football players were recruited in this study. Subjects were randomly divided into three groups: control, Normal Interval without Kaatsu, and Interval with Kaatsu. Exercise protocol was based on aerobic interval at 400 meters with maximum effort for 3 sets in per sessions (First week) and 4 set (Second week). The results shown that there is a significant difference in aerobic power between groups p<0.05. Post hoc comparisons indicated that the mean of aerobic power was significantly different between all three groups. It has been shown, there is a signifi cant difference in rate of perceived exertion between groups at the p<0.05. Post hoc comparisons indicated that the mean of RPE was significantly different between groups. Th is study has been shown that aerobic power and RPE was improved by both normal and BFR interval method. We also found that there is not significantly difference in NIWK and IWK group at rate of perceived exertion. Th is results may be explained by reducing intensity of exercise by subjects during exercise with BFR in cause of pain in their legs during exercise. The result of current study suggest that Intermediate-intensity, interval training with BFR improves aerobic capacity and RPE concurrently in young football players and prevent decline of VO2max at result of retraining at transition phase.
