Effect of the nature recovery active (at different intensities 20%, 30%,50%) and passive on repeated sprint ability (RSA) of football players U19

Abstract

This study aims to know the impact of the Active (at different intensities 20%, 30%, 50% of vma) and passive in order to develop repeated sprint ability (RSA) of football players U19, the results obtained. The study concluded that there is a positive impact of the group using recovery active, it’s better than the group using passive to develop sprint ability (RSA). And they found that grope within intensities 30% is super improvement.
