Effect of Active Isolated Stretching and Static Stretching on Vertical Jump Performance and Flexibility

Abstract

The purpose of this study is to evaluate the effect of AIS compared to static stretching on countermovement jump height production. Currently, only a few studies have conducted research on AIS and CMJ. None of which compared the differences in power production between static stretching and AIS. Most studies show 30 or 60-second holds per muscle group for static stretching. This study will utilize a static stretching and AIS protocol of 45 second hold per muscle group for a total stretch volume of 6 minutes, which meets the American College of Sports Medicine guidelines (ACSM, 2018).
