ACUTE EFFECT OF QUADRICEPS STRETCHING ON PERFORMANCE AND MOVEMENT TECHNIQUE DURING SQUAT JUMPS

Abstract

The aim of this study was to analyze the acute effects of stretching on jumping performance (vertical velocity of the center of mass), vertical ground reaction force (peak force, rate of force development and impulse) and movement technique (joint angles and angular velocities) during the squat jump (SJ). Thirty male individuals performed the SJ test before and after one quadriceps stretching session. This session consisted of four 20-second repetitions of passive static stretching of quadriceps. The results indicated no significant difference in the performance, vertical ground reaction force or movement technique.
