Stretching to Improve Jumping Performance

University of Saskatchewan40 enrolled

Overview

The study involves comparison of an 8-week plantar flexor stretching program to a shoulder stretching program for improving vertical jump performance in adolescent athletes.

Increasing flexibility may improve vertical jump performance. For example, being able to go deeper into a squat before jumping may allow for greater force development through the range of movement and this may transfer to greater vertical jump height. The study compares plantar flexor stretching to shoulder stretching for improving vertical jump performance in adolescent athletes. Athletes are being stratified by sex and maturity status (before or after estimated age at peak height velocity) and randomized to one of two groups: Plantar flexor stretching (2 sets of 6 stretches, 5 times per week) or the same volume of shoulder stretching. Before and after training, participants are being assessed for vertical jump and landing performance.
