Acute Effect of Static Stretching and Muscle Warming on the Functional Performance of College Volleyball Athletes

March 26, 2016 updated by: Germanna de Medeiros Barbosa, Universidade Federal do Rio Grande do Norte

The purpose of this study is analyze the effects of static stretching and active warm up, isolated and associated, in functional performance of the lower limbs in college volleyball athletes.

Study hypothesis:

H0: The stretching and / or warm up, alone or in combination, do not alter the functional performance of volleyball players.

H1: The stretching and / or warm up, alone or in combination, alter the functional performance of volleyball players.

Detailed Description

This is a cross-over study containing 11 volleyball athletes randomly divided into 5 groups: control (C), warming-up (gAQ), stretching (gAL), warming-up and stretching (gAQAL), stretching and warming-up (gALAQ). All subjects underwent the evaluation measures of functional performance that were conducted pre and post intervention.
