Overview
Brief Summary
The aim of this study isto investigate the influence of acute static stretching on the ankle joint position sense of soccer players.
Detailed Description
This crossover randomized controlled trial will include semi-professional soccer players. All participants will perform 3 conditions: two experimental conditions, of static stretching of the gastrocnemius and tibialis anterior muscles, for 30 seconds or 90 seconds; and a control condition (rest). Ankle joint position sense of the dominant limb will be assessed before and immediately after the conditions for the range of 20º of plantar flexion by active repositioning, and using a video camera. Absolute, relative and variable angular errors will be calculated.

Outcomes
Primary Outcomes
Variable angular error
Time Frame: Change from Baseline (Before) to Immediately after interventions or control (After)
The standard deviation of the 3 repositionings
Absolute angular error
Time Frame: Change from Baseline (Before) to Immediately after interventions or control (After)
The absolute value of the difference between the target range and the achieved range
Relative angular error
Time Frame: Change from Baseline (Before) to Immediately after interventions or control (After)
The arithmetic difference between the target range and the range achieved
