Not Applicable

Completed

• Conditions: Healthy

• Registration Number: NCT06226974
• Lead Sponsor: University Fernando Pessoa

Brief Summary

The purpose of the study is to investigate the acute effects of static stretching on the shoulder joint position sense of overhead athletes.

Detailed Description

A crossover randomized controlled trial will be conducted with 17 overhead athletes (9 males and 8 females). All of them will perform the 3 study conditions in random order: a control (5-minute rest), and static stretching of 30 or 90 seconds of muscles around the shoulder. The shoulder joint position sense will be assessed before and immediately after these conditions, and tested by active repositioning for the range of 110º of flexion, with a video camera. Absolute, relative and variable angular errors will be calculated.

Primary Outcome Measures

Name	Time	Method
Variable angular error	Change from Baseline (Before) to Immediately after interventions or control (After)	The standard deviation of the 3 repositionings
Absolute angular error	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	Change from Baseline (Before) to Immediately after interventions or control (After)	The arithmetic difference between the target range and the range achieved
