Summary

The aim of this study was to investigate the acute effects of static stretching on the knee joint-position sense of soccer players.

Detailed description

This crossover randomized controlled trial included male soccer players. All participants performed 3 conditions: two experimental conditions, of static stretching of the quadriceps and hamstrings muscles, for 30 or 90 seconds; and a control condition (rest). Knee joint-position sense of the dominant limb was assessed before and immediately after the conditions for the range of 45º of knee flexion by active repositioning, using a video camera. Absolute, relative and variable angular errors were calculated.

Interventions

Type	Name	Description
OTHER	Static Stretching	Static stretching of the quadriceps and hamstrings which was performed in the dominant limb, and held in a position where the participants referred discomfort: * Quadriceps - participants were in the standing position, with one hand holding the back of a chair to maintain the balance, and were instructed to pull the ankle of the lower limb to be stretched, pressing the heel towards the buttocks and, at the same time, extending the thigh; * Hamstrings - participants were also in the standing position, with the heel resting on a chair. They were then instructed to lean the body forward keeping the spine erect and the pelvis in anteversion, to obtain a stretch over the knee and hip.
