About

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

Full 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.

Enrollment: 17 patients

Sex: Male

Ages: 18 to 30 years old

Volunteers: Accepts Healthy Volunteers

• with positive knee integrity tests (anterior drawer, posterior drawer, Lachman test and valgus and varus stress tests)
