The acute effects of different durations of static stretching on dynamic balance performance.

摘要

The purpose of the study was to determine and compare the effects of different durations of stretching on balance. Female subjects (n=23) had their balance assessed before and after two stretching interventions and a control condition on three separate days, at least 48 hours apart. The quadriceps, hamstrings, and plantar flexors were stretched after a warm-up and repeated three times. In one stretching protocol, the positions were maintained for 45 seconds, while in the other stretching protocol, the positions were held for 15 seconds. The 15-second condition produced a significant improvement in the OSI scores (p 0.05). However, repeated measures ANOVA revealed no significant differences between groups (p = 0.08). These results suggest a stretching protocol with 45-second hold durations does not adversely affect postural stability when using the current stabilometry testing procedure.
