Överskrift Effect of acute static stretching on force, balance, reaction time, and movement time
Beskrivning Purpose: The purpose of the study was to investigate the effect of an acute bout of lower limb static stretching on balance, proprioception, reaction, and movement time. Methods: Sixteen subjects were tested before and after both a static stretching of the quadriceps, hamstrings, and plantar flexors or a similar duration control condition. The stretching protocol involved a 5-min cycle warm-up followed by three stretches to the point of discomfort of 45 s each with 15-s rest periods for each muscle group. Measurements included maximal voluntary isometric contraction (MVC) force of the leg extensors, static balance using a computerized wobble board, reaction and movement time of the dominant lower limb, and the ability to match 30 % and 50 % MVC forces with and without visual feedback. Results: There were no significant differences in the decrease in MVC between the stretch and control conditions or in the ability to match submaximal forces. However, there was a significant (P < 0.009) decrease in balance scores with the stretch (down arrow 9.2 %) compared with the control (up arrow 17.3 %) condition. Similarly, decreases in reaction (5.8 %) and movement (5.7 %) time with the control condition differed significantly (P < 0.01) from the stretch-induced increases of 4.0 % and 1.9 %, respectively. Conclusion: In conclusion, it appears that an acute bout of stretching impaired the warm-up effect achieved under control conditions with balance and reaction/movement time.
