研究概览
简要总结
An open-label, single-group, control, pretest-posttest clinical trial is going to be conducted, with 16 healthy sprinters. Rectus femoris length and hamstring strength and electromyography is going to be assessed at baseline, after 10 minutes control and after an static rectus femoris stretching technique.
The main objective is to register if an increase in rectus femoris stretching Range of Motion, increases hamstring strength and activity due to their antagonic relationship and their relation with pelvic tilt.
