Clinical Trial Summary

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.

Intervention

Procedure:
• Rectus femoris stretching
Patient lying prone with the non-implicated leg outside the treatment table resting on the floor. Physical therapist flexes patients knee until tension is felt. In that position 5 seconds' isometric contraction is asked and physical therapist progresses in knee flexion range of motion until new tension is felt. After three contract-relax procedures physical therapist holds the range of motion for 30 seconds.
