Relation Between Rectus Femoris Muscle Tension and Hamstring Strength and Activity in Healthy Sprinters

Not Applicable
Conditions
Muscle Stretching Exercise
Interventions
Procedure: Rectus femoris stretching
Registration Number
NCT04344691
Lead Sponsor
Universidad de Zaragoza
Brief 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.
