The goal of this clinical trial is to evaluate the effects of capacitive resistive electric transference (CRET), which is frequently used in clinics and sports clubs for professional soccer players with hamstring injuries. The main questions it aims to answer are: Return to sports time Treatments sessions number Muscle oxygen saturation The investigators will administer the treatment to a experimental group to see if CRET therapy is effective. The investigators will also administer a standard rehabilitation program to both the control and experimental groups. Participants will: Come for treatment and evaluations 3 times a week until participants meet the criteria for returning to sports.
