Muscle Energy Technique versus PNF: effectiveness on hamstring muscle stretching

Although PNF´s Contract-Relax with Antagonist Contraction (CRAC) and Muscle Energy Techniques (MET) increase muscle flexibility and Range of Motion (ROM), few studies compared their effectiveness. They share several features but one major difference, the intensity of muscle contraction prior to stretch, perceived maximum in CRAC, and a percentage of the perceived maximum in the MET. Confirm if CRAC and MET are effective in stretching the hamstring muscle in the short term, if both are determine the most effective. ; info:eu-repo/semantics/publishedVersion
