Your IP: Furthermore, the study portrays about ACL injury, which is more common due to alteration in muscular co-activation, & further research is required to identify the efficacy of foam rolling on activation of muscle around the knee joint. Activities or exercises which have the potential to worsen the injury need to be avoided. The short head extends up the thigh and joins with a muscle known as the gluteus maximus or glutes for short. It originates in two places: the ischium (lower, rear portion of the pelvis, or hipbone) and the back of the femur (thighbone).
