Introduction

The hamstring muscles are subject to acute injuries in many sports, with the severity of a second injury upon return being much worse than the first. Training the hamstrings eccentrically can develop the strength and size as well as change the optimal length and stiffness of the muscle. The posterior thigh consists of the long and short head of the biceps femoris, the semimembranosus, and the semitendinosus, with each muscle having a specific function and putting emphasis on how to properly introduce rehabilitation after injury as well as creation of strength programs. In order to view the soft tissue activation during exercise along with muscle damage after exercise, functional magnetic resonance imaging (fMRI) can be used as a noninvasive way to further understand what electromyography cannot. To take it a step further, short tau inversion recovery (STIR) shows the tissue differences in w…
