International Journal of Exercise Science 12(1): 950-959, 2019. Following anterior cruciate ligament reconstruction, individuals experience inadequate functioning of the quadriceps and decreased muscular strength. Decreased function delays return to physical activity and increases potential for re-injury. While several squat variations exist, a new variation has emerged in rehabilitation. The purpose of this study was to compare muscle activation of the Vastus Lateralis (VL), Vastus Medialis (VM), Rectus Femoris (RF), Gluteus Maximus (GM), and anterior posterior center of pressure (AP displacement) alterations during a single leg squat variation (SLS variation) versus a traditional split squat using electromyography (EMG) in healthy active …

International Journal of Exercise Science 12(3): 839-846, 2019. Self-myofascial release (SMR) is an alternative therapy believed to increase myofascial mobility by exciting muscles and increasing blood flow to the treated area. Previous literature suggest SMR produces conflicting results on performance, muscle activation, range of motion (ROM), and recovery. This study was designed to utilize SMR on a fatigued individual prior to exercise and measure its’ effects on muscle activation, ROM, and perceived recovery compared to a dynamic warm-up session. The findings could help develop an efficient warm-up protocol for resistance-trained individuals. Electromyography (EMG) measured muscle activation of the rectus femoris …
