University of Southern Mississippi
Self Myofascial Release: Effects On Hamstring Range Of Motion And Torque, Dillion F. Evans
Honors Theses
Research has indicated that static stretching may reduce force production capabilities. This has led many practitioners to exchange static stretching for alternative methods of increasing range of motion (ROM) in warm-ups. Despite having little research to support its use, self myofascial release—foam rolling—has been suggested as a viable alternative (Macdonald et al, 2013). The objective of this study was to determine how self myofascial release (SMR) of the hamstring muscle group affects ROM and torque production capabilities of the hamstring muscle group. Ten subjects (age 26.5 6.5 years, mass 74.412.1 kg, height 1738 cm) were recruited. A within subjects randomized, …
