Research supports foam rolling for improved health and fitness. Self-myofacial release (SMR) has been a buzzword in the fitness industry for about a decade now, and for good reason. An acute bout of SMR on the quadriceps muscles enhances knee-joint rage of motion with a concomitant deficit in muscle performance.
According to one study, SMR is a valuable tool for preparing a competitive or recreational athlete for exercise and offers increased strength and jumping ability.
Finally, foam rolling reduces arterial stiffness and improves vascular endothelial function.Resource: IDEA Fitness
