An Acute Bout Of Self-Myofascial Release In The Form Of Foam Rolling Improves Performance Testing, Corey A. Peacock, Darren D. Krein, Tobin A. Silver, Gabriel J. Sanders, Kyle-Patrick A. Von Carlowitz
International Journal of Exercise Science
International Journal of Exercise Science 7(3) : 202-211, 2014. Recent developments in the strength and conditioning field have shown the incorporation of foam rolling self-myofascial release in adjunct with a dynamic warm-up. This is thought to improve overall training performance; however, minimal research exists supporting this theory. Therefore, determining if an acute bout of foam rolling self-myofascial release in addition to a dynamic warm-up could influence performance is of importance. In order to do so, eleven athletically trained male subjects participated in a two condition, counterbalanced, crossover within-subjects study comparing two particular warm-up routines. The two warm-up routines compared were …
