Foam rolling (FR) is a form of self-myofascial release (SMFR) that has demonstrated efficacy in increasing ankle dorsiflexion; however, few studies have examined the effects of FR on muscle performance. The purpose of this study is to investigate the effects of FR the triceps surae and efficacy of dorsiflexion range of motion (ROM) and functional hop test (FHT) performance in a 18-40 year old recreationally active population. Exclusion criteria include: current upper or lower extremity injury, currently foam rolling the calves, inability to hold a press-up positon for 30 seconds, an answer of "yes" on the physical activity readiness questionnaire, or the inability to perform FR or either FHT. Researchers hypothesize that FR will improve dorsiflexion ROM and FHT performance when compared to a control group. Pre and post-test measurements will be measured to account for the independent variable of time and an independent t-test will be used for comparison between groups.
