Purpose: The purpose of this study was to determine the effect of foam rolling on hamstrings flexibility, isometric and isokinetic torque. Participants: Thirteen female participants (N = 13; age: 28.5 + 6.8 years of age; height: 165.5 + 6.7 cm; mass: 64.2 + 8.4 kg) volunteered to participate in the study.
Methods: Hamstring flexibility was assessed using a sit and reach test; muscle strength was assessed by having participants complete a maximal voluntary isometric contraction (MVIC) of the hamstrings and maximal effort isokinetic knee flexion test using an isokinetic dynamometer. Participants completed these tests prior to any intervention (pre-rolling 1), after sitting quietly for 3 minutes (pre-rolling 2), and after completing a bout of foam rolling (post-rolling). Foam rolling was performed for two one-minute sets, with one minute rest in between. Each dependent variable (flexibility, MVIC, peak isokinetic torque) was assessed using a repeated measures analysis of variance with Time (i.e., pre-rolling 1, pre-rolling 2, post-rolling) as the independent variable. A Bonferroni post-hoc was used when there was a significant omnibus F-ratio.
Results: Flexibility was different across tests (p<0.05) with flexibility during post being greater than pre-rolling 2 (p<0.05). Average isometric torque was not influenced by Time (p = 0.356). Peak isokinetic torque was not influenced by Time (p = 0.958).
Conclusions and Recommendations: Hamstring flexibility was greater following a single bout of foam rolling without negatively influencing isometric or isokinetic maximum voluntary contraction.
