Studies have conflicting research based on whether foam rolling shows a significant difference in flexibility with the lower extremities. PURPOSE: To determine if there will be a significant difference in flexibility when using a foam roller compared to a five minute walk. METHODS: On the initial visit 14 participants self-reported their age, weight, and height, and then had their baseline flexibility assessed. Treatment conditions consisted of: 1) using a foam roller on the hamstrings, quadriceps, calves, and lower back, and 2) walking on a treadmill for five minutes. After each session, participant’s flexibility was measured three times with the Sit and Reach test. SPSS(V23) was used to conduct a repeated measures ANOVA to explore the difference in flexibility between the trials. The alpha was set at .05. RESULTS: A Repeated Measures ANOVA indicated a significant difference existed among the three levels of flexibility, F(2, 14) = 15.6, p = .001. Pairwise comparisons indicate a significant increase in flexibility after foam rolling compared to walking (+2.29 cm, p = .003) and baseline (+3.81 cm, p = .001). CONCLUSION: This study suggests that foam rolling is a better means to acutely increase flexibility compared to walking, therefore the predicted hypothesis that there will be a significant difference in lower body flexibility when using foam rolling compared to a five minute walk was accepted.
