Purpose: This study investigated the effects of massage at two different hamstring positions on hip flexion angle (HFA) in healthy adult males. Methods: Thirty-two healthy adult males were randomly categorized into one of the following three groups: the group being massaged at the musculotendinous junction of the hamstrings (n = 11); the group being massaged at the muscle belly of the hamstrings (n = 11); and a control group being massaged at the muscle belly of the contralateral hamstrings (n = 10). Massage was performed for 3 minutes with the same pressure in all the three groups. HFA values was assessed by blinded raters before massage; immediately after massage; and 3, 6, 9, and 15 minutes after massage. Results: HFA value in the group being massaged at the musculotendinous junction of the hamstrings was significantly greater than that of the control group immediately after massage and 3 and 6 minutes after massage. Conclusion: These results suggest that massage at the musculotendinous junction of the hamstrings can induce greater HFA.
