RESUMO
OBJECTIVE: To examine the acute effects of self-myofascial release (SMR), static stretching (SS), and the combination of self-myofascial release and static stretching (SMR + SS) on glenohumeral internal rotation range of motion (GH IR ROM) in overhead athletes with glenohumeral internal rotation deficit (GIRD). PARTICIPANTS: Twelve asymptomatic adult male amateur softball position players exhibiting GIRD. RESULTS: All three methods significantly improved GH IR ROM. Post hoc testing revealed that SS alone and SMR + SS improved GH IR ROM significantly more than SMR alone. However, there were no significant differences in GH IR ROM between SS alone and SMR + SS. CONCLUSIONS: If an athlete has a limited time to perform a warm-up (e.g., 3-4 min), SS alone is recommended to improve GH IR ROM. However, if the athlete has more time available to warm up (e.g., 7-8 min), combining SMR + SS may result in a greater increase in GH IR ROM.
