Abstract :
Zurkhaneh as one the oldest sport is include many overhead movements. The purpose of this study was comparison between ratio of strength and range of motion in internal and external rotation in the shoulder joint’s zurkhaneh athletes with Non-athletes. The subjects in this study included 29 zurkhaneh athletes’ with mean age (23.51±2.04) and mean years of sport history (8.75±4.47) and 30 non-athletes athletes with mean age (24.8±1.56). Data were collected through questionnaires, and subjectsʹ strength was measured by “Hand-held dynamometer”and ROM was measured by “Leighton flexometer”(r=0.90–0.99) in bothupper extremities. Data were analyzed by paired samples t-test and independent samples t-test. The results of this study showed significant degrees at internal/external rotation ROM ratio of zurkhaneh athletes than the non-athletes group (p?0.05).Same result also was found in strength ratio in internal/externalrotators in this group (p?0.001). Therefore repeated pattern of movements in the zurkhaneh sport at the long time causes imbalance in strength and range of motion shoulder joint that need to corrective exercise. It can be concluded due to specific demands such as repeated rotationalmovements in shoulder joint; they need compensatory corrective exercises.
