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 subjects' strength was measured by “Hand-held dynamometer” and ROM was measured by “Leighton flexometer”(r=0.90–0.99) in both upper 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). some result also was found in strength ratio in internal/external rotators 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 included due to specific demands such as repeated rotational movements in shoulder joint, they need a compensatory corrective exercises.
