The objective of the present study was to compare the range of motion (ROM) of shoulder joint in movements (inward and outward rotation, abduction and extension) in active and former weightlifters, and ordinary people (non-weightlifters). Methods: For this purpose, 61 men aged 19-29 years from Golestan and Markazi provinces were selected using cluster random sampling and categorized in three groups, that is, active weightlifters (N.=23), former weightlifters (N.=18) and non-weightlifters (N.=20) who, then, participated in a causal-comparative study. Measurements were conducted using Universal goniometer as suggested in Norkin and White’s method (1995). Data analysis was carried out using paired t-test, ANOVA and LSD. Results: ROM of shoulder joint in active and former weightlifters was significantly less than in non-weightlifters (P<0.05). There were no significant differences between ROM of shoulder joint in active and former weightlifters (P<0.05). Conclusion: It could be concluded that ROM decrease among the weightlifters after they retire from this field might be expected.
