Background and Aims: The overhead throwing is a complex motor pattern, and limitation in the ROM of hip and shoulder joints can have a negative effect on the performance of this skill and lead to injury in this joint. The purpose of the present study was to compare the ROM of the hip and shoulder joints in elite handball players with and without shoulder injury.
Materials and Methods: Totally, 60 professional handball players from the Iranian Premier League were purposefully selected and divided into two groups: 27 players of the first-line (Center and Back) and 33 players of the second-line (pivots, wings) were studied. The ROM of shoulder internal/external rotation and hip extension/internal rotation, as the variables, were measured using a goniometer at the beginning of the season. Also, shoulder injuries were recorded during the Premier League season. The Kolmogorov-Smirnov test was used to examine the normality of the data and independent t-test was used to compare the ROM of hip and shoulder joints in players with and without shoulder injuries at a significance level of P Results: According to the findings of current study, players in the first-line with shoulder injuries demonstrated increased external rotation and limited internal rotation in shoulder joint compared to players without shoulder injuries. Also, there was a significant difference between the ROM of the internal rotation of the shoulder joint in the dominant hand with non-dominant hand in the first-line players with shoulder injuries. There was also a significant difference between the ROM of hip extension in the dominant limb and also ROM in internal rotation of the hip joint in the first-line players with shoulder injury.
Conclusion: Based on the results of the current study, decrease of the internal rotation in the shoulder joint in dominant hand, the increase of external rotation in the shoulder joint in non-dominant hand, limitation of the hip extension in dominant limb and internal rotation in the non- dominant limb, and also difference in ROM of internal rotation in shoulder joints in both dominant and non-dominant hands can be a risk factor in the incidence of shoulder injuries in handball players.
