The purpose of this study is to examine the relationship between the position of scapula and the endurance of shoulder girdle muscles. The statistical sample includes 50 healthy 11 - year - old male students selected non-randomly. They were divided into two groups. The first group had excessive scapula retraction (N:
25, height: 144.32 ±4.58, weight: 39.24±6.32). The second group had excessive protraction (N: 25, height: 145.78±3.91), weight: 41.44 ±4. 75). Their endurance and weakness of the shoulder girdle muscles were measured using modified pull-up (AAHPERD) and Kibler’s Lateral Scapula Slide Test (LSST).
The data were subjected to analysis of correlation and t - student test by spss software (version 11). It was concluded that there is a significant correlation between the position of scapula and the endurance of shoulder girdle muscles (P< 0.01, r = -0.43). It was shown that the students with excessive scapula retraction had more shoulder girdle muscle endurance (p <0.05). LSST demonstrated an increase in shoulder girdle endurance in excessive retraction scapula group, but there was not significant difference in both groups.
