The Study of the Relationship between the Position of Scapula and the Endurance of Shoulder Girdle Muscles

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 Kiblerʹs 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.
