Current study aims to compare the strength of shoulder’s complex muscles between elite female volleyball players with regard to the scapula positioning. Methods: Twenty four elite female volleyball players who were selected randomly ( ranging from 20 to 30 years old ) and 5 years' experience of premier league, after matching considering hight, weight and shoulders width, divided into two groups consisted of athletes with retracted scapula and protracted scapula. Those with 16 to 18 cm scapular distance categorized as retracted scapula subjects and those with higher than 18 cm classified as subjects of protracted scapula. The lateral scapula slide test (LSST) method was applied to determine scapular positioning, and the performance of shoulder complex muscle strength was examined using an isometric myometer (MIE). Descriptive statistics were implemented and a normal distribution was confirmed. Student's paired t-test and independent t-test were used to assess the differences between the two groups and between dominant and non-dominant sides (p SP - 97 EP - 107 AD - KW - Strength KW - Shoulder complex KW - Elite KW - Position of scapula UR - http://rjms.iums.ac.ir/article-1-3944-en.html ER -
