The relation between isokinetic strength, shoulder mobility and ball velocity at elite male volleyball players

Abstract

The working group of the current study which aims at investigating the relation of isokinetic strength, shoulder mobility and ball velocity at elite male volleyball players was made up of 20 male volleyball team players having the age, body weight and height means; 28,40±3,32 age, 83,25±7,80 kg, 192,54±4,20 cm and volunteering in the study. The data obtained in the study was analysed in the package program of SPSS (Statistical Package for Social Sciences) for Windows 22.0. For all variables in the study, Pearson correlation test was applied. In the research, 60°/sec. dominant and non-dominant, internal and external isokinetic strength values (nm) were found as 70,07±6,20, 66,57±6,12, 40,57±7,90, 39,23±8,49, respectively. Dominant internal rotation values of the players were found as 60,18°±7,58, dominant external rotation values were found as 105,00°±8,47, non-dominant internal rotation values were found as 56,00°±4,07, non-dominant external rotation values were found as 100,71°±8,70. Service speed (km/h) was 70,55±3,66. As a conclusion, upon the investigation of the correlation values between isokinetic strength, shoulder joint mobility and ball velocity at elite male volleyball players, a statistically direct relation was not found between them at the level of α=0.05 significance.
