The main purpose of this study is to analyze whether there is a difference between dominant and non-dominant biceps anddeltoid muscle volumes of badminton players.Also hand grip strengthlevels were compared dominant and non-dominanthands of badminton players.14 registered badminton players between the ages of 11 and 14, who have been playing badmintonfor at least 5 years and practicing at least 5 days a week, have participated in this study. The muscle volumes of the participantswere determined through an MR (1.5 T Philips Achieva Netherlands) device. The T1 weighed MR images of 5 mm sectionthickness of dominant and non-dominant deltoid and biceps muscle volumes of the participants were obtained, and the lineswere drawn at each section at the work station of the related muscle and the sectional area was calculated. The muscle volumewas obtained by multiplying the resulting sectional area by the section thickness (Cavalieri principle). Wilcoxon signed ranktest was used to analyze the data obtained in this study.It was observed that the dominant deltoid muscle volumes of theplayers were more than their non-dominant muscle volumes (p<0.01). Dominant and non-dominant biceps muscle volumes ofthe players were analyzed and it was observed that the dominant biceps muscle volumes of the players were more than theirnon-dominant biceps muscle volumes (p<0.01).Dominant hand grip strength values were found to be higher than nondominant hand (p<0.01).It was consequently observed that the dominant biceps and deltoid muscle volumes and the dominantgrip strength values were higher of badminton players than non-dominant side.These results suggest that the badmintonplayers should also focus on exercises for improving the non-dominant side of their bodies.Otherwise, it can lead to muscleimbalance and injury.
