Kinematics analysis of dominant and non-dominant lower limb during step and jump forward lunge in badminton

Abstract

This study was conducted to determine and compare the kinematics during step forward lunge (SFL) and jump forward lunge (JFL) in badminton. Fifteen university badminton players (mean age = 22.07 ± 1.39 years old) were recruited and were assigned to perform SFL and JFL while holding a badminton racquet using their dominant hand. Results showed that ascend time, descend time and time taken were significantly faster and the step distance was significantly greater in the dominant limb compared to the non-dominant limb during both SFL and JFL. To conclude, it is important for the coaches and athletes to reduce the performance asymmetries in order to enhance their performance in the court besides can decrease the risks of injury that might occur as a result of overuse of the dominant side.
