Relationships between Racket Arm Joint Moments and Racket Head Speed during the Badminton Jump Smash Performed by Elite Male Malaysian Players

Three-dimensional position data of nineteen elite male Malaysian badminton players performing a series maximal jump smashes were collected using motion capture system. A ‘resultant moments’ inverse dynamics analysis was performed on the racket arm joints (shoulder, elbow and wrist). Relationships between head speed peak joint moments quantified correlational analyses, inclusive Benjamini–Hochberg correction for multiple-hypothesis testing. The centre at racket–shuttlecock contact was, average, 61.2 m/s with 68.5 which equated to average shuttlecock speeds 95.2 105.0 m/s. revealed that larger shoulder internal rotation moment (r = 0.737), backwards plane elevation 0.614) wrist extension −0.564) associated greater contact. Coaches should consider strengthening musculature rotation, extension. This work provides unique during smash by an population highlights significant relationships resultant moments.
