Methods: Forty-six elementary school senior badminton players were examined on their forehand smash speeds using Radar Gun and the Biodex S4 at 240°/s was set to measure the isokinetic strength of the shoulder flexion / extension, elbow flexion / extension, and wrist flexion / extension. The Pearson''s Product-moment was used to analyze the correlation between the average peak torque of the shoulder, elbow, as well as wrist joint and the speed of smash. Results: The average peak torque (PT) of the shoulder flexion, elbow flexion, elbow extension, and wrist flexion are significantly correlated with the forehand smash speed (p< .05). Conclusions: The results of this present research indicated that the forehand smash speed of the badminton players is positively influenced by the shoulder flexion, elbow flexion, elbow extension, and wrist flexion. The study also provides coaches with the consultation on the smash training mode.
