Nineteen subjects were randomly assigned to either the wrist training group (n=9) or the control group (n=10). The training group performed wrist exercises in six directions (flexion, extension, pronation, supination, radial deviation, and ulnar deviation) while the control group did not. Data were collected on the isometric torque control, one-repetition maximum (1-RM) strength, and isokinetic maximum torque (angular velocity of 60[degrees]/s wrist movements) before and after six weeks of resistance training and at two-week intervals during training. The training group showed significant decreases in isometric torque control error in all six directions after 2 weeks of resistance training, while the control group did not show significant increase or decrease. After 4 weeks of training, the training group showed significant increases in maximum strength in all six directions as assessed by 1-RM strength and isokinetic strength tests, while the control group did not show any statistically significant changes. This study shows that motor control significantly improves within the first two weeks of resistance training, while the wrist strength significantly improves within the first four weeks of resistance training. Based on the findings of this study, coaches and trainers should consider wrist resistance training to improve athletes' muscular strength and control of the wrist muscles.
