Four equated groups of five subjects trained using static, dynamic, combination static-dynamic, and control procedures to compare effects on strength of the flexors of the dominant wrist. The static and dynamic groups each performed six bouts of three repetitions daily for 5 weeks. The combination group completed three bouts each of static and dynamic training. Maximum dynamic strength and maximum static strength at three angles were recorded prior to and at termination of training. No significant differences were found among experimental groups in developing static strength of the dominant wrist flexors. However, the combination group made significant improvement (p<.01) over the static group for dynamic strength measurement. Compared with the control group, all experimental groups improved significantly in one or more specific strength tests.
