The effect of attempted ballistic training on the force and speed of movements.
Athletes in sports requiring explosive movements might benefit from a unique form of training in which a limb is restrained while the athlete attempts ballistic (explosive) movements. We investigated the effects of such ballistic training and conventional resistance training on force and speed of front kicks, side kicks, and palm strikes of martial artists. We assigned subjects randomly to an experimental group (n = 13) or a control (normal martial art training) group (n = 9). Conventional resistance training produced a gain of 12% (95% likely limits +/- 13%) in front kick force relative to the control group. Overall ballistic training and conventional resistance training decreased side kick force by 15% (+/-14%), but movement speeds increased by 11-21% (+/-13-17%). Responses to ballistic training were generally more marked in more highly skilled athletes. Attempted ballistic training may be a beneficial adjunct to resistance training for skilled athletes in sports where speed rather than force is critical.
