| Research Abstract |
In this study, biomechanical and physiological aspects of the manual resistance training (MRT) were compared with those of the traditional weight resistance training (WRT). Subjects performed unilateral elbow extension exercises of MRT and WRT in the total of two experiments. It was found that MRT provides muscles with higher-intensity of muscle activity and mechanical load, and subsequent eccentric-induced muscle damage than high-load WRT. Besides, MRT elicits comparable levels of blood lactate and acute hormonal responses with WRT. The results of the two experiments suggest that MRT has a potential for improving greater degrees of strength than the traditional high-load WRT. The outcome of this study provide a scientific basis for the practical applicability of MRT.
