Investigation into biomechanical and physiological characteristics of manual resistance training

在这项研究中，比较了手动阻力训练（MRT）与传统重量阻力训练（WRT）的生物力学和生理方面的差异。受试者在两个实验中进行了MRT和WRT的单侧肘关节伸展练习。研究发现，与高负荷WRT相比，MRT为肌肉提供了更高强度的肌肉活动和机械负荷，以及随后的离心诱导肌肉损伤。此外，MRT引起与WRT相当水平的血乳酸和急性激素反应。这两个实验的结果表明，与传统的高负载WRT相比，MRT具有更大程度提高强度的潜力。本研究结果为MRT的实际应用提供了科学依据。

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.
