摘要
迟发性肌肉酸痛可因乳酸累积、肌肉受伤及韧带拉伤而引起。把15位3年级学生分成3组为研究对象，在离心收缩式运动前分别实施伸展操及热身运动，再以离心收缩式运动诱发迟发性肌肉酸痛，并用High氏肌肉酸痛量表探讨辅助运动是否有助于减轻离心式运动所造成的迟发性肌肉酸痛。同时检查运动前后各种肌细胞内酶（如AST，LDH，CPK）释放的情形，以评估离心收缩式运动造成的肌肉伤害的程度以及肌肉伤害是否因运动前的辅助运动而减轻，同时还检查了血中乳酸和迟发性肌肉酸痛的关系及不同的辅助运动对运动后血中乳酸浓度的影响。
Delayed on-set muscu1ar soreness may be caused by lactate acumulation, muscle injury and ligament strain. The objects of the study were 15 third-grade pupils divided into 3 groups. They did stretching and warm-up exercises before eccentric contraction exercises. The eccentric contraction exercises induced delayed on-set muscular soreness. Theri by using the High measuring meter we inquired into whether the supplementary exercises were helpful to reducing the delayed on-set muscular soreness induced by the eccentric contraction exercises. At the same time we examined the release of enzymes such as AST, LDH and CPK in various cells of the muscIes before and after exercise in order to evaluate the state of the muscle injury caused by the exercises, and to find if the state of the injury was better because of the supplementary exercises before training. Besides, we also examlned the relation between blood lactate and the delayed on-set muscular soreness, and the effects of various supplementary exercises on the blood lactate concentration after cxercise.
