推拿对一次性离心运动后延迟性肌肉酸痛的影响

背景：推拿是运动性疲劳防治的常用手段之一，但有关推拿防治延迟性肌肉酸痛疗效的客观评价较少。 目的：评价推拿对一次性离心运动后延迟性肌肉酸痛的影响。 设计、时间及地点：对比观察，于2008-04/07在南京中医药大学完成。 对象：将30名健康男性学生按照条件对等原则随机分成对照组和运动前推拿组、运动后推拿组共3组，每组10名。 方法：运动前推拿组学生于训练前在左上肢进行30 min的推拿，推拿结束5 min后开始训练。运动后推拿组学生于训练后30 min在左上肢进行30 min的推拿，并在此后的3 d内按规定的时间继续接受推拿治疗，30 min/次，1次/d。对照组学生仅参加训练，不做任何的准备活动或整理活动，也不接受任何治疗。 主要观察指标：观察训练前、训练后即刻、训练后24，48，72 h测定肌肉酸痛程度和持续时间、最大等长收缩力量、臂围、肘关节的屈伸度，训练前1 h、训练后即刻、训练后24，48 h血清肌酸激酶的变化。 结果：与对照组相比，运动前推拿组、运动后推拿组的肌肉酸痛持续时间明显缩短，酸痛的程度明显减轻(P < 0.01，P < 0.05)，运动后72 h的肌肉最大等长收缩力量的恢复明显(P < 0.01)，运动后72 h的血清肌酸激酶升高幅度明显降低。运动前推拿组运动后即刻的肘关节屈曲程度变化明显小于对照组(P < 0.05)，运动后推拿组在运动后72 h的肘关节伸直程度的恢复明显优于对照组(P < 0.05)；运动前推拿组、运动后推拿组的臂围变化与对照组无明显差异。 结论：运动前推拿能一定程度预防延迟性肌肉酸痛，减轻延迟性肌肉酸痛的严重程度，而运动后推拿能一定程度促进延迟性肌肉酸痛的恢复。

Massage effects on delayed onset muscle soreness after acute eccentric exercise

BACKGROUND: Massage is one of common methods of sport care and prevention and treatment of exercise-induced fatigue. However, the objective evaluation of massage preventing and treating delayed onset muscle soreness (DOMS) are few. OBJECTIVE: To evaluate the influence of massage on DOMS after acute eccentric exercise. DESIGN, TIME AND SETTING: The case control observation was performed at the Nanjing University of Traditional Chinese Medicine between April and July 2008. PARTICIPANTS: Thirty healthy male students were randomly divided into the control, pre-exercise massage, and post-exercise massage group, with 10 cases in each group. METHODS: Cases in the pre-exercise massage group were intervened by massage for 30 minutes, which was followed by exercise 5 minutes later. At 30 minutes after exercise, cases in the post-exercise massage group accepted massage for 30 minutes and continued massage once a day with 30 minutes a time for consecutive 3 days. There was no other intervention before or after exercise in the control group. MAIN OUTCOME MEASURES: The soreness intensity and duration time, maximal isometric strength, arm circumference, elbow flexion and extending degree prior to and immediately, 24, 48 and 72 hours after exercise. Meanwhile, serum creatine kinase (CK) was determined 1 hour before exercise, immediately, 24 and 48 hours after exercise. RESULTS: Compared to the control group, the duration time of muscle soreness were significant reduced and shorter in the pre-exercise massage, and post-exercise massage groups (P < 0.01, P < 0.05), the maximal isometric strength was obviously recovered in the post-exercise massage at 72 hours after exercise (P < 0.01), the rising range of serum CK of pre-exercise massage group at 72 hours after exercise was significant lower. Moreover, the change of elbow flexion degree at immediately after exercise was much less than the control group (P < 0.05), while the recovery of elbow extending degree of pre-exercise massage group at 72 hours after exercise was much better than the control group (P < 0.05). In addition, there was no significant difference in the change of arm circumference among the three groups. CONCLUSION: Pre-exercise massage can partially prevent DOMS, and reduce the severity of DOMS, while post-exercise massage can speed up the recovery of DOMS in certain degree.
