目的：探讨反复离心运动对延迟性肌肉酸痛(DOMS)患者疼痛和肌肉压痛影响的时间规律。设计和设置：受试者完成两次相同的偏心运动，间隔6、7、8或9周。这项实验是在生物动力学研究实验室进行的。研究对象：男16例，女15例，年龄24.59±4.42岁，身高171.71±7.81 cm，体重73.00±11.20 kg。测量：在每一次偏心运动前即刻和运动后0，24，48，72h分别测量DOMS的两个生理特征。感觉到的疼痛使用视觉模拟评分(VAS)，肌肉压痛使用点状压痛仪(PTG)测量。结果：对VAS和PTG数据进行了两组4x2x5(x组x时间)的重复测量和时间因素的方差分析。VAS和PTG数据的组、回合和时间有显著的主效应(P<；0.05)。没有检测到显著的相互作用。事后分析显示，9周组的疼痛程度明显低于8周组。与任何其他组相比，7周组的压痛明显减少，8周组的肌肉压痛明显更多。所有受试者在运动前感觉到的疼痛和肌肉压痛均明显低于运动后0小时和24小时。结论：对于与DOMS相关的感觉疼痛和肌肉压痛，有效的预防方法是在类似的运动之前大约6-9周进行一次离心性运动。
OBJECTIVE: To determine the temporal pattern of the repeated bout effect of eccentric exercise on perceived pain and muscular tenderness associated with delayed-onset muscle soreness (DOMS). DESIGN AND SETTING: Subjects completed 2 identical eccentric exercise bouts separated by 6, 7, 8, or 9 weeks. The experiment was conducted in a biokinetics research laboratory. SUBJECTS: Sixteen male and 15 female untrained subjects (age = 24.59 +/- 4.42 years, height = 171.71 +/- 7.81 cm, weight = 73.00 +/- 11.20 kg). MEASUREMENTS: Two physiologic characteristics of DOMS were measured immediately before and 0, 24, 48, and 72 hours after each eccentric exercise bout. Perceived pain was measured using a visual analog scale (VAS), and muscular tenderness was measured using a punctate tenderness gauge (PTG). RESULTS: Two 4 x 2 x 5 (group x bout x time) analyses of variance with repeated measures on the bout and time factors were performed on the VAS and PTG data. Significant (P <.05) main effects were found for group, bout, and time for the VAS and the PTG data. No significant interactions were detected. Post hoc analysis revealed significantly less perceived pain for the 9-week group than the 8-week group. The 7-week group had significantly less and the 8-week group had significantly more muscular tenderness than any other group. Perceived pain and muscular tenderness were significantly less after exercise bout 2 than after exercise bout 1. All subjects had significantly less perceived pain and muscular tenderness pre-exercise than 0 and 24 hours after the eccentric exercise bouts. CONCLUSIONS: An effective prophylaxis for perceived pain and muscular tenderness associated with DOMS is the performance of an eccentric exercise bout 6 to 9 weeks before a similar exercise bout.
