评估了三组受试者在两次30分钟的下坡跑(-10度坡度)运动后感觉到的肌肉酸痛等级、血清肌酸激酶(CK)活性和肌红蛋白水平。第1、2和3组的两轮比赛分别相隔3、6和9wk。分别于运动前、运动后6h、18h、42h进行标准化测量。在第一场比赛中，三组在运动后42h报告了最大的酸痛。此外，组1、组2和组3的CK相对增加分别为340、272和286%。肌红蛋白的相应值分别为432、749和407%。当重复相同的运动时，第1组和第2组的疼痛显著减少，CK和肌红蛋白的增加也较小。例如，第2轮时，第1组和第2组CK增加的百分比分别为63%和62%。第3组的肌肉酸痛分级、CK活性和肌红蛋白水平在第1轮和第2轮之间没有显著差异。结论：单次运动对肌肉酸痛的产生和持续6wk的血清蛋白反应具有预防作用。
Perceived muscle soreness ratings, serum creatine kinase (CK) activity, and myoglobin levels were assessed in three groups of subjects following two 30-min exercise bouts of downhill running (-10 degrees slope). The two bouts were separated by 3, 6, and 9 wk for groups 1, 2, and 3, respectively. Criterion measures were obtained pre- and 6, 18, and 42 h postexercise. On bout 1 the three groups reported maximal soreness at 42 h postexercise. Also, relative increases in CK for groups 1, 2, and 3 were 340, 272, and 286%, respectively. Corresponding values for myoglobin were 432, 749, and 407%. When the same exercise was repeated, significantly less soreness was reported and smaller increases in CK and myoglobin were found for groups 1 and 2. For example, the percent CK increases on bout 2 for groups 1 and 2 were 63 and 62, respectively. Group 3 demonstrated no significant difference in soreness ratings, CK activities, or myoglobin levels between bouts 1 and 2. It was concluded that performance of a single exercise bout had a prophylactic effect on the generation of muscle soreness and serum protein responses that lasts up to 6 wk.
