研究了离心运动的功能和生化结果之间的相关性以及这些结果与“延迟性肌肉酸痛”（DOMS）之间的相关性。27名男性受试者在前臂屈肌120次最大离心收缩后5天内测定最大等张力、手肘伸屈角度、肌酸激酶活性和血清肌红蛋白浓度。在运动后1至96小时的力（r = 0.55至0.96）、屈曲（0.52至0.94）、伸展（0.41至0.95）和肌红蛋白（0.55至0.97）以及24至96小时的肌酸激酶（0.67至0.96）和DOMS（0.45至0.72）之间发现了显著相关性。集群的显着相关性（0.32至0.91）被发现之间的所有功能和生化指标。然而，DOMS与其他参数的相关性很低（0.34至0.63）。这些结果实际上可以解释如下：1）当离心运动后的早期偏差较大时，受试者需要更多的时间才能完全恢复，2）一个测量值的较大变化伴随着其他测量值的较大偏差，3）离心运动的客观结果是比DOMS评分更准确的参数，用于效果研究。
Correlations between functional and biochemical outcomes of eccentric exercise and between these outcomes and "delayed-onset muscle soreness" (DOMS) were studied. Maximal isotonic force, extension and flexion angle of the elbow, creatine kinase activity, and myoglobin concentration in serum were measured in 27 male subjects during 5 days after 120 maximal eccentric contractions of the forearm flexors. Significant correlations were found between values at 1 to 96 h after exercise for force (r = 0.55 to 0.96), flexion (0.52 to 0.94), extension (0.41 to 0.95), and myoglobin (0.55 to 0.97) and at 24 to 96 h for creatine kinase (0.67 to 0.96) and DOMS (0.45 to 0.72). Clusters of significant correlations (0.32 to 0.91) were found among all functional and biochemical measures. DOMS, however, showed only few and lower correlations with the other parameters (0.34 to 0.63). These results can practically be interpreted as follows: 1) subjects need more time to recover completely when early deviations after eccentric exercise are large, 2) a large change in one measure is accompanied by large deviations in other measures, and 3) objective outcomes of eccentric exercise are more accurate parameters than a DOMS score for use in effect studies.
