Description
Summary:The aim of this study was to investigate the difference in the magnitude of muscle damage between maximal eccentric exercises of the elbow flexors (EF) and knee extensors (KE). Twelve sedentary male volunteers participated in the study. Range of motion (ROM), isometric peak torque (IPT), delayed onset of muscle soreness (DOMS), creatine kinase activity (CK), and myoglobin concentration (Mb) were evaluated before, immediately after, and on the 1(st) , 2(nd), 3(rd) , and 7(th) days following exercise. Total work (TW) during exercises was recorded and corrected by muscle volume (TWc). TWc was greater (p < 0.01) for EF [24 (2) joule·cm-3] than for KE [7 (0.4) joule·cm(-3)]. Increases in CK on the 2(nd) , 3(rd) , and 7(th) days (p < 0.01) and increases in Mb on the 1(st) , 2(nd) , 3(rd) , and 7(th) days were significantly (p
