摘要：Unaccustomed eccentric-based exercise is known to induce muscle damage (MD). The objective of this study was to investigate the responses to downhill walking (DW) sessions in young adults, assessing MD and aerobic markers. Eight male subjects were submitted to a 4-week DW periodized exercise programme. Subjects’ soreness (SOR) was assessed every training day. Serum creatine quinase activity (CK) was collected before the first training session, and at the end of weeks 1-4. Oxygen uptake (VO2) and perceived exertion (PE) were assessed during the last training session every week. Increases in SOR were found only at the third and fourth training days. Increased CK concentration was found at the third training week. No significant increases in VO2 and PE were found throughout the programme. We concluded that DW sessions elicit significant MD, but not enough to impair further sessions. Therefore, DW can be adopted as a training method, allowing proper periodization.
