Abstract [eng] Background and objective: Unaccustomed eccentric or eccentric–concentric exercise leaves us stiff and sore the next day and can cause muscle damage. The data about the residual effect of prior eccentric–concentric exercises on oxygen uptake (VO2) during constant cycling exercise in women or the data about differences of such effect between genders are scarce. Therefore, the aim of this study was to assess differences of the residual effect of PDJ on VO2 during HCE and indirect muscle damage parameters between women and men. Materials and methods: The study aimed to asses differences of the residual effect of prior drop jumps (PDJ) on oxygen uptake (VO2) during heavy cycling exercise (HCE) and indirect muscle damage parameters between men (n = 8) and women (n = 11). On four different days participants performed one incremental cycling exercise and three HCE (control [CON], 45 min [450 PDJ] and 24 h [24 h PDJ] after 100 drop jumps). The intensity of HCE was set to work rate corresponding to 50% of the difference between the second and the first ventilatory thresholds which were determined analyzing pulmonary gas exchange parameters during incremental cycling exercise. Capillary blood samples were collected in order to measure blood lactate concentration immediately after HCE and serum creatine kinase (CK) activity 24 h after PDJ. Subjects rated perceived exertion and delayed onset muscle soreness (DOMS) using 20 and 10 point scales, respectively. Results: VO2 at 3–6 min of HCE performed 450 after PDJ was significantly increased as compared to CON HCE only in the male group. Both men and women felt moderate muscle pain. CK activity was significantly increased 24 h after PDJ in the male group. Both during HCE 450 PDJ and 24 h PDJ, the significant positive correlation was observed between relative changes of VO2 during steady state of HCE and CK activity only in the male group. [...].
