a Change in ratings of perceived exertion (RPE) in the regular weight trials before (Pre) and 2 days after (D2) eccentric exercise (ECC) in experiment (Exp) 1 as well as from the regular weight trials to the added weight trial in Exp 2 performed after subjects had recovered from ECC-induced muscle damage. The added weight trial was arranged to simulate the increase in exercise intensity during the regular weight trials at D2. Double daggers represent significant difference between trials in each Exp (P < 0.05). Percentages in parentheses show the relative weight for exercise to maximal muscle strength. b Change in inspiratory minute ventilation (V. I) from rest to the regular weight trials and the added weight trials. Abbreviations are the same as those in Fig. 2. Values are expressed as means ± SE (n = 10)
