After determination of the lactate threshold (LT) and maximal (V) over dotO(2) ((V) over dotO(2max)), 14 untrained subjects (UG) and 14 well-trained cyclists (TG) performed on different days and in random order, rest to moderate-intensity exercise transitions (6 minutes at 80% of LT), preceded by either no prior exercise or prior supramaximal exercise (PSE: two bouts of 1 minute at 120% of (V) over dotO(2max), with a 1-minute rest in between). Baseline (V) over dotO(2) was significantly increased (p < 0.05) by PSE in both groups (UG: 0.39 +/- 0.06 vs. 0.51 +/- 0.15 L . min(-1); TG: 0.37 +/- 0.06 vs. 0.58 +/- 0.14 L . min(-1)). In the TG group, the steady state (V) over dotO(2) was significantly increased by PSE (TG: 2.21 +/- 0.38 vs. 2.07 +/- 0.27 L . min(-1), p < 0.05; UG: 1.60 +/- 0.27 vs. 1.60 +/- 0.29 L . min(-1), p > 0.05). It can be concluded that aerobic fitness level influences the effects of PSE on (V) over dotO(2) response during moderate-intensity exercise. [J Exerc Sci Fit . Vol 7 .
