Table 1. Mean (SD) values of swimming velocity (v), blood lactate concentrations ([La-]), heart rate (HR), and percentage of maximal oxygen uptake ($\mathbf{\%}\dot{\mathbf{V}}{\mathbf{O}}_{\mathbf{2}\mathbf{max}}$) are shown at 97.5, 100 and 102.5% of the maximal lactate steady state (MLSS) (N = 10).

[La-] (mmol.L-1)	1.48 (0.39)	1.89 (0.77)	2.97 (0.87)1,2
HR (beats.min-1)	167.1 (15.0)	173.6 (9.7)	179.3 (9.2)1
$\%\dot{\mathrm{V}}{\mathrm{O}}_{2\max }$ (%)	78.9 (8.7)	84.7 (3.8)1	90.9 (4.6)1,2
