Changes in aerobic capacity after exhaustive endurance exercise.

Parameters	Exhaustion (min)	MHR (beats/min)	${\dot{\mathbf{V}}\mathbf{O}}_{\mathbf{2}\mathbf{peak}}$ (mL/kg/min)
LCS	63.13 ± 3.35 (5.30%)	198.58 ± 9.97 (5.02%)	52.33 ± 6.66 (12.72%)
Placebo	63.28 ± 3.37 (5.33%)	198.00 ± 9.49 (4.79%)	53.11 ± 6.44 (12.13%)

The data are presented as mean ± standard deviation (coefficient of variation) (n = 12). Time until exhaustion was recorded for running at 90% ${\dot{\mathrm{V}}\mathrm{O}}_{2\max }$ immediately after 60 min of exercise at 70% ${\dot{\mathrm{V}}\mathrm{O}}_{2\max }$. LCS, low-osmolality carbohydrate–electrolyte solution; MHR, maximal heart rate; ${\dot{\mathrm{V}}\mathrm{O}}_{2\mathrm{peak}}$, peak oxygen intake.
