Performance characteristics during finger flexion exercise at 75% work rate peak to fatigue for control (Con, CaCO₃, 0.3 g kg⁻¹) and alkalosis (Alk, NaHCO₃, 0.3 g kg⁻¹)

Trial	Mean force (N)	Mean power output (W)	Fatigue time (min)
Variability 1	16.6 ± 0.9	2.86 ± 0.16	10.1 ± 0.8
Variability 2	16.9 ± 0.8	2.89 ± 0.14	10.2 ± 0.8
CV (%)	3.3 ± 0.6	3.1 ± 0.6	2.1 ± 0.5
Con	16.5 ± 0.9	2.95 ± 0.12	10.2 ± 0.8
Alk	16.8 ± 0.8	2.98 ± 0.16	12.7 ± 1.2†

Mean ± s.e.m., n = 9 for Con and Alk, and for pre-experiment variability trials, n = 12. Coefficient of variation was calculated from variability trials 1 and 2.

^†Alk greater than Con (P < 0.05).
