Blood Lactate AUC Is a Sensitive Test for Evaluating the Effect of Exercise Training on Functional Work Capacity in Patients with Chronic Heart Failure

Table 3

Comparisons of training effect in two supervised intervention groups and controls.

	Recommended regular exercise; n = 8		Moderate continuous training; n = 9		Aerobic interval training; n = 6
	Baseline	12 weeks	Baseline	12 weeks	Baseline	12 weeks
VO2peak (ml/kg/min)	17.0 ± 5.2	17.9 ± 6.4	21.3 ± 1.2	22.7 ± 2.0	17.6 ± 3.6	17.2 ± 2.8
6 MWT (meters)	492 ± 56	476 ± 115	554 ± 75	609 ± 89	483 ± 33	542 ± 61
Lactate AUC (mmol/L x minutes)	126 ± 43	106 ± 24	107 ± 36	78 ± 20	175 ± 84	90 ± 25

Mixed ANOVA is used to detect differences between groups. Data are mean ± SD. VO2_peak is maximum oxygen uptake. Lactate AUC is Lactate area under the curve. Difference from baseline between groups p < 0.05.
