Blood lactate concentration (N = 227).

	Condition
	Control		Exercise
	M	SD	M	SD
Before treatment	1.35	0.56	1.05	0.35
After treatment	1.07	0.40	10.19	2.76
After switching task	0.95	0.29	1.86	0.73
Contrast	−2.48	0.88	6.68	2.74

Lactate concentration was measured in mmol/l. Contrast was calculated as the lactate concentration after treatment (control, exercise) subtracted by the lactate concentration at the individual anaerobic threshold in the fitness test.
