The Effect Of IMT Upon Maximum Lactate Steady-State And Blood Lactate Concentration

“Several studies have reported that improvements in endurance performance following respiratory muscle training (RMT) are associated with a decrease in blood lactate concentration. This study examined whether pressure threshold inspiratory muscle training (IMT) elicits an increase in the cycling power output corresponding to the maximum lactate steady state.


“Data supports previous observations that IMT results in a decrease in blood lactate concentration at a given intensity of exercise. That such a decrease in blood lactate concentration was not associated with a substantial (>2.5%) increase in maximum lactate steady state power is a new finding suggesting that RMT-induced increases in exercise tolerance and reductions in blood lactate concentration are not ascribable to a substantial increase in the ‘lactate threshold’.
