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’.

Inspiratory Muscles Can Be Trained To Increase Strength Or Endurance

“This study examined whether resistive loading can train the inspiratory muscles differentially.”


“Results demonstrate that pressure threshold resistive inspiratory muscle training can be utilised to train specifically for improvements in strength or endurance and that the improvements are maintained well post-training.”

Acute Cardiorespiratory Responses To Inspiratory Pressure Threshold Loading

“The purpose of this study was to test the acute responses to differing pressure threshold inspiratory loading intensities in well-trained rowers.“


“Although all loads elicited a sustained increase in forced capacity, only the 60% load elicited a sustained rise in mean arterial blood pressure, diastolic blood pressure, and systolic blood pressure, providing evidence for a metaboreflex response at this load.”

Development And Evaluation Of A Pressure Threshold Inspiratory Muscle Trainer For Use In The Context Of Sports Performance

“Inspiratory muscle training (IMT) became widespread, particularly in a clinical context, and at the time of this research a pressure threshold training device suitable for training the inspiratory muscles of healthy humans did not exist. The purpose of this paper was to document the design and development of such a device – the POWERbreathe.
