Does voluntary hyperventilation-induced hypocapnic alkalosis slow the adaptation of pulmonary O2 uptake during moderate-intensity exercise in young male adults?

Population

8 young male adults

Intervention

Voluntary hyperventilation-induced hypocapnic alkalosis (RALK; PET,CO2, approximately 20 mmHg) during moderate-intensity exercise (step-transition from 20 W cycling to 90% of estimated lactate threshold)

Comparator

Control condition (CON; PET,CO2, approximately 40 mmHg) during the same exercise protocol

Outcome

Pulmonary O2 uptake (VO2) kinetics (time constant for phase 2 VO2 response, tau VO2) and muscle deoxygenation (tauHHb, DeltaHbtot)surrogate

Hyperventilation-induced hypocapnic alkalosis slows the adaptation of pulmonary O2 uptake during moderate-intensity exercise, suggesting a reduction in local muscle perfusion and O2 delivery.
