Enhanced cerebro-cardiovascular responses before starting voluntary exercise in young men with higher peak aerobic capacity
Abstract
The delay of oxygen transport to muscle at the onset of exercise by the cardio-respiratory system increases anaerobic energy production and oxygen deficit, which can disturb a smooth start of exercise. We found that the anticipatory cerebro-cardiovascular responses evoked by a countdown before starting voluntary exercise were enhanced as peak aerobic capacity increased, suggesting that the central as well as peripheral mechanisms contribute to increasing aerobic energy production at the onset of exercise.
