Abstract

The influence of training status on the oxygen uptake ( O2) response to heavy intensity exercise in pubertal girls has not previously been investigated. We hypothesised that whilst training status-related adaptations would be evident in the O2, heart rate (HR) and deoxyhemoglobin ([HHb]) kinetics of...
