Abstract
Purpose
Continuous incremental protocols (CP) may misestimate the maximum aerobic velocity (Vmax) due to increases in running speed faster than cardiorespiratory/metabolic adjustments. A higher aerobic capacity may mitigate this issue due to faster pulmonary oxygen uptake (\(\dot{V}\)O2) kinetics. Therefore, this study aimed to compare three different protocols to assess Vmax in athletes with higher or lower training status.
Methods
Sixteen well-trained runners were classified according to higher (HI) or lower (LO) \(\dot{V}\)O2max \(\dot{V}\)O2-kinetics was calculated across four 5-min running bouts at 10 km·h−1. Two CPs [1 km·h−1 per min (CP1) and 1 km·h−1 every 2-min (CP2)] were performed to determine Vmax \(\dot{V}\)O2max, lactate-threshold and submaximal \(\dot{V}\)O2/velocity relationship. Results were compared to the discontinuous incremental protocol (DP).
Results
Vmax, \(\dot{V}\)O2max, \(\dot{V}\)CO2 and VE were higher [(P DP for LO. A lower [P
