2.3.4. Maximal Oxygen Uptake
BRUCE
A VO2max test was conducted by adopting the classic Bruce athlete scheme for an incremental load exercise on a running platform [To ensure that VO2max was achieved, at least three of the following criteria had to be met: (1) With an increase in exercise load, the oxygen uptake platform appears or oxygen uptake decreases; (2) with an increase in exercise load, HR does not increase; (3) respiratory quotient reaches or approaches 1.15; and (4) the RPE scale has reached the exhaustion level and can no longer maintain the current exercise load.
