The aim of the study was to suggest a simplified approach to the study of the slow component of V.O2. The study was conducted on 34 people aged 26.38±15.8 yrs with fitness levels of V.O2 max 44.14±9.9 ml/kg/min.
These people were given an incremental ramping test designed to reveal loads at the 1st ventilatory threshold and at maximum aerobic power. The initial V.O2 plateau value was also identified and a constant intensity test under a wide range of loads was given for the visual identification of the slow component of V.O2. In all subjects slow V.O2 occurred after the end of the steep rise phase in the respiratory exchange ratio (RER) which is characteristic of initial effort.
The hope is expressed that our proposal will promote the more widespread use of above-threshold V.O2 kinetics.
