VO2max Testing

VO2max (ml/kg/min)

This abbreviation stands for maximal oxygen uptake.  The value reported here is one of the most important measurements obtained in the evaluation of endurance capacity and performance. The maximal oxygen uptake value represents the volume (V) of oxygen (O2) you can take-in from the air you breathe and use in the cells of your body to produce energy. The VO2max value is reported in units of millilitres of oxygen taken up from the air per kilogram of body weight per minute (ml/kg/min).

The ability to take-up oxygen is dependent on how well your heart, lungs, blood, blood vessels, and muscle cells function. Thus, VO2max represents the functional capacity of the cardiorespiratory  system. People with higher values generally have greater energy reserves, an increased work capacity, and are less easily fatigued. This means that everyday tasks now represent a smaller fraction of maximum capacity and are easier to perform.  From a performance perspective, higher VO2max values are generally consistent with better endurance performance.  World class distance runners have VO2max values over 60 ml/kg/min (women) or 70 ml/kg/min (men)

To achieve a VO2 max test result you will be required to undertake a maximal exercise test on an ergometer of your choice, (treadmill, cycle or a rowing ergo), a protocol will be specifically designed for you to achieve your maximum in about 10-14 minutes.
