- The amount of oxygen the body can take in and use in one minute
- Maximum volume of oxygen that can be consumed during maximal workout
- Maximum oxygen consumpton attainable during maximal work
VO2 = Volume of oxygen consumed
Factors Affecting VO2 max:
- Training intensity
- Amount of haemoglobin in the blood
- Amount of capilalries around the lungs and the working muscles
For training aimed at improving a performers VO2 max using the aerobic system the work - relief ratio is normally longer in duration and intensity, just below the anaerobic threshold.
The relief ratio is typically shorter (1:1) which helps reduce the OBLA and delay muscle fatigue and therefore prolong the aerobic system adaptations.
some elite marathon runners or cross country skiiers can perform up to 90% of their VO2 max without significant lactic…
