VO2 max and anaerobic threshold are predictors of your endurance. Both are very important if you are training for an endurance event or want to know your training parameters.
V02 Max (Maximal Aerobic Power Testing)
V02 max is the maximum amount of oxygen that can be used by muscles in a given period of time. VO2 max is your maximal rate of oxygen consumption and a measure of your capacity to generate the energy required for endurance activities.
To assess VO2 max, the athlete performs progressively intensive exercise, during which ventilation and oxygen concentration of inhaled and exhaled air are measured. VO2 max testing is performed on a bike or treadmill and a metabolic analysis is done.
The results provide max levels of heart rate, VO2, VCO2 and anaerobic threshold.
Anaerobic threshold testing, also called lactate threshold testing, measures the point at which lactate removal fails to keep up with the rate of lactate production as exercise intensity increases. At the anaerobic threshold, lactate starts to accumulate in the blood because it is produced faster than it can be removed (metabolized).
The anaerobic threshold is a useful measure for determining exercise intensity for training and racing in endurance sports. Athletes can increase their lactate threshold through proper training.
