The Beep Test is often used to determine your VO2 Max
Vo2max is simply the maximum volume of oxygen the body is able to process at any given time during high-intensity exercise. A more technical description is that vo2max is the maximum amount of oxygen, measured in millilitres, that the athlete’s body can utilize in a period of one minute, per kilogram of body weight.
Through the right type of training conducted at the right intensity, it is possible to increase an athletes vo2max. For those wanting to improve their beep test score, an increase in Vo2Max is a by-product of the right training, however, it is the increase in beep test score that matters!
I hope this puts Vo2Max into perspective as it relates to the beep test.
