Knowing the criteria for achieving VO2max or peak VO2 are;

- Maximum oxygen consumption (VO2max) is reached when O2consumption no longer increases or increases by less than 150 ml /min despite an increase in workload (in the absence of a plateau atthe end of one test, the term VO2 peak is more appropriate).- Heart rate plateau despite increased exercise intensity.- A venous concentration of lactic acid after exercise of more than8 mmol / L.- A respiratory exchange of more than 1.15- A score of more than 9 on the Perception of Effort scale (scaleof 0-10).- The subject can no longer maintain the rhythm (cannot maintainthe RPM).* Must have the majority of the criteria to have a VO2max.

Mohammed, a 24 year old male who weighs 71 kg and is 178 cm tallshows this data;

*The time column will show intervals of the speed of thetreadmill and the incline percentage

Does Mohammed reach a VO2 max or a VO2peak? Explain Why, andwhat is the value of the VO2 max or peak is.

VO2max = 3.5 + (0.2 ? speed in mph ? 26.8) + (0.9 ? speed in mph? 26.8 ? fraction of% incline)
