Abstract: Maximal oxygen consumption (VO₂max) is an excellent indicator of a person’s physical fitness level. It can also be used for many other things including diagnostic tools for physicians. In this study‚ two different methods of collecting maximal oxygen uptake scores were compared. The first being the predicted VO₂max score attained via the Rockport test and the second being indirect calorimetry VO₂max score attained through cycle ergometer and an attached metabolic cart.
