Disclosed are various approaches for determining the maximum oxygen consumption of a person, also known as maximum aerobic capacity or VO.sub.2 Max. A person is positioned on a treadmill. Attached to the person is a harness configured to apply a horizontal force to the person. A work rate for the person can be calculated based at least in part on the magnitude of the horizontal force applied by the harness and the velocity of the belt. The maximum oxygen consumption for the person can then be calculated based at least in part on the previously calculated work rate.

An electric training apparatus is configured to apply, by a load motor, a load on a rotating body configured to apply a load on an exercising person, detect an exercise physiological response value of the exercising person and a number of revolutions of the rotating body, perform control for gradually increasing the load of the load motor toward a set load upper limit value so that a detection result of the exercise physiological response value of the exercising person approaches a target exercise physiological response value set in advance, and change, before an exercise or during the exercise by the exercising person, the load upper limit value in response to a control command input based on a state of the exercising person, a state of the control, and a perceived exertion scale for the exercising person.

A system and method for adaptive fitness testing is provided. A fitness testing application manages fitness tests on a fitness testing apparatus by collecting physiological data and calculating various performance metrics.
