Abstract

A method of estimating the maximal oxygen uptake of an individual on the basis of heart rate data, biometric data, biomechanical data, and geophysical data is described. These data can be collected as the individual engages in activities requiring various levels of exertion, without modifying those activities from the ordinary manner in which they are performed. In particular, in some embodiments the method described here obviates the conventional need for a laboratory setting when estimating maximal oxygen uptake and the method can be applied to estimate maximal oxygen uptake under more natural conditions than conventional testing protocols requiring treadmills or stationary ergometers typically permit. Furthermore, it is described how such estimates of maximal oxygen uptake can be used to estimate other quantities of interest, including fat and carbohydrate metabolism, lactate production, and water and electrolyte loss during exercise.

Dependent claims

A computerized method for dynamically measuring maximal oxygen uptake of a user in real-time during aerobic activity, the method comprising:

(a) electronically measuring instantaneous heart rate data, instantaneous biomechanical data, and instantaneous geophysical data of the user over a period of time, using one or more sensors;
(b) setting an oxygen uptake model for the user and storing the oxygen uptake model in memory of a computer;
(c) determining, using the computer, a maximum heart rate of the user and storing the maximum heart rate in memory;
(d) determining, using the computer, a plurality of instantaneous oxygen uptake estimates over the period of time based in part on user data including the maximum heart rate, the instantaneous biomechanical data, and the instantaneous geophysical data, wherein the user data is selected and related to the plurality of instantaneous oxygen uptake estimates using the oxygen uptake model;
(e) evaluating, using the computer, a relationship between a real-time heart rate relaxation constant and a real-time maximal oxygen uptake of the user based at least in part on the plurality of the instantaneous oxygen uptake estimates, the maximum heart rate, the instantaneous heart rate data, the instantaneous biomechanical data, and the instantaneous geophysical data, wherein the real-time heart rate relaxation constant comprises a numerical parameter that measures a rate at which the heart rate of a user changes in response to oxygen demand;
and
(f) determining, using the computer, a maximal oxygen uptake for the user during the aerobic activity, using the relationship between the real-time heart rate relaxation constant and the real-time maximal oxygen uptake.
