|| List of recent Aerobic-related patents
| Method for determining aerobic capacity|
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.
| Method and system for population level determination of maximal aerobic capacity|
A computerized method for determining maximal oxygen uptake for a user with incomplete data with data collected from a plurality of other users with complete data. The maximal oxygen uptake can be determined by computing similarity metrics between an incomplete data set of self-reported and measured data and complete user data sets, and using a weighted sum of the similarity metrics.
