Abstract
Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.
Claims20
An apparatus, comprising:
- a processor;
- a user interface;
- an oxygenation sensor;
- and
- a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor are configured to perform at least:
- receive tissue oxygenation data from the oxygenation sensor associated with at least two exercise periods, at least a portion of each of the at least two exercise periods associated with a severe exercise intensity domain, and the at least two exercise periods having differing durations;
- calculate a total number of tissue oxygenation points for each of the at least two exercise periods;
- calculate an exercise period summary data point for each of the at least two exercise periods as a total number of tissue oxygenation points versus a duration of exercise;
- calculate a regression through the exercise period summary data points for the at least two exercise periods;
- calculate a critical tissue oxygenation percentage for a user equal to a slope of at least a portion of the regression;
- receive, from the user interface, responses to a questionnaire from the user;
- calculate and store a user athletic profile based on the questionnaire responses;
- receive an input of a rate of perceived exertion value from the user following an exercise session;
- map the rate of perceived exertion value to an oxygen consumption scale, based upon the stored user athletic profile;
- estimate, based on the map, an estimated volume of oxygen consumption of the user;
- generate a graphical user interface comprising the estimated volume of oxygen consumption of the user and the calculated critical tissue oxygenation percentage;
- and
- output, to a display device, the graphical user interface.
