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;
- an interface;
- an oxygenation sensor, configured to be positioned proximate an area of skin of a user, the oxygenation sensor further configured to output data indicative of a tissue oxygenation of a body tissue of the user;
- 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 as the user is performing an exercise session, wherein at least a first portion of the exercise session comprises an intermittent activity;
- calculate a change in tissue oxygenation as a difference between a current tissue oxygenation value and a previous tissue oxygenation value obtained from the tissue oxygenation data, wherein the current tissue oxygenation value and the previous tissue oxygenation value are rolling averages of tissue oxygenation data points received from the oxygenation sensor during a rolling average duration;
- calculate a rate of change for the change in tissue oxygenation;
- based on the rate of change, calculate an estimated time to exhaustion for the user;
- and
- based upon the estimated time to exhaustion for the user and while the user is performing the exercise session, transmit an output configured to display a notification on the interface, wherein the notification includes a user message to alter behavior so as to result in a different time to actual exhaustion.
