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.
Claims17
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 power sensor configured to output data indicative of a power consumption of the user;
- 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 during an exercise session comprising at least a portion of a total exercise time exercising within a severe exercise intensity domain;
- calculate a change in tissue oxygenation as a difference between a current tissue oxygenation value and a previous tissue oxygenation value;
- and
- compare the change in tissue oxygenation to a threshold change value and a threshold duration, wherein the comparison is indicative of a critical power value
- wherein if the change in tissue oxygenation is less than or equal to the threshold change value, and a change in tissue oxygenation persists for a first duration greater than or equal to the threshold duration, output a signal to the interface indicating a critical power value equal to a current power indicated by the power sensor,
- wherein if the change in tissue oxygenation is greater than the threshold change value or the change in tissue oxygenation persists for a second duration less than the threshold duration, output a signal to the interface indicating that the current power indicated by the power sensor is not equal to the critical power of the user,
- wherein the apparatus is configured to be worn on an appendage of the user, and
- wherein the oxygenation sensor utilizes near infra-red spectroscopy.
