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.

First claim

We claim:

1. An apparatus configured to be worn on an appendage of a user, comprising:
a processor;
a sensor;
an interface; and
a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor are configured to perform at least:
receiving, from the sensor, a data point associated with the user indicative of an athletic performance distance, d, and athletic performance time, t;
calculating a critical velocity fraction, CV fraction , based on the athletic performance time and activity type;
calculating an average velocity for the user as the athletic performance distance divided by the time;
calculating a critical velocity for the user equal to the average velocity divided by the critical velocity fraction; and
outputting the calculated critical velocity to the interface,

wherein the CV fraction =1.8677*t −0.082 for the activity type corresponding to running.

2. The apparatus of claim 1 , wherein the computer-executable instructions, when executed by the processor, further cause the apparatus to:
calculate a distance traveled below the critical velocity as the average velocity multiplied by the athletic performance time; and
calculate an anaerobic work capacity equal to the athletic performance distance minus the distance traveled below the critical velocity.

3. An apparatus configured to be worn on an appendage of a user, comprising:
a processor;
a sensor;
an interface; and
a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor are configured to perform at least:
receiving, from the sensor, a data point associated with the user indicative of an athletic performance distance, d, and athletic performance time, t;
calculating a critical velocity fraction, CV fraction , based on the athletic performance distance and activity type;
calculating an average velocity for the user as the athletic performance distance divided by the time;
calculating a critical velocity for the user equal to the average velocity divided by the critical velocity fraction; and
outputting the calculated critical velocity to the interface,
wherein the CV fraction =2.2398*d −0.09 for the activity type corresponding to running.

4. An apparatus configured to be worn on an appendage of a user, comprising:
a processor;
a sensor;
an interface; and
a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor are configured to perform at least:
receiving, from the sensor, a data point associated with the user indicative of an athletic performance power, p, and athletic performance time, t;
calculating a critical power fraction, CP fraction , fraction, based on the athletic performance time and activity type;
calculating an average power for the user as the athletic performance power divided by the time;
calculating a critical power for the user equal to the average power divided by the critical power fraction; and
outputting the calculated critical power to the interface,
wherein the CP fraction =1.9199*t −0.088 for the activity type corresponding to cycling.

5. An apparatus configured to be worn on an appendage of a user, comprising:
a processor;
a sensor;
an interface; and
a non-transitory computer-readable medium comprising computer-executable instructions that when executed by the processor are configured to perform at least:
receiving, from the sensor, a data point from a user indicative of an athletic performance power, p, and athletic performance time, t;
calculating a critical power fraction, CP fraction , fraction, based on the athletic performance power and activity type;
calculating an average power for the user as the athletic performance power divided by the time;
calculating a critical power for the user equal to the average power divided by the critical power fraction; and
outputting the calculated critical power to the interface,
wherein the CP fraction =3.0889*p −0.086 for the activity type corresponding to cycling.
