System and method for determining performance capacity

A system for determining performance capacity, the system comprising:

• a wearable device, comprising:
• a biosensor configured to measure biometrics including a heart rate of a user;
• and
• a motion sensor configured to monitor activity of the user;
• a processor coupled to the biosensor and the motion sensor, the processor configured to process electronic signals generated by the biosensor and the motion sensor;
• and
• a non-transitory computer-readable medium operatively coupled to the processor and storing instructions that, when executed, cause the processor to:
• generate biometric data including a heart rate variability (HRV) of the user from the biometrics of the user measured by the biosensor;
• generate activity data from the activity of the user monitored by the motion sensor;
• generate a predicted HRV score of the user when a signal for determining the heart rate of the user from the biosensor is unavailable, wherein the predicted HRV score is based on the generated biometric data and the generated activity data;
• generate a fatigue score from the generated activity data;
• create a response profile for the user based on the fatigue score and the predicted HRV score;
• and
• provide the response profile to the user, wherein the response profile indicates a capacity of the user to perform an activity.
