Claim 6:
7. A device for assessing exercise fatigue, comprising:
a heart rate sensor configured to obtain exercise heart rates, a resting heart rate and a maximum heart rate of a user;
an exercise load computation model based on the exercise heart rates, the resting heart rate and the maximum heart rate;
a computation module configured to calculate a chronic training load (CTL) and an acute training load (ATL) based on the exercise heart rates and the exercise load computation model, and calculate a training stress balance (TSB) based on the CTL and the ATL; and
a matching module configured to determine a fatigue level based on the TSB;
wherein the exercise load computation model is: TR=Σ1TB*C*TK, wherein TR denotes an exercise load, T denotes the user's continuous exercise time for each time, B=(exercise heart rate−resting heart rate)/(maximum heart rate−resting heart rate), C=P1*eP2*B, P1 is a constant between 0.1 and 0.5, P2 is a constant between 2.5 and 7, and TK is a temperature influence coefficient obtained by querying a temperature influence coefficient table recording multiple influence coefficients of different temperatures om exercise load; the resting heart rate is a heart rate value of the user when the user reaches an extreme exercise state.
