This study aimed to compare the accuracy of the power output, measured by a
power meter, with respect to the speed, measured by an inertial measurement unit
(IMU) and a global navigation satellite system (GNSS) sport watch to determine the
critical power (CP) and speed (CS), work over CP (W') and CS (D'), and long‐duration
performance (i.e., 60 min). Fifteen highly trained athletes randomly performed seven
time trials on a 400 m track. The CP/CS and W'/D' were defined through the inverse
of time model using the 3, 4, 5, 10, and 20 min trials. The 60 min performance was
estimated through the power law model using the 1, 3, and 10 min trials and
compared with the actual performance. A lower standard error of the estimate was
obtained when using the power meter (CP: 2.7 [2.1–3.3] % and W': 13.8 [10.4–17.3]
%) compared to the speed reported by the IMU (CS: 3.4 [2.5–4.3] %) and D': 20.7
[16.6–24.7] %) and GNSS sport watch (CS: 3.4 [2.5–4.3] % and D': 20.6 [16.7–24.7]
%). A lower coefficient of variation was also observed for the power meter (4.9 [3.7–
6.1] %) Regarding the speed reported by the IMU (10.9 [7.1–14.8] %) and GNSS
sport watch (10.9 [7.0–14.7] %) in the 60 min performance estimation, the power
meter offered lower errors than the IMU and GNSS sport watch for modelling
endurance performance on the track.
