Validity of Hera Leto consumer earbuds for heart rate monitoring during stationary cycling
Hera Leto demonstrated high validity in HR measurement across different exercise intensities, as shown in Table 2. While Verity Sense and Vantage V performed comparably under steady-state and HIIT conditions, their HR readings showed greater deviations during severe-intensity constant load exercise (≥ 130% Pmax), particularly during the ON phases.
Hera Leto exhibited the lowest overall MAE and MAPE values and the highest CCC, compared to Polar Verity Sense and Polar Vantage
