RESULTS

The relationship between the different methods of determining heart rate are presented in Figures 1 - 3. There is a significant linear relationship which is maintained from resting to heart rate values at maximal exercise. There are no significant differences between methods of determining heart rate. The MIO Lifestyle watch compares favorably with the direct ECG signal and the values determined with the portable telemetric heart rate monitor.

OBSERVATIONS

Heart Rate Accuracy
The determination of heart rate with the MIO Lifestyle watch operates on the same electrophysiological principles as the direct ECG and the portable telemetric heart rate technology. It is not surprising, therefore, that the accuracy is similar. The correlation between methods is excellent (R2 > 0.98).

The MIO Lifestyle watch has the advantage of not requiring a chest strap or chest electrodes. The chest strap can be annoying to some individuals, particularly if they wear it for extended periods of time. Although the lack of a chest strap is an advantage, it does introduce human error into the measurement of heart rate. There are several factors that contribute to the determination of heart rate using the MIO watch and these must be considered for each individual. The shape of the wrist and interface with the watch, the skin conductance, the amount and direction of pressure on the watch sensors all determine the success in obtaining an ECG signal. In the 30 minute aerobic task, the MIO watch was successful in obtaining a signal 79% of the time, compared to the direct ECG and portable telemetric heart rate device, which both received the signal 100% of the time. These factors are primarily related to gaining familiarity with the watch and the success in obtaining a signal will increase with use.
