<p>The goal of this study was to determine the suitability of optical heart rate sensors for forwarder driving heart rate measurement. In the forestry and Forest Products Research Institute, a circuit with straight lines and curves (curve radius of 6 m and 8 m) was installed, and forwarder driving experiments were conducted for three participants. The Apple Watch (Apple Inc.), a wristwatch-type optical heart rate sensor, and myBeat (WHS-1, Union Tool Co.), a chest-worn electrocardiogram monitoring device, were used to measure heart rate. Furthermore, in this test, the labor load was equivalent to driving on forest roads with an empty 2-ton truck, which was less than forwarding including loading and unloading. The average of the measured differences between the two sensors was −0.51 bpm. As a result of the Bland-Altman analysis. Because more than 99% of bias measurements were within ±20% of the mean, it was discovered that the optical heart rate sensor can produce results as accurate as a conventional electrocardiograph. As a result of the time series analysis, Apple Watch was able to obtain the structural change in heart rate, and it was thought that it could be effective for detecting labor burden.</p>
