Abstract
The purpose of this study is to investigate the correlation and agreement between heart rates of Polar heart rate monitor and a smartwatch in order to confirm the accuracy of heart rate measured by the smartwatch. Heart rates of fifty college students were measured for a total of 12 minutes under four conditions: rest, walk, Zumba, and cycle. As a result of correlation and agreement analysis between heart rates of the two devices, correlation coefficient (r) was 0.995 at rest, 0.991 at walk, 0.923 at Zumba, 0.932 at cycle, and Bland-Altman ratio (BA ratio) was 0.02 at rest, 0.03 at walk, 0.06 at Zumba, 0.04 at cycle. Heart rate from smartwatch showed high correlation and agreement with heart rate from Polar in all conditions, representing that smartwatch can be considered an reliable apparatus to measure hear rate.
