To test these hypotheses, photoplethysmographic and electrocardiographic (ECG) signals were compared. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> Thirty participants (50% female) randomly performed two 13\u2032 sequences (3\u2032 rest, 5\u2032 submaximal-intensity exercise, and 5\u2032 passive recovery) on a motorized treadmill and a bicycle ergometer. Heart rate was measured concomitantly with a 10-lead ECG, a chest-strap monitor, and 2 wrist photoplethysmography monitors (Polar Unite) with different tightening (free vs imposed at the maximum tolerable). <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> The level of association (<jats:italic>r<\/jats:italic>) and coefficient of variation (CV; ie, the error of measurement) of the Polar Unite versus the 10-lead ECG is affected by the tightness of the wristband (normal vs high; <jats:italic>r<\/jats:italic>\u2009=\u2009.83 and .96, CV\u2009=\u200916.1 and 8.1% for the treadmill, respectively; <jats:italic>r<\/jats:italic>\u2009=\u2009.71 and .97, CV\u2009=\u200920.3% and 6.2% for the bicycle, respectively) by the phase of the signal (transition vs steady state; <jats:italic>r<\/jats:italic>\u2009=\u2009.90 and .97, CV\u2009=\u20099.0% and 7.6% for the treadmill, respectively; <jats:italic>r<\/jats:italic>\u2009=\u2009.93 and .99, CV\u2009=\u20097.5% and 3.1% for the bicycle, respectively) and movement of arms (treadmill vs bicycle; <jats:italic>r<\/jats:italic>\u2009=\u2009.90 and .93, CV\u2009=\u20099.0% and 7.5% during the transition phase, respectively; <jats:italic>r<\/jats:italic>\u2009=\u2009.97 and .99, CV\u2009=\u20097.6% and 3.1% during the steady-state phase, respectively). <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> The accuracy of heart rate measured with a wrist photoplethysmography monitor is affected by the tightness of the wristband and the phase of the signal.
