  Figure 1. Data analysis flow showing participants in analysis (n) and number of matched heart rate time points. BMI: body mass index; HR: heart rate.

• 

  Laboratory phase: Bland-Altman plot between the heart rate data from the Polar H10 and the Tempo HR. Light blue dotted lines show the limits of agreement, and the dark blue dotted line shows the mean of the difference. HR: heart rate.

• 

  Laboratory phase: box plot providing by-decile comparisons of mean Polar H10 (white) and Tempo HR HR data (gray). HR: heart rate; bpm: beats per minute.

• 

  Laboratory phase: Bland-Altman plot between the heart rate data from the Polar H10 and the Polar A370. Light blue dotted lines show the limits of agreement, and the dark blue dotted line shows the mean of the difference. HR: heart rate.

  Laboratory phase: box plot providing by-decile comparisons of mean Polar H10 (white) and Polar A370 HR data (gray). HR: heart rate; bpm: beats per minute.

  Free-living phase: Bland-Altman plot between the heart rate data from the Polar H10 and the Tempo HR. Light blue dotted lines show the limits of agreement, and the dark blue dotted line shows the mean of the difference. HR: heart rate.
