Participant Characteristics.
Figure 1.
Measured %HRmax (n = 129) and %HRpeak (n = 35) during Light, Moderate and Vigorous Effort Treadmill exercise.
* Significant difference at P<0.0001. •%HRmax = Observed HR/(220-age) (sub-sample, n = 35). ▴%HRpeak = Observed HR/(HRpeak VO2 treadmill test) (sub-sample, n = 35). ▪%HRmax = Observed HR/(220-age) (population, n = 129). Cross-hatched boxes = %HRmax range: 50–63% light effort; 64–76% moderate effort; 77–93% vigorous effort.
Figure 2.
Accuracy of the self-estimated PA Intensity across A) Ethnicity, B) Sex, C) Body Mass Index (BMI) and Age (D) as confirmed by measured %HRmax.
*Significant difference at P<0.05. Grey bars- below %HRmax range. White bars- within %HRmax range. Black bars- above %HRmax range. %HRmax range: 50–63% light effort; 64–76% moderate effort; 77–93% vigorous effort.
