Cadence (steps/min) and relative intensity in 21 to 60-year-olds: the CADENCE-adults study

Table 5 Summary of heuristic thresholds selected for all relatively- and absolutely-defined^a intensity indicators by age groups

	Intensity Indicators
Age Group	Relative Moderate Intensity (≥ 64%HR_max, ≥ 40%HRR, ≥ 12 RPE)	Absolute Moderate Intensity^a (≥ 3.0 METs)	Relative Vigorous Intensity (≥ 77%HR_max, ≥ 60%HRR, ≥ 14 RPE)	Absolute Vigorous Intensity^a (≥ 6 METs)
Group 1 (21–30 years)	120	100	135	130
Group 2 (31–40 years)	120	100	130	130
Group 3 (31–40 years)	115	100	125	130
Group 4 (41–50 years)	110	100	120	130

HR maximum [HR_max] = 220 - age. Heart rate reserve [HRR] = HR_max - HR_resting. METs Metabolic equivalents. RPE Rate of Perceived Exertion. 1 MET = 3.5 mL·kg⁻¹·min⁻¹ of O₂ uptake. ^aCadence-based heuristic thresholds for absolutely-defined intensity are retrieved from Tudor-Locke et al. [20, 21]
