From: Cadence (steps/min) and relative intensity in 21 to 60-year-olds: the CADENCE-adults study
Relationship between cadence and relative intensity indicators (%HRMax = %Heart rate maximum; %HR reserve = %Heart rate reserve; RPE = Rate of Perceived Exertion) using a segmented regression model by age groups. Red line is the mean relative intensity value at each corresponding cadence value, and black lines are the 95% prediction intervals. Blue horizontal dotted lines represent moderate and vigorous intensity threshold for each indicator.
