From: Cadence (steps/min) and relative intensity in 61 to 85-year-olds: the CADENCE-Adults study
Relationship between cadence and relative intensity indicators (A) %Heart rate maximum (%HRmax); B) %Heart rate reserve (%HRR); and C) Rate of Perceived Exertion (RPE), using a segmented regression model. Red line is the mean relative intensity value at each corresponding cadence value, and black lines are the 95% prediction intervals. Blue dotted and dash-dotted lines represent, respectively, moderate and vigorous intensity thresholds
