From: Cadence (steps/min) and intensity during ambulation in 6–20 year olds: the CADENCE-kids study
Scatterplots of cadence and ln(METy) for 6–17 year olds, and cadence and ln(METs) for 18–20 year olds. Fitted regression lines and 4 and 6 METy or 3 and 6 METs intensity levels are superimposed. METy = youth metabolic equivalents calculated as mass-specific VO2 (mL·kg·min− 1) divided by resting mass-specific VO2 (estimated using the Schofield equation). METs = metabolic equivalents calculated as mass-specific VO2 [mL·kg·min− 1] divided by 3.5 mL·kg·min− 1
