Abstract
The aims of this study were to estimate the walking cadence required to elicit a VO2reserve (VO2R) of 40 % and determine if fitness status moderates the relationship between walking cadence and %VO2R. Twenty participants (10 male, mean(s) age 32(10) years; VO2max 45(10) mL.kg-1.min-1) completed resting and maximal oxygen consumption tests prior to 7 x 5-min bouts of treadmill walking at increasing speed while wearing an Apple Watch and measuring oxygen consumption continuously. The 7 x 5-min exercise bouts were performed at speeds between 3 and 6 km.h-1 with 5-min seated rest following each bout. Walking cadence measured at each treadmill speed was recorded using the Apple Watch ‘Activity’ app. Using Bayesian regression, we predict that participants need a walking cadence of 138 to 140 steps.min-1 to achieve a VO2R of 40 %. However, these values are moderated by fitness status such that those with lower fitness can achieve 40 % VO2R at a slower walking cadence. The results suggest that those with moderate fitness need to walk at ~40 % higher than the currently recommended walking cadence (100 steps.min-1) to elicit moderate-intensity physical activity. However, walking cadence required to achieve moderate-intensity physical activity is moderated by fitness status.
