Cadence as a Behavioral Target in Physical Activity Interventions: A Narrative Review.

Behavioral interventions targeting moderate- to vigorous-intensity physical activity (MVPA) to ensure health benefits can be strengthened by a simple metric that helps adults understand if they are exercising at the target intensity. Laboratory studies have established that a cadence of 100 steps/min is equivalent to MVPA, but intervention application is largely unexplored. The aim of this narrative review was to describe how cadence has been implemented in behavioral interventions. PubMed, PsychInfo, and SCOPUS were searched with a standardized search string. Studies were included if peer-reviewed interventions reporting on targeting MVPA increases for adults through cadence or if non-intervention programs directly targeting cadence. Of 232 unique studies identified, 6 were included in the final sample. Cadence was monitored using subjective cues (n = 3), time-oriented goals (n = 2), step-counting (n = 2), auditory cues (n = 2), and visual cues (n = 2), and measured by pedometers (n = 5) or mp3 player (n = 1). No studies reported detailed participant instructions to teach cadence. Results suggest that use of cadence in behavioral interventions is feasible but nascent. Reviewed studies provided insufficient detail to replicate methods and there was no consensus on best practices for implementing cadence. Results point to the potential utility of cadence and offer approaches for future refinement and standardization.
