Background: Brisk walking is recommended as a form of health-enhancing physical activity. This study determines the steps/minute rate corresponding to self-paced ‘brisk’ walking (SPBW); a predicted steps/minute rate for moderate physical activity (MPA) and a comparison of the two findings.

Methods: A convenience sample (N=58, 34 men;24 women, 31.7±7.7yrs), wearing pedometers and a heart rate (HR) monitor, performed SPBW for 10 minutes and five indoor sessions, regulated by a metronome (ranging from 60-120 steps/minute). Using steps/minute and HR data of the trials, a steps/minute rate for MPA was predicted. Adjustments were subsequently made for aerobic fitness (using maximal oxygen uptake (VO2 max) estimates), age and gender as possible contributors to stepping rate differences.

Results: Average steps/minute rate for SPBW was 118±9 (116±9;121±8-men/women, respectively; p=0.022); predicted steps/minute rate for MPA was 122±37 (127±36;116±39-men/women, respectively; p<0.99) and was similar to steps/minute rate of SPBW (p=0.452), even after adjusting for age, gender and aerobic fitness.

Conclusion: Steps/minute rates of SPBW correlates closely with targeted HR for MPA, independent of aerobic fitness; predicted steps/minute rate for MPA relates closely to steps/minute rates of SPBW. Our findings support current PA messages that use the term ‘brisk’ walking as a reference for MPA.
