 The article discusses the use of pedometers and accelerometers to monitor physical activity in terms of steps taken per day. It highlights the emergence of various step-based versions of physical activity guidelines, but notes a discrepancy in the exact values being communicated. The author suggests that step-based recommendations should be consistent with existing evidence-based public health guidelines that emphasize time spent in moderate to vigorous physical activity, MVPA. The article provides normative data indicating that healthy adults typically take between 4,000 and 18,000 steps per day, with 10,000 steps being a reasonable goal. It also notes that interventions have shown incremental increases of around 2,000 to 2,500 steps per day. The author suggests that a cadence of 100 steps per minute is indicative of moderate intensity walking and can be used as a guiding value for daily recommendations. The article concludes by suggesting that a scale that spans a wide range of incremental increases in steps per day and incorporates step-based translations of recommended amounts of time in MVPA may be useful in research and practice. It emphasizes the importance of good reference data and evidence-based recommendations for users of objective monitoring instruments to design effective health messages, guide behavior change, and measure and track steps taken per day.
