Pedometers are becoming widely accepted as measurement and motivational devices for increasing physical activity by both researchers and practitioners. Pedometer utility is limited however without evidence-based guidelines for interpreting steps/day and providing important feedback on incremental changes. Research continues to accumulate focused on addressing the question of “How many steps are enough?” A recent study directly determined pedometer cut points that correspond to minimal moderate intensity walking on a treadmill: 96 steps/min in men and 107 steps/min in women, or roughly 100 steps/min for both. Translating these cut points in terms of accepted daily public health guidelines produces approximately 3000 steps in 30 minutes of moderate intensity ambulatory activity for both genders. Since cross-sectional data exist indicating that Americans average approximately 5000-6000 steps/day, adding an additional 3000 steps day would produce a day end total of 8000-9000 steps/day. Recently Tudor-Locke and Bassett proposed preliminary indices be used to classify pedometer-determined physical activity in healthy adults: 1) <5000 steps/day indicated a “sedentary lifestyle index”, 2) 5,000-7,499 steps/day is considered “low active”; 3) 7,500-9,999 is considered “somewhat active”; and 4) >10,000 steps/day indicates the point that should be used to classify individuals as “active”. Individuals who take >12,500steps/day are classified as “highly active”. Individuals should be encouraged to move up a level in order to attain additional health benefits. Moving up a level is congruent with a 3000 steps/day increase, again in agreement with existing public health guidelines. All pedometer-based guidelines at this time are preliminary and require additional scrutiny prior to widespread acceptance.Keyword(s): disease prevention, health promotion, physical activity
