摘      要：Purpose Pedometers can be an effective tool to increase step counts in a physically inactive *** a more active population,pedometers may also be useful for further increasing physical activity and improving cardiovascular disease risk *** purpose was to assess the adherence and determine the health impact of a 100,000 steps/week(14,286 steps/day)goal in a somewhat-active(7500-9999 steps/day)to active(10,000-12,500 steps/day)*** Thirty-two apparently healthy subjects,13 males(age 44±14 years)and 19 females(age 39±13 years)who had a baseline activity level between 7500 and 12,500 steps/day,were *** were assessed prior to and 16 weeks after completing a 100,000 steps/week ***-and post-assessments of health included body composition,rest-ing blood pressure,blood lipid profile,fasting blood glucose,and a 3-min walk test to estimate cardiorespiratory *** Fifty-three percent of participants adhered(≥90,000 steps/week)to the 100,000 steps/week physical activity program yet all participants increased their stepping by 23,303±11,480 steps/*** increased stepping,significant improvements in body composition were *** included reduced body mass index(pre:27.2±3.6 kg/m^(2);post:26.9±3.6 kg/m^(2);P=0.026),reduced total percent body fat(pre:35.7±9.9%;post:34.3±10.4%;P0.001),and reduced waist circumference(pre:83.8±10.2 cm;post:81.5±10.0 cm;P=0.001).An unexpected increase was observed for low density lipoprotein cholesterol(pre:109.7±22.7 mg/dL;post:117.6±20.4 mg/dL;P0.05).Conclusions Individuals who were previously somewhat-active or active can gain additional health benefits,particularly improvements in body composition,by increasing to 100,000 steps/week with the use of a pedometer.
