Background and Purpose: Positive effects of pedometer-metered steps and motivation on body composition have not been documented in healthy adults. This study determined the effects of: 1) 4- weeks of pedometer-metered walking and steps on body composition, fasting blood glucose (FBG), blood pressure (BP), diet changes, waist-to-hip ratios (WHR), and 2) daily motivation on step count. Methods: For 4-weeks, participants (n=29, 24 ± 3.8yo) wore a pedometer and recorded daily steps. Subjects were randomized into two groups: 1) daily motivational quotes (MQ) (n=19) to determine changes in step counts and 2) a control group (no MQ). Measurements were performed baseline, at study end; and 3 randomized 3-day diet records were collected. Results: Waist and hip circumference decreased significantly (p=0.002 & p=0.03) in both groups and decreased fat free mass (FFM) approached significance (p=0.06). Decreased fruit intake was observed in the second (p=0.007) and third (p=0.023) diet records. Conclusion: Motivation did not increase steps or changes in FBG and BP. However, WHR decreased in both groups suggesting that 4-weeks of pedometer walking results in positive abdominal changes. Additional longer-term studies are needed to examine these physical changes as well as investigate the decreased fruit intake.
