Accumulating 10,000 Steps: Does This Target Meet the Current Physical Activity Guidelines? (Measurement)

Article excerpt

The purpose of this study was to detennine whether taking 10,000 steps in a day is equivalent to meeting the current physical activity guidelines of accumulating 30 mm of moderate physical activity (MPA). Fifty-nine women between the ages of 20 and 65 years wore a Yamax pedometer and GSA accelerometer (GSA) concurrently on their right hip for 1 day. The GSA was configured to collect data in 1-mm segments. GSA measured MPA was determined from the following equation established by Freedson et al. (1998): METs = 1.439 + (0.000795 counts/mm). The count range for MPA based on this equation is 1,952-5,724 counts! min (3-5.9 METs). Time spent in moderate physical activity (MPA) was calculated by summing all minutes of physical activity above 1,952 counts/min. Independent t tests were used to determine if differences in descriptive and measured variables existed between participants that accumulated at least 10,000 steps (10K+, n= 35) and participants that accumulated less than 10,000 steps (<10K, n 24). There were n o differences in the age, BMI, or the amount of time the pedometers and GSA accelerometers were worn between the 10K+ and the <10K groups. The 10K+ group accumulated significantly more steps and more minutes of MPA than the <10Kgroup (M[+ or -] SD 13,084 [+ or -] 440 steps vs. …
