Examination of Moderate Physical Activity in College Students: Is 10,000 Steps Enough to Meet the Current Recommendation?

Scott B. Hawkins, Timothy K. Behrens and Mary K. Dinger, University of Oklahoma, Norman, OK

The accumulation of 10,000 steps per day has been promoted to the general public as an approach to achieve the current public health physical activity recommendation. Although the 10,000 steps approach is gaining notoriety, its relationship with the current recommendation has not been examined in college students. The purpose of this study was to examine the relationship between time spent in moderate physical activity (MPA) and number of steps accumulated throughout the day (STEPS) in college students. A sample of 36 college students (gender: 18 females, 18 males; age: 23.3 ± 3.1 yrs; BMI: 25.5 ± 4.1 kg/m2) participated in this cross sectional descriptive study. Participants concurrently wore an Actigraph® 7164 accelerometer and a Yamax™ DW200 pedometer for at least 12 hours per day for 7 consecutive days. Data from the accelerometer were downloaded and reduced using SAS, version 8.1. Accelerometer counts were used to categorize the subjects into two groups: 1) those meeting the current public health physical activity recommendation (accumulating ³ 30 minutes of MPA/day) and 2) those not meeting the recommendation (accumulating < 30 minutes of MPA/day). Descriptive statistics, t-tests, and correlation coefficients were calculated. Overall, participants averaged 31.9 ± 16.8 minutes in MPA and 9,940.4 ± 2,867.1 STEPS. Females did not differ significantly from males in MPA (t = 1.21, df = 34, p=0.23) or STEPS (t = 0.11, df = 34, p= 0.91). There was a significant and positive relationship between time spent in MPA and STEPS (r = 0.69, p < 0.0001). There was a significant difference (t = 3.97, df = 34, p = 0.0004) in STEPS between those meeting the recommendation (n = 15) and those not meeting the recommendation (n = 21). Those meeting the recommendation accumulated 11,821.9 ± 2,682.3 STEPS while those not meeting the recommendation accumulated 8,596.5 ± 2,190.4 STEPS. The results of this study indicate that the students meeting the recommendation averaged more than the increasingly popular 10,000 steps per day. This suggests that 10,000 steps a day may not be sufficient for college students to satisfy the current physical activity recommendation.
