Accelerometer-measured versus self-reported physical activity in college students: implications for research and practice.

Objective: To determine the level of moderate-vigorous-intensity physical activity (MVPA) assessed via self-report and accelerometer in the college population, and to examine intrapersonal and contextual variables associated with physical activity (PA).

Participants: Participants were 77 college students at a university in the northwest sampled between January 2011 and December 2011.

Methods: Participants completed a validated self-report measure of PA and measures of athletic identity and benefits and barriers to exercise.
