Characterization of Physical Activity and Sedentary Time Across College Years

Abstract

The purpose of this study was to characterize physical activity (PA), sedentary time (ST), and body composition across collegiate years. 143 participants (Age: 19.7±1.2yrs) were measured using a modified four compartment model and the Long International Physical Activity Questionnaire. Two-way ANOVAs and Pearson Correlations were utilized. For males, PA and ST were significant across class year. Vigorous PA and ST were significantly correlated to %body fat (p=0.001 and p=0.036, respectively) and fat mass (p=0.002 and p=0.023, respectively) suggesting vigorous PA and reduced ST may be associated with improved body composition. Males expressed differences in PA and ST across class year while females were stable.
