Despite the ethnicity of an individual college student, a majority of college students do not partake in the recommended amount of exercise according to the American College Health Association (2013). Therefore, both the obesity and overweight rates with college students were reported as 29% in 2000 and 32.5% in 2009 (ACHA, 2010). The purpose of this quantitative, cross-sectional study was to examine whether Ajzen's Theory of Planned Behavior (TPB) determinants explains physical activity among college students in North Carolina universities. 100 university students who enrolled in lifetime fitness classes from two institutions were asked to participate in completing an online Leisure-Time questionnaire for a period of two weeks. Partial correlations were used to determine relationships between the TPB determinants of attitude, subjective norm, descriptive norm, perceived behavior control, intention, and physical activity among the college students. The primary results from the partial correlation analysis revealed that the intention and attitude determinants had the largest significant impact on whether the university students engaged in exercise. Future studies should focus on investigating whether the intention and attitude determinants have substantial influence on physical activity on college students in the regions of the United States with high obesity rates, i.e., Mississippi and Alabama.
