The purpose was to determine whether there were significant difference in attitudes toward certain dimensions of physical activity between a group of undergraduates enrolled in wellness-based courses and a group of undergraduates enrolled in activity-based courses. Of additional interest were the subjects’ gender, ideal body weight by gender, classification, and frequency of weekly participation in physical activity. The subjects for this investigation consisted of undergraduate students enrolled in a wellness-based or an activity-based course in the Spring 2001 semester at Texas A&M University-Commerce. Each student participated in Kenyon’s Attitudes Toward Physical Activity Inventory. This instrument was a pre/post test design that measured certain dimensions of physical activity. The subdomains were analyzed along with the subjects’ gender, ideal body weight by gender, classification, and frequency of weekly participation in physical activity using a one-way ANCOVA or a two-way ANCOVA statistical analysis. The statistical analysis revealed a significant difference in the pretest and posttest mean compared to the grand mean in the ascetic experience and social experience subdomain for the wellness-based and activity-based courses. The aesthetic experience, catharsis, health & fitness, and pursuit of vertigo subdomains had no significant difference between the pretest and posttest means compared to the grand mean in each subdomain of the wellness-based and activity-based courses by group. The demographics of gender, ideal body weight by gender, classification, and frequency of weekly participation in physical activity revealed no significant difference in the pretest and posttest mean compared to the grand mean of each subdomain of the wellness-based and activity-based courses. The undergraduates enrolled in the wellness-based courses and in the activity-based courses agreed in their attitudes toward certain dimensions of physical activity according to gender, ideal body weight by gender, classification, and frequency of weekly participation in physical activity; however, the two distinct groups disagreed in their attitudes toward certain dimensions of physical activity when compared by group.
