Early and continued participation in a work-site health and fitness program.

This study examines social-environmental, physical-behavioral, and psychological factors influencing early and continued participation in physical activity. Data for the study were collected during the first six months of operation of a work-site Health and Fitness Center. The following sources were used to collect data (N = 403): 1) printouts of frequency of employee visits to the Health and Fitness Center; 2) a questionnaire; and 3) fitness files. Data measuring early (month one) and continued (month six) participation were obtained from printouts of frequency of employee visits. A questionnaire measured estimation of physical ability, attraction to physical activity, youth participation, social support, and convenience of the Health and Fitness Center. Fitness files were used to obtain measures of cardiovascular fitness, percent body fat, and recent participation. Linear discriminant analysis was conducted to determine the practical usefulness of the social-environmental, physical-behavioral, and psychological factors for classifying employees into categories of exercise adherers and nonadherers. A measure of exercise adherence was based on company policy of six visits each month. Results for early participation (month one) indicated that convenience, sex, youth participation, attitudinal commitment, and age discriminated (p less than .05) among adherers and nonadherers with 63% accuracy. At the end of six months, attitudinal commitment, sex, convenience, and estimation of physical ability discriminated (p less than .05) among adherers and non-adherers with 60% accuracy. In addition, when early participation in the health and fitness program served as the measure of recent participation for the six month analysis, recent participation and attitudinal commitment discriminated (p less than .05) between the two adherence categories with 75% accuracy. Adherers and nonadherers were classified with 66% and 85% accuracy, respectively.
