Worksite intervention model for facilitating changes in physical activity, fitness, and psychological parameters.
The purpose was to examine the effectiveness of a physical activity intervention which combined behavior-change strategies with a variety of physical activities for 30 sedentary adults in a 12-wk. intervention that included behavior-change strategy sessions and supervised physical activity. Before and after the intervention, psychological and physiological variables were measured. Statistically significant changes right after the intervention included (1) an increase in physical activity participation, (2) an increase in muscular endurance, flexibility, and predicted VO2 max, and (3) a decrease in the number of barriers to physical activity. Changes in physical self-perception, a psychological variable often linked to increased physical activity, were not statistically significant, but effect sizes were large. The use of behavior-change strategies in conjunction with a variety of physical activities may be useful in improving physical and psychological well-being in previously sedentary adults. Stability of change requires study.
