Two methods of introducing obese adolescents to aerobic exercise were compared. A fast-start group began with five aerobic sessions per week and gradually reduced these to three over a period of 12 weeks. A slow-start group began with one per week and gradually increased to three. A control group had an equivalent amount of time in interactive group sessions and nonaerobic activity. The program was assessed by physical fitness, anthropometry, and attendance. Results were analyzed by multivariate analysis. The method of introducing exercise to the subjects produced no significant differences on measures of fitness or anthropometry. Significant effects for time were shown for strength, push-ups, body mass index, the sum of five skinfolds, gluteal and abdominal circumferences, weight, and percent overweight. Significant differences in the absenteeism rates were shown among groups. However, no relationship was found between absenteeism and changes in weight or overall fitness levels.
