Improving fitness of dually diagnosed adults.

Lack of prior research led to this study on the effect of a physical fitness program combined with a token economy reinforcement system on the physical fitness of 22 dually diagnosed adults of a day-treatment program. Between pre- and posttests, subjects participated in a 12-wk, training program of 40 to 45 min. of exercise three times a week. Subjects received tokens after each session in which they participated actively. Analysis indicated significant differences between pre- and posttest scores for muscular endurance, cardiorespiratory endurance, and flexibility but not for body composition.
