6 profoundly mentally retarded youth were provided a 5-wk. stair-climbing program to improve cardiorespiratory fitness behavior. Three subjects were provided verbal plus food reinforcement and the other three received verbal reinforcement during the intervention phase. Based on the visual inspection of the data, both types of reinforcement increased the number of steps taken and exercise time.
