Abstract
The effects of several levels of exercise on inappropriate behaviors of four trainable mentally impaired students were observed. Treatment conditions, which occurred as the first daily activity, included: Phase I, daily alternating conditions of warm-up exercises and jogging at a moderate rate for a short distance; Phase II, daily alternating conditions of no-exercise periods and jogging at a vigorous rate for a moderate distance; and Phase III, jogging at a vigorous rate for a moderate distance on consecutive days. For one student two additional conditions occurred, Phase IV, long-distance jogging on consecutive days at a vigorous rate and Phase V, consecutive days of no exercise. Observations of three inappropriate behaviors of each student occurred immediately after, 1 hour after, and 2 hours after each exercise period. Results indicate a decrease in all three inappropriate behaviors for three of four students and an inverse relationship between the level of exercise and the amount of inappropriate behavior for three of four students. Improvements over existing studies are discussed with suggestions for future research.
