The effect of caffeine and Temazepam on performance during exercise in two mental performance tasks

Mental performance during exercise depends on the balance between the level of fatigue and the level of arousal (Tomporowski and Ellis, 1986). To determine the role of arousal in the exercise-mental performance relationship, observations of mental performance under differing conditions of arousal need to be made. Such manipulation can be achieved through the administration of pharmacological agents that either stimulate or depress the central nervous system (CNS).
