This paper reports the results of an experiment designed to prove or disprove the theory that controlled exercise during extreme stress could significantly reduce fatigue. The nature of mental fatigue is thoroughly discussed as well as many of the factors which cause this condition. The experiment was constructed from a statistics final examination. Two statistics classes were divided into three randomized sections, each receiving a different activity treatment level. Section three was given a seven minute exercise period, Section two was given a seven minute rest period, and Section one was given no rest and immediately began work on the second portion of the exam. Analytical results showed no difference in the mean scores of the three sections. This leads to the conclusion that controlled exercise does not have an effect on performance. A discussion of blocking is presented as an explanation of the results. Experimental design and related topics are presented for further research. Author
