This paper investigates the periodic variation in human performance predicted by Biorhythm theory. Fourier analysis was performed on performance data of three subjects. The results indicated that the postulated basic biorhythmic cycles exist. Comparison of the phase of predominate experimental frequency with the phase predicted by biorhythm indicated that the frequencies may not be as stable as the theory suggests.
