Biorhythms are inherent cycles which regulate memory, coordination endurance, temperature, emotions, and much more, we each have three fundamental Biorhythms cycles. The purpose of this study was to determine the relationship between Biorhythm and Sport Performance among Hamadanain athletes participating in individual sport fields brought in BiorhythmTheory The type of research method employed in this study was the descriptive-correlated one and 216 subjects were selected as the statistical sample. At this point, the measurement tool consists of Biorhythm software and sport performance questioners Charbonneau. In order for analysis the data, in addition to the indexes of descriptive inferential statistics such as Pearson correlation coefficient, chi-square, independent T-test, One- Way Variance Analysis was also employed. The findings showed that there is a significant relationship among athletes' performance Intellectual cycles. The results of chi- square showed a significant difference among the results of match and situations of Emotional and Intellectual cycles. There was not a significant difference between the average of emotional energy and the results of match.The result of one-way ANOVA revealed a significant relationship among different statuses of Intellectual and Emotional cycles and athletes' performance. In general, the different situations of Emotional and Intellectual cycles existing in Biorhythmtheory can enhance the sport Performance. So, regarding the different situations of Emotional and Intellectual cycles can help the trainers make better plan to exercise for participating and selecting athletes in sensitive matches.
