Chronoendocrinological studies in athletes. III. Certain psychoendocrinological correlations

In 83 healthy athletes, statistically highly significant circadian rhythms of psychological parameters (as measured with the SAN-questionnaire [8]: feelings of well-being, activation [1], mood) have been validated and quantified by cosinor analysis. There were significant correlations between some personality factors, as measured with Cattell 16PF questionnaire, in 32 fencers, and some mean circadian hormone blood concentrations. No significant correlations have been found between parameters measured with Eysenck test or with the D48 test and the mean circadian blood levels of T3, TSH, CSL, T, HGH, IRI.
