A running test (RPE\n TP<\/jats:sub>\n ) elicits reproducible plasma cortisol and testosterone elevations (in a healthy state) and may detect blunted hormonal responses in overreached\u00a0athletes. This current study determined the salivary cortisol and testosterone responses reproducibility to the RPE\n TP<\/jats:sub>\n , to provide greater practical validity using saliva compared with the previously utilized blood sampling. Second, the relationship between the salivary and plasma responses was assessed.\n \n Methods<\/jats:bold>\n :\n <\/jats:italic>\n A total of 23 active, healthy males completed the RPE\n TP<\/jats:sub>\n on 3 occasions. Saliva (N\u2009=\u200923) and plasma (N\u2009=\u200913) were collected preexercise, postexercise, and 30 minutes postexercise.\n \n Results<\/jats:bold>\n :\n <\/jats:italic>\n Salivary cortisol did not elevate in any RPE\n TP<\/jats:sub>\n trial, and reduced concentrations occurred 30 minutes postexercise (\n P<\/jats:italic>\n \u2009=\u2009.029,\n \u03b7<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u2009.287); trial differences were observed (\n P<\/jats:italic>\n \u2009<\u2009.001,\n \u03b7<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u2009.463). The RPE\n TP<\/jats:sub>\n elevated (\n P<\/jats:italic>\n \u2009<\u2009.001,\n \u03b7<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u2009.593) salivary testosterone with no effect of trial (\n P<\/jats:italic>\n \u2009=\u2009.789,\n \u03b7<\/jats:italic>\n 2<\/jats:sup>\n \u2009=\u2009.022). Intraindividual variability was 25% in cortisol and 17% in testosterone. \u201cFair\u201d intraclass coefficients of .46 (cortisol) and .40 (testosterone) were found. Salivary and plasma cortisol positively correlated (\n R<\/jats:italic>\n \u2009=\u2009.581,\n P<\/jats:italic>\n \u2009=\u2009.037) yet did not for testosterone (\n R<\/jats:italic>\n \u2009=\u2009.345,\n P<\/jats:italic>\n \u2009=\u2009.248).\n \n Conclusions<\/jats:bold>\n :\n <\/jats:italic>\n The reproducibility of salivary testosterone response to the RPE\n TP<\/jats:sub>\n is evident and supports its use as a potential tool, subject to further confirmatory work, to detect hormonal dysfunction during overreaching.
