Title: | Basal and stress-induced salivary testosterone variation across the menstrual cycle and linkage to motivation and muscle power | Contributor(s): | Cook, C J (author) ; Kilduff, L P (author); Crewther, B T | Publication Date: | 2018-04 | Early Online Version: | 2017-12-21 | DOI: | 10.1111/sms.13041 | Handle Link: | https://hdl.handle.net/1959.11/31805 | Abstract: | This study investigated salivary testosterone (sal-T) variation across the menstrual cycle in female athletes, at different competitive levels, and its association with motivation and neuromuscular power. Six elite and 16 non-elite female athletes were monitored on days 7 (D7), 14 (D14), and 21 (D21) across 3 menstrual cycles for basal sal-T concentrations and self-appraised motivation to train and compete. Two further measures were taken on D7, D14, and D21 across 2 menstrual cycles: (1) the sal-T response (delta change) to a physical stress test and (2) peak power (PP) response to a 6-second cycle sprint following a post-activation potentiation (PAP) stimulus. Basal sal-T concentrations increased by 17 ± 27% from D7 to D14 before decreasing by −25 ± 43% on D21 (P < .05), but this result was biased by elite females with higher sal-T (>102%) who showed larger menstrual changes. Motivation, sal-T reactivity to stress, and the PP responses to a PAP stimulus also varied by testing day (P < .05), in parallel with basal sal-T and in favor of the elite group. Furthermore, stronger within-subject relationships (P < .001) between basal sal-T and motivation emerged in the elites (r = .70-. 75) vs the non-elite group (r = .41-.50). In conclusion, menstrual cycle changes in sal-T were more obvious in high-performing female athletes with higher sal-T concentrations. This was accompanied by greater training motivation, a more pronounced sal-T response to a physical stressor and greater neuromuscular power in the elite group. These results support observations that female athletes with higher T are more represented at elite levels of performance. | Publication Type: | Journal Article | Source of Publication: | Scandinavian Journal of Medicine & Science in Sports, 28(4), p. 1345-1353 | Publisher: | Wiley-Blackwell Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1600-0838 0905-7188 |
