摘要：Background/Aim. Heart rate variability (HRV) and heart rate recovery (HRR) show differences between genders, and dissimilarities were also reported in women in various menstrual cycle (MC) phases. The aim of this research was to analyze cardiac autonomic indices during rest and in re-covery after the Wingate test between genders in the young, sedentary population and to investigate whether a MC phase in women can influence these indi-ces. Methods. Twenty-five females (20.5 ± 0.7 years) and sixteen males (20.4 ± 0.7 years) performed the Wingate anaerobic test on a cycle ergometer while their HRR and resting and recovery HRV indices were obtained. In fe-males, data were collected during three distinctive MC phases. Results. The natural logarithm of low-frequency (lnLF) HRV marker and the natural logarithm of high-frequency (lnHF) HRV marker were higher in males dur-ing rest compared to women in all MC phases, except in the late follicular phase, where no differences in lnHF be-tween genders were observed. Markedly higher lnLF and lnHF were recorded in males after the Wingate test. There were no differences in HRV between women in various MC phases during rest. Surprisingly, parasympathetic time-domain marker (the square root of the mean squared dif-ferences of successive NN intervals, RMSSD) and lnLF were both higher in the early follicular phase in compari-son to the luteal phase of MC during recovery. HRR was faster in men in comparison to women in all MC phas-es. Conclusion. Males show greater HRR and total varia-bility during rest and recovery, but it appears that resting parasympathetic activity is similar when females are in the late follicular phase of MC. Intra-female resting autonomic variability is not affected by the sex hormonal cycle. Post-exercise HRV in the early follicular phase reflects a signifi-cantly favourable autonomic profile in comparison to the luteal phase of MC.
