Abstract: Beware: This Project contains FAKE data. Not only, but mostly! It is just an educational project Theoretical Background Heart rate recovery (HRR) following exercise is an established parameter for assessing autonomic function and cardiovascular health. A rapid decline in heart rate after physical activity primarily reflects efficient parasympathetic reactivation and has been identified as a strong predictor of cardiovascular and all-cause mortality (Cole et al., 1999; Nishime et al., 2000). Traditionally, reference values and cut-offs for HRR have been derived from predominantly male populations, despite clear evidence for sex-specific differences in both resting heart rate and post-exercise autonomic regulation (Allison et al., 2014; St. Pierre et al., 2022). Recent research suggests that hormonal fluctuations across the menstrual cycle, especially changes in estrogen and progesterone levels, may further influence cardiovascular responses in women (da Fonseca et al., 2024). Progesterone, which dominates the luteal phase, is associated with increased resting heart rate and altered autonomic function compared to the follicular phase. However, findings on the direct impact of menstrual cycle phases on HRR remain mixed. While some studies report negligible differences in HRR between cycle phases (Yazar et al., 2016), others indicate that individual variability and methodological limitations may obscure subtle effects (da Fonseca et al., 2024). Building on these findings, the current study specifically addresses whether heart rate recovery differs between the follicular and luteal phases in women (H1), and whether recovery is poorer in the luteal phase compared to the follicular phase (H2).
