High-Intensity Interval Training leads to reduced testosterone and increased estrogen levels in young women

Background: Hormone levels can be determined according the prevalence of a balance between generation metabolism and clearance rates. High-Intensity Interval Training (HIIT) can affect this balance through a variety of mechanisms, including competition-associated stress, diet, body composition, heat production and hypoxia. Aims: : The present study aimed to evaluate the impact of HIIT on the Health hormones of femininity and fertility in young women. Methods: : The study was comprised of Eighteen females aged 18.06 ± 0.128 years old. The participants were subjected to an eight-week training program (3 sessions/week, two hours (h) after lunch). Participants underwent basal pre-and post-exercise intervention tests, such as reproductive and trophic hormones. Results: : The results revealed that 143.16% increased estrogen levels and a 62.12% reduction in testosterone levels . No significant differences were detected in Luteinizing hormone (LH) and Prolactin (PRL) between participants. Conclusions: : HIIT exercise training in young women decreases testosterone levels and increases estrogen levels, with no effect on trophic hormones (LH, PRL).
