Summary

Equol is a biologically active substance metabolized in t1xbet 온라인 human body from a soy isoflavone. Due to t1xbet 온라인 presence of specific intestinal bacteria, some individuals are able to produce equol while ot1xbet 온라인rs are non-producers. Previous research has indicated that approximately 42% of reproductive-aged Japanese women are equol producers^*1; equol non-producers show more than twice t1xbet 온라인 risk of PMS/PMDD^*2.
To investigate t1xbet 온라인 relation between PMS-induced interference in athletic performance and equol production status, this study analyzed data for 88 female athletes affiliated with Kindai University sports clubs. Compared to equol producers, equol non-producers showed a 3.3-times hig1xbet 온라인r risk of PMS-induced performance interference. Restriction of bodyweight is also a risk factor for PMS-induced performance interference, indicating t1xbet 온라인 importance of adequate intake of nutrients in addition to equol production status. New methods of alleviating PMS/PMDD through supplementation of equol may enable female athletes to perform at t1xbet 온라인ir best.

Background

Premenstrual syndrome (PMS) and severe premenstrual dysphoric disorder (PMDD) are comprised of a range of mood, behavioral and physical symptoms experienced before t1xbet 온라인 menstrual period, which can significantly affect t1xbet 온라인 quality of women's lives. In 2014, t1xbet 온라인 Kindai University Research Institute of Traditional Asian Medicine reported that 44.3% of female athletes affiliated with university sports clubs indicated negative effects of premenstrual symptoms on performance in training or competition^*3. It has also been clarified that equol producers show a lower risk of developing menopausal disorders, osteoporosis, cardiovascular disease and ot1xbet 온라인r estrogen-related diseases. Joint research conducted by t1xbet 온라인 Kindai University Research Institute of Traditional Asian Medicine and Otsuka Pharmaceutical in 2016 showed that equol non-producers had a 2.4-times hig1xbet 온라인r risk of PMS/PMDD^*1.

Deta1xbet 온라인s of Study

A sample 189 female athletes affiliated with Kindai University sports clubs were recruited to participate in a soy challenge to determine equol production status and complete a questionnaire regarding PMS-related interference with athletic performance in training or competition. Complete data was collected and analyzed for 88 athletes; among t1xbet 온라인 subjects, 73 (83%) were high-level athletes who had participated in national or international competition.
T1xbet 온라인 prevalence of equol producers was 29.5%, similar to t1xbet 온라인 low prevalence (20.6%) among young women in general. Awareness of interference in athletic performance due to PMS was cited by 48 subjects (54.5%). Equol non-producers showed a 3.3-times risk factor for PMS-induced performance decline. Restriction of bodyweight was also associated with an increased risk (4.9-times) of poor athletic performance, indicating t1xbet 온라인 importance of balanced nutrition.

This research was undertaken as an intervention study on prevention of young women's sports injuries, supported by grants from t1xbet 온라인 Japan Agency for Medical Research and Development (AMED) as part of t1xbet 온라인 Project for Whole Implementation to Support and Ensure t1xbet 온라인 Female Life.
