• Study to determine relation between PMS-induced interference in athletic performance 1xbet 온라인 equol production status
• Indicates the importance 1xbet 온라인 equol production status and adequate intake 1xbet 온라인 nutrients for overcoming PMS-induced performance interference
• Supplementation 1xbet 온라인 equol may be beneficial for improving female athletic performance

Summary

Equol is a biologically active substance metabolized in the human body from a soy is1xbet 온라인lavone. Due to the presence 1xbet 온라인 specific intestinal bacteria, some individuals are able to produce equol while others are non-producers. Previous research has indicated that approximately 42% 1xbet 온라인 reproductive-aged Japanese women are equol producers^*1; equol non-producers show more than twice the risk 1xbet 온라인 PMS/PMDD^*2.
To investigate the 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 higher risk 1xbet 온라인 PMS-induced performance interference. Restriction 1xbet 온라인 bodyweight is also a risk factor for PMS-induced performance interference, indicating the importance 1xbet 온라인 adequate intake 1xbet 온라인 nutrients in addition to equol production status. New methods 1xbet 온라인 alleviating PMS/PMDD through supplementation 1xbet 온라인 equol may enable female athletes to perform at their best.

In 2014, the Kindai University Research Institute 1xbet 온라인 Traditional Asian Medicine reported that 44.3% 1xbet 온라인 female athletes affiliated with university sports clubs indicated negative effects 1xbet 온라인 premenstrual symptoms on performance in training or competition^*3. It has also been clarified that equol producers show a lower risk 1xbet 온라인 developing menopausal disorders, osteoporosis, cardiovascular disease and other estrogen-related diseases. Joint research conducted by the Kindai University Research Institute 1xbet 온라인 Traditional Asian Medicine and Otsuka Pharmaceutical in 2016 showed that equol non-producers had a 2.4-times higher risk 1xbet 온라인 PMS/PMDD^*1.

Details 1xbet 온라인 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 1xbet 온라인 complete a questionnaire regarding PMS-related interference with athletic performance in training or competition. Complete data was collected 1xbet 온라인 analyzed for 88 athletes; among the subjects, 73 (83%) were high-level athletes who had participated in national or international competition.
The prevalence 1xbet 온라인 equol producers was 29.5%, similar to the low prevalence (20.6%) among young women in general. Awareness 1xbet 온라인 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 1xbet 온라인 bodyweight was also associated with an increased risk (4.9-times) 1xbet 온라인 poor athletic performance, indicating the importance 1xbet 온라인 balanced nutrition.
