Training Habits of Eumenorrheic Active Women during the Different Phases of Their Menstrual Cycle: A Descriptive Study García Pinillos, Felipe Gender Training Load Health surveys Sport participation This research was supported by the Pre-competitive Projects for Early Stage Researchers Program from the University of Granada (ref: PPJIA2020.03). The authors would like to thank all the participants. This study meets the ethical standards of theWorld Medical Association’s Declaration of Helsinki (2013), and it was approved by the Institutional Review Board (Universidad de La Frontera, Temucho, Chile, 005_19). Informed consent was obtained from all subjects involved in the study. The purpose of this study was to examine the training habits of eumenorrheic active women during their menstrual cycle (MC), and its perceived influence on physical performance regarding their athletic level. A group of 1250 sportswomen filled in a questionnaire referring to demographic information, athletic performance and MC-related training habits. Of the participants, 81% reported having a stable duration of MC, with most of them (57%) lasting 26-30 days. Concerning MC-related training habits, 79% indicated that their MC affects athletic performance, although 71% did not consider their MC in their training program, with no differences or modifications in training volume or in training intensity for low-level athletes (LLA) and high-level athletes (HLA) with hormonal contraceptive (HC) use. However, LLA with a normal MC adapted their training habits more, compared with HLA, also stopping their training (47.1% vs. 16.1%, respectively). Thus, different training strategies should be designed for HLA and LLA with a normal MC, but this is not so necessary for HLA and LLA who use HC. To sum up, training adaptations should be individually designed according to the training level and use or non-use of HC, always taking into account the pain suffered during the menstrual phase in most of the athletes. 2021-05-03T10:26:19Z 2021-05-03T10:26:19Z 2021-04-01 info:eu-repo/semantics/article García-Pinillos, F.; Bujalance-Moreno, P.; Jérez-Mayorga, D.; Velarde-Sotres, Á.; Anaya-Moix, V.; Pueyo-Villa, S.; Lago-Fuentes, C.
