Knowledge gaps, sleep disturbances, and energy imbalance among female field hockey players. Nutrients, 17(24), 3934. https://doi.org/10.3390/nu172439342072-6643https://hdl.handle.net/11268/16679Field hockey is a high-intensity intermittent sport, where nutrition and sleep play an important role in the performance and health of all players, especially in women, who often exhibit a dietary pattern characterized by low energy and carbohydrate intake, along with poor nighttime habits. The purpose of this study is to evaluate the profile of female field hockey players by analyzing their energy and macronutrient intake, prevalence of LEA risk, use of SS, and sleep characteristics. A cross-sectional, observational, and descriptive study was carried out with 75 female players. Validated questionnaires were used to determine general sports nutrition knowledge (NUKYA) and specific knowledge of carbohydrates in sports (CEAC-Q), sleep quality (ASSQ), low energy availability risk (LEAF-Q), and use of sport supplements. In addition, a 7-day dietary record was analyzed.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/HockeyCiencias de la nutrición y del deporteCalidad del sueñojournal article10.3390/nu17243934open accessDeporteNutriciónDietéticaGoal 3: Ensure healthy lives and promote well-being for all at all ages
