The EAT-26 comprises three subscales: Diet, Bulimia, and Oral Control, with responses on a 5-point Likert scale from 1 (Never) to 5 (Always). It also includes five questions related to disordered eating behaviors to identify athletes at risk, with a score of 20 or more suggesting possible eating disorders.

Each correct answer is awarded +1 point, while each incorrect answer is assigned -1 point. The maximum possible score is 59 points, and the minimum possible score (all answers incorrect) is -59 points.

Despite the global growth of hybrid fitness competitions, empirical evidence regarding the dietary practices, nutritional knowledge, and body composition of these athletes remains limited. This study addresses this gap through a comprehensive cross-sectional assessment of competitive HYROX athletes.\n\nData were collected using validated online questionnaires, including a Short Food Frequency Questionnaire (SFFFQ) to evaluate dietary intake, a 20-item supplement use questionnaire assessing consumption patterns, beliefs, and knowledge, and the Abbreviated Nutrition for Sport Knowledge Questionnaire (A-NSKQ) to measure nutritional knowledge. Eating behaviors and potential disordered eating were screened using the EAT-26 and the Figure Rating Scale (FRS). This structured protocol enables a detailed characterization of dietary habits, supplementation practices, nutritional knowledge, and body composition among HYROX athletes.
