Brief summary
This is an observational study aiming to assess the nutritional knowledge, dietary habits, supplement use, body composition, and physiological profiles of HYROX athletes. The main objective is to describe and evaluate the nutritional, anthropometric, and performance-related characteristics of these athletes to better understand factors influencing race performance. The main question it seeks to answer is: What are the nutritional, kinanthropometric, and physiological profiles of HYROX athletes, and how are dietary practices, supplement use, and body composition associated with their performance?
Detailed description
HYROX athletes represent a unique cohort characterized by specific nutritional, physiological, and multi-modal performance demands, including body composition, strength, and endurance. 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. Data 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. By synthesizing these metrics, the study establishes a foundational characterization of the hybrid athlete, identifying physiological risks and providing the evidence-based framework necessary to optimize competitive performance

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dietary intake | 5 years | A validated Short Food Frequency Questionnaire (SFFFQ) will be used to assess dietary quality. The questionnaire consists of 20 items covering key food groups, including fruits, vegetables, high-fiber foods, high-fat and sugary foods, meat and meat products, and fish. Participants are asked to report the frequency of foods and beverages consumed during a "typical week" over the past month. Response options range from "rarely or never" to "more than five times per day." The final score will be calculated based on the extent to which participants meet the UK dietary recommendations. |

| Measure | Time frame | Description |
|---|---|---|
| Body composition | 5 years | Assess body composition by anthropometry to estimate muscle mass and fat mass |
