Original abstract
<h4>Background</h4>Adequate nutrition knowledge (NK) and dietary intake are important to the development in Youth Development Phase (YDP) academy footballers, helping to fuel sporting performance and promote long-term health. However, these areas remain under-researched within English Premier League (EPL) academy settings. This study aimed to investigate NK and energy intake (EI) in YDP academy players, including key stakeholders' knowledge, within a single Category 1 Academy.<h4>Methods</h4>Eighty-three EPL Category 1 YDP academy players (U11s = 17, U12s = 16, U13s = 8, U14s = 17, U15s = 10, and U16s = 15; 14 ± 2 years), 6 academy coaches, 1 YDP sports scientist and 31 caregivers' knowledge was assessed through the 89-item Knowledge and Sports Questionnaire (NSKQ). Twenty-five EPL Category 1 YDP academy players (U12s: <i>n</i> = 8, U13s: <i>n</i> = 9, U14s: <i>n</i> = 5, and U16s: <i>n</i> = 3; 13 ± 2 years) dietary intake was also assessed using an estimated written 7-day food diary collected during the in-season (2023/2024 season, March to May 2023).<h4>Results</h4>Collectively, academy players (33% ± 8%), caregivers (40% ± 13%), and coaches (41% ± 9%) scored poorly on NK. Academy players reported sub-optimal energy intake (1742 ± 314 kcal·day<sup>-1</sup> and 38.5 ± 11.4 kcal·kg⁻¹·day⁻¹), accompanied by poor intake of daily carbohydrate (<5 g·kg-1·d<sup>-1</sup>), and fiber (<25 g/day) referenced to recommended daily intakes. Daily protein intake (1.7 ± 0.5 g·kg-1·d<sup>-1</sup>) exceeded the recommended intake for adolescent footballers, while fat intake (27% ± 6%) expressed as a percentage of total dietary intake (TDI) was within the guidelines. NK was not correlated with absolute EI, (<i>r</i>(23) = -.187, <i>p</i> = .371, or EI adjusted to BM, (<i>r</i>(23) = .204, <i>p</i> = .329.<h4>Conclusion</h4>The results indicated poor NK and suboptimal dietary intake in EPL Category 1 academy players accompanied by low knowledge among stakeholders.
