Professional rugby league (RL) football is a contact sport involving repeated collisions and high-intensity efforts; both training and competition involve high energy expenditure. The present review summarizes and critiques the available literature relating the physiological demands of RL to nutritional requirements and considers potential ergogenic supplements that could improve players’ physical capacity, health, and recovery during the preparatory and competition phases of a season. Although there may not be enough data to provide RL-specific recommendations, the available data suggest that players may require approximately 6–8 g·kg⁻¹·day⁻¹ carbohydrate, 1.6–2.6 g·kg⁻¹·day⁻¹ protein, and 0.7–2.2 g·kg⁻¹·day⁻¹ fat, provided that the latter also falls within 20–35% of total energy intake. Competition nutrition should maximize glycogen availability by consuming 1–4 g/kg carbohydrate (∼80–320 g) plus 0.25 g/kg (∼20–30 g) protein, 1–4 hr preexercise for 80–120 kg players. Carbohydrate intakes of approximately 80–180 g (1.0–1.5 g/kg) plus 20–67 g protein (0.25–0.55 g/kg) 0–2 hr postexercise will optimize glycogen resynthesis and muscle protein synthesis. Supplements that potentially improve performance, recovery, and adaptation include low to moderate dosages of caffeine (3–6 mg/kg) and ∼300 mg polyphenols consumed ∼1 hr preexercise, creatine monohydrate “loading” (0.3 g·kg⁻¹·day⁻¹) and/or maintenance (3–5 g/day), and beta-alanine (65–80 mg·kg⁻¹·day⁻¹). Future research should quantify energy expenditures in young, professional male RL players before constructing recommendations.

职业橄榄球联盟（RL）足球是一项涉及反复碰撞和高强度努力的接触运动；训练和比赛都涉及高能量消耗。本综述总结并批评了现有文献，将强化学习的生理需求与营养需求相关联，并考虑了潜在的增能补充剂，这些补充剂可以提高球员在赛季准备和比赛阶段的体能、健康和恢复。尽管可能没有足够的数据来提供针对 RL 的建议，但现有数据表明，球员可能需要大约 6-8 g·kg ^-1 ·day ^-1碳水化合物，1.6-2.6 g·kg ^-1 ·day ^-1蛋白质, 和 0.7–2.2 g·kg ^-1·day ^-1脂肪，前提是后者也在总能量摄入的 20-35% 范围内。比赛营养应通过消耗 1-4 g/kg 碳水化合物（~80-320 g）加上 0.25 g/kg（~20-30 g）蛋白质，为 80-120 kg 运动员进行 1-4 小时的运动前摄入，从而最大限度地提高糖原的利用率。运动后 0-2 小时摄入约 80-180 g (1.0-1.5 g/kg) 和 20-67 g 蛋白质 (0.25-0.55 g/kg) 的碳水化合物将优化糖原再合成和肌肉蛋白质合成。可能提高运动表现、恢复和适应能力的补充剂包括低至中等剂量的咖啡因（3–6 mg/kg）和运动前 ∼1 小时消耗的 ∼300 mg 多酚，一水肌酸“负荷”（0.3 g·kg ^-1 ·day ^-1 ) 和/或维持 (3–5 g/天)，和 β-丙氨酸 (65–80 mg·kg ^-1·天^-1 )。未来的研究应该在构建建议之前量化年轻、专业的男性 RL 玩家的能量消耗。
