In professional rugby union, it is common for players to switch between catered and non-catered dietary environments throughout a season. However, little is known about the difference in dietary intake between these two settings. Twelve elite male professional rugby union players (28.3 ± 2.9 y, 188.9 ± 9.5 cm, 104.1 ± 13.3 kg) from the New Zealand Super Rugby Championship completed seven-day photographic food diaries with two-way communication during two seven-day competition weeks in both catered and non-catered environments. While no significant differences were observed in relative carbohydrate intake, mean seven-day absolute energy intakes (5210 ± 674 vs. 4341 ± 654 kcal·day), relative protein (2.8 ± 0.3 vs. 2.3 ± 0.3 g·kgBM·day) and relative fat (2.1 ± 0.3 vs. 1.5 ± 0.3 g·kgBM·day) intakes were significantly higher in the catered compared to the non-catered environment (respectively) among forwards ( = 6). Backs ( = 6) presented non-significantly higher energy and macronutrient intakes within a catered compared to a non-catered environment. More similar dietary intakes were observed among backs regardless of the catering environment. Forwards may require more support and/or attention when transitioning between catered and non-catered environments to ensure that recommended dietary intakes are being achieved.
在职业橄榄球联盟中，球员在整个赛季中经常在有餐饮和无餐饮的环境之间切换。然而，对于这两种环境下的饮食摄入差异知之甚少。12 名来自新西兰超级橄榄球锦标赛的精英男性职业橄榄球联盟球员（28.3±2.9 岁，188.9±9.5 厘米，104.1±13.3 公斤）在有餐饮和无餐饮的环境中完成了为期 7 天的摄影食物日记，并在两个 7 天的比赛周内进行了双向沟通。虽然在相对碳水化合物摄入方面没有观察到显著差异，但在有餐饮的环境中，平均 7 天的绝对能量摄入量（5210±674 千卡/天）、相对蛋白质摄入量（2.8±0.3 克/公斤 BM/天）和相对脂肪摄入量（2.1±0.3 克/公斤 BM/天）明显高于无餐饮环境（分别为 6）。在有餐饮的环境中，前锋的能量和宏量营养素摄入量明显高于无餐饮环境（6）。在有餐饮的环境中，后卫的能量和宏量营养素摄入量明显高于无餐饮环境，但差异无统计学意义（6）。无论餐饮环境如何，后卫的饮食摄入更为相似。在从有餐饮和无餐饮的环境之间转换时，前锋可能需要更多的支持和/或关注，以确保达到推荐的饮食摄入量。
