The nutritional status of elite soccer players across match, postmatch, training and rest days has not been defined. Recent evidence suggests the pattern of dietary protein intake impacts the daytime turnover of muscle proteins and, as such, influences muscle recovery. We assessed the nutritional status and daytime pattern of protein intake in senior professional and elite youth soccer players and compared findings against published recommendations. Fourteen senior professional (SP) and 15 youth elite (YP) soccer players from the Dutch premier division completed nutritional assessments using a 24-hr web-based recall method. Recall days consisted of a match, postmatch, rest, and training day. Daily energy intake over the 4-day period was similar between SP (2988 ± 583 kcal/day) and YP (2938 ± 465 kcal/day; p = .800). Carbohydrate intake over the combined 4-day period was lower in SP (4.7 ± 0.7 g·kg-1 BM·day-1) vs. YP (6.0 ± 1.5 g·kg-1 BM·day-1, p = .006) and SP failed to meet recommended carbohydrate intakes on match and training days. Conversely, recommended protein intakes were met for SP (1.9 ± 0.3 g·kg-1 BM·day-1) and YP (1.7 ± 0.4 g·kg-1 BM·day-1), with no differences between groups (p = .286). Accordingly, both groups met or exceeded recommended daily protein intakes on individual match, postmatch, rest and training days. A similar "balanced" daytime pattern of protein intake was observed in SP and YP. To conclude, SP increased protein intake on match and training days to a greater extent than YP, however at the expense of carbohydrate intake. The daytime distribution of protein intake for YP and SP aligned with current recommendations of a balanced protein meal pattern.
精英足球运动员在比赛日、赛后、训练日和休息日的营养状况尚未明确。最近的证据表明,膳食蛋白质摄入模式会影响肌肉蛋白质的日间周转率,进而影响肌肉恢复。我们评估了高级职业和精英青年足球运动员的营养状况以及蛋白质摄入的日间模式,并将结果与已发表的建议进行了比较。来自荷兰顶级联赛的14名高级职业(SP)足球运动员和15名青年精英(YP)足球运动员使用基于网络的24小时回忆法完成了营养评估。回忆日包括比赛日、赛后日、休息日和训练日。SP组(2988±583千卡/天)和YP组(2938±465千卡/天;p = 0.800)在4天期间的每日能量摄入量相似。在合并的4天期间,SP组的碳水化合物摄入量(4.7±0.7克·千克-1体重·天-1)低于YP组(6.0±1.5克·千克-1体重·天-1,p = 0.006),并且SP组在比赛日和训练日未达到推荐的碳水化合物摄入量。相反,SP组(1.9±0.3克·千克-1体重·天-1)和YP组(1.7±0.4克·千克-1体重·天-1)均达到了推荐的蛋白质摄入量,两组之间无差异(p = 0.286)。因此,两组在各自的比赛日、赛后日、休息日和训练日都达到或超过了推荐的每日蛋白质摄入量。在SP组和YP组中观察到了相似的蛋白质摄入“均衡”日间模式。总之,SP组在比赛日和训练日比YP组更大程度地增加了蛋白质摄入量,但以碳水化合物摄入量为代价。YP组和SP组蛋白质摄入的日间分布与当前关于均衡蛋白质膳食模式的建议一致。
