The authors aimed to quantify (a) the periodization of physical loading and daily carbohydrate (CHO) intake across an in-season weekly microcycle of Australian Football and (b) the quantity and source of CHO consumed during game play and training. Physical loading (via global positioning system technology) and daily CHO intake (via a combination of 24-hr recall, food diaries, and remote food photographic method) were assessed in 42 professional male players during two weekly microcycles comprising a home and away fixture. The players also reported the source and quantity of CHO consumed during all games (n = 22 games) and on the training session completed 4 days before each game (n = 22 sessions). The total distance was greater (p < .05) on game day (GD; 13 km) versus all training days. The total distance differed between training days, where GD-2 (8 km) was higher than GD-1, GD-3, and GD-4 (3.5, 0, and 7 km, respectively). The daily CHO intake was also different between training days, with reported intakes of 1.8, 1.4, 2.5, and 4.5 g/kg body mass on GD-4, GD-3, GD-2, and GD-1, respectively. The CHO intake was greater (p < .05) during games (59 ± 19 g) compared with training (1 ± 1 g), where in the former, 75% of the CHO consumed was from fluids as opposed to gels. Although the data suggest that Australian Football players practice elements of CHO periodization, the low absolute CHO intakes likely represent considerable underreporting in this population. Even when accounting for potential underreporting, the data also suggest Australian Football players underconsume CHO in relation to the physical demands of training and competition.

作者的目的是量化 (a) 澳式足球赛季中每周微周期的身体负荷和每日碳水化合物 (CHO) 摄入量的周期，以及 (b) 比赛和训练期间消耗的 CHO 的数量和来源。在包括主客场比赛在内的每周两周的微周期中，对 42 名职业男性球员的身体负荷（通过全球定位系统技术）和每日 CHO 摄入量（通过 24 小时回忆、食物日记和远程食物摄影方法相结合）进行了评估。球员还报告了所有比赛（ n = 22 场比赛）以及每场比赛前 4 天完成的训练（ n = 22 场比赛）期间消耗的 CHO 来源和数量。与所有训练日相比，比赛日（GD；13 公里）的总距离更大 ( p < .05)。训练日之间的总距离有所不同，其中 GD-2（8 公里）高于 GD-1、GD-3 和 GD-4（分别为 3.5、0 和 7 公里）。训练日之间每日 CHO 摄入量也不同，据报告，GD-4、GD-3、GD-2 和 GD-1 的摄入量分别为 1.8、1.4、2.5 和 4.5 g/kg 体重。与训练期间 (1 ± 1 g) 相比，比赛期间的 CHO 摄入量 (59 ± 19 g) 更高 ( p < .05)，其中消耗的 CHO 的 75% 来自液体而不是凝胶。尽管数据表明澳大利亚足球运动员练习 CHO 周期化的元素，但 CHO 绝对摄入量较低可能代表该人群的漏报情况相当严重。即使考虑到潜在的漏报，数据也表明澳大利亚足球运动员在训练和比赛的身体需求方面摄入的 CHO 不足。
