UNASSIGNED: Results, Conclusions Six male, elite-standard archers participated in the study and measurements of hydration status, EI, competition load, and sleep were recorded throughout each day of competition.
UNASSIGNED: Daily energy, carbohydrate, and protein intake ranged between 2,563 and 3,986 kcal, 4 and 7.1 g/kg BM, 2.2 and 3.6 g/kg BM per day, respectively. Thus, archers practiced elements of periodized nutrition such that energy and carbohydrate intake was greater on the high-volume competition days (i.e. days 1 and 3; more numbers of arrows, longer duration, and walking distance) in comparison to low-volume days (days 2 and 4) over the tournament (all p > 0.01). Additionally, urine specific gravity was higher after waking, compared to pre- and post-competition, and before bed (all p < 0.05). This indicates that archers were euhydrated pre- and post-competition and before bedtime, while they were slightly hypohydrated after waking up. Sleep data show that disturbances were kept to a minimum.
UNASSIGNED: Collectively, archers appear capable of periodizing their nutritional intake according to daily physical loading during a tournament whilst, staying euhydrated and maintaining sleep quality. In part, such data can help to explain why these archers experience a sustained level of success.
■结果,结论六位男性,精英标准弓箭手参与了水化状态的研究和测量,EI,竞争负荷,在比赛的每一天都记录睡眠。
■每日能量,碳水化合物,蛋白质摄入量在2,563和3,986千卡之间,4和7.1g/kgBM,每天2.2和3.6g/kgBM,分别。因此,弓箭手练习周期营养元素,以便在高容量比赛日(即第1天和第3天;更多数量的箭头,持续时间较长,和步行距离)与比赛中的低容量天数(第2天和第4天)相比(所有p>0.01)。此外,醒来后尿液比重更高,与赛前和赛后相比,和睡前(所有p<0.05)。这表明弓箭手在比赛前和比赛后以及就寝时间之前都是均衡的,而他们醒来后有点水分不足。睡眠数据显示干扰保持在最低限度。
■集体,弓箭手似乎能够根据比赛期间的日常身体负荷来改变他们的营养摄入量,保持水分充足,保持睡眠质量。在某种程度上,这些数据可以帮助解释为什么这些弓箭手经历了持续的成功水平。
