BackgroundBritish Army Phase One training exposes men and women to challenging distances of 13.5 km·d− 1 vs. 11.8 km·d− 1 and energy expenditures of ~ 4000 kcal·d− 1 and ~ 3000 kcal·d− 1, respectively. As such, it is essential that adequate nutrition is provided to support training demands. However, to date, there is a paucity of data on habitual dietary intake of British Army recruits. The aims of this study were to: (i) compare habitual dietary intake in British Army recruits undergoing Phase One training to Military Dietary Reference Values (MDRVs), and (ii) establish if there was a relative sex difference in dietary intake between men and women.MethodResearcher led weighed food records and food diaries were used to assess dietary intake in twenty-eight women (age 21.4 ± 3.0 yrs., height: 163.7 ± 5.0 cm, body mass 65.0 ± 6.7 kg), and seventeen men (age 20.4 ± 2.3 yrs., height: 178.0 ± 7.9 cm, body mass 74.6 ± 8.1 kg) at the Army Training Centre, Pirbright for 8-days in week ten of training. Macro and micronutrient content were estimated using dietary analysis software (Nutritics, Dublin) and assessed via an independent sample t-test to establish if there was a sex difference in daily energy, macro or micronutrient intakes.ResultsEstimated daily energy intake was less than the MDRV for both men and women, with men consuming a greater amount of energy compared with women (2846 ± 573 vs. 2207 ± 585 kcal·day− 1, p < 0.001). Both sexes under consumed carbohydrate (CHO) when data was expressed relative to body mass with men consuming a greater amount than women (4.8 ± 1.3 vs. 3.8 ± 1.4 g·kg− 1·day− 1, p = 0.025, ES = 0.74). Both sexes also failed to meet MDRVs for protein intake with men consuming more than women (1.5 ± 0.3 vs. 1.3 ± 0.3 g·kg− 1·day− 1, p > 0.030, ES = 0.67). There were no differences in dietary fat intake between men and women (1.5 ± 0.2 vs. 1.5 ± 0.5 g·kg− 1·day− 1, p = 0.483, ES = 0.00).ConclusionsDaily EI in men and women in Phase One training does not meet MDRVs. Interventions to increase macronutrient intakes should be considered along with research investigating the potential benefits for increasing different macronutrient intakes on training adaptations.

接受第一阶段训练的英国陆军新兵饮食摄入的性别差异

背景英国陆军第一阶段训练使男性和女性分别面临 13.5 km·d− 1 和 11.8 km·d− 1 的挑战性距离以及~ 4000 kcal·d− 1 和~ 3000 kcal·d− 1 的能量消耗。因此，必须提供足够的营养来支持培训需求。然而，迄今为止，关于英国陆军新兵习惯性饮食摄入量的数据很少。本研究的目的是：(i) 将接受第一阶段训练的英国陆军新兵的习惯性饮食摄入量与军事饮食参考值 (MDRV) 进行比较，以及 (ii) 确定男性和女性的饮食摄入量是否存在相对性别差异。女性。方法研究人员采用称重食物记录和食物日记来评估 28 名女性（年龄 21.4 ± 3.0 岁，身高：163.7 ± 5.0 cm，体重 65.0 ± 6.7 kg）的膳食摄入量，和 17 名男性（年龄 20.4 ± 2.3 岁，身高：178.0 ± 7.9 厘米，体重 74.6 ± 8.1 公斤）在皮尔布莱特陆军训练中心进行了为期 8 天的训练。使用膳食分析软件 (Nutritics, Dublin) 估计宏量和微量营养素含量，并通过独立样本 t 检验进行评估，以确定每日能量、宏量或微量营养素摄入量是否存在性别差异。 结果估计的每日能量摄入量低于 MDRV对于男性和女性，男性比女性消耗更多的能量（2846 ± 573 vs. 2207 ± 585 kcal·day− 1, p < 0.001）。当数据相对于体重表示男性消耗量比女性多（4.8 ± 1.3 对 3.8 ± 1.4 g·kg− 1·day− 1，p = 0.025，ES = 0.74）时，两性均摄入碳水化合物 (CHO) ）。两性也未能满足蛋白质摄入量的 MDRV，男性比女性摄入更多（1.5 ± 0.3 与 1.3 ± 0.3 g·kg− 1·day− 1，p > 0.030，ES = 0.67）。男性和女性的膳食脂肪摄入量没有差异（1.5 ± 0.2 vs. 1.5 ± 0.5 g·kg− 1·day− 1, p = 0.483, ES = 0.00）。结论 第一阶段训练中男性和女性的每日 EI不符合 MDRV。增加常量营养素摄入量的干预措施应与调查增加不同常量营养素摄入量对训练适应的潜在益处的研究一起考虑。结论 第一阶段训练中男性和女性的每日 EI 不符合 MDRV。增加常量营养素摄入量的干预措施应与调查增加不同常量营养素摄入量对训练适应的潜在益处的研究一起考虑。结论 第一阶段训练中男性和女性的每日 EI 不符合 MDRV。增加常量营养素摄入量的干预措施应与调查增加不同常量营养素摄入量对训练适应的潜在益处的研究一起考虑。
