Prior studies have examined offshore sailing and energy strategies using accurate total energy expenditure (TEE) measurement in free-living conditions. However, no research has studied energy and water requirement during dinghy class sailing such as an Olympic event with concentrated training. This study aimed to investigate the TEE, physical activity level (PAL), and water turnover (rH2O) of collegiate dinghy sailors in a training camp using the doubly labeled water (DLW) method. Eleven dinghy sailing collegiate athletes (9 males and 2 females) participated. The DLW method was used to determine the participants' TEE and PAL over 8 days (6 training, 2 non-training days). Participants trained approximately 7 h/day on water. Body fat was measured using a stable-isotope dilution method. The rH2O was estimated using deuterium turnover. The mean TEE, PAL, and rH2O were 17.30 ± 4.22 MJ/day (4133 ± 1009 kcal/day), 2.8 ± 0.3 (range, 2.1 to 4.1), and 3.3±0.7 (range, 2.6 to 4.5) L/day, respectively. To our knowledge, this was the first study to use the DLW method to determine TEE, PAL, and rH2O as references for competitive dinghy sailors in a spring training camp. Our results may serve as a reference to assist competitive dinghy sailors in determining their required nutritional support.

在训练营中的小艇水手的总能量消耗，体育活动水平和水流失。

先前的研究已经通过在自由生活条件下使用精确的总能源消耗（TEE）测量来研究海上航行和能源策略。但是，尚无研究研究充气小艇航行过程中的能量和水需求，例如经过集中训练的奥林匹克比赛。这项研究的目的是使用双重标记水（DLW）方法调查训练营中的大学小艇水手的TEE，体力活动水平（PAL）和水周转率（rH2O）。参加了11名小艇帆船运动的大学运动员（男9名，女2名）。DLW方法用于确定参与者在8天（6个训练，2个非训练天）中的TEE和PAL。参加者每天大约接受7个小时的水上训练。使用稳定同位素稀释法测量人体脂肪。rH2O使用氘转化率估算。平均TEE，PAL和rH2O为17.30±4.22 MJ /天（4133±1009 kcal /天），2.8±0.3（范围2.1至4.1）和3.3±0.7（范围2.6至4.5）L /天，分别。据我们所知，这是第一个使用DLW方法确定TEE，PAL和rH2O的研究，作为春季训练营中竞争性小艇水手的参考。我们的结果可作为参考，以帮助竞争性小艇水手确定所需的营养支持。
