估计能量需求（EERs）对基于体重分类的运动很重要，有助于体重管理。建立EERs的基础各不相同，包括自我报告的能量摄入（EI）、预测的能量消耗和测量的每日能量消耗。然而，目前还没有对男性摔跤运动员进行研究，使用高度准确和精确的双标记水（DLW）方法来估计能量和液体需求。本研究的主要目的是使用DLW方法比较大学摔跤运动员在正常训练期间的总能量消耗（TEE）、自我报告的EI和差异。次要目的是测量运动员的水分周转量和身体活动水平（PAL），并检验目前用于预测EER的两个方程的准确性。10名来自东日本大学联盟的健康男性（年龄，20.4±0.5岁）参与了本研究。TEE采用DLW法测量，EI采用约1周的自我报告饮食记录进行评估。TEE (17.9 +/- 2.5 MJ中心dot d（-1) [4,283 +/- 590 kcal中心dot d(-1)]）与自我报告EI (14.4 +/- 3.3 MJ中心dot d（-1) [3,446 +/- 799 kcal中心dot d(-1)]）之间差异显著，差异为19%。水分周转量为4.61±0.73 L中心点d（-1）。在训练季节，实测PAL（2.6 +/- 0.3）高于两个预测值，因此两个EER预测方程相对于DLW产生了低估的值。我们发现以前的EERs低估了大学摔跤运动员的需求，这些估计应该被修改。
Estimated energy requirements (EERs) are important for sports based on body weight classifications to aid in weight management. The basis for establishing EERs varies and includes self-reported energy intake (EI), predicted energy expenditure, and measured daily energy expenditure. Currently, however, no studies have been performed with male wrestlers using the highly accurate and precise doubly labeled water (DLW) method to estimate energy and fluid requirement. The primary aim of this study was to compare total energy expenditure (TEE), self-reported EI, and the difference in collegiate wrestlers during a normal training period using the DLW method. The secondary aims were to measure the water turnover and the physical activity level (PAL) of the athletes, and to examine the accuracy of two currently used equations to predict EER. Ten healthy males (age, 20.4 +/- 0.5 y) belonging to the East-Japan college league participated in this study. TEE was measured using the DLW method, and EI was assessed with self-reported dietary records for similar to 1 wk. There was a significant difference between TEE (17.9 +/- 2.5 MJ center dot d(-1) [4,283 +/- 590 kcal center dot d(-1)]) and self-reported EI (14.4 +/- 3.3 MJ center dot d(-1) [3,446 +/- 799 kcal center dot d(-1)]), a difference of 19%. The water turnover was 4.61 +/- 0.73 L center dot d(-1). The measured PAL (2.6 +/- 0.3) was higher than two predicted values during the training season and thus the two EER prediction equations produced underestimated values relative to DLW. We found that previous EERs were underestimating requirements in collegiate wrestlers and that those estimates should be revised.
