The goal of this study was to review data on physical activity level (PAL), a crucial index for determining estimated energy requirement (EER), calculated as total energy expenditure (TEE, assessed with doubly labeled water [DLW]) divided by resting metabolic rate (RMR, PAL = TEE/RMR) in female athletes and to understand the methods of assessing athletes' EERs in the field.
For the PAL data review among female athletes, we conducted a PubMed search of the available literature related to the DLW method. DLW studies measuring TEE and RMR were included for the present review.
Briefly, the mean PAL was 1.71 for collegiate swimmers with moderate training, which was relatively low, but the mean PAL was 3.0 for elite swimmers during summer training camp. This shows that PAL can largely vary even within the same sport depending on the amount of training, and the differences in PAL were remarkable depending on the sport. Aside from the DLW method, there is currently no research tool related to athletes' EERs that can be used in the field.

本研究的目的是回顾关于身体活动水平（PAL）的数据，PAL是确定估计能量需求（EER）的关键指标，通过总能量消耗（TEE，用双标水[DLW]评估）除以静息代谢率（RMR，PAL = TEE/RMR）来计算，本研究旨在回顾女性运动员的相关数据，并了解在实际应用中评估运动员EER的方法。
为了回顾女性运动员的PAL数据，我们在PubMed上搜索了与DLW方法相关的现有文献。本综述纳入了测量TEE和RMR的DLW研究。
简而言之，中等训练强度的大学游泳运动员的平均PAL为1.71，相对较低，但在夏季训练营期间，精英游泳运动员的平均PAL为3.0。这表明，即使在同一项运动中，PAL也会因训练量的不同而有很大差异，并且不同运动项目之间PAL的差异也很显著。除了DLW方法外，目前尚无适用于实际应用的、与运动员EER相关的研究工具。
