关于身体状况是否会影响重力引起的意识丧失（G-Loss）的风险尚未达成共识，并且大多数以前关于这个问题的研究都没有包括经验丰富的飞行员。我们根据人体离心机训练中G-β的发生情况，比较了经验丰富的年轻飞行员的身体状况。在361名现役男性飞行员中，有至少2年的高性能飞机经验，350人有完整的数据，并在这项研究中进行了审查。根据人体离心机训练结果，将飞行员分为加氧组和非加氧组。然后比较他们的基本特征、身体成分、体能水平和肺功能。29名飞行员（8.3%）在首次试验中经历了人体离心机训练中的G-肌张力，被归类为G-肌张力组。两组飞行员的身体状况无差异。有飞行经验的年轻飞行员在肌肉质量、力量和一般耐力等身体状况方面与没有飞行经验的飞行员没有差异。虽然需要更多的研究，身体状况似乎并不是一个显着的决定因素，G-肌张力之间的经验丰富的飞行员。
Consensus on whether physical condition affects the risk of gravity-induced loss of consciousness (G-LOC) has not been reached, and most previous studies about the issue did not include well-experienced aviators. We compared the physical conditions of well-experienced young aviators according to the occurrence of G-LOC during human centrifuge training. Among 361 young male aviators on active flight duty with experience in high performance aircrafts for at least 2 years, 350 had full data available and were reviewed in this study. We divided the aviators into the G-LOC group and the non-G-LOC group according to their human centrifuge training results. We then compared their basic characteristics, body composition, physical fitness level, and pulmonary function. Twenty nine aviators (8.3%) who experienced G-LOC during human centrifuge training in their first trials were classified into the G-LOC group. There was no difference in physical condition of aviators between the two groups. Young aviators with experience in G-LOC showed no difference in physical condition such as muscle mass, strength, and general endurance from the aviators with no such experience. Although more studies are needed, physical condition does not seem to be a significant determinant of G-LOC among the experienced aviators.
