To our knowledge, this is the first study to use MRI (Magnetic Resonance Imaging) before and after an intensive flight training. This study aimed to investigate the effectiveness of flight training in civil flying cadets.
The civil flying cadets and controls completed two study visits. Visit 1 was performed in 2019, and high spatial resolution structural image and resting-state functional MRI data were collected. The second visit was completed in 2022. In addition to the MRI data mentioned above, participants completed the cognitive function assessment at the second visit.
Mixed-effect regression model analysis found that flight training enhanced the degree centrality (DC) values of the left middle frontal gyrus and left lingual gyrus. The subsequent correlation calculation analysis suggested a possible relationship between these alterations and cognitive function.
These results suggest that flight training might promote the DC value of the prefrontal and occipital cortices and, in turn, enhance their executive function.
据我们所知，这是第一项在高强度飞行训练前后使用磁共振成像（MRI）的研究。本研究旨在调查飞行训练对民用飞行学员的有效性。
民用飞行学员和对照组完成了两次研究访问。第一次访问于2019年进行，收集了高空间分辨率结构图像和静息态功能MRI数据。第二次访问于2022年完成。除上述MRI数据外，参与者在第二次访问时完成了认知功能评估。
混合效应回归模型分析发现，飞行训练提高了左额中回和左舌回的度中心性（DC）值。随后的相关性计算分析表明，这些改变与认知功能之间可能存在关联。
这些结果表明，飞行训练可能会促进前额叶和枕叶皮质的DC值，进而增强其执行功能。
