Brain function factors after high acceleration exposure in Korea Air Force cadets

Fighter pilots perform a variety of physical activities to improve and maintain their fitness, but there is a lack of research on brain function factors for high acceleration exposure. Therefore, the aim of this study was to investigate the differences of physical fitness between success and failure group, and to examine the changes in blood brain function factors after exposure to high acceleration condition. Air force cadets were participated and divided into the success (n=38), failure within 10 s (failure group A, n=19), failure within 20 s (failure group B, n=10) and failure within 30 s (failure group C, n=12) groups after conducting G-tolerance test. In terms of muscle mass, the failure group C showed significantly higher values than the failure group A (p<0.05). In the sit-up test, the success group showed significantly higher values than the failure group D (p<0.05). BDNF and CTSB levels were significantly increased in the success group and the failure group D after acceleration exposure (p<0.05). As can be seen from the results of this study, high acceleration exposure caused a significant increase in the CTSB level in the success group that is considered to be the result of high strength isometric movement of the human body to withstand high pressure. Therefore, the results of this study suggested that to improve muscle strength is essential to withstand high acceleration conditions.
