Purpose This study aimed to analyze the G-test results based on body composition and heart rate of fourth grade Air Force cadets, identify the relationships among body composition, heart rate, and G-resistance, and provide basic data for pilots and Air Force cadets to strengthen the G-tolerance. Methods This study used wearable devices to measure the heart rate and fatigue of 27 fourth-grade cadets of the Air Force Academy. Physical composition and physical fitness were assessed. Based on the measurement results, G-test result analysis and correlation analysis were performed. Results G-test results showed a steady heart rate (p=.015), deep sleep time (p<.001), and fatigue (p=.008) which have significant differences. Further, a 10-second heart rate at G-test (p<.001) and maximum heart rate (p<.001). There was also a statistically significant difference. Conclusions Effective G-test success for Air Force cadets would require improving aerobic performance, continuous fatigue, and physical fitness management. If various variables that affect G-test are analyzed and applied to physical education and physical training through continuous research over the next 2–3 years, it is expected to have a better outcome on the G-test success for every cadet.
