SEMG-based fighter pilot muscle fatigue analysis and operation performance research

Fatigue has a tremendously adverse impact on pilot performance. This study aims to explore the Biceps Brachii (BB), Rectus Femoris (RF), Flexor Carpi Radialis (FCR), and Tibialis Anterior (TA) activities of fighter pilots in the early and late combat stages, and the target hitting time. A total of 13 volunteers were recruited to conduct simulated combats inside a real fighter cockpit. The surface Electromyography (sEMG) was collected from all volunteers in the initial and final 20s of flight, and the target hitting time during three simulated combats was recorded. The root mean square (RMS) values of right BB and TA were significantly higher than the left side values (p ​
