Pilots are usually under various different mechanical loads during flights, which can affect their musculoskeletal and cardiovascular system and even bring them injuries. Biomechanics mainly studies the mechanics and mechanobiology in medicine and biology. Aviation biomechanics studies the physiological response to different complicated mechanical loads during flights and the countermeasures. The research fields of aviation biomechanics include: mechanical loads on human body injury and related countermeasures, durative loads, vibration and noise on the physiological effects of human body and related comtermeasures, etc.
