abstract="In order to discuss the function of contraction force of pilot's neck region. Contraction force of pilot's neck region was measured in 22 volunteers aged 18-35 years. The mean contraction force is 102-396 N, the mean contraction time is 28 s. Authors think that training for pilot's neck muscular power is essential.<p /><p>Language: zh</p>",
