Study on Influencing Factors of Neck Movement during Pilot Flight and Neck Specific Training
To explore the influencing factors of neck movement during pilot flight and to evaluate the effect of the neck muscle special training,104 pilots and 8 male volunteers were selected and MCU neck function testing system was used to measure the neck strength of the pilots and volunteers in 6 directions.The neck training and injury status of the pilots were obtained through a survey question-naire.In addition,specialized neck muscle training was conducted on volunteers.The strength differences between pilots and volunteers of the same age before and after neck muscle training were also compared.The neck strength of pilots aged≥40 decreased compared to other age groups,and there was a significant change(P<0.05).The strength of pilots who master correct neck muscle training methods was stronger(flexion)significantly(P<0.05).Meanwhile,pilots who experienced neck pain during flight had relatively weaker neck strength,while pilots who could move their neck freely during flight had stronger neck strength.The neck strength of volunteers untrained was signifi-cantly lower than that of pilots.However,after training,the neck strength of volunteers significantly increased(P<0.05)and exceeded that of pilots of the same age(P<0.01).In this study,there was no significant correlation between neck pain or turning difficulty during flight and participation in specialized neck training,while mastery of correct training methods was significantly correlated with neck turning under load(r=-0.225,P=0.033).
