Abstract
To compare the effects of different neck eccentric training devices on the neck strength and endurance of aviation cadets, and to explore their roles in the prevention of neck injuries, providing a basis for introducing specialized neck training in adolescent aviation schools. Two intervention groups used a helmet-style neck training device and elastic bands for neck training, respectively, while the control group underwent regular resistance physical training without additional neck intervention. Tests were conducted on neck flexion, extension, lateral flexion, and rotation in six directions before the intervention, and after 6 and 12 weeks. Significant time and group interaction effects were found in all six directions of neck strength indicators (F-values were 4.834, 8.496, 10.359, 6.849, 3.324, 2.405, p<0.05). The neck strength in all six directions significantly increased for both intervention groups at 6 and 12 weeks (P<0.05). In the control group, a significant increase in strength was observed in all directions except for extension at 6 weeks (P<0.05), but no significant changes were observed after 6 weeks (P>0.05). A significant time and group interaction effect was also found for endurance indicators (F=6.204, P<0.01). All three groups showed a significant increase in neck endurance at 6 weeks, but no significant changes were observed in the elastic band group and the control group after 6 weeks (P>0.05); the helmet group showed significantly higher neck endurance at 12 weeks (103.55 ±47.68) seconds, (P<0.01). Both 12-week helmet-style neck training and elastic band neck training can enhance trainee neck strength and flexural endurance, with the helmet-style training showing a more significant improvement in neck endurance.
