Increased neck strength has been linked to a potential decrease in traumatic brain injuries (TBI). The purpose was to determine the efficacy of a neck-strengthening protocol using a novel neck-strengthening device to increase isometric neck strength and rate of force development (RFD). Utilizing self-generated centripetal force, participants trained for 14 weeks. A linear mixed model was used to analyze the relationship between post-assessment measurements and pre-assessments measurements, while accounting for repeated measure random effect at the individual level, and a regular random error term. RFD values were 4.344 times higher in the clockwise direction and 5.978 times higher in the counterclockwise direction when comparing pre and post assessment measurements. Isometric neck strength increased significantly ( < 0.05) in the cervical extension ( = 0.010) and left lateral flexion ( = 0.009) directions. The results can be used in strength training and clinical settings to potentially reduce the incidence of TBI.
颈部力量增强与创伤性脑损伤（TBI）潜在减少有关。目的是确定使用新型颈部强化装置的颈部强化方案在增加等长颈部力量和力量发展速率（RFD）方面的功效。参与者利用自身产生的向心力进行了14周的训练。采用线性混合模型分析评估后测量值与评估前测量值之间的关系，同时考虑个体水平的重复测量随机效应和常规随机误差项。比较评估前和评估后测量值时，顺时针方向的RFD值高4.344倍，逆时针方向高5.978倍。等长颈部力量在颈椎伸展方向（P = 0.010）和左侧弯曲方向（P = 0.009）显著增加（P < 0.05）。这些结果可用于力量训练和临床环境，以潜在降低TBI的发生率。
