Abstract

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 (p < 0.05) in the cervical extension (p = 0.010) and left lateral flexion (p = 0.009) directions. The results can be used in strength training and clinical settings to potentially reduce the incidence of TBI.

评估针对头颈部创伤相关神经肌肉指标的 14 周颈部强化方案

颈部力量的增强可能会减少创伤性脑损伤（TBI）。这项研究的目的是确定使用新型颈部拉力装置进行颈部拉力训练的效果，以提高颈部等长拉力和力量发展速度（RFD）。参与者利用自我产生的向心力进行为期 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。与评估前后的测量结果相比，顺时针方向的 RFD 值增加了 4.344 倍，逆时针方向的 RFD 值增加了 5.978 倍。颈部伸展（p = 0.010）和左侧屈（p = 0.009）方向的等长颈部力量明显增加（p < 0.05）。这些结果可用于力量训练和临床治疗，从而降低创伤性脑损伤的发病率。
