[Purpose] This study examined differences in neck muscle activity in two different head positions during tackles with the aim of contributing to the prevention of sports injuries. [Subjects] The subjects were 28 male high-school rugby players. [Methods] Two tackle positions were considered: a head-up position and a head-down position. Muscle activities of the sternocleidomastoid muscles and the upper, middle, and lower parts of the trapezius muscles were measured. [Results] Muscle activities of the sternocleidomastoid muscles and the right upper trapezius muscle were significantly increased in the head-up position, and the activity of the lower trapezius was significantly increased in the head-down position. [Conclusion] Tackling with the head-up position increases neck muscle activity and stability of the head and the neck.
[目的]本研究旨在通过检查两种不同头部姿势在擒抱动作中的颈部肌肉活动差异，为预防运动损伤提供帮助。[对象]研究对象为28名男性高中橄榄球运动员。[方法]考虑两种擒抱姿势：抬头姿势和低头姿势。测量胸锁乳突肌以及斜方肌上、中、下部分的肌肉活动。[结果]抬头姿势下胸锁乳突肌和右侧斜方肌上束的肌肉活动显著增加，低头姿势下斜方肌下束的活动显著增加。[结论]采用抬头姿势进行擒抱可增加颈部肌肉活动以及头部和颈部的稳定性。
