This study aimed to investigate the effect of different support surfaces on trunk muscle activity during slap shots and wrist shots in ice hockey players by analyzing muscle activation patterns across varying conditions. A total of 22 healthy male collegiate ice hockey players participated in this study. Ice hockey players were assessed for muscle activity in their trunk muscles (rectus abdominis, external oblique, internal oblique, and erector spinae). Each player performed a slap shot and wrist shot on solid ground, a slap shot and wrist shot on ice, and a skating slap shot and wrist shot on ice. Data from a 3 s interval, excluding the first and last second of the 5 s measurement period, were used for analysis. All electromyography signals were normalized using maximal voluntary isometric contraction. Significant differences were found in all muscles except for the external oblique, depending on the support surface and shooting method. ( < 0.05). The muscle activity of the rectus abdominis was significantly greater for the slap shot and wrist shot on ice than for the slap shot and wrist shot on the ground, and the slap shot and skating slap shot on ice than for the wrist shot on the ground ( < 0.05). The internal oblique was significantly higher for slap shots and wrist shots on ice than for slap shots and wrist shots on the ground ( < 0.05). The erector spinae was significantly greater for the skating slap shot and wrist shot on ice than for the wrist shot on the ground, and the skating slap shot on ice was significantly greater than the skating wrist shot on ice ( < 0.05). To enhance the shooting efficiency of ice hockey players competing on ice, exercises on unstable surfaces and targeted trunk muscle training are considered to be effective.
本研究旨在通过分析不同条件下的肌肉激活模式，调查不同支撑表面对冰球运动员在抽射和腕射过程中躯干肌肉活动的影响。共有22名健康的男性大学冰球运动员参与了本研究。对冰球运动员的躯干肌肉（腹直肌、腹外斜肌、腹内斜肌和竖脊肌）的肌肉活动进行评估。每位运动员在坚实地面上进行一次抽射和腕射，在冰面上进行一次抽射和腕射，以及在冰面上进行一次滑行抽射和腕射。使用5秒测量期内除第一秒和最后一秒外的3秒间隔的数据进行分析。所有肌电图信号均使用最大自主等长收缩进行标准化。除腹外斜肌外，所有肌肉均根据支撑表面和射门方法存在显著差异（<0.05）。腹直肌在冰面上的抽射和腕射时的肌肉活动明显大于在地面上的抽射和腕射，以及在冰面上的抽射和滑行抽射时的肌肉活动明显大于在地面上的腕射（<0.05）。腹内斜肌在冰面上的抽射和腕射时明显高于在地面上的抽射和腕射（<0.05）。竖脊肌在冰面上的滑行抽射和腕射时明显大于在地面上的腕射，且冰面上的滑行抽射明显大于冰面上的滑行腕射（<0.05）。为提高在冰面上比赛的冰球运动员的射门效率，在不稳定表面上进行练习和有针对性的躯干肌肉训练被认为是有效的。
