目的：评估瑞士球前后不同核心稳定性练习中腰盆肌的活动。设计：前瞻性比较研究。地点：研究实验室。参与者：8名来自大学人群的健康志愿者。干预：受试者在瑞士球上和下进行4种练习：斜压、上身前伸、单腿保持和四足训练。主要观察指标：选定的腰盆肌肉的表面肌电信号，归一化为最大自主等长收缩，肌电功率谱的中值频率分析。视觉模拟量表对任务难度的感知。结果：随着单腿持球和瑞士球上压的表现，腹直肌的激活显著增加。结论：虽然有证据表明瑞士球为腹直肌提供了训练刺激，但这种变化与核心稳定性训练的相关性有待进一步研究，因为稳定性训练的重点是尽量减少腹直肌的活动。还提供了关于核心稳定的四足动物练习质量的进一步支持。
Objectives: To assess lumbopelvic muscle activity during different core stability exercises on and off a Swiss ball.Design: Prospective comparison study.Setting: Research laboratory.Participants: Eight healthy volunteers from a university population.Intervention: Subjects performed 4 exercises on and off a Swiss ball: inclined press-up, upper body roll-out, single-leg hold, and quadruped exercise.Main Outcome Measures: Surface electromyography from selected lumbopelvic muscles, normalized to maximum voluntary isometric contraction, and median frequency analysis of electromyography power spectrum. Visual analog scale for perception of task difficulty.Results: There was a significant increase in the activation of the rectus abdominus with performance of the single-leg hold and at the top of the press-up on the Swiss ball. This led to changes in the relation between the activation levels of the lumbopelvic muscles measured.Conclusions: Although there was evidence to suggest that the Swiss ball provides a training stimulus for the rectus abdominus, the relevance of this change to core stability training requires further research because the focus of stabilization training is on minimizing rectus abdominus activity. Further support has also been provided about the quality of the quadruped exercise for core stability.
