| 中文摘要: |
| 目的 研究一种针对肩袖肌群抗阻力量训练的肩袖训练器。方法 通过研究肩袖肌群的生物力学特征，分析肩袖肌力锻炼的最佳方式，提出基于摆动液压阻尼的训练方式，创造性地设计了基于阻尼大小输出的控制方式，并结合人体尺寸设计了肩袖训练器。通过肩袖肌群的抗阻训练，利用表面肌电测试仪对肩袖训练器和拉力器进行肌电实验测试，对比验证设计的可行性。结果 使用肩袖训练器训练时，目标肌肉激活顺序为大圆肌—冈下肌—前三角肌—尺侧腕伸肌—肱三头肌，更符合专业的旋肩运动发力顺序。使用肩袖训练器训练时，矢状轴旋转姿势下，冈下肌的做功占比为36.2%±11.9%;冠状轴旋转姿势下，冈下肌做功占比为37.2%±13.6%。结论 使用肩袖训练器进行肩袖抗阻训练的动作模式更为科学，并且无效做功少，更能激活肩袖肌群，达到更好的训练效果，对预防肩袖损伤和损伤修复具有一定的现实意义。 |
| 英文摘要: |
| The work aims to study a rotator cuff trainer for resistance training of rotator cuff muscles. By researching the biomechanical characteristics of rotator cuff muscles, an analysis was made to find the best way to exercise the rotator cuff muscles. Then, a training method based on oscillating hydraulic damping was proposed. Then, a control method based on damping output was designed creatively and a rotator cuff trainer was also designed according to the human body size. Through the resistance training of rotator cuff muscles, myoelectric test was carried out to the rotator cuff trainer and chest expander with myoelectric tester to verify the feasibility of design. When rotator cuff trainer was used for exercise, the muscle mobilization sequence was teres major-infraspinatus-anterior deltoid-extensor carpi ulnaris-triceps brachii, which was more in line with the sequence of professional shoulder rotation. When the rotator cuff trainer was used to rotate on sagittal axis, the percentage of infraspinatus’s work was 36.2%±11.9%. For coronall axis, the percentage of infraspinatus’s work was 37.2%±13.6%. The exercise mode of using rotator cuff trainer for resistance training of rotator cuff muscles is more scientific with less invalid work, which can activate the rotator cuff muscles better and realize better training effects, thus having practical significance for preventing rotator cuff injury and repairing injury. |
