[Purpose] The aim of this study was to present an individualized resistance training method to enable exercise while maintaining an exercise load that is set according to an individual's joint angle-torque using a haptic-based resistance training machine. [Methods] Five participants (machine group) performed individualized shoulder internal and external rotation training with a haptic resistance training machine, while another five participants performed general dumbbell-based shoulder internal and external rotation training for eight weeks. Internal and external rotation powers of subjects were measured using an isokinetic machine before and after training. [Results] The average powers of both shoulder internal and external rotation has been improved after training (25.72%, 13.62%). The improvement in power of external rotation in the machine group was significantly higher than that in the control group. [Conclusion] This study proposes a haptic-based individualized rotator cuff muscle training method. The training protocol maintaining the joint angle-torque profile showed better improvement of shoulder internal/external rotation than dumbbell training.
[目的] 本研究旨在提出一种个性化抗阻训练方法，以便在使用基于触觉的抗阻训练机器时，能够在保持根据个体关节角度-扭矩设定的运动负荷的同时进行锻炼。[方法] 五名参与者（机器组）使用触觉抗阻训练机器进行个性化的肩部内旋和外旋训练，而另外五名参与者进行为期八周的常规哑铃肩部内旋和外旋训练。在训练前后使用等速运动机器测量受试者的内旋和外旋力量。[结果] 训练后肩部内旋和外旋的平均力量均有所提高（分别提高25.72%、13.62%）。机器组外旋力量的提高显著高于对照组。[结论] 本研究提出了一种基于触觉的个性化肩袖肌训练方法。保持关节角度-扭矩曲线的训练方案在改善肩部内/外旋方面比哑铃训练效果更好。
