吉他演奏高效率肌肉运动的原则

      左右手运动原则

 

      肌肉的对正: 肌肉运动只有在肌肉自然的与其关节对正时(不扭曲), 效率最佳, 自然的对正(Natural alignment)使得控制背部,手睕,手的肌肉得到最直接的收缩.

 

      关节Midrange[2]伸展状态: 肌肉运动只有在其所控制的关节在Midrange之间操作时效率最佳, Midrange位置与运动可提供肌肉伸缩最好的槓桿效果.

 

      一致的关节运动方向: 肌肉运动只有在手指的三个关节有一致的伸张或收缩时效率最佳, 关节一致的伸张或收缩简化了肌肉运动协调的问题.

 

      惯性的后续动作: 肌肉运动只有在手指有足够的后续动作而避免累积反效果的肌肉紧张时效率最佳, 足够的后续动作意味当一运动开始后, 不克刻意制止此动作.[3]

      Four Principles of Muscle Function 高效率肌肉运动的四原则

      Muscular Alignment: Muscles function most efficiently only when naturally aligned with their base and joint attachments. Natural aligned provides the most direct pull of the muscles that control your back, wrist, and finger joints.

 

      Midrange function of Joints: Muscles function most efficiently only when the joints they control are operated within their midrange of movement. Midrange positioning and movement provides optimum leverage to the muscles involved.

 

      Uniform Direction of Joint Movement: Muscles function most efficiently only when three joints of a finger or the thumb are either flexed or extended together. In contrast to flexing one joint while extending another, simultaneous extension or flexion simplifies coordination of the muscles.

 

      Follow-through: Muscles function most efficiently only when there is sufficient follow-through to avoid a build-up counterproductive tension. Sufficient follow-through means that, once a movement has been initiated, no intentional restraint is applied to the movement.
