背部肌肉群属于躯干肌的一部分。人体的躯干肌在人体生物中线两侧成对排列,两侧肌肉收缩产生矢状面上的前屈和后伸运动,一侧肌肉收缩则在额状面或横断面产生侧屈或旋转运动。承受重力、附肢肌收缩以及地面的反作用力时,颈肌和躯干肌协同收缩稳定椎骨。下面介绍一些背部练习的方法。一、杠铃俯身划船如图1所示,宽距站姿,双手正握杠铃,握距比肩稍宽,双 The back muscles belong to the trunk muscle part. Torso muscles of the human body are arranged in pairs on both sides of the midline of the living body. Muscle contraction on both sides produces flexion and extension movements on the sagittal plane while lateral muscle contraction produces lateral flexion or rotation on the frontal or transverse planes. To withstand gravity, muscle contraction of the appendage and ground reaction force, neck and trunk muscles synergistically shrink and stabilize the vertebrae. Here are some ways to practice back. First, the barbell bent over boating as shown in Figure 1, wide standing position, his hands are holding barbell, holding a bit wider than shoulder width, double
