Injuries to the shoulder are very common in sports that involve overhead arm or throwing movements. Strength training of the chest muscles has the potential to protect the shoulder from injury. Kinematic and kinetic data were acquired in 20 healthy subjects (age: 24.9 ± 2.7 years) using motion capture, force plates for the bench press exercises and load cells in the cable for the cable pulley exercises with 15% and 30% of body weight (BW). Joint ranges of motion (RoM) and joint moments at the shoulder, elbow and wrist were derived using an inverse dynamics approach. The maximum absolute moments at the shoulder joint were significantly larger for the cable pulley exercises than for the bench press exercises. The cable cross-over exercise resulted in substantially different joint angles and loading patterns compared to most other exercises, with higher fluctuations during the exercise cycle. The present results indicate that a combination of bench press and cable pulley exercises are best to train the full RoM and, thus, intra-muscular coordination across the upper limbs. Care has to be taken when performing cable cross-over exercises to ensure proper stabilisation of the joints during exercise execution and avoid joint overloading.
在涉及过顶手臂或投掷动作的运动中，肩部受伤非常常见。胸部肌肉的力量训练有可能保护肩部免受损伤。使用动作捕捉技术，在20名健康受试者（年龄：24.9±2.7岁）中获取了运动学和动力学数据，使用测力板测量卧推练习中的力，使用拉力传感器测量体重15%和30%的滑轮拉力练习中的力。采用逆动力学方法得出肩部、肘部和腕部的关节活动范围（RoM）和关节力矩。滑轮拉力练习中肩关节的最大绝对力矩明显大于卧推练习。与大多数其他练习相比，滑轮交叉练习导致关节角度和负荷模式有很大不同，练习周期内波动更大。目前的结果表明，卧推和滑轮拉力练习相结合最适合训练整个RoM，从而训练上肢的肌肉内协调性。进行滑轮交叉练习时必须小心，以确保练习过程中关节的正确稳定，并避免关节过载。
