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 crossover 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, intramuscular coordination across the upper limbs. Care has to be taken when performing cable crossover exercises to ensure proper stabilisation of the joints during exercise execution and avoid joint overloading.

Introduction Strength training plays an integral part in the prevention of and rehabilitation from injury, as well as improvement of sports performance [1]. Thereby, the primary goal of strength training is to increase muscular strength for stabilising the joints while simultaneously improving interand intramuscular coordination [2]. Focusing on the shoulder joint and upper limb, injuries are very common in sport disciplines that involve overhead arm or throwing movements, such as tennis, baseball or basketball [3]. Here, welltrained chest muscles may help to reduce injury risks by better stabilising the shoulder joint and the interconnected upper limbs [4]. Bench press exercises are the most popular strength exercises for developing upper body strength, especially of chest muscles [5]. The core muscle groups which are trained during bench press exercises are the pectoralis major, the triceps brachii, the anterior deltoid and the medial deltoid, serving as key stabilisers of the shoulder joint [1]. Another common method to improve chest muscle strength is to perform strength exercises on a cable pulley system [6]. The cable pulley system offers a wide range of exercise execution types that can be adapted to individual preferences and requirements.
