Muscle activities related to catching a ball were studied based on EMG signals of physiological characteristics and the elbow joint angle. When dropping a ball with different mass and visual information to the palm we are able to clarify how a human reacts based on their visual information prior to contact. An experiment was carried out using an EMG sensor and a motion capture system simultaneously. The EMG of palmaris longus, extensor carpi radialis longus, biceps brachii and triceps brachii were recorded. The reflection markers of the motion capture system were mounted at the joint positions of the wrist, elbow and shoulder. The integrated EMG of each muscle and the difference of the elbow joint angle were calculated from the balls release to contact. As a result, it was found that a bodies movement in relation to catching a ball from a fixed height is simplified via the influence of visual information from the balls release to contact.
