SPECIFICITY OF INTERMUSCULAR COORDINATION IN THE BASEBALL HIT IN RELATION TO THE ANGULAR VELOCITY OF THE BAT SEGMENT

The aim of this study was to estimates the relation between the kinematic structure of the baseball strike movement in adolescent baseball players and the applied muscles electromyographic activity.The research was carried out during the movement of the bat in thirteen-year-old baseball players (n = 5).The used video recording with two cameras from different points of view was synchronized with conducted surface electromyography.The obtained results are of essential importance for the coaches in a developing and using correct methods in the training process to improve the technical skills of the athletes.Our results relate the muscle activity with the trajectory and speed of the bat during the stroke, which benefits in improving the efficiency in hitting.
