Aim of the article is describe muscle activation of target kinetic chain in softball windmill throw, stand discuss throw and selected strengthening excercises (hang clean and hang snatch) by using the EMG and based on the EMG graph reveal differences or similarities of muscle activation in selected exercises. We used two methods for describe and analyze of selected exercises. For external describe of movement we used kinematic analysis (2D) and for muscle activation EMG. Monitoring was assured by 2 cameras located upright on performed movement. Dartfish was used to evaluate all kinematic values. There was found similar local muscle extremities and maximal muscle activities between stance discuss throw and softball windmill pitch. Muscle activity measured in the forearm area was found to be consistent in all measured exercises, and muscles of maximum free contractions (MVCs) reached their dynamic phases.

Keywords: softball; pitching; discuss throw; snatch; clean; EMG; kinematic analysis
