| Description | Tennis is a sport which can be played on different quality levels. They are based on basic tennis strokes which are influenced by many factors (duration and quality of tennis preparation, age, sex, level of condition abilities and coordination,…). Using optimal tennis technique requires to activate the whole body. Of course, the playing upper extremity and head of racket are dominant in the moment of contact tennis racket and the ball. Preparing good position for the correct tennis shot is also based on adequate activity of the other body parts, like undominant upper extremity, legs, core, etc. The big importance in this study had trajectories, velocities and accelerations of center of gravity and even much more important were kinematic parameters of the head of tennis racket during the tennis shots. We took into the consideration forward-backward, side (lateral) and vertical motion of center of gravity (x, y and z axis) and absolute velocities and accelerations of playing upper extremity with tennis racket and center of gravity as well. Three dimensional kinematic analysis with the help of Simi Motion software was used and we achieved precise kinematic indicators of 13 body segments and tennis racket. |
