Caracterização da cinemática de paratletas no voleibol sentado

Abstract

This study aimed to evaluate linear kinematic of sitting volleyball players during a game situation as well as angular kinematic of body posture while making base sitting displacement. For this, were used 11 sitting volleyball players. Physical discomfort situations were investigated before and after the game, anthropometric data, functional reach capacity, mobility degree to the body trunk and shoulder, distances involved and reached speeds. The discomfort degree was plotted in a diagram of painful areas. Physical mobility degree was diagnosed by Vicon® kinematics system. Linear kinematics was measured by videogrammetry tracking method, using the software DVideo®. Data analysis was carried out in various software as Nexus Vicon®, Polygon Vicon® and MatLab®. The results showed 72.7% of pain complaints after the game and in particular to the shoulders, an average functional trunk range of 0.41 ± 7,87m, a standard motion range of 35.45 ± 4.08 degrees for trunk, 63.30 ± 6.41 to 66.08 ± for right shoulder and 4.61 for left shoulder due to displacement, an total distance traveled in the game of 487.72m and with the highest average speed 7.10 ± 0,84m/s for a period of time. With this it was concluded that sitting volleyball required from the player high speed for short distances, in which the shoulders were required in more mobility degrees than the stem displacement in all directions and the game triggered practice many painful complaint.
