Olimpik havalı tabanca atış pozisyonunun biyomekanik analizi

Abstract

In this study, a 60-shot competition flow test was applied for the biomechanical analysis of the olympic air pistol shooting position. One elite, three advanced and four beginner level shooters participated in the study. First of all, MoCap based aiming point trajectory assessment method developed to detect the displacement of the aiming point. Then, the exhaustion test was applied to determine how the muscles determined by the pre-tests behaved in the limits. Finally, the displacement of aiming point and COP, muscle activation and joint angles of the shooters in shooting position were determined. The relations of these components with each other were examined for the last second before the shot. In research, no relationship was found between the firing time and other components (p<0.05). It was observed that the movement of the aiming point in the vertical axis and the movement of the COP in the ML direction were less. It was determined that the shoulder and back muscles of the athletes were more active than the arm muscles and the activity of the brachioradialis muscle increased as the level decreased. It was observed that the upper extremities of the shooters differed in joint angles and they had an acceptable level of flexibility. For the displacement of the aiming point, the extension-flexion angle of the deltoid, trapezius, infraspinatus, birachioradialis and biceps muscles other than the triceps and hip, the extension-flexion angle of the head relative to the spinal cord and the extension-flexion angle of the right hand relative to the right forearm are related (p<0.05) was determined. It was seen that there was no relationship between COP displacement (p>0.05). As a result, success can be achieved by consistently repeating high-scoring shoots. It has been observed that the elite level uses the shoulder and back muscles more actively, provides similarity in joint angles with each shot, and reduces the movement of the aiming point. Shooters must reduce the movement of the aiming point and repeat it consistently for a high score.
