A KINEMATIC AND KINETIC ANALYSIS OF THE OVERGRIP GIANT SWING ON THE UNEVEN PARALLEL BARS

Abstract

Selected variables of the giant swing performed by fifteen gymnasts (10- 15 years old) on the uneven bars were investigated. Kinematic data, collected cinematagraphically, indicated significant differences m.10) between the skill level groups for: horizontal velocity of the Chi, peak velocity of the ankle and hip and for several segmental velocities and accelerations (foot, shank and arm). The uneven bar was instrumented with strain and torque gages to measure forces and torques directly on the bar. The mean maximum resultant force was 3.1 times body weight. The maximum mean torque was 4 1.3 Nm. Joint reaction forces and muscle moments were calculated. Mean vertical reaction force forces elbow and shoulder were 1.6 times body weight and the horizontal forces were 0.7 and 1.3 times body weight, respectively. Critical elements of the giant swing were identified to help teacher/coaches analyze and teach the giant swing.
