This study investigated selected kinematic and kinetic variables of the overgrip giant swing on the uneven parallel bars. The subjects were 15 club gymnasts, who ranged in age from 10 to 16 years. Four judges ranked the 15 overgrip giant swings. Based on the judges' rating, three groups were formed. Group 1, the highly skilled, and Group 3, the lower skilled, were compared on kinematic and kinetic variables.Subjects--Topical Terms:

520 $a This study investigated selected kinematic and kinetic variables of the overgrip giant swing on the uneven parallel bars. The subjects were 15 club gymnasts, who ranged in age from 10 to 16 years. Four judges ranked the 15 overgrip giant swings. Based on the judges' rating, three groups were formed. Group 1, the highly skilled, and Group 3, the lower skilled, were compared on kinematic and kinetic variables.
520 $a The top rail of the bars was instrumented with strain and torque gauges to measure forces and torques directly on the bar. Joint reaction forces and net muscle moments were calculated for the elbow and shoulder joints. Comparisons between the two groups were made on absolute and temporal occurrences of events within the skill, body segment orientations, joint angles, body segment velocities and acceleration patterns and the path of the total body center of gravity.
520 $a There were significant differences between highly skilled and less skilled gymnasts for the horizontal velocity of the total body center of mass (4.9 and 4.4 m/sec, respectively) and the relative time of occurrence of the maximum vertical velocity of the center of mass. Significant differences were shown between the groups for peak velocity of the ankle and hip. Group 1 had a velocity of 11.0 m/sec for the ankle and 6.2 m/sec for the hip. Group 3 showed velocities of 9.6 and 5.6 m/sec, respectively. There were also significant differences for several segmental velocities and accelerations (foot, shank and arm), which were due to body position changes as the gymnasts completed the descent phase of the skill.
520 $a There were no significant differences between the groups on the kinetic variables. The total group mean maximum resultant force on the bar was 3.1 times body weight, which occurred in the second quadrant of the skill. The maximum mean torque on the bar was 41.3 Nm. Mean elbow joint reaction forces were 1.6 times body weight for the vertical force and 0.7 times body weight for the horizontal force. The shoulder joint calculations were 1.6 and 1.3 times body weight for the vertical and horizontal forces respectively.
