ELBOW JOINT VARIABILITY DURING THE ROUND OFF IN FEMALE GYMNASTICS
Keywords: biomechanics, gymnastics, round-off, upper extremities, injury prevention
AbstractBased on a within-gymnast analyses this study aimed to examine the variability in elbow joint kinematics and kinetics of expert gymnasts in the execution of the round-off with different hand position. Six international level female gymnasts performed 10 trials of the round-off from a hurdle step to back handspring with “parallel” and “T-shape” hand position. Two force plates were used to determine ground reaction forces. Eight infrared cameras were employed to collect the kinematic data. Gymnast-specific variability was calculated using coefficient of variation (CV%) in each discrete kinematic and kinetic measures. In conclusion higher variability in the elbow joint abduction angle and adduction moment of force in the T-shaped hand position may leads to reducing repetitive abduction stress and thus protect elbow joint from overload.
