An analytical study of the inter-relationship of the kinematics of performing the skill of cat jumping with the ball in rhythmic gymnastics

Rhythmic gymnastics skills are aesthetic skills that both spectators and players enjoy. These skills require motor coordination، motor transfer، and harmony between them. There are many tools used in rhythmic gymnastics skills، such as the hoop، ropes، and the ball. The ball was chosen as one of the tools to which skills are given within the kinetic chains of the tools. Rhythmic gymnastics، as music accompanies these skills to increase the beauty and harmony of the performance.
For this reason، the researchers decided to investigate the kinematic variables that help in the process of controlling the performance of the cat jump with the ball، and by studying these performance variables and knowing the inter-relationship between them، we will reach a greater understanding of the performance because digital biomechanics helps the performer to adjust his performance according to the angles and heights required in performing the cat movement. While throwing the ball upward، the researchers concluded، through motor analysis and extracting the values of the variables، that the rhythmic gymnastics players in the research sample were not at the required level of performance، as the large number of skills that the players take while they are still young does not give enough time to master the performance، as the performance needs to be repeated for a period of time that is not short to increase. Mastery، as well as their age of training، is another reason why they lose the concentration required to complete the skill accurately، as this skill requires high coordination and precise timing between throwing، jumping، and standing.
