Abstract:
Gymnastics, like all sports, witnessed a great development in all its fields of study especially biomechanics. Gymnastics’ motor skills have high score of difficulty in general and in vaulting able in particular. Thus, the researcher analyzed biomechanically all stages of table vaulting due to the great effect of these stages on the level of difficulty. In addition to that, knowing the biomechanical variables will help in organizing the training program for this skill as well as identifying its weaknesses and strengths. The Problem of the study lies in our low level of performance compared to Arabic and foreign countries as proven in the Arabic Tournament held in Qatar 2011. The aims of the study : 1. Identifying the most important biomechanical variables of every stage of performing on vaulting table. 2. Identifying the relationship between the most important variables of every stage of performing on vaulting table.The hypotheses of the study : There is significant correlation between the biomechnical variables for each phase at the HSPR salto tucked & the difficulty values. Field of the study : 1. Subject : young gymnast of Iraqi national team(13 - 14 years), season(2011 - 2012)2. Place : Iraq - Baghdad - gymnastic training centre - hall of (sameer khammas)3. Duration : intervene between(5/1/2012 & 4/6/2012).Review of literature : This field includes the theoretical studies that related in the study, Such us movement groups of the vault, the technical & mechanical face for the handspring salto tacked on vault, and the biomechanics concept, and the types of motor analyzing. Procedures of the Study : The researcher used the analytical descriptive method. The subjects of the study were (11) young gymnasts from the Iraqi National Gymnastic league then the researcher took only (6) gymnasts for this study who can perform this skill very well. Each gymnast was given three attempts and after taking his name, age, number and score of each attempt, the best attempt was counted.The researcher conducted a pilot study to identify the speed and place of the camera as well as the lighting and the aiding team’s positions. After that, he conducted the field experiment that included shooting front handspring salto tucked on vaulting table. The performances were presented to international referees to evaluate the level of their difficulty. The biomechanical variables were identified and analyzed using (KINOVEA) software. Finally the researcher used proper statistical operations after analyses including standard deviation, mean etc. Display of results : This field includes the results of the study with their discussions. Conclusions : The researcher came up with the following conclusions : 1. There is no significant correlation relationship between the variables of hitting the vaulting table and difficulty of performance except the angle of hip during the instant of landing on the table for it showed a significant relationship with the level of difficulty. 2. The timing of hitting the table compared to the subjects of the study was good and it was fit with the timing requirements of this movement.3. Most gymnasts didn’t reach fill extension during pivoting on the table thus there were some bending at knee joint.4. There is no significant correlation relationship between the variables of second flight stage and level of difficulty. Recommendations : Finally the researcher recommended the following : 1. Concentrating on the starting points of every stage and its end to ensure correct performance and not to affect the performance of next stage.2. Making similar studies on vaulting movements with higher difficulty.3. Using biomechanical analysis as a means for diagnosing errors in performance especially in high difficulty movements that cannot be controlled through observation.
