| Abstract | ||
| Gymnastic is characterized by developing the technical performance through creation and brevity where competition in international championships has become a difficulty. The study problem lies in the difficulty faced by the coach while training the technical performance of sports movement, gymnastic in particular, because of movement speed and the intervening movements in case the movement is highly difficult. The study aims at identifying the values of some biomechanical variables of Shmisany movement and technical performance mistakes through biomechanical analysis. The study also aims at making correcting exercises in accordance with the mistakes and identifying changes in values of biomechanical variables of Shmisany movement. The descriptive approach is used in the study. The study sample was deliberately selected, consisting of one player in the Iraqi National Team for Gymnastic for (2010). Questionnaire, measurement and scientific observation were the means for collecting data. Some biomechanical variables were used in concluding the results (distance, time and speed of the preparatory, main and final stages, the equipment leaving and touching angle …) The study sample was video taped and then biomechanical analysis was done using I Film Edit 1.3, Adobe Premiere 6.5, ACDSee 10 Photo Manager, AutoCAD 2012, Microsoft Office Excel 2010 software. Change ratio law was used for the statistical analysis of the results. The study concluded that the correcting exercises increase the real distance of both the preparatory and the main stages that in turn decrease the real distance of the final stage. The correcting exercises also increased the time of performing the three stages, the preparatory, the main and the final. Body mass weight centre speed for both the preparatory and the final stages largely decreased but increased for the main stage because of the correcting exercises. The researcher recommended that the second flight height should be more in order to allow for the player to complete the jump and to collect all body parts while making the round circular turn in the second flying in order to decrease inertia and increase motor movement. This will complete the turn circularly and prepare the player to move for the final stage of landing. It is also confirmed that rolling should be completed while making the air turn in the second flying and not delaying body stretch at the end of rolling stage. Body positions and joints that have an efficient role in implementing the movement should be stressed. | ||
