Split leap

Abstract: In rhythmic gymnastics execution quality depends directly on the level of technical expertise, as well as physical performance of the gymnast. the objective was to study the variation of execution factors, particularly the strength, speed and flexibility when performing gymnastics’ jumps split leap with and without throw-catch the ball. Five female gymnasts aged 12 to 15 years members of Tunisian national team of rhythmic gymnastics participated in this study. Every gymnast realized the split leap four times without apparatus and with apparatus. 2D motion analysis has been established to study the split leap with and without throw-catch the ball. The results show a significant variation of execution factors when introducing the apparatus such as the initial velocity, vertical displacement, the fly time, the component of vertical and horizontal force and the angular velocity of the split. When performing the split leap with apparatus, execution parameters show a significant decrease with the exception of the vertical velocity, acceleration and angular velocity of the split, which increase to compensate for the fall signs of strength and vertical displacement. Finally, the results showed also that probably gymnasts did not perform a jump with apparatus the best way that could. gymnastics.

Abstract: This study was conducted to examine and compare the parameters of leaps executed with two different take offs in rhythmic gymnastics. 15 rhythmic gymnasts competing in novice category (age: 7.6±0.7 years old; training age: 2.3±1.2 years; height: 120.4±2.4 cm; weight: 20.45±0.9 kg) participated in the study. The selection of the elements of split leap and stag leap with ring was based on ‘Rules of Procedure on Rhythmic Gymnastics’. The leaps were first executed with take off from one foot and then with take off from two feet. Gyko Inertial System (Microgate, Bolzano, Italy) and Optojump (Microgate, Bolzano, Italy) measurement tool were used to assess t flight, height, mean distance, velocity and total power of the leaps. SPSS 23 package program was used for the statistical analysis of data. Shapiro-Wilk test was performed to find out whether the data showed normal distribution while Mann-Whitney U test was performed to compare the groups. Statistical level of significance was accepted as p<0.05. The analysis indicated that t flight, height, velocity and total power results for the split leap performed with take off from 1 foot were significantly higher than the split leap performed with take off from 2 feet (p<0.05). As for stag leap with ring, a significant difference was observed in time of flight (t-flight) and velocity values of the leap executed with the two different take offs (p<0.05). At the end of the study, it was found that while performing split leap and stag leap with ring elements, gymnasts displayed a better performance with take off from single foot compared to take off from both feet. In light of these results, it is suggested to encourage rhythmic gymnasts in novice category perform technical training with take off from 1 foot during groundwork training.

Abstract: The perfection of the Split Leap movement in a series of rhythmic gymnastics contributes an assessment of the optimal performance of a rhythmic gymnastics athlete. The purpose of this study was to examine the Split Leap movement in rhythmic gymnastics in physiological, biomechanical and athlete rhythmic gym-nastics performance studies. This study using the Systematic mapping study methods. Writing about this split jump is analyzed using articles and books that are relevant to the topic of study that have been mapped before. Five databases were sought for empirical research published between 2003 and 2020. The study map was drawn from various reviews on the part of the connection with a review of research results and articles on topics around the SL movement as many as 41 articles. The relationship between strength, leg flexibility, range of motion , un-derstanding of motion techniques and Physiological support are key to split leap motion.
