Knowledge of the current status of motor abilities allows valid evaluation of the objective situation and forecast further development of rhythmic gymnasts. The main objective of this research was to determine the difference and connection between the motor abilities of rhythmic gymnasts depending on the program level, biological age and achieved national ranking. Research results stemming from using multivariate analysis of variance showed a statistically significant difference in the estimated motor abilities between junior rhythmic gymnasts in A, B and C level programs. The univariate analysis of variance has shown that differences in motor skills between rhythmic gymnasts’ different programs were statistically significant. A-level rhythmic gymnasts have produced better results in all tests for the assessment of flexibility, coordination and strength. The research related to differences in motor abilities between junior rhythmic gymnasts with regard to the achieved ranking showed no statistically significant difference, whereas biological age made a statistically significant difference. Pearson's correlation coefficient revealed significant relations between some motor abilities among rhythmic gymnasts in A, B and C level programs. The correlatives were higher as the level of the program was higher and vice versa. Two tests had the largest contribution to the success achieved in the competition, the figure of eight with a bend test and bend on the bench test, which assesses overall flexibility. The scientific value of the proposed research is aimed at better planning, programming and control of the training process in rhythmic gymnastics. Keywords: rhythmic gymnastics, program level,motor abilities

克罗地亚共和国青少年艺术体操运动员的运动能力模型值

了解运动能力的当前状态可以有效评估客观情况并预测艺术体操运动员的进一步发展。这项研究的主要目的是确定艺术体操运动员的运动能力之间的差异和联系，具体取决于程序级别，生物学年龄和获得的国家排名。使用多元方差分析得出的研究结果显示，在A，B和C级别项目中，初级艺术体操运动员之间的运动能力估计值存在统计学差异。对方差的单变量分析表明，艺术体操运动员不同程序之间的运动技能差异具有统计学意义。在进行柔韧性评估的所有测试中，A级艺术体操运动员的成绩都更好，协调和力量。与初级艺术体操运动员之间的运动能力差异有关的研究表明，排名没有统计学上的显着差异，而生物学年龄则具有统计学上的显着差异。皮尔森的相关系数揭示了艺术体操运动员在A，B和C级程序中某些运动能力之间的显着关系。程序级别越高，相关性越高，反之亦然。两项测试对比赛的成功贡献最大，其中八项测试采用弯曲测试和卧推测试，以评估整体灵活性。拟议中的研究的科学价值旨在更好地计划，规划和控制艺术体操训练过程。关键字：
