The research aims to identify the differences between the effect of each training on a modified balance model based on mathematical confidence (mathematical confidence as a condition- mathematical confidence as a feature) and the level of compulsory sentence performance on the balance beam (10) years were divided into two equal groups, one experimental and the other controlling,, each of which consisted of (8) junior gymnasts, and "from the research tools: Physical tests - Mathematical confidence scale - assessing the level of compulsory sentence performance on the balance beam - exercises on the adjusted and approved balance beam device, and the most important statistical methods: arithmetic mean- standard deviation- median- torsion coefficient - simple correlation coefficient - "T" test - rate of change. Among the most important results: Training on the modified balance beam has a statistically significant positive effect at the level of (0.05) on sports confidence and the level of compulsory sentence performance on the balance beam for junior gymnasts under (10) years. ' Training on the approved balance beam apparatus has a positive, non-statistically significant effect at the level of (0.05) on sports confidence and the level of compulsory sentence performance on the balance beam for female gymnasts under (10) years. There are statistically significant differences between the dimensional measurements of the experimental- and control groups in the mathematical confidence and the level of performance of the obligatory sentence on the balance beam of the female gymnasts in favor of the experimental group. Recommendations: The necessity of training on the modified balance beam apparatus because of its effective impact on developing sports confidence (sports confidence as a case - sports confidence as a feature) and the level of compulsory sentence performance on the balance beam for junior gymnasts under (10) years.
