This study aimed to design a functional strength training program and evaluate its impact on the skill performance level of junior gymnasts on the vaulting table. Six gymnasts were 11–12 years old, participated as an experimental group. The findings revealed that implementing functional strength training positively influenced the skill performance level on the vaulting table, enhancing the gymnasts' execution and overall performance. Additionally, the program contributed to significant improvements in muscle strength, which is essential for gymnastics skills. The study highlights the importance of incorporating functional strength training as a core component in gymnastics training programs for juniors. Based on the results, the author recommends adopting the proposed program and its detailed implementation steps in training to enhance junior gymnasts' performance and physical abilities. This study provides a foundation for future research and practical application in gymnastics coaching and training.
