简要总结
This pilot randomized controlled trial will investigate the effects of a 7-week core stabilization program performed on stable versus unstable surfaces in young competitive rhythmic gymnasts. Sixteen athletes will be randomized into two groups and will be assessed for changes in static balance and pivot performance.
详细描述
Rhythmic gymnastics requires high-level neuromuscular control, especially for skills involving balance and rotation. Core stabilization exercises are commonly included in training, but limited evidence exists regarding the impact of surface type on training effectiveness. This pilot study will compare the effects of a 7-week core stabilization program conducted on stable versus unstable surfaces on balance and pivot execution in rhythmic gymnasts aged 7-12. Participants will be randomly allocated into two equal groups and will be assessed pre- and post-intervention on selected balance and pivot tasks in accordance with Fédération Internationale de Gymnastique (FIG) standards. The study aims to inform future trials by estimating effect sizes and assessing the feasibility of the protocol.

结局指标
主要结局
Balance Duration
时间窗: Baseline and Week 7 (post-intervention)
Balance performance will be measured in seconds using a handheld stopwatch (Ultrak 250 Stopwatch Chronometer). Each gymnast will perform three static balance elements (passé, attitude, and side split with help) in relevé position while wearing half shoes. The timer will start once the gymnast achieves final posture and stop when balance is lost, form deteriorates, or the center of gravity shifts. Five trials will be performed for each element, and the longest successful attempt will be recorded. All tests will be performed with eyes open.
Pivot Performance (Number of Clean Rotations)
时间窗: Baseline and Week 7 (post-intervention)
Pivot performance will be assessed as the number of clean, full rotations executed without technical faults, based on Fédération Internationale de Gymnastique (FIG) regulations. Each gymnast will perform two pivot elements (passé forward and attitude) in relevé position while wearing half shoes, maintaining proper form and control. Five attempts will be performed for each pivot type, and the highest number of clean rotations will be recorded. All tests will be performed with eyes open.
