Summary

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.

Detailed description

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.

Interventions

Type	Name	Description
OTHER	Core stabilization on stable surfaces	Participants will perform a structured core stabilization training program on stable surfaces, such as the floor and rigid foam blocks. The program includes functional exercises targeting trunk control, postural alignment, and balance, delivered three times per week over a 7-week period.
OTHER	Core stabilization on unstable surfaces	Participants will perform the same structured core stabilization training program as the stable surface group, but on unstable surfaces such as BOSU balls and wobble boards. The intervention is designed to challenge balance, proprioception, and core muscle activation. Sessions are conducted three times per week over a 7-week period.
