Effects of proprioceptive training using BOSU® balance trainer on core strength and static balance in young competitive rhythmic gymnasts

Purpose: The study aimed to examine the effects of eight weeks of proprioceptive training using a BOSU® balance trainer on core strength and static balance in young rhythmic gymnasts. Methods: Twenty-three young competitive female rhythmic gymnasts, (age: 9.7 ± 1.9 yrs; weight; 26.1 ± 6.5 kg; height: 131.2 ± 10.9 cm; years of experience in RG: 3.5 ± 1.7) were assigned into an experimental group (EG, n = 12) and a control group (CG, n = 11). Both groups underwent a series of tests included the side bridge test, the stork stand balance test, and the rhythmic gymnastics balance test before and after the experimental intervention. All participants engaged in regular rhythmic gymnastics training throughout the intervention period with EG supplemented with BOSU® balance trainer proprioceptive training. The intervention programme consisted of six sets of exercises that focused on improving core strength and static balance. Training volume was kept consistent throughout the experiment, with each exercise performed for 30 s followed by a 45-s rest in 2 sets, 3 times a week. Results: Results showed that EG improved core strength significantly for right (P < 0.001) and left (P = 0.038) sides. However, there was no significant difference found in static balance (Stork Stand Balance Test and Rhythmic Gymnastics Balance Test) between EG and CG. Conclusion: The study concluded that proprioceptive training using BOSU® balance trainer implemented for 8 weeks on young competitive rhythmic gymnasts improved core strength but not in static balance
