Effect of 12 Weeks Core Training on Core Muscle Performance in Rhythmic Gymnastics

Background: Rhythmic gymnastics performance is characterized by technical elements involving flexibility, aerobic capacity and strength. Increased core strength in rhythmic gymnastics could lead to improved sporting performance. Objective: The aim of this study was to analyze the effect of 12 weeks...

Increased core strength in rhythmic gymnastics could lead to improved sporting performance. Objective: The aim of this study was to analyze the effect of 12 weeks of core muscle training on core muscle performance in rhythmic gymnasts. Methods: A randomized controlled study involving 24 rhythmic gymnastics was conducted. Participants were randomly assigned to a control group (CG; <i>n</i> = 12; age 13.50 ± 3.17 years) or a training group (TG; <i>n</i> = 12; age 14.41 ± 2.35 years). Body composition, isometric strength of trunk, core endurance and core muscle electromyographic activity were measured (EMG) after 12 weeks of core training. Independent sample t-tests were carried out to compare baseline values between groups. A two-way repeated-measures analysis of variance (ANOVA) (time × group) was applied. Results: The TG improved body composition, trunk lean mass (mean differences MD = −0.31; <i>p</i> = 0.040), lean mass (MD = 0.43; <i>p</i> = 0.037) and bone mass (MD = −0.06; <i>p</i> < 0.001) after training. Core training increased isometric strength of trunk, flexion test (MD = −21.53; <i>p</i> = 0.019) and extension test (MD = 22.7; <i>p</i> = 0.049), as well as the prone bridge core endurance test (MD = −11.27; <i>p</i> = 0.040). The EMG values also increased in the TG in prone bridge for front trunk (MD = −58.58; <i>p</i> = 0.026). Conclusions: Core strength training leads to improvements in body composition, as well as improvements in trunk strength and increases in muscle electromyographic activity. These improvements could therefore improve performance during competitive rhythmic gymnastics exercises.Paula Esteban-GarcíaJosé Fernando Jiménez-DíazJavier Abián-VicénAlfredo Bravo-SánchezJacobo Á.
