Construction and Validation of a Specific Balance Test for Rhythmic Gymnasts: A Pilot Study

Area of Science:

• Sports Science
• Biomechanics
• Motor Control

Background:

• Balance is crucial in rhythmic gymnastics, impacting technical execution and routine aesthetics.
• Existing balance tests do not fully capture the sport's complex demands, requiring simultaneous stability, apparatus manipulation, and rhythmic synchronization.
• A need exists for a specialized test combining motor and cognitive challenges for accurate athlete assessment.

Purpose of the Study:

• To develop and validate a specific balance test for rhythmic gymnasts (BTRG).
• To assess the reliability and construct validity of the BTRG.
• To provide a precise tool for evaluating rhythmic gymnasts' functional abilities.

Main Methods:

• The study included 12 young female gymnasts (average age 9 years).
• Participants completed anthropometric measurements, standard motor tests, and the novel BTRG.
• Test-retest procedures assessed reliability, while factor analysis evaluated construct validity against existing tests.

Main Results:

• The BTRG demonstrated excellent reliability (ICC = 0.96) and discriminant ability between gymnasts of different programs.
• Factor analysis confirmed the BTRG measures specific balance constructs as hypothesized.
• The test showed high reliability (CV = 6.4%; SEM = 0.18).

Conclusions:

• The BTRG is a potentially valid and reliable tool for assessing specific balance in rhythmic gymnastics.
• This test may enhance training, athlete evaluation, and talent identification in the sport.
• Findings are preliminary from a pilot study and should be interpreted cautiously.
