Table 1. Characteristics of excluded studies, selected for qualitative analysis (n=9).

Rhythmic gymnastics has been an Olympic sport since 1984, however, there are relatively few studies about this sport. In order to understand whether genetic predisposition could play a role in defining the flexibility phenotype in rhythmic gymnastics, the purpose of this study was to review the current literature and systematically identify common polymorphisms linked to genes correlated with joint mobility in elite rhythmic gymnastics. Systematic computerized searches were performed from 1950 to 2017 in the following databases: Medline, Embase, Cinahl, Lilacs, SPORTDiscus, Web of Science, Scopus and the Cochrane Central. Although the search initially identified 9761 studies, after removing duplicates and excluding by title and abstract, only 10 studies demonstrated potential to be included. After reading of full-texts, 9 studies were entered in the qualitative synthesis, thus only 1 study was eligible for this systematic review. The results of Tringali's study demonstrated that the COL5A1 CT genotype was linked to high joint mobility and to the occurrence of genu recurvatum. From this systematic review, further investigations are suggested to confirm the results of involving genes related to physiological and anthropometric determinants of rhythmic gymnastics performance.


La gimnasia rítmica ha sido un deporte olímpico desde 1984, sin embargo, hay relativamente pocos estudios sobre este deporte. Para entender si la predisposición genética podría desempeñar un papel en la definición del fenotipo de la flexibilidad en gimnasia rítmica, el propósito de este estudio era revisar la literatura actual e identificar sistemáticamente los polimorfismos comunes ligados a genes correlacionados con la movilidad articular en la gimnasia rítmica de élite. Se realizaron búsquedas sistemáticas computarizadas desde 1950 a 2017 en las siguientes bases de datos: MEDLINE, EMBASE, CINAHL, LILACS, SPORTDiscus, Web of Science, Scopus y la Central Cochrane. Aunque la búsqueda de la base de datos identificó inicialmente 9.761 estudios, después de quitar duplicados y de excluir por título y resumen, solamente 10 estudios demostraron el potencial que se incluirá. Después de la lectura de textos completos, se introdujeron 9 estudios en la síntesis cualitativa, por lo que solo un estudio fue elegible para esta revisión sistemática. Los resultados del estudio de Tringali demostraron que el genotipo COL5A1 CT fue ligado a la alta movilidad común y a la ocurrencia del genu recurvatum. A partir de esta revisión sistemática, se sugieren investigaciones adicionales para confirmar los resultados de la participación de genes relacionados con los determinantes fisiológicos y antropométricos del rendimiento de la gimnasia rítmica.
