XII biológica. O GC não recebeu qualquer tratamento especial, a fim de servir como referência padrão às variáveis a que se submeteram os grupos experimentais. Na análise de dados, além da estatística descritiva foram utilizados os testes de Shapiro Wilk (normalidade), Levene (homogeneidade) e ANOVA seguido do Post Hoc de Tukey (comparações intra e inter-grupos). O nível de significância foi de p<0,05. Os resultados revelaram melhora significativa a favor dos grupos experimentais, em ambas faixas etárias, tendo o GM alcançado resultados mais satisfatórios. Além disso, observou-se, também, em relação à divisão pela maturação biológica, a superioridade dos resultados nos subgrupos precoce. O poder do experimento foi de 99% em todas as variáveis.Desta forma, infere-se que, por causa das mudanças em importantes parâmetros físicos, pela maturação, a seleção de crianças para a prática da Ginástica Rítmica não deve se fundamentar apenas na idade cronológica, mas, sobretudo, na maturação biológica.Esses dados são fundamentados na melhora significativa no GM, quando comparado seus valores no pós-teste e com os demais grupos, levando a recusar a hipótese nula (H 0 ) levantada no vigente estudo.

XIII ABSTRACT Effects of two methods of sports training at different levels of biological maturation on the physical qualities of practicing rhythmic gymnastics of 08 and 09 years This study aimed to evaluate the effects of two different sports training methodologies, the traditional and maturity on the physical qualities of practicing rhythmic gymnastics girls aged 8-9 years in different levels of biological maturity. To this end, had their sample of 120 children divided randomly (by lottery), in six groups of 20 children, three at the age of eight years and three groups at the age of nine years: traditional training group (TG); Group training maturity (GM) and control group (CG). These groups were subdivided into early and late normal for the assessment of biological maturation by X-ray of hand and wrist, with the device model Sistem Medical Villa (Italian) 630 m, using the Greulich-Pyle Protocol. For the assessment of flexibility, explosive strength and coordination protocols were used LABIFIE (abduction of the shoulder joint and flexion of the lumbar spine), the test and the test Burpee Impulse Sargent Vertical Jump Test, respectively. The groups GT and GM performed rhythmic gymnastics education classes during the period of 16 (sixteen) weeks, with a frequency of 02 (two) times a week and with a duration of 45 (forty five) minutes each lesson, 10 minutes heating, the main part of 30 minutes and 5 minutes cool-down. The TG performed the traditional sports training methodology, which recommends the implementation of exercises according to the National Curriculum, which address sports, games, fights, gymnastics and rhythmic and expressive activities, taking into account chronological age. The GM group, conducted sports activities with emphasis ...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
