Resumo: | Adolescence is a phase characterized by important physical and maturational alterations, with individuals of the same chronological age, but who are more mature, may present sportive advantages because of greater force gain and additional muscle mass. Thus, in studies evaluating motor skills of children and adolescents, maturational classification should be an efficient and easily applicable tool in order to facilitate the interpretation of the true relationship between maturation and motor performance. Therefore, the objective of this study was to compare the relationship between motor performance and different types of classification of biological maturation in 209 boys aged to 17 years (11.59 ± 2.57) practicing soccer. Anthropometric variables were obtained according to the ISAK criteria. Biological maturation was determined based on age at peak height velocity (PHV) and also by self-assessment of sexual maturation (genitalia and pubic hair). Motor performance was evaluated by sit-and-reach tests, horizontal jump, modified push-ups, 50-m run, and 9/12-min run/walk. The results showed progression in the variables analyzed as the subjects reached maturity. Correlation analysis and the egression values indicated higher consistency for the PHV classification, which better explained motor performance according to maturational status, exceeding the values obtained by comparison according to age or sexual maturation. Thus, the use of PHV as a classification instrument is preferably recommended for youngsters with haracteristics similar to those of the present sample. |

Assim, no contexto esportivo e nas pesquisas, envolvendo crianças e adolescentes, é necessária a classificação maturacional, de forma eficiente e de fácil aplicação, auxiliando na interpretação da verdadeira relação entre a maturação e desempenho motor. Sendo assim, o objetivo do estudo foi comparar a relação entre o desempenho motor e diferentes formas de classificação da maturação biológica, envolvendo 209 rapazes de seis a 17 anos (11,59±2,57), praticantes de futebol. As variáveis antropométricas foram obtidas seguindo-se os critérios estabelecidos pela ISAK. A maturação biológica foi determinada pela idade do Pico de Velocidade de Crescimento (PVC) e pela determinação da maturação sexual (genitálias e pêlos) através da auto-avaliação. O desempenho motor foi determinado por testes de sentar-e-alcançar, salto horizontal, abdominal modificado, corrida de 50 metros e corrida/caminhada de 9/12 minutos. Os resultados indicaram evolução das variáveis analisadas à medida que os indivíduos avançavam na maturação. A análise de correlação e os valores da regressão apontaram maior consistência na utilização da classificação pelo PVC como melhor explicação para o desempenho em testes motores, segundo o status maturacional, superando os valores encontrados nas comparações por idade ou maturação sexual. Desta forma, o uso do PVC como instrumento de classificação biológica passa a ser preferencialmente recomendado para jovens com características semelhantes à amostra utilizada neste estudo.Universidade Federal de Santa Catarina.
