Resumo: | Levels of aerobic fitness of children and adolescents are declining worldwide, which results in increased health risks. In Brazil, approximately 60% of the students present levels of fitness lower than recommended for age and sex. Our objective was to determine the influence of sexual maturation and physical activity level on cardiorespiratory fitness of schoolchildren of both sexes aged 9-14 years. This was a cross-sectional including a sample of 747 individuals (47.12% female) aged 9 to 14 years enrolled in public schools. The participants completed the Physical Activity Questionnaire for Children (PAQ-C) and a questionnaire on sexual maturation, and performed the shuttle run test. In order to verify the influence of sexual maturation on VO2max, students were categorized according to maturation stage (prepubertal, pubertal and postpubertal), sex, and interaction between sex and maturation. ANOVA was used to compare mean maturation stages and to assess whether sex and maturation affect VO2max. There was influence of maturation (p <0.0001; Eta2= 0.069, power = 1) and sex (p <0.0001; Eta2= 0.059, power = 1) on aerobic fitness. VO2maxvalues were different between the maturation stages in both sexes, and between sexes at the same maturation stage. Maturation influenced VO2maxwith a decreasing linear trend (p <0.0001; Eta2= 0.221, power = 1) for females. An influence of maturation and physical activity level on cardiorespiratory fitness was observed in schoolchildren of Aracaju city. |

No Brasil, aproximadamente, 60% dos escolares apresentam níveis de aptidão cardiorrespiratória abaixo do recomendado para a idade e sexo. O objetivo foi verificar a influência da maturação sexual e do nível de atividade física na aptidão cardiorrespiratória em escolares de ambos os sexos com idade de 9 a 14 anos. O estudo foi transversal com amostra composta por 747 indivíduos (47,12% do sexo feminino) e idade de 9 a 14 anos, matriculados na rede pública de ensino. Os indivíduos responderam o PAQ-C e o questionário sobre maturação sexual, além de participarem do shuttle run test. Para verificar a influência no VO2máx,os participantes foram categorizados em pré-púberes, púberes e pós-púberes e de acordo com o sexo e a interação (sexo vsmaturação). Foi utilizada a ANOVA para comparar as médias dos estágios de maturação e para avaliar se o sexo e a maturação afetavam o VO2máx. Houve influência da maturação (p < 0,0001; Eta2= 0,069; power = 1) e do sexo (p < 0,0001; Eta2 = 0,059; power = 1) na aptidão aeróbica. O VO2máxentre os estágios de maturação foi diferente entre os sexos. A maturação influenciou o VO2máx com tendência decrescente e linear (p < 0,0001; Eta2= 0,221; power = 1) para o sexo feminino.
