Abstract

ResumoIntrodução: A recomendação atual para prática de atividades físicas na infância e adolescência é de que todo jovem deveria envolver-se diariamente por 60 minutos ou mais em atividades físicas moderadas em cinco ou mais dias da semana, somando-se pelo menos 300 minutos de atividades físicas por semana. Poucos estudos sobre o nível de atividade física foram encontrados com amostras de crianças e adolescentes brasileiros. Objetivo: Esta pesquisa tem como objetivo a aplicação de um questionário para avaliar o nível de atividade física realizada e suas correlações com estágios da puberdade e índice de massa corporal (IMC) em adolescentes saudáveis matriculados na rede municipal de ensino da cidade de Taubaté, SP, Brasil. Métodos: Foi realizado um estudo transversal por meio de aplicação de um questionário (IPAQ) para avaliar o nível de atividade física e sua correlação com peso, altura e IMC de 202 adolescentes saudáveis. Resultados: O grupo de 15 a 17 anos, considerado pós-púbere nesta pesquisa, apresentou tempos significantemente maiores do que os demais grupos, quanto à resposta da questão 4b (p = 0,002), que indaga sobre o tempo total gasto sentado durante um dia de final de semana. Conclusão: O grupo de 9 a 11 anos, considerado pré-púbere nesta pesquisa, apresentou números significantemente maiores do que os demais grupos quanto às atividades lúdicas moderadas.Descritores: atividade física; exercício; adolescente.

Use of physical activity and cardiorespiratory fitness in identifying cardiovascular risk factors in male brazilian adolescents

“…According to data from the Brazilian Institute of Geography and Statistics 23 , in the previous 30 years there was a six-fold increase in the prevalence of overweight and obesity among male Brazilian adolescents aged 10-19 years (from 4.1% to 27.6%). Moreover, higher rates of overweight prevalence have also been found in other Brazilian cities, which demonstrates the tendency towards obesity [24][25][26][27][28] . These results reveal lifestyle changes in the Brazilian population, and particularly in boys, due to eating and sedentary behaviors that lead to obesity 29 .…”

Analysis of motor capacities in the maturational stages of female adolescents

“…27 evaluating the level of physical activity performed by adolescents and their correlations with pubertal stages and Body Mass Index (BMI), showed that the post-pubertal present significantly greater times than the pre and pubertal ones, considering that the total amount of time spent sitting during a weekend may favour a sedentary lifestyle and a possible increase body fat in adolescents, only reinforcing a negative association between body weight gain and motor competence in teenagers. It was also found that the association between flexibility and motor competence is uncertain.…”
