Resumo(s)
O objetivo deste trabalho foi verificar diferenças no somatótipo, na maturidade e no tempo despendido em atividade física e comportamentos sedentários entre estudantes do sexo masculino e feminino, ao longo dos três momentos de avaliação. A amostra foi composta por 24 adolescentes do sexo feminino e 22 adolescentes do sexo masculino, avaliados em três momentos de avaliação e divididos por 3 grupos. O grupo 1 iniciou o estudo com 10, o grupo 2 iniciou com 11 e o grupo 3 iniciou com 12 anos. Obteve-se a antropometria de acordo com o ISAK (Stewart et al., 2011), a atividade física através do questionário (QAPACE) e a maturidade através das equações de Mirwald et al. (2002). Verificou-se que o tempo semanal despendido em atividade física não cumpria as recomendações da OMS. Quando comparados entre sexos, e para a mesma idade decimal, as raparigas são maturacionalmente avançadas, e atingem o PVA aos 12 anos enquanto os rapazes apenas o atingem aos 14. O tipo morfológico parece ser mais estável nas raparigas. Não se registaram alterações significativas, em ambos os sexos, do tempo despendido em atividade física. Os comportamentos sedentários oscilaram tanto entre os sexos como dentro de cada grupo, não apresentando resultados consensuais.
This longitudinal study aims to assess the somatotype and maturity alterations, physical activity and sedentary behaviors in children and adolescents over time. Twenty-four girls and twenty-two boys were included in the study and were divided in three groups and evaluated in three different moments. The group 1 began the study with 10 years, the group 2 with 11 years, and the group 3 with 12 years old. The anthropometry was collected based in ISAK (Stewart et al., 2011), the physical activity based on QAPACE questionnaire and the maturity evaluation through Mirwald et al, (2002) equations. It was noticed that time spent on physical activity during the week doesn’t accomplish the WHO recommendations. Comparing boys and girls between genders and for the same decimal age it was noticed that the girls were maturity advanced, reaching the PHV to 12 years old while the boys just catching it up to 14 years old. The morphotype seems to be more stable in the girls than in the boys during the follow-up. It wasn’t recorded significant alterations in both sexes for the time spent in physical activity. The sedentary behavior varied between sexes as inside of each group without consistent results.
