The aim of this study was to verify the association between school environment and accumulated physical activity in Brazilian adolescents. This is a study with secondary data from sample 1, from the third edition of the National School Health Survey, a study carried out with 102.072 children and adolescents enrolled in the ninth school grade. Questions about characteristics of the school environment and the offer of opportunities for physical activity practices were addressed, focusing on information regarding the structure for physical activity and about the regular practice of accumulated physical activities. Variables were organized from the structure of schools and opportunities for the practice of physical activities, while accumulated physical activity was used as the outcome variable. Data were analyzed from a binary logistic regression model, organized in crude and adjusted models, with a significance level of 5%. Data were analyzed from SPSS for Windows, version 22.0. Results indicate that, from the adjustment of variables, there was an association between the practice of accumulated physical activity and the existence of a sports court under conditions of use (OR=1.22, 95%CI=1.18-1.26), or presence of courtyard for use of physical education classes (OR=1.04, 95%CI=1.01-1.06). Association between the offer of varied physical activities, except for physical education classes, and the practice of accumulated physical activity (OR=1.05, 95%CI=1.02-1.08) was identified. Existence of a sports court/courtyard in schools and the offer of extracurricular physical activities are associated with the practice of accumulated physical activity in young Brazilian students.

Flexibility is a health-related physical fitness component that has its importance related to the maintenance of functional independence and achievement of activities of the daily living. This systematic review aims to analyze the existing evidence in the literature regarding physical capacity flexibility in Brazilian children and adolescents. Searches were conducted in the Virtual Health Library, Scientific Electronic Library Online, Sportdiscus databases through the EBSCOhost and Pubmed platform. There were 89,553 articles, of which 69,197 were excluded for duplicity, 20,124 for the title, 160 for the abstract, 56 after a full analysis of the article, remaining 16 articles for the qualitative analysis. Of these, from the reading of references, 57 titles partially eligible for the review were identified, and after the application of the eligibility criteria, there were only 18 for the qualitative analysis. Of the 34 studies included for the qualitative analysis, 25 studies were excluded and nine were included in the review. All articles presented the cross-sectional design and used the sit-and-reach test to assess flexibility. It was evidenced that: a) flexibility has been treated as co-adjuvant in studies with children and adolescents; b) although females have absolute flexibility values greater than the opposite sex, males have higher frequency of subjects that meet the health classification criteria in this variable; c) there is greater prevalence of the use of FITNESSGRAM and PROESP-BR reference standards.

O presente estudo tem como objetivo avaliar a associação entre o comportamento do bullying, variáveis sociodemográficas e a atividade física acumulada em adolescentes escolarizados brasileiros. Trata-se de um estudo com dados secundários, utilizando dados da Amostra 2, da PeNSE 2015 (n = 10926). Para a análise de dados foi utilizada a regressão logística binária para estimar a chance de ocorrência do fenômeno do bullying na forma de Odds Ratio (OR) bruta e ajustada. Para a verificação dos fatores associados ao bullying em adolescentes brasileiros a amostra foi estratificada em “ativos” e “insuficientemente ativos”, de forma a entender o comportamento do bullying entre cada estrato. Observou-se que o sexo masculino apresentou duas vezes mais chances (OR = 1,99; IC95% 1,80 – 2,19) de apresentar este comportamento de bullying quando comparado com o sexo feminino. Verificou-se para o estrato “ativos”, associação entre perpetrar bullying e o sexo masculino (OR = 2,21; IC95% 1,82 - 2,67) e sofrer bullying enquanto auto percepção (OR = 2,45; IC95% 2,05 - 2,93). Para os “insuficientemente ativos”, percebeu-se associação no modelo ajustado entre “perpetrar bullying” e sexo masculino (OR = 1,88; IC95% 1,65 - 2,13). Notou-se que os adolescentes do sexo masculino, que sofriam bullying, tinham mais chance de praticar bullying. Os resultados sugerem ainda que, tanto no grupo “ativo” quanto no grupo de “insuficientemente ativo”, quem perpetra bullying tem mais chance de ter sofrido bullying, sugerindo que o comportamento do bullying é anterior à prática de atividade física.

Cardiorespiratory fitness is an important health status indicator. The purpose of this study was to verify the cardiorespiratory fitness according to age group and gender in children and adolescents from Sergipe, Brazil. It is a cross-sectional study with sample consisting of 195 adolescents of both genders with mean age of 11.75 ± 3.0 years. For the characterization of participants, a questionnaire with age and gender identification designed by researchers was used. Subsequently, participants were submitted to anthropometric evaluation in order to estimate the maturational stage by means of the peak height velocity (PHV). The 20-meter back-and-forth test was used to estimate cardiorespiratory fitness. Two-way ANOVA was applied with sample divided into two groups (“up to 13 years” and “above 13 years”). Polynomial contrast was used to identify the type of tendency for cardiorespiratory fitness, and simple contrast for multiple comparisons. All procedures were performed using SPSS version 22.0 software, considering 5% significance level. In the “over 13 years” group, there was a significant effect on the cardiorespiratory capacity behavior according to “gender” [F(1, 45) = 5.54, p = 0.02, r = 0.33] and “age” [F(4.45) = 3.37, p = 0.02, r = 0.48]. The simple contrast identified increased cardiorespiratory fitness behavior in relation to age groups of 15 and 16 year when compared to the age group of 14 years. It was concluded that gender and age positively influence cardiorespiratory fitness from the maturational reference age in the study group.
