ABSTRACT
Abstract Objective: Summarize the effects of interventions designed to promote physical activity during elementary school recess in children between 5 and 10 years old. Effective school interventions for children can promote physical activity and healthy behaviors. Methods: PubMed, Scopus, Bireme, SciELO, Web of Science, PsychINFO, Proquest, Physical Education Index, Sports Discus, and Eric databases were included in the data search. Original intervention articles on physical activity that used regression methods, published between 2000 and 2019 in English, Portuguese and Spanish were analyzed. Analyses were performed in 2019. Outcomes were organized according to the direction of the association by independent variables. Ten articles were considered eligible for data extraction and evaluation. Results: Several strategies were used including playground markings, demarcation of physical activities zones, group activities, availability of sports equipment and facilities. Most of the studies were conducted in the United States. Recess periods ranged from 20-94 min per day and intervention time ranged from 6 weeks to 2 years. Recess duration and intervention effects were positively associated with physical activity. Gender (girls) and age (oldest) were negatively associated with physical activity during recess. Conclusions: Interventions based on modifications of school environment such as playground markings demarcation of physical activities zones, group activities, availability of sports equipment and facilities are cheap and cost-effective for increasing physical activity in school recess.

ABSTRACT This study aimed at evaluating the association between class context and the teacher's behavior with the physical activity (PA) level of Elementary School students during Physical Education (PE) classes. Eighteen PE classes from six schools were assessed. Class context and the teacher's behavior were measured based on systematic observation, that is, by using the System for Observing Fitness Instruction Time (SOFIT), whereas the students' PA level was measured with accelerometry. Data were treated with descriptive statistics and shown as the percentage of the class time spent in sedentary behavior and at different PA levels. The association between class context and the teacher's behavior with different PA levels was assessed by applying binary logistic regression. The percentage of students with regard to the structured games (35.8%), skill practice (23.2%) and management (21.7%) represented 80.7% of PE class total time. General instructions (45.5%), management (28.7%) and observation (18.3%) were the most frequent teacher's types of behavior seen. It was found that the percentage of time students spent in sedentary behavior and at different PA levels during PE classes varied according to the class context and the teachers' behavior.
RESUMO O objetivo deste estudo foi testar a associação entre o contexto da aula e o comportamento do professor com o nível de atividade física (AF) de escolares dos anos iniciais do ensino fundamental durante aulas de educação física (EF). Foram avaliadas 18 aulas de EF de seis escolas. O contexto da aula e o comportamento do professor foram avaliados por meio de observação sistemática (SOFIT) enquanto o nível de AF dos escolares foi mensurado por acelerometria. Os dados foram tratados pela estatística descritiva e apresentados como proporção do tempo da aula em comportamento sedentário e nos diferentes níveis de AF. A associação entre contexto da aula e comportamento do professor com os diferentes níveis de AF foi testada pela regressão logística binária. Os escolares passaram mais tempo durante a aula de EF em AFs de intensidade leve (40,8%) e vigorosa (40,9%). A proporção do tempo da aula destinado aos contextos jogo estruturado (35,8%), prática de habilidades (23,2%) e gerenciamento (21,7%) representou 80,7% to tempo total. Os comportamentos mais frequentes do professor foram: instruções gerais (45,5%), gerenciamento (28,7%) e observando (18,3%). Verificou-se que a proporção do tempo dos escolares em comportamento sedentário e nos diferentes níveis de AF durante a aula de EF variaram de acordo com o contexto da aula e o comportamento do professor.
