[Recommendations for physical activity and health: consensus, controversies, and ambiguities]. / Recomendações para atividade física e saúde: consensos, controvérsias e ambiguidades.

OBJECTIVE: To compare the results of physical activity (PA) classification according to five international guidelines (American College of Sports Medicine, Institute of Medicine, Advisory Committee on International Physical Activity Questionnaire, World Health Organization, and European Union). METHODS: Cross-sectional study with 52 779 adults of both sexes, living in state capitals and the Federal District, selected using probability sampling. Data about duration, intensity, and frequency of weekly PA were obtained from a yearly survey conducted by the Health Ministry of Brazil (Risk and Protection Factors for Chronic Diseases Telephone Surveillance System-VIGITEL). RESULTS: The percent of participants classified as inactive by the five recommendations was similar. Among those who reported having engaged in PA, 45% were classified in the same activity level by all five guidelines (24.8% as insufficiently active, 10.6% as active, and 9.1% as very active). For the additional 55% who reported having engaged in PA, different classifications were obtained, ranging from insufficiently active to very active depending on the guideline. CONCLUSIONS: Nuances in the criteria used for each guideline translated into differences in classification of PA. Even though the overall goals of all guidelines are the same, the lack of agreement regarding the minimum recommended amount of PA impacts the development of policies to promote PA.

Associations Between Fundamental Motor Skill Domains and Physical Fitness Components in 5-11-Year-Old Children.

High competence in fundamental motor skills (FMS) and adequate physical fitness (PF) levels are a solid foundation for acquiring an active and healthy lifestyle during childhood and adolescence. In this cross-sectional study, we aimed to compare gender and age groups and identify correlations between FMS and PF in young elementary school students. We used a structured questionnaire to gather sociodemographic information from parents, and we characterized the children's economic profile with the Brazil Social Economic Status Criterion. We collected FMS data using the Furtado-Gallagher Children Observational Movement Pattern Assessment System (FG-COMPASS), and we used the Brazil Sports Project Battery Test to measure PF levels. Statistical analyses involved descriptive data and inferential tests to determine group differences in FMS and PF levels. Hierarchical regression helped identify the associations between FMS and PF, as controlled by sociodemographic factors. Participants were 720 students (and parents) of both genders (383 girls, 337 boys; M age = 8.8, SD = 1.52 years) from grades 1 to 5 in an elementary school in a municipality in the western region of the Paraná state in Brazil. The results showed significant differences in children's motor skills and PF based on gender and age. The hierarchical regression model showed different combinations of flexibility, abdominal resistance, upper limb strength, agility, speed, and lower limb strength, which explained 33.7% of the variability in the global FMS index, 41% of the variability in manipulative skills, and 12.7% of the variability in locomotor skills. In addition, there was a positive association between FMS and PF related to neuromuscular development for both sexes, regardless of age.
