Thus, the objective of this project is to verify a school physical activity intervention on executive functions and the relationships with cardiorespiratory fitness and motor coordination. This will be a randomized control trial in accordance with the Consort - Statement, including 118 children of both sexes; 60 in an experimental group and 58 in a control group. The children will follow their usual school routines, including Physical Education classes as part of the curriculum. The experimental group will also participate in an intervention for 12 weeks after school. The intervention will include three weekly physical exercise sessions, lasting between 50 and 60 minutes. The sessions will consist of activities involving games, sports, dance with a focus on aspects of motor coordination and cardiorespiratory fitness, as well as cognitive games. Assessments will be carried out at baseline, after 12 weeks of intervention and after the follow-up period. The students will undergo measurements of body mass and height, as well as nutritional classification using the body mass index (BMI). Following this, a general motor coordination test (KTK), a cardiorespiratory aptitude test (Léger), and tests to assess executive functions (Stroop and Corsi Block) will be applied. Data distribution will be verified using the Shapiro-Wilk's test. The comparisons between different moments (baseline, after 12 weeks, and at follow-up) will be performed using repeated measures ANOVA. Sphericity will be checked by Mauchly's test followed by the Greenhouse- Geisser correction when necessary. To identify differences, the Bonferroni correction will be applied. The significance level will be set at 5% (P\\<0.05).", 'detailedDescription': 'During childhood, cognitive aspects of the prefrontal cortex are in the maturation phase. This process is associated with improvements in executive functions, in a continuous process, and although differentiated by its multiple aspects, it seems to correspond with the development peaks of the prefrontal cortex, which occur between 7 and 9 years of age. In addition to the biological alterations arising from the growth and development of the brain, physical activity performed regularly indicates a simple and effective way to improve the executive functions of children. Contreras-Osorio and colleagues stated that physical activity performed at moderate and vigorous intensities is positively related to working memory, reaction time, executive attention, cognitive flexibility, and planning in children and adolescents aged 10 to 12 years. Other authors highlight that activities involving cardiorespiratory fitness and motor coordination provide an increase in cognitive performance, with improvements in planning capacity, memory, self-control, and value judgment, among other fundamental components for social interaction and academic performance In a previous study, Visier-Alfonso and colleagues evaluated 186 school-age children aged 9 to 11 years and demonstrated positive effects on cardiorespiratory fitness, with increased physical activity, and positive changes in inhibitory control, working memory, and brain structure. Additionally, good levels of motor coordination are associated with complex movements and sport-specific skills, and are also essential for the development of higher levels of cognitive function. The relationships between motor skills and executive functions during childhood are based on coactivation events between the prefrontal cortex, the cerebellum, and the basal ganglia during different motor and cognitive tasks, especially when the task is complex, is a new task, or requires speed and concentration. This is because neural regions typically associated with cognitive operations can also be recruited during the performance of motor tasks.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '11 Years', 'minimumAge': '8 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\nHealthy\n\nNeurotypical.\n\nExclusion Criteria:\n\nClinical or historical of cardiovascular disease\n\nHypertension\n\nInsulin-dependent diabetes mellitus\n\nNeurodiversity\n\nNot be taking any drugs\n\nCannot participated in sports practices'}, 'identificationModule': {'nctId': 'NCT06496503', 'briefTitle': 'Effect of a School Intervention With Physical Activity on Executive Functions', 'organization': {'class': 'OTHER', 'fullName': 'State University of Londrina'}, 'officialTitle': 'Effect of a School Intervention With Physical Activity on Executive Functions and Relationships With Cardiorespiratory Fitness and Motor Coordination: Randomized Clinical Trial', 'orgStudyIdInfo': {'id': 'UEL'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Experimental group', 'description': 'The children included in the experimental group will undergo 12 weeks of physical activity sessions, and it is mandatory that all children complete a minimum of two weekly sessions of physical activity for 50-60 minutes.
