Introduction: the body image is constituted by psychic and cultural aspects elaborated by the subject. It results in satisfaction or dissatisfaction, which can be promoted or intensified by peer pressure on ideals of body image.Objective: to compare the prevalence rates of body dissatisfaction between Brazilians and Portuguese underweight, and to analyze the association of this variable with the social context,...
This study aimed to evaluate the relationship between objectively measured total sedentary time and academic achievement (AA) in Portuguese children. The sample comprised of 213 children (51.6% girls) aged 9.46 ± 0.43 years, from the north of Portugal. Sedentary time was measured with accelerometry, and AA was assessed using the Portuguese Language and Mathematics National Exams results. Multilevel linear regre...
Objective: This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination.Methods: This study included 596 elementary school children aged 9 to 12 years (218 females - 47.1%). Weight, height, and waist circumference were objectively measured by standar...
Introduction: This thesis focuses on the role of motor coordination in children’s healthrelated behaviours and cognitive outcomes. Therefore, this study explores the relationships between motor coordination (MC) and body composition, sedentary behaviour (SB) and academic achievement (AA) in elementary school children. This work presents four papers in the body of the thesis and two papers in the annexes section...
Background Several studies have addressed mothers’ perceptions of their children’s weight status; however, there is no investigation on Portuguese children (a country with one of the highest levels of children’s overweight and obesity in Europe).

We aimed to evaluate the relationship between gross motor coordination (MC) and academic achievement (AA) in a sample of Portuguese children aged 9–12 years. The study took place during the 2009/2010 school year and involved 596 urban children (281 girls) from the north of Portugal. AA was assessed using the Portuguese Language and Mathematics National Exams. Gross MC was evaluated with the Körperkoordination T...
Em idade escolar, a manutenção de níveis adequados de atividade física visa sobretudo o crescimento e desenvolvimento saudável e normal, para além da criação de hábitos de atividade física que se irão prolongar ao longo da vida. As escolas são locais com potencial para serem promovidos comportamentos saudáveis. No contexto escolar, o recreio é reconhecidamente um tempo e um espaço importante no âmbito da promoç...
Objectives: This study was conducted to evaluate the relationship between objectively measured sedentary behavior (SB) and motor coordination (MC) in Portuguese children, accounting for physical activity (PA), accelerometer wear time, waist-to-height ratio, and mother’s education level. Methods: A cross-sectional school-based study was conducted on 213 children (110 girls and 103 boys) aged 9–10 in the north of...
Os benefícios da atividade física em crianças e adolescentes são bem conhecidos e estão bem fundamentados na literatura. Em idade escolar, a manutenção de níveis adequados de atividade física visa sobretudo o crescimento e desenvolvimento saudável e normal, para além da criação de hábitos de atividade física que se irão prolongar ao longo da vida. As escolas são locais com potencial para serem promovidos compor...
Objectivo: A flexibilidade é um componente importante da aptidão física, podendo ser definida como a maior amplitude fisiológica de movimento para a execução de um gesto qualquer. Contudo, há falta de estudos científicos que relacionem esta componente da aptidão física com a obesidade. O objectivo deste estudo foi verificar a prevalência de crianças dentro da zona saudável nos testes de flexibilidade (senta e a...
