This study aimed to (1) estimate age-at-mid-growth spurt (age-at-MGS) in Portuguese boys from two different regions—the Azores islands and Viana do Castelo, and (2) identify spurts in a variety of physical fitness (PF) components aligned by age-at MGS in the two samples. A total of 176 (Azores, n = 91; Viana do Castelo, n = 85) boys aged 6 years old were followed annually to 10 years of age. Age-at-MGS and spur...
This study investigated the associations between biological and environmental factors and gross-motor coordination (GMC) in Peruvian children and adolescents. The sample comprised 7401 boys and girls, aged 6–14 years, recruited from three geographical regions: sea-level, Amazon and high-altitude. Biological variables included age, sex, height, BMI, physical fitness, stunting, and maturational status. Environmen...
Objectives: The aims of this study were (1) to identify the timing of the mid growth spurt (MGS) in stature in children and (2) to identify gross motor coordina tion (GMC) spurts when aligned by the age of attainment of the MGS (aMGS). Methods: Stature, weight, and GMC were measured in 245 Portuguese children followed annually from 6 to 10 years. GMC was assessed and to estimate children's MGS in stature as wel...

This study aimed to provide height, body mass, BMI and waist circumference (WC) growth centile charts for school-children, aged 4–17 years, from central Peru, and to compare Peruvian data with North-American and Argentinean references. The sample consisted of 8753 children and adolescents (4130 boys and 4623 girls) aged 4 to 17 years, from four Peruvian cities: Barranco, La Merced, San Ramón and Junín. Height, ...
This study aims at: 1) describing models for developmental changes and interindividual differences in gross motor coordination (CoM); 2) verify the presence of gender effects; 3) and test the importance of BMI and physical activity level in motor coordination (CoM) development. Sample size comprises 285 children (143 boys and 142 girls). Motor coordination was evaluated with the test battery "Körperkoordination...
Objectivo: Construir cartas centílicas e respectiva distribuição de valores da Coordenação Motora em crianças açorianas dos 6 aos 11 anos segundo o género e idade. Metodologia: A amostra é constituída por 2359 meninas e 2365 meninos da Região Autónoma dos Açores. A Coordenação Motora foi avaliada através da bateria KTK, que compreende quatro provas: equilíbrio à retaguarda, saltos laterais, saltos monopedais e ...
O objetivo do estudo é caracterizar o desenvolvimento coordenativo em crianças açorianas dos 6 aos 10 anos em função do sexo e estimar a estabilidade da mudança intraindividual nas diferenças interindividuais ao longo dos quatro anos. A amostra de 285 crianças (143 meninos e 142 meninas) é proveniente do estudo longitudinal-misto da Região Autônoma dos Açores (RAA). A coordenação motora (CoM) foi determinada co...
Este tutorial pretende apresentar, de modo didáctico, uma forma alternativa de análise de dados sobre os níveis de actividade física de crianças a partir da modelação hierárquica ou multinível. São mencionadas as diferentes etapas da modelação, os resultados são interpretados com base nos output's do software utilizado – o HLM 6.02. Em cada etapa do percurso são lançadas as hipóteses mais importantes em grau de...
