Are there gross motor coordination spurts during mid‐childhood?
Santos, Marcos A. M. dos; Baxter‐Jones, Adam; Reyes, Ana C.; Freitas, Duarte; Henrique, Rafael S.; Chaves, Raquel N.; Bustamante, Alcibíades; Tani, GoObjectives: 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...
Familial resemblance in gross motor coordination. The peruvian sibling study on...
Valdívia, Alcibíades B.; Henrique, Rafael S.; Pereira, Sara; Chaves, Raquel N.; Tani, Go; Freitas, Duarte; Prista, Antonio; Stodden, David F.Background: The development of gross motor coordination (GMC) is governed by biological and environmental factors whose effect sizes are still unclear. Aim: To investigate sibling resemblance in GMC, as well as biological and environmental correlates of GMC among Peruvian children. Materials and methods: The sample comprised 1256 biological siblings (6–15 years old), from three geographical areas of Peru. GMC w...
Genotype by sex and genotype by age interactions with sedentary behavior: the P...
Santos, Daniel M. V.; Katzmarzyk, Peter T.; Diego, Vincent P.; Blangero, John; Souza, Michele C.; Freitas, Duarte L.; Chaves, Raquel N.Sedentary behavior (SB) expression and its underlying causal factors have been progressively studied, as it is a major determinant of decreased health quality. In the present study we applied Genotype x Age (GxAge) and Genotype x Sex (GxSex) interaction methods to determine if the phenotypic expression of different SB traits is influenced by an interaction between genetic architecture and both age and sex. A to...
