    Biological and environmental influences on motor coordination in Peruvian children and adolescents
    (Edições Universitárias Lusófonas, 2021) Pereira, Sara Isabel Sampaio; Bustamante, Alcibíades; Santos, Carla Sofia Pinho dos; Hedeker, Donald; Tani, Go; Silva, Rui Manuel Garganta da; Vasconcelos, Maria Olga Fernandes; Baxter-Jones, Adam; Katzmarzyk, Peter T.; Maia, José António Ribeiro; Faculdade de Educação Física e Desporto
    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. Environmental influences included geographical region and school characteristics. Gross-motor coordination was tested with the Körperkoordinationstest für Kinder and the data analyzed by multilevel logistic regression. Results showed a high prevalence of below normal GMC scores. Sex, age, geographical area, biological maturation, BMI (normal versus overweight/obesity), and stunting were all significant predictors of GMC. There was also an interaction between age, sex, and geographical area indicating that older girls who lived at sea-level and high-altitude were more likely to display below normal GMC scores. The school context was less important in predicting GMC problems than the interplay between biological characteristics and geographical region. These results suggest that early identification, as well as educational and pediatric care interventions, are of importance in reducing below normal GMC among Peruvian children and adolescents.

    Discriminant analysis of anthropometric and training variables among runners of different competitive levels
    (Edições Universitárias Lusófonas, 2021) Thuany, Mabliny; Souza, Raphael Fabricio; Hill, Lee; Mesquita, João Lino; Rosemann, Thomas; Knechtle, Beat; Pereira, Sara Isabel Sampaio; Gomes, Thayse; Faculdade de Educação Física e Desporto
    The purpose of this study was to investigate the multivariate profile of different types of Brazilian runners and to identify the discriminant pattern of the distinct types of runners, as a runners' ability to self-classify well. The sample comprised 1235 Brazilian runners of both sexes (492 women; 743 men), with a mean age of 37.94 ± 9.46 years. Individual characteristics were obtained through an online questionnaire: Sex, age, body height (m) and body mass (kg), socioeconomic status, and training information (i.e., self-classification, practice time, practice motivation, running pace, frequency and training volume/week). Multivariate analysis of variance was conducted by sex and the discriminant analysis was used to identify which among running pace, practice time, body mass index and volume/training could differentiate groups such as "professional athletes", "amateur athletes" and "recreational athletes". For both sexes, running pace was the variable that better discriminated the groups, followed by BMI and volume/week. The practice time is not a good indicator to differentiate runner's types. In both sexes, semi-professional runners were those that better self-classify themselves, with amateur runners presenting the highest classification error. This information can be used to guide the long-term training, athlete's selection programs, and to identify the strengths and weaknesses of athletes.
