- Associations between body mass index, physical activity, perceived school competence, and academic performance in Portuguese elementary studentsPublication . Rebelo, Miguel; Serrano, João; HONÓRIO, SAMUEL; Santos, Jorge; Marques, Catarina; Silva Batista, Marco AlexandreBackground/Objectives: Childhood is a critical stage for consolidating health-related habits that shape physical, cognitive, and socio-emotional development. Regular physical activity has been linked to fitness and academic outcomes, while high body mass index (BMI) may hinder school performance. This study examined associations between BMI, perceived school competence, academic performance, and weekly physical activity volume in Portuguese elementary students, addressing a gap in national evidence compared with international studies. Methods: A cross-sectional correlational design was adopted with 531 children (M = 9.13 years) from 10 public schools. BMI was calculated from anthropometric measures, weekly physical activity was self-reported, perceived competence was assessed with Harter’s Self-Concept Scale (Cronbach’s α = 0.797), and academic performance was obtained from school records. Analyses included Pearson correlations, ANOVA with Scheffé post hoc, and multiple regression, with exact significance values reported. Results: Higher BMI was negatively associated with perceived competence and academic achievement, while regular physical activity, particularly 4–6 h per week, was linked to better results in Portuguese and mathematics. Associations were modest (r = 0.18–0.32; R2 = 0.12). Regression showed physical activity (β = 0.093, p = 0.033) and perceived competence (β = 0.126, p = 0.004) predicted academic performance, whereas BMI was not (β = −0.028, p = 0.524). The near-zero correlation with environmental studies suggests subject-specific influences. Conclusions: Adequate BMI and regular physical activity are associated with better academic performance. The role of perceived competence is theoretically inferred as a potential mediator, but not formally tested. Findings highlight the interplay of physical, cognitive, and psychosocial factors. Structured school-based activity programs of 4–6 h weekly may promote both health and learning.
- Literatura infantil em multiformato: Museu da Seda da APPACDM de Castelo BrancoPublication . Sousa, Célia; Gil, HenriqueEste trabalho propõe uma reflexão acerca de como o património pode ser comunicado para todos dentro e fora do espaço físico do museu, tendo como princípio a equidade, de forma a sensibilizar para a diversidade humana, através da comunicação para todos. Para tal, fundamenta-se nos conceitos de Desenho Universal, equidade e diferentes formatos de comunicação, relacionando-os com a nova definição de Museus pelo Conselho Internacional de Museus. Os resultados que ora se apresentam evidenciam que a comunicação multiformato auxilia na comunicação do património, podendo ser utilizado de muitas formas, consoante ao objetivo que se pretende atingir. Observa-se a sensibilização de todos para a aprendizagem acerca da diversidade humana, bem como do entendimento do conceito de "para todos". A criação de um livro infantil multiformato é o corolário de todo o trabalho desenvolvido no Museu da Seda para que seja acessível "para todos", com particular atenção para as crianças
- Skeletal age assessed by Greulich-Pyle: Intra-observer and inter-observer agreement among male pubertal tennis playersPublication . Celis-Moreno, Jorge M.; Martinho, Diogo V.; Silva, Manuel J. Coelho; Fragoso, Isabel; Ribeiro, Luís P.; Gouveia, Élvio R.; Oliveira, Tomás; Santos, João Gonçalves; Tavares, Oscar M.; Cayolla, Ricardo R.; Mendes, Pedro Duarte; Konarski, Jan M.; Malina, Robert M.; Myburgh, Gillian K.; Cumming, Sean P.; Sherar, Lauren B.; Duarte-Mendes, PedroThe assessment of biological maturation is a central topic in pediatric exercise sciences. Skeletal age (SA) reflects changes in each bone of the hand and wrist from initial ossification to the adult state. This study examined intra-observer and inter-examiner agreement is Greulich-Pyle (GP) assessments of SA in 97 male tennis players 8.6–16.8 years of age. Two observers independently examined all films on two occasions using the GP method. The SA of each bone was evaluated. The mean and median of SAs assigned for each bone was the individual SA for each participant. The calculation was exclusively based on the bones that were not skeletally mature. Intra-observer mean differences were significant for several bones with better results by the experienced examiner (observer B). Comparisons between SA values of the two independent observers indicated significant differences for the ulna, metacarpals II and III, and distal phalanx V. Nevertheless, the magnitude of the bone-specific differences was small, perhaps trivial. Differences in individual SA values of the tennis players based on the non-mature bones of the hand-wrist were negligible based on the mean (0.04±0.39, t = 0.321, p = 0.749) or the median (0.05±0.58, t = 0.007, p = 0.994). Nevertheless, the current study confirmed examiners as a source of error in the estimation of SA using the Greulich-Pyle method and highlighted the importance of calculating SAs based on non-mature bones among adolescent players.
