- Grip strength, fall efficacy, and balance confidence as associated factors with fall risk in middle-aged and older adults living in the communityPublication . Marconcin, Priscila; Martinho, Estela; Serpa, Joana; Nascimento, Marcelo; Flôres, Fábio; Santos, Vanessa; Loureiro, Vânia; HONÓRIO, SAMUEL; Marconcin, PriscilaBackground: Falls are a major public health concern among older adults, often resulting in injury, functional decline, and reduced quality of life. While handgrip strength (HGS), fall efficacy, and balance confidence have individually been associated with fall risk, their com bined predictive value is still underexplored, particularly in physically active older adults. This study aimed to investigate the relationship between HGS, fall efficacy, and balance confidence and their association with fall risk in community-dwelling older adults engaged in regular exercise programs; A cross-sectional study was conducted with 280 participants aged 55 and over from community exercise programs near Lisbon, Portugal. Fall risk was assessed through self-reported falls in the past 12 months. HGS was measured with a dynamometer, fall efficacy using the Falls Efficacy Scale-International (FES-I), and balance confidence using the Activities-specific Balance Confidence (ABC) Scale. Statistical anal yses included Spearman correlations and binary logistic regression. Results: Falls were reported by 26.4% of participants. Fall efficacy and balance confidence were significantly associated with fall history, while HGS was not. Fall efficacy was significantly associated with increased fall risk, as indicated by the odds ratio (OR = 3.37, p < 0.001), while balance confidence was negatively associated (OR = 0.95, p < 0.001). HGS was positively correlated with balance and confidence but not with fall incidence. Conclusions: Psychological factors, particularly fall efficacy and balance confidence, play a critical role in fall risk among physi cally active older adults. However, this study included physically active middle-aged and older adults living in the community, which should be considered when interpreting the generalizability of the results. These findings support the integration of simple, validated psychological assessments into fall prevention strategies in community settings.
- 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.
- Tipos de atividade física e hábitos alimentares entre os membros da igrejaPublication . Honório, Samuel; Batista, Marco; Santos, Jorge; Petrica, Joao; Farinha, Carlos; Vieira, Fernando; Rebelo, Miguel; Silveira, Paulo; Silva, Maria Raquel G.; Serrano, João; Honório, Samuel.Introdução: A atividade física adequada e os hábi-tos alimentares estão diretamente ligados e contribuem de forma posi-tiva na prevenção de doen-ças hipocinéticas e auxílio no tratamento de doenças como a obesidade, asma brônquica, diabetes e distúrbios do movimento. Objetivo: Identificar e analisar os comportamen-tos evidenciados por esta padres e freiras de acordo com os tipos atividade física praticada e hábitos alimentares. Participaram 85 indivíduos com idades compreendidas entre os 26 e os 90 anos de idade (54.69±16.33 anos). Des-tes participantes, 48 (56,5%) são do género masculino e 37 (43,5%) do género feminino. Métodos: Trata-se de um estudo observacional, descritivo e de corte trans-versal. Os participantes foram informados e escla-recidos sobre o estudo e a forma de preenchimento dos questionários com o respetivo pedido formal de consentimento informado. Foi utilizado um questio-nário intitulado: “Rotinas de Vida Diária, os Hábitos de Lazer, Atividade física e Saúde de membros da Igreja”. O questionário foi construído originalmente recorrendo a outros ques-tionários validados para avaliação de rotinas de vida, hábitos alimentares, atividade física e estados de saúde. Resultados: Os participan-tes apresentaram compor-tamentos, quer no âmbito da atividade física, em termos do número de vezes que a praticam como o tempo despendidos nestas, quer no âmbito dos hábitos alimentares favo-ráveis, demonstrando preocupação na quantida-de de ingestão e tipo de alimentos consumidos. Discussão: De acordo com os resultados obtidos, ver televisão e usar as Redes Sociais foram as atividades semanalmente mais prati-cadas pelos membros da igreja, participantes no presente estudo. Conclusão: Dado o contex-to social e de missão espe-cífica de vida, os membros da igreja avaliados apre-sentaram comportamentos favoráveis a um nível ade-quado de atividade física, bem como, hábitos alimen-tares, na sua maioria, favo-ráveis a um estilo de vida saudável.
