Skeletal age assessed by Greulich-Pyle: intra-observer and inter-observer agree...
Celis-Moreno, Jorge M.; Martinho, Diogo V.; Coelho-e-Silva, Manuel J.; Fragoso, Isabel; Ribeiro, Luís Pedro; Gouveia, Élvio R.; Oliveira, TomasThe 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 ...

Skeletal Maturity in Adolescence
Pinheiro, João; Ribeiro, Luís Pedro; Teixeira, Diana; Magalhães Ribeiro, Anabela; Coelho-e-SilvaPublisher Copyright: © 2025 by the authors.; Background/Objectives: Bone maturation and development are crucial for growth and development, especially in children and adolescents; however, some qualitative methods, such as Greulich & Pyle, do not provide accurate data. Our aim is to verify whether skeletal age (SA) can predict and correlate with bone mineral content (BMC), bone mineral density (BMD), and body c...
Ultrasonographic evaluation of the Patellar Tendon in cyclists, volleyball play...
Pissarra, Ângela; Ribeiro, Luís Pedro; do Espírito Santo Rodrigues, Sónia IsabelThis study was based on the ultrasound evaluation of the patellar tendon dimensions in the anteroposterior and transversal approaches in sports practitioners (cyclists and volleyball players) and non-sports practitioners. Relationships between the patellar tendon length, width, and thickness with gender, age, height, the dominant limb, and level of physical activity were evaluated. The samples included cyclists...
Interpretation of many-valuedness in quality-of-life instruments
Ribeiro, Luís Pedro; Eklund, Patrik; Gomes Alves Ferreira, Maria Augusta; Magalhães Ribeiro, Anabela de; Farinha, Maria Conceição; Paiva, Maria AdelaideAssessment instruments for functioning in general and quality of life in particular often involve discrete scales with three, four, or five values, or Visual Analogue Scales (VAS) with a range 0–100. VAS scales often need to be downsized and discretized using intervals or clusters. Cutoff points for these intervals/clusters need to be carefully selected and justified. Our objective was to underline the importan...
Bone mineral density and body composition among individuals who practice sports...
Pinheiro, João; Ribeiro, Luís Pedro; Coelho-e-Silva, ManuelThe purpose of this study was to evaluate indicators of bone health associated with sports practice in male adolescents using dual-energy X-ray absorptiometry (DXA) to measure bone mineral content (BMC), density (BMD), and body composition (BC) for the whole body (WB) and specific regions. This cross-sectional study involved 65 individuals (18–35 years). Athletes had higher BMD for WB (1.064 ± 0.121 g/m−2) than...
The Relationship between Lifestyle and Academic Success of Medical Imaging and ...
Gaudêncio, Nélia; Rodrigues, Sónia Isabel; Almeida, Rui Pedro; Santos, Fábio; Ribeiro, Luís Pedro; Abrantes, António; Bárbara, Ana CatarinaObjective: To evaluate the relationship between the lifestyle of students of the Degree in Medical Imaging and Radiotherapy (MIR) and their academic success. Materials and Methods: Data were collected through a set of instruments: sociodemographic questionnaire, "Lifestyles Questionnaire" and "Lifestyle Characterization Questionnaire", distributed online to students attending the four curricular...

Sousa-e-Silva, Paulo; Coelho-e-Silva, Manuel J.; Celis-Moreno, Jorge M.; Costa, Daniela C.; Martinho, Diogo V.; Ribeiro, Luís Pedro; Oliveira, TomasBackground Skeletal age (SA) is an estimate of biological maturity status that is commonly used in sport-related medical examinations. This study considered intra-observer reproducibility and inter-observer agreement of SA assessments among male tennis players. Methods SA was assessed with the Fels method in 97 male tennis players with chronological ages (CA) spanning 8.7–16.8 years. Radiographs were evaluated ...
Interrelationship between muscle fitness in childhood and bone mineral density ...
Barbosa, Cynthia C. L.; da Costa, Julio C.; Romanzini, Catiana L. P.; Batista, Mariana B.; Blasquez-Shigaki, Gabriela; Fernandes, Rômulo A.Background This study was aimed to examine the relationship between muscular fitness indicators in childhood and areal bone mineral density (aBMD) in adulthood and to verify whether the relationship is mediated by performance on muscular fitness indicators in adulthood. Methods A sample of 138 healthy adults (69 males; 22.3 years) were followed after a previous assessment at the age of 7–10 years. Stature, body...
