Intra-observer reproducibility and inter-observer agreement of Fels skeletal ag...
Sousa e Silva, Paulo; Silva, Manuel J. Coelho e; Celis-Moreno, Jorge M; Costa, Daniela C.; Martinho, Diogo V.; Ribeiro, Luís P.; Oliveira, TomásBackground 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 ...
Body composition and grip strength constraints in elite male rink-hockey player...
Ferraz, António; Santos, J. Valente dos; Mendes, Pedro Duarte; Nunes, Célia; Victorino, Samuel Carlos; Silva, Manuel J. Coelho e; Travassos, BrunoRink hockey is a highly specialized and physiological demanding sport with sparse research regarding the game and athletes’ characteristics. A cross-sectional study was developed to characterize the body composition and grip strength of elite male rink hockey players and to establish the relationship between ethnicity on body composition and grip strength. A sample of 100 elite rink-hockey athletes aged 26.59 ±...
A kinematic analysis of the basketball shot performance: impact of distance var...
França, Cíntia; Gouveia, Élvio Rúbio; Silva, Manuel J. Coelho e; Gomes, Beatriz B.Purpose: The aim of the current study was to examine the variation on the kinematic parameters in the basketball shot associated with the shooting distance. Methods: Twenty-seven female adolescent basketball players aged 12.1 ± 0.9 years completed 10 BS trials from a frontal position of 4.75 m and 5.75 m from the basket. Nine anatomical markers were placed on the participants’ dominant side to assess the kinema...
Exercise as a Peripheral Circadian Clock Resynchronizer in Vascular and Skeleta...
Silva, Bruna Spolador de Alencar; Uzeloto, Juliana Souza; Lira, Fábio Santos; Pereira, Telmo; Silva, Manuel J. Coelho e; Caseiro, ArmandoAging is characterized by several progressive physiological changes, including changes in the circadian rhythm. Circadian rhythms influence behavior, physiology, and metabolic processes in order to maintain homeostasis; they also influence the function of endothelial cells, smooth muscle cells, and immune cells in the vessel wall. A clock misalignment could favor vascular damage and indirectly also affect skele...
The jump shot performance in youth basketball: a systematic review
França, Cíntia; Gomes, Beatriz B.; Gouveia, Élvio Rúbio; Ihle, Andreas; Silva, Manuel J. Coelho eThe basketball jump shot (JS) is consensually considered as a high-complexity specific motor skill, with a complex teaching and learning processes involved. The aim of this paper was to conduct a systematic review of the literature on the JS performance among youth basketball players. Methods: The data search was made according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) in th...
Body composition among long distance runners
Rosado, Joana; Duarte, João P.; Silva, Paulo Sousa e; Costa, Daniela C.; Martinho, Diogo V.; Santos, João Valente dos; Rama, Luis M.; Tavares, Óscar M.OBJECTIVE: The current study aimed to examine the body composition of adult male ultra-trail runners (UTR) according to their level of participation (regional UTR-R, vs. national UTR-N). METHODS: The sample was composed of 44 adult male UTR (aged 36.5±7.2 years; UTR-R: n=25; UTR-N: n=19). Body composition was assessed by air displacement plethysmography, bioelectrical impedance, and dual-energy X-ray absorptiom...

Glycated hemoglobin and associated risk factors in older adults
Martins, Raul A.; Jones, John G.; Cumming, Sean P.; Silva, Manuel J. Coelho e; Teixeira, Ana M.; Veríssimo, Manuel T.Background: The aim of this study is to investigate the relationships between HbA1c and other risk factors like obesity, functional fitness, lipid profile, and inflammatory status in older adults. Epidemiological evidence suggests that HbA1c is associated with cardiovascular and ischemic heart disease risk. Excess of body weight and obesity are considered to play a central role in the development of these condi...
Longitudinal Predictors of Aerobic Performance in Adolescent Soccer Players
Valente-dos-Santos, João; Silva, Manuel J. Coelho e; Duarte, João; Figueiredo, António; Liparotti, João; Sherar, Lauren; Elferink-Gemser, Marije T.Background. The importance of aerobic performance in youth soccer is well established. The aim of the present study was to evaluate the contributions of chronological age (CA), skeletal age (SA), body size, and training to the longitudinal development of aerobic performance in youth male soccer players aged 10 to 18 years. Material and Methods. Players (n=83) were annually followed up during 5 years, resulting ...
Prevalence of overweight, obesity, and abdominal obesity in a representative sa...
Sardinha, Luís B.; Santos, Diana A.; Silva, Analiza M.; Silva, Manuel J. Coelho e; Raimundo, Armando M.; Moreira, Helena; Santos, Rute; Vale, SusanaThis study determined the prevalence of overweight, obesity, and abdominal obesity in the Portuguese adults and examined the relationship between above mentioned prevalences and educational level. Body mass, stature, and waist circumference were measured in a representative sample of the Portuguese population aged 18-103 years (n = 9,447; 18-64 years: n = 6,908; ≥ 65 years: n = 2,539). Overweight and obesity co...
