Learning effect on an isokinetic knee strength test protocol among male adolesc...
Costa, Daniela C.; Valente-dos-Santos, João; Celis Moreno, Jorge M.; Sousa e Silva, Paulo; Martinho, Diogo V.; Duarte, João P.; Oliveira, Tomás G.Learning effect occurs when the best performance is not achieved at the earliest trial of a repeated protocol of evaluation. The present study examined, within testing session, the intra-individual variation in an isokinetic strength protocol composed of five reciprocal concentric and eccentric contractions of knee extensors (KE) and knee flexors (KF) among male adolescent swimmers. Additionally, test-retest re...
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 ...
Allometric modeling of wingate test among adult male athletes from combat sports
Coelho-E-silva, Manuel J.; Sousa-E-silva, Paulo; Morato, Vinícius S.; Costa, Daniela C.; Martinho, Diogo V.; Rama, Luís M.; Valente-Dos-santos, JoãoMade available in DSpace on 2021-06-25T10:11:49Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-09-01; Background and objectives: Athletes from combat sports are grouped into a series of weight categories that are intended to promote fair competition. Differences in performance are partly attributable to differences in body size. Consequently, ratio standards in which a performance variable is simply div...
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...
Physiological profile of adult male long-distance trail runners: variations acc...
Oliveira-Rosado, Joana; Duarte, João P.; Silva, Paulo Sousa e; Costa, Daniela; Martinho, Diogo V.; Sarmento, Hugo; Santos, João Valente dosObjective: To describe and identify the importance of different indicators of the aerobic and anaerobic fitness of male ultra-trail runners according to their level of participation (regional or national). Methods: Forty-four male ultra-trail runners were assessed (36.5±7.2 years). They were classified as regional (n=25) and national (n=19). Wingate test was used to assess the anaerobic pathway. A progressive i...
Allometric Modeling of Wingate Test among Adult Male Athletes from Combat Sports
Coelho-e-Silva, Manuel J.; Silva, Paulo Sousa e; Morato, Vinícius; Costa, Daniela; Martinho, Diogo V.; Rama, Luis M.; Valente-dos-Santos, JoãoBackground and objectives: Athletes from combat sports are grouped into a series of weight categories that are intended to promote fair competition. Differences in performance are partly attributable to differences in body size. Consequently, ratio standards in which a performance variable is simply divided by an anthropometric characteristic such as body mass are often used, although this application is not re...
Body composition, strength static and isokinetic, and bone health: comparative ...
Tavares, Óscar M.; Duarte, João P.; Werneck, André O.; Costa, Daniela C.; Sousa-e-Silva, Paulo; Martinho, Diogo; Luz, Leonardo G. O.; Morouço, PedroObjective: To compare tissue composition, total and regional bone mineral content and bone mineral density, static hand grip and knee joint isokinetic strength between amateur soccer players and Control Group. Methods: Cross-sectional study. Air displacement plethysmography was used to estimate body volume and, in turn, density. Body composition, bone mineral content and bone mineral density were assessed for t...
Total and regional bone mineral and tissue composition in female adolescent ath...
Valente-dos-Santos, João; Tavares, Óscar M.; Duarte, João P.; Sousa e Silva, Paulo M.; Rama, Luis M.; Casanova, José M.; Fontes-Ribeiro, Carlos A.Background: Exploring the osteogenic effect of different bone-loading sports is particular relevant to understand the interaction between skeletal muscle and bone health during growth. This study aimed to compare total and regional bone and soft-tissue composition between female adolescent swimmers (n=20, 15.71±0.93 years) and volleyball players (n=26, 16.20±0.77 years). Methods: Dietary intake was obtained usi...
Agreement between dual x-ray absorptiometers using pencil beam and fan beam: in...
Tavares, Óscar M.; Duarte, João P.; Costa, Daniela C.; Sousa e Silva, Paulo; Martinho, Diogo; Lus, Leonardo G. O.; Duarte-Mendes, PedroOBJECTIVE: The current study was aimed to examine intra-individual variation on indicators of bone health in addition to whole-body plus appendicular tissue measurements using two concurrent assessments based on pencil beam and fan beam dual energy X-ray absorptiometry (DXA) systems in adult athletes from several sports. METHOD: Thirty-two male participants (27.6±10.1 years) were measured on anthropometry inclu...

Tavares, Óscar M.; Valente-dos-Santos, João; Duarte, João P.; Póvoas, Susana C.; Gobbo, Luís A. [UNESP]; Fernandes, Rômulo A. [UNESP]Made available in DSpace on 2018-12-11T16:44:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-11-24; Background: A variety of performance outputs are strongly determined by lower limbs volume and composition in children and adolescents. The current study aimed to examine the validity of thigh volume (TV) estimated by anthropometry in late adolescent female volleyball players. Dual-energy X-ray absorpti...
