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...

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 ...
Phytocannabinoids Pharmaceutical Potential
Pereira, Pedro; Correia-da-Silva, Georgina; Sousa e Silva, PauloCannabis sativa L. is a plant used for therapeutic purposes, although it is widely known for its potential abuse. This plant can produce more than 500 chemical substances, including 100 different phytocannabinoids. These substances can act directly in a specific receptor and/or interact with the endocannabinoid system, regulating physiological effects such as analgesia, muscle relaxation, immunosuppression or a...

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...
