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 ...

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...

Allometric scaling of aerobic fitness outputs in school-aged pubertal girls
Werneck, André O.; Conde, Jorge; Coelho-e-Silva, Manuel J.; Pereira, Artur; Costa, Daniela C.; Martinho, Diogo V.; Duarte, João P.Background: This study aimed to determine the allometric exponents for concurrent size descriptors (stature, body mass and fat-free mass) and also to examine the contribution of chronological age and pubertal status combined with above mentioned size descriptors to explain inter-individual variability in the peak of oxygen uptake (VO2peak) among girls during circumpubertal years. Methods: The final sample inclu...
