Towards a de facto Nonlinear Periodization: Extending Nonlinearity from Program...
Afonso, José; Clemente, Filipe Manuel; Ribeiro, João; Ferreira, Miguel; Fernandes, Ricardo J.Planning is paramount in sport. Among different philosophical approaches to planning, periodization is a highly popular concept that refers to structured training periods with ensuing programs encompassing moments of progressively-loaded training, followed by recovery; it is normally deemed paramount to optimize adaptations and performance. While planning provides generic guidelines, periodization refers to the...
Change in young swimmers’ anaerobic potential in response to taper
Rodrigues Sampaio, António; Ferreira, Francisco; Vilas-Boas, João Paulo; Toubekis, Argyris; Fernandes, Ricardo J.; Soares, SusanaThe current study aims to determine the effect of one-week tapering on the anaerobic potential of young swimmers based on a simple and non-invasive test. Twenty competitive young swimmers (12.83 ± 1.08 years) performed an all-out 25 m front crawl sprint coupled to an electromechanical speedometer before and after a week of taper. The variation of the velocity along time [v/(t) curves] was determined for each sw...
Beyond low back pain! The influence of physical activity on mental health, refl...
Parolini, Franciele; Becker, Klaus; Goethel, Márcio; Fernandes, Ricardo J.; Fonseca, Hélder; Ervilha, Ulysses F.; Vilas-Boas, João Paulo; Santos, RubimPsychological factors play a crucial role in the experience of acute low back pain and may influence functional outcomes. However, the interplay between these factors and levels of physical activity remains poorly understood. This cross-sectional observational study examined the relationship between psychological variables and functional disability in individuals with acute low back pain, considering different ...
Effectiveness of conservative interventions after acute hamstrings injuries in ...
Afonso, José; Olivares-Jabalera, Jesús; Fernandes, Ricardo J.; Clemente, Filipe Manuel; Rocha-Rodrigues, Sílvia; Claudino, João GustavoBackground: Hamstrings injuries are common in sports and the reinjury risk is high. Despite the extensive literature on hamstrings injuries, the efectiveness of the diferent conservative (i.e., non-surgical) interventions (i.e., modalities and doses) for the rehabilitation of athletes with acute hamstrings injuries is unclear. Objective: We aimed to compare the efects of diferent conservative interventions in t...
Breaking barriers: Artificial intelligence interpreting the interplay between m...
Parolini, Franciele; Goethel, Márcio; Becker, Klaus; Fernandes, Cristofthe; Fernandes, Ricardo J.; Ervilha, Ulysses F.; Santos, RubimLow back pain is one of the main causes of motor disabilities and psychological stress, with the painful process encompassing sensory and affective components. Noxious stimuli originate on the periphery; however, the stimuli are recombined in the brain and therefore processed differently due to the emotional environment. To better understand this process, our objective was to develop a mathematical representati...
Biomechanical Features of Backstroke to Breaststroke Transition Techniques in A...
Chainok, Phornpot; de Jesus, Karla; Mourão, Luis; Fonseca, Pedro Filipe Pereira; Zacca, Rodrigo; Fernandes, Ricardo J.; Vilas-Boas, João PauloThis study aimed to identify the biomechanical features of backstroke to breaststroke transition techniques (open, somersault, bucket, and crossover) in age-group swimmers. Eighteen preadolescent swimmers (12.2 ± 0.4 years old and 3–4 Tanner stages) underwent 4 weeks of systematic contextual interference training, comprising 16 sessions (40 min·session−1). Soon after, experimental testing was conducted where sw...

Vilas-Boas, João Paulo; Fonseca, Pedro; Sousa, Manoela Vieira; Sebastião, Ricardo; Carvalho, Diogo; Duarte, João Pedro; Zacca, RodrigoPorto Biomechanics Laboratory is a technological centre of the University of Porto dedicated to teaching, scientific and technological research, innovation, to provide specialized technical services and transference of knowledge and technology (product development) in Biomechanics (human and animal) of ergonomic, clinical, sports or biomimetic interest (e.g. design, computer animation and model development). LA...
Efeito da idade relativa promotor de diferenças antropométricas e motoras em jo...
Coelho, Eduardo Pereira; Noronha, Francisco; Canossa, Sofia; Fernandes, Ricardo J.Jogadores nascidos nos primeiros meses do ano civil tendem a apresentar maior maturação física e psicológica comparativamente com os jogadores nascidos nos últimos meses desse mesmo ano e têm maior probabilidade de serem selecionados pelos seus treinadores. Este fenómeno denomina-se efeito da idade relativa e as suas causas continuam por determinar1. O objetivo deste estudo foi explorar se jovens jogadores de p...
Upper limbs actions in successive front crawl swimming at sprint pace
Fernandes, Aléxia; Mezêncio, Bruno; Pereira, Gustavo; Silva, António; Marinho, Daniel A.; Soares, Susana; Vilas-Boas, João Paulo; Fernandes, Ricardo J.Propulsive swimming mechanics mainly depends on upper limbs' actions that perform three-dimensional movements in each cycle. Considering that hydrodynamic drag is proportional to the square of velocity, technical execution of segmental displacement at maximal exertions should be effective to ensure high and stable propulsive forces per cycle. Nevertheless, human movement is characterized by constraints that imp...
Avaliação da potência aeróbia e da velocidade máxima de nado jovens jogadores d...
Noronha, Francisco; Cardoso, Filipa; Rios, Manoel; Silva, Francisco; Fernandes, Ricardo J.; Canossa, SofiaO polo aquático é um desporto que solicita ambos os sistemas energéticos, razão pela qual o seu desenvolvimento e avaliação são fundamentais. Jogadores com melhor desempenho em testes de aptidão aeróbia conseguirão melhor resistir à fadiga específica do jogo, enquanto níveis elevados de velocidade serão decisivos para se propulsionarem e realizarem de forma veloz os movimentos acíclicos típicos do polo aquático...
