Contributos da biomecânica para o estudo do rendimento desportivo em natação
Vilas-Boas, João Paulo; Oliveira, Sara; Silva, Diana; Sousa, Ana Francisca; Ribeiro, João; Jesus, Kelly de; Costa, Lígia; Figueiredo, PedroNa actualidade, o progresso do rendimento desportivo ao mais alto nível só é susceptível de ser conseguido através de uma combinação (que diríamos necessariamente feliz) de um vasto conjunto de factores: é necessário desde logo um pouco de sorte (como em tudo na vida – mesmo que seja para cozinhar a sopa de pedra requerida), mas sobretudo um praticante talentoso e motivado, condições de treino adequadas, um env...
Novas aplicações de tecnologia computacional e biomecânica ao desenvolvimento d...
Vilas-Boas, João Paulo; Costa, Lígia; Santos, S.; Pereira, Francisco; Oliveira, N.; Rebocho, M.; Monteiro, L.; Oliveira, Sara; Jesus, Kelly deA Biomecânica constitui um dos domínios das Ciências do Desporto onde o desenvolvimento tecnológico se tem revelado mais exuberante, nomeada e especialmente a par dos desenvolvimentos operados na computação e nas novas tecnologias em geral. A natação, por seu lado, constitui a referência maior de entre as modalidades desportivas praticadas na água e, de entre estas, aquela onde, aparentemente, a investigação ci...
Validation of a cable speedometer for butterfly evaluation
Morouço, Pedro; Lima, António B.; Semblano, P.; Fernandes, Daniel; Gonçalves, Pedro; Sousa, Filipa; Fernandes, Ricardo J.; Barbosa, Tiago M.Getting fast results from the evaluation of swimmers is one of the most important goals to achieve with technological development in the field. The purpose of this study was to validate a real-time velocimetric device (speedometer) through the comparison of their results with computer assisted videogrametry. The sample included 7 international level swimmers (3 females and 4 males). Each swimmer performed four ...
A kinematical, imagiological and acoustical biofeedback system for the technica...
Lima, António B.; Semblano, P.; Fernandes, Daniel; Gonçalves, Pedro; Morouço, Pedro; Sousa, Filipa; Fernandes, Ricardo J.; Barbosa, Tiago M.A system for real time velocimetric feedback, and for immediate disposal of kinematica data, and model, synchronized with dual-media video images, will be presented.
Energy cost and intra-cyclic variation of the velocity of the centre of mass in...
Novais, Daniel; Carmo, Carla; Gonçalves, Pedro; Sousa, Filipa; Lima, António B.; Barbosa, Tiago M.; Santos, Paulo; Machado, Leandro; Keskinen, Kari L.The purpose of the present study was to analyse the relationship between energy cost (C) and intra-cyclic speed fluctuations (dv) in breaststroke.
Validation of a cable speedometer for butterfly stroke
Morouço, Pedro; Lima, António B.; Semblano, P.; Fernandes, Daniel; Gonçalves, Pedro; Sousa, Filipa; Fernandes, Ricardo J.; Barbosa, Tiago M.Most of the approaches available for technical evaluation of swimmers are very expensive and time consuming. Thus, one of the most important goals to achieve in swimming research should be to get fast and interactive results from the evaluation process. The purpose of this research was to compare me real-time velocimetric results obtained from a cable velocimeter with those extracted from computerised videogram...
Time limit at the minimum velocity of VO2max and intracyclic variation of the v...
Balonas, Ana; Gonçalves, Pedro; Silva, José; Marinho, D.A.; Moreira, Pedro; Lima, António B.; Barbosa, Tiago M.; Keskinen, Kari L.The purpose of this study was to analyse the relationship between time limit at the minimum velocity that elicits maximal oxygen consumption (TLim-vVO2max) and intra-cyclic variations of the velocity of the centre of mass (dv) in the four competitive swimming techniques. Twelve elite male swimmers SWIMMING BIOENERGETICS Rev Port Cien Desp 190 6(Supl.2) 185–197 swam their own best technique until exhaustion at t...
Relationship between energy cost, swimming velocity, speed fluctuation in compe...
Barbosa, Tiago M.; Lima, António B.; Portela, Ana; Novais, Daniel; Machado, Leandro; Colaço, Paulo; Gonçalves, Pedro; Fernandes, Ricardo J.The purpose of this study was to analyse the relationships between the total energy expenditure ( tot), the energy cost (EC), the intra-cycle variation of the horizontal velocity of displacement of centre of mass (dv) and the mean swimming velocity (v) in the four competitive swimming strokes.
Relationships between energy cost, swimming velocity and speed fluctuation in e...
Barbosa, Tiago M.; Lima, António B.; Colaço, Paulo; Gonçalves, Pedro; Machado, Leandro; Fernandes, Ricardo J.; Keskinen, Kari L.; Vilas-Boas, João PauloThe purpose of this study was to analyse the relationships between the total energy expenditure (tot), the energy cost (EC), the intra-cycle variation of the horizontal velocity of displacement of centre of mass (dv) and the mean swimming velocity (v) in elite butterfliers.
