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...

Strength Training versus Stretching for Improving Range of Motion: A Systematic...
Afonso, José; Ramirez-Campillo, Rodrigo; Moscão, João; Rocha, Tiago; Zacca, Rodrigo; Martins, Alexandre; Milheiro, André A; Ferreira, João(1) Background: Stretching is known to improve range of motion (ROM), and evidence has suggested that strength training (ST) is effective too. However, it is unclear whether its efficacy is comparable to stretching. The goal was to systematically review and meta-analyze randomized controlled trials (RCTs) assessing the effects of ST and stretching on ROM (INPLASY 10.37766/inplasy2020.9.0098). (2) Methods: Cochr...
VO2FITTING: A Free and Open-Source Software for Modelling Oxygen Uptake Kinetic...
Zacca, Rodrigo; Azevedo, Rui; Figueiredo, Pedro; Vilas-Boas, João; Castro, Flávio; Pyne, David; Fernandes, RicardoThe assessment of oxygen uptake (VO₂) kinetics is a valuable non-invasive way to evaluate cardiorespiratory and metabolic response to exercise. The aim of the study was to develop, describe and evaluate an online VO₂ fitting tool (VO₂FITTING) for dynamically editing, processing, filtering and modelling VO₂ responses to exercise. VO₂FITTING was developed in Shiny, a web application framework for R language. Vali...
In-Water and On-Land Swimmers’ Symmetry and Force Production
Carvalho, Diogo Duarte; Soares, Susana; Zacca, Rodrigo; Marinho, Daniel; Silva, António; Pyne, David; Vilas Boas, J. Paulo; Fernandes, Ricardo J.Although performance and biomechanical evaluations are becoming more swimming-specific, dryland testing permits monitoring of a larger number of performance-related variables. However, as the degree of comparability of measurements conducted in-water and on land conditions is unclear, we aimed to assess the differences between force production in these two different conditions. Twelve elite swimmers performed a...
Velocidade crítica obtida por um modelo de quatro parâmetros e sua relação com ...
Zacca, RodrigoModelos bioenergéticos de dois, três e quatro parâmetros podem ser usados para prescrever a velocidade crítica (VC) sendo que o último modelo melhor descreve a relação entre velocidade (v) e tempo de exaustão (tlim) em nadadores. O objetivo do presente estudo foi verificar as respostas metabólicas ao se nadar em intensidade equivalente à VC4par até exaustão e verificar a validade de predizê-la somente por meio ...
