Is V̇O2peak a valid estimation of V̇O2max in swimmers with physical impairments?
Feitosa, Wellington G.; Barbosa, Tiago M.; Correia, Ricardo de Assis; Castro, Flávio A. de SouzaPeak and maximal oxygen uptake (V_O2peak and V_O2max, respectively) are used in assessing aerobic power. For swimmers with physical impairments, it is unclear whether the physiological variables obtained in 200-m and Nx200-m tests are similar. The objective of this study is to assess the validity of V_O2peak as an estimator of V_O2max and complementary physiological variables, in particular, carbon dioxide prod...
The 400-m Front Crawl Test: Energetic and 3D Kinematical Analyses
Correia, Ricardo de Assis; Feitosa, Wellington Gomes; Figueiredo, Pedro; Papoti, Marcelo; Castro, Flávio Antonio de SouzaThe aim of the study was to verify the relative contributions of energetic and kinematic parameters to the performance in 400-m front crawl test. Fourteen middle-distance swimmers participated in the study. Oxygen consumption was measured directly and blood samples were collected to assay lactate concentration. Both oxygen consumption and lactate concentration were used to calculate the: (i) overall energy expe...

Feitosa, Wellington G.; Correia, Ricardo de Assis; Barbosa, Tiago M.; Castro, Flávio A. de SouzaBiomechanical and coordination measurements are useful tools to assess swimming performance. Regarding Paralympic swimming, function and technique make these measurements complex. The aim of this study was to perform a systematic review of studies on biomechanics, coordination and performance in disabled swimmers following swimming protocols and in competitions. Data sources: PubMed, EMBASE, ISI Web of Knowledg...

Feitosa, Wellington G.; Correia, Ricardo de Assis; Barbosa, Tiago M.; Castro, Flávio A. de SouzaIn paralympic swimming, the biomechanical parameters related to performance are effectively determined according to the potentialities and peculiarities of each athlete. However, a clear integrated approach to these parameters for swimmers with physical disabilities at the speed of maximum oxygen uptake (vV̇O2max) is still practically non-existent.
Maximal oxygen uptake, total metabolic energy expenditure, and energy cost in s...
Feitosa, Wellington G.; Barbosa, Tiago M.; Correia, Ricardo de Assis; Castro, Flávio A. de SouzaThe purpose of this study was to assess the maximum oxygen uptake (V̇ O2max), the total metabolic energy expenditure (_Etot), and the energy cost (C) measured as the speed of V̇ O2max in swimmers with physical impairments. Eleven swimmers performed an Nx200- m front crawl test from a low to all-out speed and data were obtained at maximum aerobic power. The oxygen uptake was measured breath-by-breath by a teleme...

Feitosa, Wellington G.; Correia, Ricardo de Assis; Barbosa, Tiago M.; Castro, Flávio A. de SouzaDespite an increase in popularity of Paralympic sports, there is a lack of studies on these sports, and controversies regarding the classification system for Paralympian swimmers. The Paralympic classification system features 10 classes to provide fair competition for swimmers with a physical disability. The summary of the clean swimming speed (SS) can provide useful information for the classification system in...
