 Maximal oxygen uptake, total metabolic energy expenditure, and energy cost in swimmers with physical disabilitiesWellington G. Feitosa, Tiago M. Barbosa, Ricardo De A. Correia and Flávio A. De S Castro International Journal of Performance Analysis in Sport, 2019, vol. 19, issue 4, 503-516 Abstract: The purpose of this study was to assess the maximum oxygen uptake (V̇O2max), the total metabolic energy expenditure ($$\dot Etot$$E˙tot), and the energy cost (C) measured as the speed of V̇O2max 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 telemetric gas exchange system. The $$\dot Etot$$E˙tot was calculated from the aerobic and anaerobic pathways at maximal intensity. The C was obtained by the ratio of the $$\dot Etot$$E˙tot and the mean swimming speed. The V̇O2max was 38.2 ± 8.3 mL.kg.min−1, the $$\dot Etot$$E˙tot was 191.9 ± 51.7 kJ, and the C was 0.8 ± 0.2 kJ.m−1. The energy contribution of the aerobic pathway was higher (p 0.05). There was no gender effect on the results of the energy contributions (p > 0.05). The anaerobic lactic pathway contribution was higher in male than in female swimmers (p Date: 2019 Downloads: (external link) Related works: Export reference: BibTeX RIS (EndNote, ProCite, RefMan) HTML/Text Persistent link: https://EconPapers.repec.org/RePEc:taf:rpanxx:v:19:y:2019:i:4:p:503-516 Ordering information: This journal article can be ordered from DOI: 10.1080/24748668.2019.1631053 Access Statistics for this article International Journal of Performance Analysis in Sport is currently edited by Peter O'Donoghue More articles in International Journal of Performance Analysis in Sport from Taylor & Francis Journals |
