The Slow Component Of The Vo2 Response Is Explained By The Increase In Glycolytic Contribution, Austin Shaw, Ethan J. Hein, Jacob L. Mcnary, Brady C. Mclain, David W. Hill, Madison B. Landtiser, Lydia K. Caldwell, Sarah E. Deemer
International Journal of Exercise Science: Conference Proceedings
During severe intensity exercise, energy contribution from glycolysis leads to accumulation of intracellular H+ in the working muscles. This acidification results in decreased efficiency in the excitation-contraction coupling mechanism in the muscle cells, which decreases force production. Some studies have suggested that additional, progressive recruitment of glycolytic (type II) muscle fibers may be needed to maintain force production in constant power exercise which causes an increase in oxygen uptake over time (the VO2 slow component) after ~3 minutes. PURPOSE: The purpose of this study was to determine if the amplitude of the VO2 slow component is related …
