Is a progressive recruitment of muscle fibers required for the development of the slow component of V̇o2 kinetics?

Abstract

to the editor: Zoladz et al. ([6][1]) present a reanalysis of data taken from their previous study ([3][2]) and they evaluated the oxygen uptake (Vo2) response in isolated dog gastrocnemius in situ during 4-min of contractions at ∼60–70% of peak Vo2. In their preparation, all muscle fibers
