Prior arm exercise speeds the VO2 kinetics during arm exercise above the heart level

Article Abstract:

The hypothesis that the initial O2 uptake kinetics during exercise where the rise in blood flow to the working muscles during an abrupt increase in exercise intensity is reduced would be faster when preceded by a bout of 6 min of high-intensity is tested. Results of the study demonstrate that prior high-intensity exercise caused a significant speeding of the VO2 fast component response during subsequent high-intensity arm crank exercise performed above, and not below, the level of the heart.

Muscle glycogen depletion alters oxygen uptake kinetics during heavy exercise

Article Abstract:

Hypothesis that muscle fiber recruitment patterns influence the oxygen uptake (VO2) after constant-load exercise was tested. Results suggest that muscle fiber recruitment influences both the VO2 primary and slow component amplitudes during high intensity exercise.
