Phase 2 pulmonary oxygen uptake kinetics (ϕ2 τV̇o2P) reflect muscle oxygen
consumption dynamics and are sensitive to changes in state of training or health. This study …

Purpose We hypothesised that during a rest-to-exercise transient in hypoxia (H), compared
to normoxia (N),(i) the initial baroreflex sensitivity (BRS) decrease would be slower and (ii) …

Purpose Continuous incremental protocols (CP) may misestimate the maximum aerobic
velocity (V max) due to increases in running speed faster than cardiorespiratory/metabolic …

Purpose We tested the vagal withdrawal concept for heart rate (HR) and cardiac output (CO)
kinetics upon moderate exercise onset, by analysing the effects of vagal blockade on …

We hypothesised that vagal withdrawal and increased venous return interact in determining
the rapid cardiac output (CO) response (phase I) at exercise onset. We used lower body …

Purpose. Cardiac output (CO) is a cornerstone parameter in precapillary pulmonary
hypertension (PH). The Modelflow (MF) method offers a reliable noninvasive determination …

Gas exchange data acquired repeatedly under the same exercise conditions are assembled
together to improve the kinetic parameters of breath-by-breath oxygen uptake. The latter are …

6-min walk tests (6MWT) are routinely performed in patients with chronic obstructive
pulmonary disease (COPD). Oxygen uptake (V˙ O 2) kinetics during 6MWT can be modeled …

This chapter deals with the alternate view of exercise transients that stemmed from the
School of Los Angeles, set by Karlman Wasserman and Brian Whipp. The pathway that led …

The O2 uptake (V̇o2) data at the onset of an exercise are usually fitted with a mono-
exponential function, after removal of the data pertaining to a conventional initial time period …
