Implication

Cardiac output may govern phase I VO2 at exercise onset; leaves open translation to clinical populations or interventions.

Structured PICO

Population

6 men, age 24.2 +/- 3.2 years, maximal aerobic power 333 +/- 61 W

Intervention

Constant load exercises at 50 and 100 W

Outcome

Kinetics of systemic O2 delivery (QaO2), lung O2 uptake (Vo2), and cardiac output (Q) at exercise onsetsurrogate

In unsteady states at exercise onset, lung VO2 is dissociated from muscle O2 consumption, with cardiac output kinetics being twofold faster than VO2 kinetics.
