Description
Alessandro L. Colosio and co-authors measured how exercise intensity affects the repeatability of breathing gas measurements in a 2026 cycling study. Labs rely on oxygen uptake and related values, so knowing when those numbers wobble matters.
Forty-two healthy adults completed a ramp test plus six steady cycling trials spread over moderate, heavy, and severe intensity domains, each lasting six minutes. Two metabolic carts recorded oxygen uptake, carbon dioxide output, and ventilation. Values rose with intensity but did not drift between days. Variability shrank as work hardened, dropping below 5 percent for oxygen and carbon dioxide measures in the severe domain, and reliability coefficients were excellent. The domain-specific benchmarks help researchers judge real change against measurement noise.
