Specific physiological factors, such as cardiorespiratory fitness levels and oxygen uptake kinetics, determine how rapidly an individual becomes short of breath during physical exertion.

The analysis

The retrieved literature consistently supports the claim that physiological parameters like oxygen uptake kinetics (VO2 kinetics), cardiorespiratory fitness levels, and muscle composition directly influence exercise tolerance and the speed at which individuals experience shortness of breath.

The Influence of Age and Cardiorespiratory Fitness on Kinetics of Oxygen Uptake

Recorded source metadata

Philip D. Chilibeck, Donald H. Paterson, Robert J. Petrella, David A. Cunningham. The Influence of Age and Cardiorespiratory Fitness on Kinetics of Oxygen Uptake. 1996. https://doi.org/10.1139/h96-015

Paper [0] demonstrates that relative cardiorespiratory fitness is a strong predictor of oxygen uptake kinetics (VO2 kinetics), directly linking fitness levels to the physiological efficiency underlying breathlessness during exercise.
