[Relationship between oxygen deficit and VO2max in supramaximal running]
1Laboratoire de Physiologie humaine appliquée, ISEP, Université de Liège, Sart Tilman, Belgique.
Abstract:
The maximal accumulated oxygen deficit (DO2max, ml O2/kg) has been measured in 43 healthy male subjects with different VO2max (45-70 ml O2/kg.min) during the course of supramaximal runs performed until volitional exhaustion on an inclined treadmill. It was found that DO2max and VO2max were linearly related: DG2max = 39.7 + 0.31 VO2max (r = 0.701; P less than 0.001). Mean accumulated DO2max (58 ml O2/kg) corresponds to an amount of energy equal to 1212 J/kg.

Respiration and Gaseous Exchange
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves the...
Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.
The Functional Residual Capacity (FRC) represents the air in the...

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
