Question

A subject performs a symptom-limited maximal exercise test on a cycle ergometer; the ventilatory threshold is estimated at 37% of the subject's O2max. These findings are consistent with which of the following?

a) Anaerobic threshold
b) Respiratory compensation point
c) Metabolic acidosis
d) Ventilatory reserve

Answer 1

The ventilatory threshold estimated during a maximal exercise test is consistent with the Respiratory compensation point.

Step-by-step explanation:

The findings of the ventilatory threshold estimated at 37% of the subject's O2max in a symptom-limited maximal exercise test on a cycle ergometer are consistent with option b) Respiratory compensation point.

The ventilatory threshold is the point during exercise where the body switches from primarily using aerobic metabolism to relying more on anaerobic metabolism. At this threshold, there is an increase in respiratory rate and depth to compensate for the increased need of oxygen and removal of carbon dioxide.

This respiratory compensation point is often used to determine exercise intensity and training zones for athletes.
