Which of the following is considered a normal result for an Exercise Tolerance Test (ETT)?

A normal result for an Exercise Tolerance Test (ETT) is considered to involve the ability to achieve a workload of more than 6 METs (Metabolic Equivalents). This level of performance indicates an adequate cardiovascular response and overall fitness, suggesting that the individual can engage in moderate physical activities without undue fatigue or risk. In general, 6 METs is a benchmark used in assessments to evaluate an individual’s functional capacity and cardiovascular health, particularly in the context of identifying potential risks in driving or performing tasks that require a certain level of physical endurance.

Reaching beyond this level typically signifies good aerobic capabilities and is often associated with a lower risk of cardiovascular events during physical exertion. Lower MET levels would be seen as indicative of compromised physical fitness, which may warrant closer monitoring or further evaluation in clinical settings.
