For an exercise stress test (ETT), what minimum MET level is required to pass?

To determine the appropriate minimum MET level required to pass an exercise stress test (ETT), it is essential to understand what METs (Metabolic Equivalent of Task) signify. One MET represents the resting energy expenditure of the body, and higher MET levels indicate greater physical exertion.

A minimum of 6 METs is generally considered necessary during the ETT to demonstrate sufficient exercise capability for commercial drivers. This level is significant as it reflects a driver's ability to engage in activities that require a moderate level of physical effort, which is essential for ensuring safety while operating a vehicle. Meeting or exceeding the 6 MET threshold indicates that the individual has adequate cardiovascular fitness and can handle the demands of driving.

Maintaining physical fitness is crucial for drivers, as their job often involves long hours of sitting and can impact cardiovascular health. Thus, the 6 MET requirement during the ETT is not just about passing the test; it ensures that drivers are fit enough to perform their duties without undue risk to themselves or others on the road.
