The primary purpose of the Bruce Protocol is to assess which of the following?

The Bruce Protocol is specifically designed to evaluate cardiovascular fitness, particularly through stress testing. It involves a treadmill exercise test that progressively increases the intensity of exercise, typically by increasing the speed and incline at regular intervals. This protocol allows for the assessment of an individual's aerobic capacity and overall cardiovascular endurance. It is widely used in clinical settings to assess heart function and diagnose potential cardiovascular issues. Unlike tests for bone density, muscle strength, or flexibility, which focus on different aspects of physical health, the Bruce Protocol directly measures the heart's response to exercise, making it a highly effective tool for assessing cardiovascular fitness.
