1. What is the Modified Bruce METs Equation?

The Modified Bruce protocol is a variation of the standard Bruce treadmill test used for cardiac stress testing. This equation estimates metabolic equivalents (METs) from the time achieved during the test.

2. How Does the Calculator Work?

The calculator uses the Modified Bruce METs equation:

Where:

• \( T \) — Time in minutes on the Modified Bruce protocol

Explanation: The equation provides a linear estimate of exercise capacity based on test duration.

3. Importance of METs Calculation

Details: METs estimation is important for assessing functional capacity, evaluating cardiovascular fitness, and determining appropriate exercise prescriptions.

4. Using the Calculator

Tips: Enter the total time achieved during the Modified Bruce protocol test in minutes. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the Modified Bruce protocol?
A: It's a graded exercise test that begins at a lower workload than the standard Bruce protocol, making it more suitable for elderly or less fit individuals.

Q2: What are typical METs values?
A: Healthy individuals typically achieve 10+ METs. Values below 5 METs indicate poor functional capacity.

Q3: How does this compare to standard Bruce?
A: The standard Bruce protocol typically produces higher METs values for the same duration due to its more aggressive workload increments.

Q4: What factors affect METs accuracy?
A: Patient effort, test administration, and individual biomechanics can all influence results.

Q5: Can this be used for exercise prescription?
A: Yes, the results can help guide appropriate exercise intensity for cardiac rehabilitation programs.
