1. What Are Age-Adjusted Stress METs?

Age-adjusted stress METs provide a more accurate assessment of exercise capacity by accounting for the natural decline in physical performance that occurs with aging. METs (Metabolic Equivalents) measure the energy cost of physical activities.

2. How Does the Calculator Work?

The calculator uses an age-adjustment formula:

\[ \text{Age-Adjusted METs} = \text{Base METs} \times \text{Age Adjustment Factor} \]

Where:

Base METs — Measured metabolic equivalents during stress test
Age Adjustment Factor — Factor that accounts for age-related decline in physical capacity

Explanation: The adjustment factor typically decreases with increasing age to reflect the normal physiological changes that affect exercise capacity.

3. Importance of Age-Adjusted METs

Details: Age-adjusted METs provide a more realistic assessment of functional capacity, help in setting appropriate exercise prescriptions, and allow for better comparison across different age groups in clinical and research settings.

4. Using the Calculator

Tips: Enter the measured METs from your stress test and your current age in years. Both values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why adjust METs for age?
A: Age adjustment accounts for the natural decline in maximum exercise capacity that occurs with aging, providing a more accurate assessment of functional status.

Q2: What are normal MET values by age?
A: Normal values vary by age, with younger individuals typically achieving higher MET levels. Generally, 10+ METs is excellent for most adults, while values below 5 may indicate reduced functional capacity.

Q3: How often should stress testing be done?
A: The frequency depends on individual health status, but generally every 1-5 years for those with known cardiovascular risk factors or conditions.

Q4: Are there limitations to age-adjusted METs?
A: While helpful, these calculations don't account for individual variations in fitness, medical conditions, or medications that might affect exercise capacity.

Q5: Can I use this for exercise prescription?
A: Age-adjusted METs can help guide exercise intensity recommendations, but individual assessment by a healthcare professional is recommended for precise exercise prescription.
