1. What is the 1.5 Mile Run Test?

The 1.5 mile run test is a field test used to estimate aerobic capacity (VO₂max). It measures how quickly you can complete 1.5 miles (2.4 km) of running, which correlates with cardiovascular fitness.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( time_{min} \) — Time to complete 1.5 miles in minutes
• \( VO_2 \) — Estimated maximal oxygen consumption in mL/kg/min

Explanation: The equation converts your running performance time into an estimate of your maximal oxygen uptake, a key measure of cardiovascular fitness.

3. Importance of VO₂max Calculation

Details: VO₂max is considered the gold standard measure of cardiovascular fitness. Higher values indicate better aerobic endurance and cardiovascular health.

4. Using the Calculator

Tips: Enter your 1.5 mile run time in minutes (e.g., 12.5 for 12 minutes 30 seconds). The time must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this test?
A: While not as precise as lab tests, it provides a reasonable estimate (±10-15%) of VO₂max for most healthy individuals.

Q2: What are typical VO₂max values?
A: Average values range from 30-45 mL/kg/min for most adults, with athletes often exceeding 50 mL/kg/min.

Q3: How should I perform the test?
A: Run 1.5 miles as fast as possible on a track or measured course, recording your exact time in minutes and seconds.

Q4: Are there limitations to this test?
A: Results may be less accurate for very fit or very unfit individuals, and running efficiency can affect results.

Q5: How can I improve my VO₂max?
A: Regular aerobic exercise, especially high-intensity interval training, can significantly improve VO₂max over time.
