1. What is the WMA Age Calculator?

The WMA (World Masters Athletics) Age Calculator determines age-grading percentages for track and field performances. It allows athletes of different ages to compare performances by adjusting for age-related decline.

2. How Does the Calculator Work?

The calculator uses the WMA age-grading formula:

Where:

• \( Age\ Standard \) — The standard time for a specific age group (minutes)
• \( Time \) — The athlete's actual performance time (minutes)

Explanation: The equation compares an athlete's performance to the world record standard for their age group, expressing it as a percentage where 100% represents world record level.

3. Importance of Age-Grading

Details: Age-grading allows fair comparison between athletes of different ages, helps track performance changes over time, and provides motivation by showing how current performances compare to age-group standards.

4. Using the Calculator

Tips: Enter the age standard time and your actual performance time, both in minutes. All values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: Where can I find age standard times?
A: Official WMA age standards are published on the World Masters Athletics website for each event and age group.

Q2: What is a good age-grading percentage?
A: 90%+ is world-class, 80-89% is national class, 70-79% is regional class, and 60-69% is local class.

Q3: Does this work for all track events?
A: Yes, but you need the correct age standard for each specific event (100m, 1500m, etc.).

Q4: How often are age standards updated?
A: WMA typically updates standards every 5 years to reflect current world records.

Q5: Can I use this for road races?
A: Road races use slightly different age-grading tables, though the principle is similar.
