BMI for Athletes: Is It a Reliable Measure?

BMI is often used to assess health, but it can be misleading for athletes and highly active individuals.

Why BMI May Not Work for Athletes

• BMI does not distinguish between muscle and fat
• Athletes often have higher muscle mass
• May be classified as overweight or obese despite low body fat

Example

• Professional rugby player: BMI = 28 (overweight)
• Body fat: 10% (very healthy)
• Reality: Excellent health and fitness

Better Alternatives

• Body fat percentage measurement
• Waist-to-hip ratio
• Performance and fitness tests
• DEXA scan or bioelectrical impedance

When to Use BMI

• For general population screening
• Not for individual athletic assessment

Conclusion

BMI is not a reliable measure for athletes. Use more specific tools to assess health and fitness in athletic populations.
