Expert Opinion

PROFESSOR PEDLAR ON BIOMARKERS

“Biomarkers are the Marmite of sports science.”

You either love them or hate them. There's rarely middle ground.

Professor Pedlar cuts through the polarised debate with refreshing clarity. The "hate camp" has valid concerns: invasive procedures, hefty price tags, and complexity.

Pedlar's most compelling insight? It's not just deficiencies we should monitor.

"We are now seeing athletes with excessively high biomarker values for some nutrients," Pedlar reveals.

"Using a blood test, you might be able to identify both deficiencies as well as excesses."

The actionable takeaway: Consider biomarkers not as universally necessary or wasteful, but as context-dependent tools.

Important ⚠️ Ensure you don't step outside your scope of practice and are properly insured for any advice provided.
