What You'll Find Here

The Science

What lactate threshold actually is, why it predicts race performance better than VO2max, and how it shifts with age in trained athletes.

Field Protocols

Stage-by-stage testing for running and cycling — warm-up through threshold, with measurement timing at each step.

Device Reviews

Finger-prick standards versus emerging non-invasive sensors, ranked on accuracy, field practicality, and cost per test.
