What does the blood lactate threshold test measure?

Explanation:
The blood lactate threshold test measures the highest exercise intensity that can be sustained without lactate in the blood continually rising. At this point, lactate production and clearance are balanced, so you can hold a steady effort. Below this intensity, lactate stays at a manageable level; above it, lactate grows faster than it can be cleared, leading to fatigue and a dropping pace. This threshold reflects the shift from mainly aerobic to more anaerobic metabolism and helps athletes set training zones and gauge endurance performance.
