"Lactic Acid Causes Muscle Soreness"
Captions available
The idea
Lactate clears from muscle tissue well before delayed-onset soreness appears a day or two later — the timing does not match.
In practice
Delayed-onset soreness lingers long after exercise ends, well past when any fermented lactate remains.
Where people slip
Blaming next-day soreness on lactate is the error — lactate clears from muscle within about an hour, long before soreness begins.
