Lactate handling
The Textbook Account is Outdated. Lactate is not the cause of muscle soreness and is not merely an anaerobic waste product — it is a preferred fuel for heart and brain and a signaling molecule with its own receptor.
In depth
Produced continuously, not only under oxygen debt, and shuttled between tissues as fuel and signal.
What drives it
Training load increases it.
Produced continuously, not only under oxygen debt. Carried by the intermediary-metabolism, micronutrient and clinical reviews. doi 10.3390/nu18132141 · PMC9967593
Sugar burning increases it.
