Susan,
Exposure to high lactate levels results in other accommodations than simple
tolerance and buffering. Increased oxidative capacity (citrate synthase) and
uptake is one such "learning" process. Increased mitochondrial density
another. Both add to the capacity to use lactic acid as an immediate fuel
source.
