What Is a Lactate Threshold?

There are 27 or 28 different definitions for lactate threshold in the scientific literature because there isn't really a strong pressure or ecological incentive to standardize things. There is also a glucose threshold so up to that same intensity your plasma glucose levels are relatively constant but over that intensity they tend to rise. The whole notion of fat max just goes right out the window well unless you're a coach and you want to charge people seventy five dollars a test to determine their fat max.
