Hi-
So when we collect lactate samples it's actually a NET lactate value (net lactate= lactate production - lactate clearing). On the human net lactate spectrum we can measure NET lactate values between 0.6 and 32 mmol. Each NET lactate value has various characteristics in terms of how can effect performance. Some of those different characteristics relevant to performance include: trainability, power, capacity, and velocity. Each net lactate energy system varies in these characteristics and be trained accordingly.
V4- simply means velocity at 4 mmol. It's pretty much an arbitrary data point which really has no value for performance in any event.
