After you've increased your lactic power then it's time to build on that with lactic capacity which is the ability to repeat your lactic power.
Going back to the example of the half back line stoppage clearance used in the lactic power description, this would be the ability to replicate that type of speed over the course of en entire game.
The LACTIC CAPACITY training manual is a 3 week program that progressively increases lactate each session to teach your body rain with and through it. You DO NOT need this type of work until your 4 - 6 weeks out from your first full contact game.
By the end of the 3 weeks you should be able to buffer lactate faster resulting in your performing the progressive number of intervals at a level close to your testing result and your heart rate should decrease faster after each set.
