Creatine Phosphate

Hi! I was just wondering why CP fuels replenish during passive recovery rather than active recovery?

First of all this is a question you would ever be asked.

Second of all im not entirely sure but this is my reasoning. If you decided to do an active recovery even at a very low intensity there is still a chance that pc stores are going to be still in use rather than being replenished. Whereas if you were completely inactive the body uses fats during inactive thus allowing a chance for the pc to restore itself.

CrPO4 is one of the first things to get replenished in recovery, it has a half life of only 60-90sec, so a minutes rest and you can do another bout of high intensity, anaerobic training. it requires very little to get replenished - oxygen, creatine, and phosphates. so thats why it doesnt need any form of active recovery, as opposed to something like lactate or H+ ions, which need aerobic respiration to be brought back to baseline

PCr is strictly used in anaerobic conditions, so a very low intensity recovery wont affect PCr (its only used for high intensities, when you exceed 100% of VO2 max)
