It seems as though the simple answer would be yes, but I mean recovery specifically related to work capacity and your CNS. At my gym when we MMA spar (with 16's) we go pretty light making sure to mix things up, but most people don't wear headgear because it gets in the way of clinching, wrestling, and ground fighting. I am looking to do more training sessions (currently at 3 hours a day, 4-5 days a week) and the only thing in my way is my work capacity. I have recently bought and started using L-carnitine, beta alanine, creatine, melatonin, ZMA as well as doing light GPP in the morning, and trying to get more massages and do more stretching. Would wearing head gear help my work capacity?
