I have been exercising regularly for about 2 years and completed my first half Ironman earlier this year. I am currently recovering from ACL injury (from recreational basketball game). It has been about 3 weeks since surgery and I can put some weight on it again. I am told that rehab will be about 3-4 months.
Maybe I can start swimming again relatively soon but expect it will be at least a few months before I can do most of what I was accustomed to.
I know my VO2 max will fall (it probably already has to some degree) but how large of a decrease in VO2 max is expected during recovery?
