I can't wait for Kane to respond...I just can't do it!
Um...yes, muscle glycogen is depleted. That doesn't automatically mean that muscle is going to be wasted. If pre workout nutrition is good, then catabolism can be kept to a minimum. It's easy to replenish muscle glycogen and can be done in a matter of hours. Resistance training depletes muscle glycogen also. But I still train more than twice a week. Don't you?
Have you ever seen a sprinter? I imagine that some of them do sprints more than once a week. If your muscle glycogen becomes completely depleted, it's not the end of the world; it's time to eat.
I know you're trying to help, but the advice wasn't good and the response to Kane's question was worse. It was altogether not true. Interestingly, you didn't even answer his questions. You talked about glycogen and he was talking about strength. They're not the same thing.
In the second post telling him to read the HIIT article...I'm sure he already has. He probably read it a couple of years ago. You have to consider the audience that the article was written for.
