"Recovery" can refer to several different things.

1) "Recovery" can refer to the structural repair process of fixing the microtrauma. The damaged proteins can takes several days to be repaired and all evidence of damage removed. Even at the end of seven days after significant muscle damage from eccentric muscle actions, you may still see some small fibers regenerating.

2) Strength - this can be acute recovery as in the necessary time to rest between sets. Or it can mean the days that it usually takes to regain baseline strength after muscle damaging exercise.

So the trick is to have the CNS "recover" just in time to hit the muscle again as the acute anabolic effects are wearing off. That way you can stay anabolic more of the time. Training once every 7 days will still allow you to grow, it just takes longer for the gains to accumulate. Training more frequently is more efficient if your goal is just to get bigger.
