Training twice a day?

[MuscleScience]

There was several papers I read on this years ago. Basically training the same body part twice a day is of little benefit. You are creating micro trauma to the myofibril when you exercise. If you hit the same body part twice, you effectively hinder recovery from the first bout of exercise and hit the muscle at a vulnerable period in the acute phase of growth and repair process.

I think there is no problem hitting say legs in to morning and back at night though.

I know you've made comments on this subject on other threads MS, glad you're here.

As you probably know I have a medical background and I also teach Anatomy & Physiology, so we both have a similar base of knowledge.

Would love to see the papers, but I'm just hard pressed understanding what has to recover. As I mentioned to Mr. BB, the ATP is going to be recovered in minutes. Electrolytes (sodium & potassium in particular) I can understand, but they must be be lost through profuse sweating or diet imbalances - so that is pretty much a non-issue to me for guys in the gym.

How do you guys explain Olympic athletes training throughout the day, similar with professional athletes, etc. There is definitely repetition to similar muscle groups occurring multiple times per day and on a daily basis.. I would challenge you and say that the CNS and PNS is working one hell of a lot harder if you are an Olympic swimmer or gymnast who is using practically every muscle in their body compared to a bodybuilder who is only hitting their deltoids.

As a physical therapist working is sports medicine, training someone to come back from a knee injury - trust me, exercises are done repetitively throughout the day and they recover just fine.

But hey, with all of that just said - if there is documentation out there (and as you must know MS, there must be more than a few that substantiates the same thing, because research findings are all over the place for just about everything) - then I'll step back from my position. I personally have only found radom loose references out there with nothing to back it up.

Peace to you all - I am NOT trying to be an A-hole - just digging the conversation with my fellow members.
