I'm a believer in muscle memory. I saw a discussion on this subject on another board and i read alot of guys saying noway, you loose your muscle tissue and you have to work out to regain them to get your size back. I havta disagree with that. First you have your skeletal muscle then you have fascicles which are bundles of muscle fibers and in the fibers you have myofibrils. So when you stop working out you dont loose muscle fibers, thats a falicy. Yes you will loose mitochondria within muscle cells and the individual muscle fibers will decrease in size due to the progressive loss of myofibrils, but the fibers will not be lost. This is called disuse atrophy. Yes you can loose muscle fibers, but this is like if you are bed ridden for 6months to 2 years then you pretty much shut down nerve impulses to the muscle tissue and eventually you loose the nerves. that is called denervation atrophy, that is when muscle fibers will be replaced by connective tissue. Thats when you loose muscle. Anyways i'm rambling, your muscle fibers will shrink but not dissapear, when you resume working out you will gain more myofibrils which will fill in the muscle fiber again and make it larger. So i am a firm believer in muscle memory...rot
