How do you see the decision between electrical muscle stimulation and lifting weights?
Might be useful for rehab: http://ajs.sagepub.com/content/7/3/169.short I don't think it is useful for healthy people. You certainly won't gain any appreciable amount of muscle using it.
Why is that, anyway? I observed the same thing in my own rehab: the machine stopped doing anything useful long before I was able to e.g. stand on just my injured leg, but the exercises I was doing didn't feel any more intense than the machine in terms of muscle flexion. Do we know what the story is there?
Not sure, but I assume it's just that sending a shock through the muscle is just fundamentally different from contracting it through its full range of motion with your CNS.
Same question. I injured my ankle and although it's getting better I wanted to speed up progress so I bought this $33 electrical muscle stimulator.. I haven't had it long enough to know if its working, but I have grown to like the electrical shock/pulse it delivers.
