Finally, here are some more open-ended questions to spark some debate on this interesting topic:[list]
[*]Previous literature has indicated that the one form of strength (for example eccentric) is not a reliable predictor or indicator of other forms of strength (for example concentric). If we do assume that EMS can develop strength in athletes, is there any reason to think that the strength gains would be anything more than gains in isometric strength?
[*]Can strength developed in such a non-functional manner (no movement, isolated muscles, etc.) have any impact on performance in the real world?
[*]Even if the exact same protocol is used for every muscle group, is it likely that the strength gains will be uniform across all muscle groups?
[*]Is it possible that development of particular muscle groups (only superficial muscles can be stimulated) without the concurrent development of other muscles in that same limb may result in strength imbalances (not left:right; but one muscle to another) that could negatively affect performance?
Those are some well thought of, world class questions.
To be honest, I have not gone beyond using EMS for recovery and rehab, because of the issues you have addressed.
With all due respect to Charlie, his greatest athlete (Ben) has achieved world class times with the assistance of AS, while using heavy weights and some plyo/drills -including sprinting. For me, those things had more of effect on his power. Take away the EMS, and I still think Ben would have run just as fast.
Don't believe me, lets look at Maurice Greene 9.79, Tim Montgomery 9.78. As far as I know they use, weights plyo/drills and sprinting, MINUS EMS for power development.
Does EMS work for power development? Maybe -although I doubt it. Personally, I would rather spend my energy and time using the more PROVEN methods of power development.
