Nearly all of the research in this search says there is either no statistical difference in effectiveness or “The diminished force output suggests that the overload stresses required for strength training necessitate the inclusion of resistance training on stable surfaces.”
Very nice thread Chris.
I don’t know of any research that substantiates that peripheral strength gains can be improved by training on an unstable surface.
It would seem that force production would be compromised on an unstable surface. One of the first things that we do if we are carrying something and feel as if we are going to fall is to drop the object (unless it is a baby).
Thanks for the research.
