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.”
Thanks, Natalie. Yes, that would be absurd.
But, regarding balance, don’t we also know that there is no one balance skill or motor pathway. Each movement is specific unto itself with each change including any resistance differences involved creates a new motor pathway. There’s no way to train for a general “balance” skill or sense. For example,
“Skillful and efficient performance in a particular technique can be developed only by practice of that technique. Only in this way can the necessary adjustments in the neuromuscular mechanism be made to ensure a well-coordinated movement (p. 507).” “Strength or endurance training activities must be specific to the demands of the particular activity for which strength or endurance is being developed. The full range of joint action, the speed, and the resistance demands of the movement pattern should be duplicated in the training activity (p. 465).”

“A common misconception is that fundamental abilities can be trained through various drills and other activities…For example, athletes are often given various ‘quickening’ exercises, with the hope that these exercises would train some fundamental ability to be quick, allowing quicker response in their particular sport. There are two correct ways to think of these principles.
First, there is no general ability to be quick, to balance, or to use vision…Second, even if there were such general abilities, they are, by definition, genetic and not subject to modification through practice…A learner may acquire additional skill at a drill…but this learning does not transfer to the main skill of interest” (Schmidt, 1991, p. 222).”

Some of those quote got off the balance argument, but they refer to the general vs. specific nature (or lack thereof) of training.
