That is very interesting. It sounds sort of like the reasoning behind injury prevention and rehabilitation regimens like "The 7 Minute Rotator Cuff Solution", which in simple terms is that the key to musculoskeletal health is getting and keeping the small muscles engaged, and not letting a few big muscles do all the work all the time. The small muscles of the rotator cuff are essential to stabilizing the shoulder and preventing injury, but they become both weaker and slower if they're not engaged on a regular basis -- which leads to vulnerability in the shoulder joint.
Slightly off-topic, but this is also the argument for the use of free weights, rather than weight machines, in strength training. While the "prime movers" do most of the work, free weights engage the smaller muscles in the equally important job of balancing and stabilizing the load.
