You'll have to elaborate.
Thumbing out a speculation:
A hammer/impact drill can drive through material more efficiently than a standard drill.
When that model is translated to the human body, can there be an opposing action that trains the quickness of the driver via the impact force?
Punching bag work, for example.
I know, fast-twitch is largely genetic....

...I don't think you know how a hammer drill works.
When Mrs Doug90000 gets home I'll ask her to provide comment.
Maybe not. But I am nonetheless able to use them (drilled for tapcons today).
I gather the hammer drill provides high-rate longitudinal forces, versus high-rate torques of impact drills.
If so, I think hammer drill was an apt analogy to begin with, though 'impact' should've been left out.
Still, I am not ready to elaborate.
Correct as needed.
What happens at Doug9000, stays at Doug9000.
No elaboration yet, but here is the inspiration. Just put this up today. Actors (hammer drill and human) notably absent.
Pretty sure you're talking about power training, pretty sure power cleans are a good bet to train that.
Hammer drills work because they use hard material (tungsten carbide) to hammer and break brittle material like concrete and brick.
A regular drill uses a hard, sharp material (usually HSS) to cut or carve material away, forming a more or less continuous curl or chip when fed properly.
Twist drills don't work at all well on concrete, and hammer drills don't work at all well in wood or steel.
No relation, simile or metaphor that I can see regarding strength training.
