for sheer power, rather than strength being measured in sports suited to certain levers, I would rank strongman the highest, along with heavier weight lifters and shot putters who must be both exceptionally strong and powerful.
Some of the strongman and shot putters though, near or over 2m tall, may be less suited in weightlifting/powertlifting, but would have few peers with regard to expressing absolute power.
In terms of sport, the ability to apply power (assuming high levels of skill) is what it is all about. That is why the NFL, and most other major sports, emphasise power tests rather than strength feats, albeit that smart weight training is critical to their development.
Of course, some of the heavier Olympic lifters would have incredible leg power.
Having said, I do enjoy the shorties lifting weights above their heads. Thankfully, there are many strength sports for people of all sizes.
