Because someone was asking for advice which directly relates to it and you had not, as yet, even mentioned the subject. go figure.
The more weight you use, the more power you can generate. That's why a huge guy like Shane Hamman who is well over 300 pounds can jump this high. Plyometrics are useful, but they are just one tool in the toolbox. They aren't the whole package. [ame="http://www.youtube.com/watch?v=UoCZne0g-e8"]YouTube - Shane Hamman box jump[/ame]
This is still a plyometric exercise. doing fast squats with an explosive push is still a plyometric exercise. for a fighter, the largest portion of thir strength training should be plyometric.
The stronger a muscle is, the more explosiveness it can have. The two are not mutually exclusive. The reason for that video was the fact that Shane Hamman typically does not do plyometrics. He trains the Olympic lifts almost exclusively now. And at 360 pounds, the guy sure can jump.
