When we read how some athlete was clocked at some MPH, that isn't how this works.
It takes all sprinters a good 50m to reach their topend that max velocity, so unless an athlete is clocked after 50mish, forget it.
At around 50ish a cat is now at topend how long can the maintan/sustain it, enter............"SPEED ENDURANCE" That is why sprinters run repeat 300's in training, they are building SPEED ENDURANCE, nobody can run a fast 100m without it..
Usain Bolt started out as a 400m guy, but was too lazy (his words) for that event, so he spent years running the 200. When you train for 200m your SPEED ENDURANCE will be superior to just 100m guys. So when he finally started running the 100 his SPEED ENDURANCE was on a whole other level. That is why he's on a whole other level, he decellerates very little in a 100m.
The great Tommie Smiht was like that, he was a 400/200 World Record holder who once ran down soon to be Olympic 100m winner Jimmy Hines on a 4x1 anchor leg. He didn't decellerate like a normal human being.
As we have seen fica knows absolutely nothing about any of this stuff, talking how soccer cats run MPH......hahahaha~~~ Totally ignoring the 20 pounds of helmet/pads pro footballer carry around and a football. Put 20 pounds on little 150 pound soccer ites, good luck.
