The second thing then is some sort of performance metric.

So this could be something simple like a leg press machine or more complex like a single leg squat or anywhere in between.

And within that, you want to identify whether or not the muscle is capable of moving fast or

moving strong, and can repeat that performance over multiple repetitions.

Helping you interpret your score on a movement screen is really challenging without having a lot more individual context.

So what I'd like to do is give you some more straightforward and specific examples from the metrics of speed, power, and strength.

In sticking with the theme of this show, I wanted to give you some context as to what the best in the history of the world look like for muscle speed, power, and strength.

In my opinion,

No one typifies muscle speed more so than 100-meter sprinters.

This is the quintessential best test in the world of maximum velocity.

And so when we look at the best...

Two names jump off the chart.

Of course, from the female perspective, this is Flojo, the American sprinter.

And then from the male perspective, no one comes close to Usain Bolt.

So how fast were these two individuals?

Well, a little bit of context here.

It took about 40 years and 11 individual men to drop the world record in the 100-meter dash by about two-tenths of a second, from 9.95 to 9.74.

bolt did nearly the same thing all by himself he dropped the world record by 0.16 seconds all the way down to 9.58 seconds over the course of his career so he himself represented almost the same progress as the entire field made in 40 years that's how much faster he was than anybody else ever before him and still to this day no one's come even close to matching that feat

In fact, only two people ever have run 100 meter dash in under 9.7 seconds, which means Usain Bolt is over a tenth of a second faster than anyone ever in the history of the competition.

Now, there's actually a lot of interesting people who try to understand and examine why he's so much faster than anyone else.
