Running really "bouncy" = higher top speeds?

I’m sure most of you know what I mean by running bouncy. Basically, staying high on the balls of your feet, and really bouncing up and down high, sort of like you’re bounding.

I was watching powell’s 9.75 run and got reminded of running like this. Does it increase your stride length? and when I run like this when im just doing warm up strides, it “feels” sort of faster.

thoughts?

It depends on the model you use, if it is speed dynamics then using the calf through the range is a no no.

Is the calf the strongest muscle in the body, if so why not use it.
