Sliding Fila… What?

Time to simplify things a little.

I often get asked about the Sliding Filament Theory; what is it, how does it actually work?

It sounds seriously complicated, and a lot of jargon words, but generally I find most people get the gist of what is going on during muscle contraction. They are just missing some perspective.

So I’ve made you a quick 5 minute video to chunk down the Sliding Filament Theory into the most simplest, jargon free description I possibly can.
