VIDEO: Check Out What a Swimmer Looks Like at a MusculoSkeletal Level

Ever wondered exactly what your arms and legs were doing during each of the four primary competitive swimming strokes: backstroke, breaststroke, butterfly, and freestyle?

We came across this video today on Facebook, and found the original source (as best as we can tell) on a YouTube channel called “anybodytech” from 2008.

The video looks at a muscular and skeletal level at what is happening during each of the four major strokes. When a muscle turns purple, that means it is activated.

The research for these videos was done by a doctor Nakamisha at the Tokyo Institute of Technology. In the video’s info, there is a link to see more information on each video.

If you were ever wondering why, exactly, butterfly is so exhausting, this video gives a good indication – the arm muscles are constantly activated. Unlike the other strokes, there’s never any significant period of relaxation.

if you are really a geek you can listen to a tough lecture on how their analysis system was developed:

What is unknown is the swimmer used. Obvious differences in technique will play a role in which muscles are activated. Would love to see:

Ledecky for free
Phelps fly
Pearsol back
and a variety for breast depending on technique

ChestRockwell

I’d like to see the musculoskeletal breakdown of this stroke:

Do yourself a favor and take a few minutes to watch that. It is a true gem of the internet and something any swimming fan will enjoy.

Hey i’ve seen this before in the Olympics. He didn’t start with the cross-stroke but switched to it toward his final sprint. Now i know where he went to train.

So that’s how Thorpe did it.

You see, when the arm goes under water, the shoulder loses the ability to pull backwards…..

It’s too bad Thorpe didn’t use this technique, because it he had, he’d be injury free.

I know that because the the internet said so.
