I bullied Team Tervin into posting to "Bright Cove" so we can see their swim analysis video better.

I also asked for a video explanation and here it is:

Velocity Meter-Push-off and Glide Analysis -TeamTermin.com

The black line that scrolls across the graph during playback is the synchronized position with the video.

This video demonstrates two important components about the drag forces associated with water. You will notice that the instant the swimmers feet loose contact with the wall, velocity immediately begins to decline very quickly. (exponentially) The next feature is based on the mean swimming speed of the swimmer. You can use the curve to precisely find the velocity/time from the wall where the breakout should occur, so you can begin swimming at the intersection of your mean swimming speed and place on the curve where that speed occurs. The goal being to not spend any time below your mean swimming speed by gliding to far from the wall.

Here is a direct link to a bigger version of the video: [Link]

[I receive no compensation or gifts for posting this info. I posted it because I think it way cool when you mix swimming with mathmatics. I will be posting two more later. One is for the breststroke.]
