slowmo in slowmo

To the bemusement of neighbours and passers-by I spent a few minutes the other day filming myself running backwards and forwards past my house in an attempt to discover what my feet are doing when I run. To try to capture my typical running form I did the filming after I'd got back from an easy 5km run. I arranged each "pass" so that there were a few metres of running either side of the camera's view and I tried to keep to my usual slow-ish pace.

I don't own a video camera so I set up my trusty little Panasonic Lumix snappy camera, which has a movie mode, on a tripod at the bottom of my driveway. The camera saves the movie as a .mov file. To create a slow-motion sequence I loaded the file into QuickTime, exported selected bits to image sequences (sets of jpeg still images), then imported each of these back into QuickTime at 6 frames per second.

And here is the result...



The verdict ? Well, it seems that I land with a mid-foot strike. This came as quite a surprise. When I'm running, I feel like I'm landing towards the front of my foot. But the camera doesn't lie and it could be that my impressions were influenced more by what I thought I should be doing rather than by what I actually was doing.
