A SINGLE CAMARA PANNING VIDEO METHOD TO OBTAIN THE BASIC CHARACTERISTICS OF SPEED RUNNING IN SPRINT RUNNING

The purposes of this study were to develop a method to achieve basic kinematics parameters in sprint competition situation suitable for normal coaching usage. 1) A simple method 10 obtain the basics characteristics of speed running -strides length and strides frequency-over an entire 100m sprint running using only one simple video camera. 2) A procedure to apply in track and field without using any placing mark on the track, but try to use the natural marks placed on tracks (50m and 60m starts, and the 100m 11 Om and 400m hurdles marks, podiums, anemometers, publicity placards, jump boxes, etc ...). The results revealed similarities between the data obtain from the photo-cells and from one panning video camera, suggesting that this method used by us to calculate the distances is valid. In addition to being used for sprint this technique can also be used to buill speed curves in hurdling races, approach running of jumps (long, triple, pole vault) and javelin throwing
