Goal

Specify what the swimmer motions determine swimming speed in a greater degree.

Solution

Two cameras (over- and underwater) were used to determine what motions of a swimmer influence the swimming speed in a greater degree. Both cameras were put so that to move along a lane with a steady speed and fix any changes in the swimmer motions. Swimming time was measured by a timer switched on at start. The main challenge was in securing precise measurement of a change in swimming speed. To do it we had to know the distance covered within a certain period of time, provided that the athlete used arm pull of a type being evaluated. Control gage of 1 m was put in the pull. It made measurement of swimming speed possible, and all calculations were provided automatically.

We also suggested further development of this video-capture motion analysis. It`s known that the angle under which the swimmer enters the water after start can influence the swimming speed, and the angels under which the swimmer`s arms enter the water also do. This method makes it possible to evaluate how swimming speed depends on angles of entering.
