When running this program, the program is started; the swimmer pushes the front panel button and begins a swim at maximum speed. Then after a short interval at peak speed a resistive force ramps up from zero to a force which stalls the swimmer’s forward motion. This is the maximum thrust the swimmer can generate. After the stall, the force is released, the swimmer stops swimming, lays over on the back and the rewind mechanism pulls the swimmer to the starting point. The recorded values of distance, speed, force, and power are graphed. Distance, peak speed, stall force, and peak power are captured and displayed on digital meters. All values may be dumped to an Excel spread sheet for further analysis. Screen display also may be copied and pasted to a word document for a permanent graphical record for the swimmer’s file.

Speed and Peak Power Trial - Free Style. 

Unresisted speed is measured after the push off and before resistive force is applied.  Stall force is the maximum thrust the swimmer can generate.  Peak Power is the greatest mean power generated over one or more complete strokes.  Distance is shown for reference only in upper trace as a continuously increasing value from push off to end.  Any channel can be turned off by double clicking the channel tab to give greater readability of the remaining channels.
