On January 2nd, 2009, a pool and open water swimming athlete from the Irvine NOVA Masters Swimming, was tested using SwiMetrics, the world's most sophisticated swimming analytical tool for swimmers, water polo players and triathletes.
SwiMetrics measures and records the velocity (speed in meters per second) and force (in kilograms) at specific points in the swimming stroke. The test results are synchronized with DartFish software to superimpose velocity and force curves (60 times per second) with an underwater video of the athlete.
The vertical green line in the middle of the graph indicates the athlete's position on the video (shown below). The real-time velocity data at every point in the swimming cycle is represented by a "Velocity Curve" (the continuous white line shown below the swimmer in the video).
The athlete was tested in a variety of 20-yard race-pace swims with a regular swim suit. In the video shown below, the athlete is swimming at 1.215 meters per second at that point in her stroke.
