SwiMetrics of a High School Water Polo Player

Huntington Beach High School swimmers and water polo players were tested on January 2nd 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 athlete in the video).

The athletes were tested in a variety of 20-yard race-pace swims including pulling with a pull buoy, sprint freestyle and dribbling with a water polo ball.

In the video shown below, the high school water polo player is swimming at 1.8468 meters per second at that point in his stroke.
