In Colorado Springs, a 47-year-old masters swimmer was tested on 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. The real-time velocity data at every point of the swimming cycle is represented by a 'Velocity Curve' (continuous white line below the swimmer).
The swimmer was tested in a variety of 20-yard race-pace swims including pulling with a pull buoy, butterfly and head-up swimming so he could identify the strengths and weaknesses of his technique at every point in his stroke.
His velocity was 1.2636 meters per second at the particular point in his stroke captured below.
