The Westuit Performance Test Eight suits were tested on two different subjects. All sizes were selected based on the manufacturer provided fit charts. The Westuit Performance Test This box records the data that drives the Swim Power System. The swimmer covers a length of the pool while the cord spools out behind them. The Westuit Performance Test Sokolovas’ Swim Power machine records velocity as the swimmer crosses the pool. The Westuit Performance Test After a length of the pool, the subject returns to the start and the machine is reset. The Westuit Performance Test Sokolovas records video of the swimmer while they complete each length of the pool. The Westuit Performance Test To help standardize their strokes, the subjects put a pull buoy between their ankles. The Westuit Performance Test The stroke video is overlayed with the curve of their velocity, the small squiggly line on screen. The Westuit Performance Test Sokolovas uses this underwater camera. The Westuit Performance Test The swimmers progressively increase their effort level throughout each test. The Westuit Performance Test The push-off from the starting wall and final 5 yards of each length are both subtracted from the data so the stroke itself, not the walls, is represented in the data. The Westuit Performance Test The subjects swim with a buoy between their ankles to standardize the kick. They were also tested without a suit to create a baseline to compare to each suit. The Westuit Performance Test Sokolovas sits with the subjects and analyzes their stroke by linking changes to velocity with specific moments in a stroke. The Westuit Performance Test For example, when velocity dips, that is an indicator that something is wrong with the swimmer’s technique. Linking the velocity and video allows him to identify specific problems, which the swimmer can then address in training.

The benefits of triathlon wetsuits have largely remained unquantified until now. With help from one of the world’s leading sports science and physiology experts,
Triathlete conducted testing on eight wetsuits to determine the actual gains a swimmer experiences by wearing specific suits. See a breakdown of the results above, and read the complete results here.
