NASA also demonstrated that a low-profile zipper, ultrasonically bonded into the fabric and hidden inside the suit, generated 8 percent less drag in wind tunnel tests than a standard zipper.
Freestyle Innovation Similar in style to a wetsuit, the original LZR Racer covered either some or all of the torso and legs, depending on the preference of the swimmer or the event it was being used for.
The greater the coverage over the body, the more drag could be reduced. Within a year of its release in early , the LZR Racer achieved worldwide fame as the most successful swimsuit ever made. Within a month, athletes wearing the suit broke 13 world records.
Out of the 25 world records broken at that Olympics, 23 were accomplished by swimmers wearing the suit. Speedo, undaunted by the ban, has continued to innovate using the same technology developed in part by its collaboration with NASA. To put together the LZR Racer suit, Speedo used ultrasonic welding instead of traditional sewing to bond the fabrics, as the high profiles of normal seams act as bumps and induce drag. The suit therefore appears seamless. For the same reason, the zip fastener is made to face toward the body so that the flat underside of the zip teeth faces externally, whereas the raised teeth face inwardly.
Conventional competitive swimsuits only use a single layer of fabric with low profile seams to minimize skin friction drag. There are limitations to this approach, however. In general, the greater the surface of the body that is covered with a low drag material, the greater the reduction in skin friction.
Unfortunately, low drag materials usually have high tension. Speedo came up with a solution: instead of a single material, they use composite layers consisting of materials possessing different elastic and surface properties.
Separate panels are then laminated onto the outer surface of this base layer. These panels are made of thin sheets of polyurethane, a more rigid material than the base fabric. Specific locations of the panels are customized to the type of strokes. In addition to these panels, an internal core stabilizer — an inner core layer of stretchable fabric bonded to the inner surface of the base layer — is used to tighten the abdomen and the lower back, and is supposed to provide a corset-like grip, which helps to reduce form drag and improve core stability.
The challenge will be deciding where to draw the line. After all, we wish to see a fair game between athletes based on their athletic prowess and technique, and not a competition between technologies and their respective inventors and sponsors.
