For forty years, scientists at Wacoal Human Science Research Center in Kyoto, Japan have studied kinesiology, the science of human movement. They have tested over 35,000 people and analyzed injuries relative to warm-up and cool-down periods. They have come to understand the mechanics of joints and muscles in minute detail. This exhaustive study of body movement has culminated in over 15 U.S. patents and CW-X® Conditioning Wear®.

In a study in Kyoto, Japan, electrical pulse activity of the muscles (muscles firing into motion) was measured electromyographically. Unsupported and partly supported legs both show frequency decrease during exercise, indications of fatigue. Legs supported by CW-X® showed negligible frequency decrease.

In a study in Montpelier, France, differences in fatigue in runners wearing shorts, regular spandex tights, and CW-X® Conditioning tights were measured comparing VO2 oxygen uptake levels over 15 minutes of running at 80% of maximal effort. When wearing CW-X® tights the results showed 26% and 36% lower oxygen usage compared to regular tights and shorts respectively, indicating lower energy expenditure in CW-X® tights.
