the need for the product to be non-invasive and non-stressful came directly from the inventors’ experience in soviet athletics teams and the testing methods they used. at that time soviet athletes were tested to assess their condition once or twice a year, with the tests taking place in a hospital. the tests included highly stressful methods such as muscle biopsies and exercising till exhaustion. since the results became available several weeks later, and the athletes took a long time to recover, they were of no practical use to the coaches. the technology and techniques that eventually became omegawave products were therefore designed with the specific purpose of being quick, non-stressful and non-invasive, and to provide results that were easy for coaches to interpret. published studies appear to indicate that these non-invasive methods are, as intended, as reliable as the more invasive methods.
