Researchers first discovered the science behind Zona Plus therapy in the 1970's while trying to solve a completely different problem for the U.S. Air Force. The U.S.A.F. found many of its fighter pilots were experiencing temporary vision loss, as a result of sudden G-force on the pilot. In an effort to find a solution to the problem, the Air Force commissioned Dr. Ronald L. Wiley, a respected cardiopulmonary physiologist.
Dr. Wiley and his team discovered that a certain type of isometric handgrip therapy not only worked wonders to increase pilots' G-force tolerance, but it also offered another important side benefit. For some pilots the therapy actually reduced their blood pressure! Researchers spent years testing and refining the therapy, and in 2006, Zona Plus was first introduced in the USA.
