Dr. Allyn Byars (Angelo State University, San Angelo, TX), Drs. Mike and Lori Greenwood (Baylor University, Waco, TX) and Dr. Warren K. Simpson (Hardin-Simmons University, Abilene, TX) showed that, when consumed by healthy subjects instead of water prior to exercise, EMPACT™ sports drink enhanced indices of cardiorespiratory fitness (specifically VO2max and time to exhaustion).* Study was at least partially funded by Mannatech.
