Guillermo is an associate researcher at the Andalusian Centre for Developmental Biology and has held an associate professorship at the Pablo of Olivade University since 2003. He has a BsC in Sciences and a PhD in Science from the University of Cordoba, Spain. Having completed his PhD, he undertook postdoctoral study on the physiology of neutrophils at the Rayne Institute, University College London. He is also a Principal Investigator in several Spanish Government funded studies about the role of the metabolism and antioxidant systems in ageing and physical activity.
A two-year study has shown that Ubiquinol, an electron rich form of the coenzyme Q10, can help players perform better and manage physical stress at the highest levels of football. Elite players from Spain’s Athletico de Bilbao took the supplement over two playing seasons and were shown to have higher levels of total CoQ10 in plasma as well as lower levels of creatine kinase and cortisol, even in the middle of the season when competition pressure was at its highest. These players were able to run further and maintain higher mean speeds during football matches. Guillermo reveals the study’s full results and demonstrates that higher levels of CoQ10 in plasma can prevent muscle damage and improve physical performance among football’s elite players.
