With a single genetic variation, some of us are fast, moderate or slow caffeine metabolisers. So should competitive athletes be doing genetic testing to inform their race day caffeine strategy? Just last week, a new meta-analysis was published that tries to answer this question by bringing together all the studies published to date. Two of the authors, Gabriel Barreto and Dr Bryan Saunders from the University of São Paulo are here to explain their research and the implications for runners, cyclists and triathletes.
