Dr. Katharina Wirnitzer
Dr. Katharina Wirnitzer
is an Austrian sports scientist and a university lecturer in sports science. Many years ago this keen sportswoman was able to turn her hobby into her job and lives what she loves and loves what she does: outdoor and endurance sport.
Her bikeeXtreme research project investigated the endurance and stress profile of mountain bikers during the Mountainbike Transalp Challenge, a race staged over eight days. This made her the first scientist in the world to investigate i) a mountain-bike marathon, ii) a mountain-bike stage race, iii) female mountain-bikers in stage races and iv) a purely plant-based diet used by participants in endurance events taking place over several days.
Her book about extreme stress experienced during mountain-bike races staged over several days was published in 2009 (bikeeXtreme – Performance determining factors and vegan nutrition pattern to successfully complete the Transalp Challenge).
In 2014 she reached a milestone with the publication of the world’s first purely plant-based diet for endurance athletes (after it had been scientifically recommended as the optimum nutrition strategy for the first time in 1982). This case study was the foundation stone: now we have to build on it.
Dr Wirnitzer has designed the NURMI-Study as a follow-up to her mountain-bike field study and has set up a second pilot study in order to build on this foundation stone and create a broad basis for well-founded evidence of the link between endurance and diet.
