Wardenaar is an assistant professor at the College of Health Solutions since September 2017 with expertise in Performance Nutrition.
Floris Wardenaar was born in Amsterdam, the Netherlands. Despite the fact that there was no previous history of competitive sports within the family, all the brothers were competitive in different areas of sport. At the age of 14, he started cycling, both on the road and the track. From that moment on his interest in performance nutrition grew. During his second year as a junior cyclist he was selected for the newly formed National track cycling team. As part of his cycling career he collected more than 30 stage places and victories.
Wardenaar studied nutrition and dietetics at the Hogeschool van Amsterdam (HvA, Amsterdam Applied University) with specific interest in sports nutrition. During this bachelor program he followed an internship at NOC*NSF writing the brochure: What to know about nutrition and Sydney in preparation for the Olympic Games at Sydney 2000. Together with his bachelor degree he received his post bachelor degree of sports dietetics which was granted by NOC*NSF.
Following this, Wardenaar started a master's program at Wageningen University in human nutrition and physiology. During the second year at Wageningen, he founded his own consultancy firm in sports nutrition advice and during the third year he was full-time vice-president of the Dutch Chamber of Student Associations (LKvV). Subsequently he followed an internship at the Department of Kinesiology at the University of Texas in Austin and wrote his master’s thesis on the interaction between alcohol consumption, exercise and blood glucose levels at SENECA, expert centre of HAN Sports and Exercise Studies at the HAN University of Applied Sciences at Nijmegen. He graduated in 2005 both in nutritional physiology and in nutrigenomics.
At the start of 2006, Wardenaar took up the post of lecturer at the Institute of Paramedic Studies at the HAN. From that moment he was also asked to cover the sports nutrition position of the professional TVM speed skating team as part of an agreement between this team and HAN Sports and Exercise studies. In 2007 he was added to the nutrition team of the Dutch Olympic Committee (NOC*NSF) and from 2010 he became a member of the research group of the professorate (in Dutch: lectoraat) Sports, Nutrition and Health. At the beginning of 2011 he moved completely from paramedic studies to Sports and Exercise studies. 2012 saw him take on a team leader role as senior lecturer of the expert team Sports and Exercise Nutrition with responsibility for education, research and consultancy within the Institute of Sport and Exercise. During this period, he was also president of the Dutch Association of Sports Dieticians.
In September 2012 he commenced his doctoral project in cooperation with Wageningen University, which was partly financed by a regional grant Eat2Move. At the beginning of 2013 he became program manager of work package 3 within Eat2Move and from 2014-2017 he was team leader of the Team Nutrition of the Dutch Olympic Committee.

Since 8 September 2017, I have joined the College of Health Solutions. I was partly appointed at the Sun Devil Athletics as sports nutrition advisor (2017-2019). My research focuses on the nutrition and hydration needs of athletes and active populations living in a hot and dry environment.
