Professor Mayur K Ranchordas DProf, SFHEA, CSCS, SENr
Head of University Research Ethics and Professor of Applied Human Nutrition for Sport and Exercise
Summary
I am the Head of University Research Ethics and Professor of Applied Human Nutrition for Sport and Exercise. I teach both at undergraduate and postgraduate Sport Science courses and I also work as a sport nutrition consultant who has supported several Olympic and World Champions, Premiership footballers and professional boxers and cyclists. I have a keen interest in how sport nutrition science can be translated to "food on a plate" that can help athletes enhance their performance.
About
Mayur has an undergraduate degree in Sport and Exercise Science and Masters degree in Exercise Physiology both of which were gained from Sheffield Hallam University. He has since completed his IOC Diploma in Sport Nutrition, is a Certified Sports Nutritionist from the International Society of Sports Nutrition and holds a Professional Doctorate in Applied Sport Science specialising in Exercise Physiology and Sport Nutrition. Mayur has been teaching Sport Science at both undergraduate and postgraduate level at Sheffield Hallam for over 17 years and has combined this by working as a Sport Nutrition consultant and applied sport nutrition research. Mayur has worked for several Premier League Clubs including Bolton Wanderers Football Club, Newcastle United Football Club, Stoke City Football Club as well as supporting Gold Medallists and World Champions competing in Olympic Sports from his time working at the English Institute of Sport. Currently, Mayur provides sport nutrition support to Premier League footballers as well as Premier League Referees (PGMOL). Mayur also supervises PhD students and is an active researcher in sport nutrition. His main areas of research are in the effect of sport supplements on performance and recovery and the effects of nutrition on football performance and recovery.
Specialist areas of interest

Academy of Sport and Physical Activity
College of Health, Wellbeing and Life Sciences
Sport Nutrition and Exercise Physiology/Sport and Exercise Science
I teach on the BSc Sport and Exercise Science and MSc Applied Sport and Exercise Science programmes.
I am the module leader for Level 6 Applied Physiology and Nutrition of Sport and Exercise. I teach on the Level 7 Improving Performance and Physiology and Nutrition module and the Level 7 Professional Practice in Sport and Exercise Science modules. I supervise Level 6 and Level 7 project students.
Research
My research portfolio sits on a continuum where sport sits on one end of the spectrum, and health and wellbeing on the other.
The thread of my research explores how nutrition, food and dietary supplements can enhance performance and recovery at the sport end of the continuum and at the opposite end, how these methods can enhance health and wellbeing. More specifically, the majority of nutrition strategies that can help athletes perform more work, enhance performance and recover faster have very clear applications in enhancing health and wellbeing at the other end of the spectrum too. For instance, strategies that can reduce inflammation and muscle damage in elite athletes training extremely hard can also have transferrable health benefits in reducing inflammation in diseased populations thereby enhancing wellbeing.
