Dr Justin Roberts

Justin is a Principal Lecturer in Sport and Exercise Sciences, with a focus on applied and health-based nutrition. His interests encompass a wide range of areas including how both dietary and nutrient interventions can impact on adaptations to exercise, both in terms of physiological and metabolic health, as well as enhancing sports performance and recovery.

Background

Justin joined the Sport and Exercise Science team at ARU in 2014, and is a researcher with our Cambridge Centre for Sport and Exercise Sciences. He is an accredited Sport and Exercise Physiologist and Chartered Scientist with the British Association of Sport and Exercise Sciences (BASES) and a Member of the American College of Sports Medicine (ACSM). He is also a Registered Nutritional Therapist with the British Association of Applied Nutrition and Nutritional Therapy (BANT) and the Complementary and Natural Healthcare Council (CNHC).

With over 20 years’ experience in sport and exercise physiology and nutrition, Justin has worked at various institutions including the British Olympic Medical Centre (London), Brunel University (where he completed his PhD), Victoria University (Melbourne) and the University of Hertfordshire.

Justin specialises in applied nutrition, with a central aim of exploring dietary and nutrient/supplementation strategies to support exercise training and recovery, cardio-metabolic health and sports performance. His current research interests involve the use of ‘calorie restriction mimetic’ nutrients on physiological mechanisms associated with fat oxidation and weight management.

Research interests

• Effectiveness of green tea extract on fat oxidation, health biomarkers and exercise performance
• Use of intermittent fasting and ketogenic diets on fat oxidation and exercise adherence
• Assessing the benefit of high protein diets in trained athletes on recovery, satiety and adaptive gains

• Nutritional strategies to minimise gastrointestinal endotoxemia from endurance and ultra-endurance performance
• Nutritional strategies employed by athletes with particular reference to team sports and ultra-endurance individuals
