Dr. Richard Metcalfe is a Senior Lecturer in Sports and Exercise Sciences at Swansea University, working within the Technology, Exercise and Applied Sports Medicine (ASTEM) Research Group in the School of Engineering and Applied Sciences. He joined Swansea University in October 2017 after working as a Lecturer in Exercise and Health at Ulster University from 2014-2017.
Dr. Metcalfe earned his BSc (Hons) in Sports and Exercise Science from Heriot-Watt University in Edinburgh in 2010, followed by a PhD at the University of Bath (2010-2015) under the supervision of Dr. Niels Vollaard and Professor Dylan Thompson.
His primary research focuses on the health benefits of high-intensity, time-efficient interval training (HIT), particularly developing optimized protocols for sedentary populations. Over the past decade, his work has led to the development of reduced-effort HIT (REHIT), an exercise protocol that takes no more than 10 minutes to complete (twice weekly) with just 40 seconds of high-intensity exercise. This approach aims to remove barriers that prevent sedentary individuals from gaining health benefits through regular exercise. His expertise spans exercise physiology, exercise metabolism, high-intensity interval training, Type 2 diabetes, insulin resistance, and training adjustments.
Dr. Metcalfe's recent publications demonstrate a strong focus on practical, time-efficient exercise interventions with applications for metabolic health, cardiovascular function, and performance optimization. His work frequently examines how minimal exercise can produce significant health benefits, with particular attention to REHIT protocols, nutritional timing, and physiological responses to various exercise modalities.
Dr. Metcalfe is actively involved in postgraduate supervision, currently overseeing multiple PhD projects related to nutritional strategies in rugby, youth athlete development, exercise impact on cardiometabolic health, and exercise serum effects on cancer cells. He has also supervised several MSc students whose work focused on breakfast timing effects on performance, alternative rugby for at-risk populations, and children's fitness.
His research has been featured in BBC Horizon documentaries ("The Truth About Exercise" in 2011 and "The Truth About Getting Fit" in 2018), and he regularly contributes to The Conversation with articles on fitness, exercise physiology, and health.
