At a Glance
About
I am a sport physiologist. I have worked on heat and hydration for specialist police officers, fluid balance for elite squash players, conditioning for boxers across 15 world championship contests, and recovery in Premier League football.
I test athletes, run the research behind the testing, and coach the people who use it. I am a qualified England Athletics coach, working across athletic events from youth to senior age groups. I have published 50+ peer-reviewed papers with 1,774 citations and an h-index of 26, and supervise seven doctoral projects. Two sit inside professional football clubs, Aston Villa FC and Sheffield United FC, and two more are with La Trobe University in Australia and Auckland University of Technology in New Zealand.
Through Boxing Science, which I co-founded in 2014, I have delivered workshops to more than 500 coaches across the UK, Europe, North America and Asia, on a platform drawing over 300,000 unique visitors a year and over 11 million YouTube views. I have provided expert commentary to The Times, the Wall Street Journal, the BBC, Sky Sports, Live Science and Runner's World, and my work has been read over 225,000 times on ResearchGate.
I am Associate Professor of Sport Physiology and Performance at Sheffield Hallam University, a Director of the Chartered Association of Sport and Exercise Sciences and Chair of its Physiology and Nutrition Division, Ethics Lead for the School of Sport and Physical Activity, and a Chartered Scientist. In 2021 I received the CASES Applied Practitioner Award for sustained, outstanding and innovative sport science service delivery.
Applied Projects
Conditioning for World Championship Boxing
Boxing Science
- Problem
- Conditioning built on tradition rather than evidence, in a sport with weight-making and twelve-round demands.
- Measured
- High-intensity interval responses, load-velocity profiling, and weight-making physiology.
- Outcome
- Scientific support across 15 world championship contests, for athletes including Anthony Joshua OBE and Fabio Wardley, and practice adopted by more than 500 coaches internationally.
Recovery in Elite Professional Football
Aston Villa FC
- Problem
- Recovery methods widely used, thinly evidenced, and expensive.
- Measured
- Recovery interventions against performance and wellness outcomes in a Premier League environment.
- Outcome
- A £40,000 funded doctoral programme embedded in the club.
Hydration and Fluid Balance in Elite Squash
England Squash
- Problem
- Fluid and sodium losses were undocumented in squash.
- Measured
- Fluid balance, sodium losses and training-day hydration practice.
- Outcome
- Published individualised hydration guidance, and a systematic review of the physiological and nutritional demands of the sport.
Heat Acclimation Before the 2014 World Cup
Professional soccer match official
- Problem
- A northern European match official heading for the heat and humidity of Brazil, with no environmental chamber and a schedule built around training and competition.
- Measured
- Tympanic and mean body temperature, plasma volume, sweat rate, high-intensity running performance and thermal comfort, before and after the intervention.
- Outcome
- Thirteen sessions over eighteen days combining isothermic running with hot water immersion. Plasma volume rose 7.1%, sweat rate 0.9 L/h, exercising temperature fell 0.6°C and high-intensity running improved 29%. Published as a case report in SpringerPlus.
Operational Body Armour in Specialist Police Officers
Metropolitan Police Physical Protection Group
- Problem
- The physiological demands and the lived experience of wearing body armour on operations were not documented.
- Approach
- Authored the foundational exploratory report in 2020, applying doctoral research on thermoregulation to the operational question, then convened and oversaw a multidisciplinary team for a commissioned study of 147 officers using a novel story stem method.
- Outcome
- Built the force's understanding of what operational body armour asks of the people wearing it.
