Dr Christopher Kirk PhD FHEA CSci CSCS
Lecturer in Sport and Exercise Physiology
Summary
I am a BASES Accredited Sport and Exercise Scientist, NSCA certified strength & conditioning coach and researcher. I teach exercise physiology and strength & conditioning on both undergraduate and postgraduate degrees. My interests are in the application of physiological first principles to improving combat sports performance and athlete health across the lifespan, with my main focus being MMA.
About
I completed my BSc (Hons) here at Sheffield Hallam in 2003, my MSc (by Research) at the University of Central Lancashire in 2014, and my PhD at Liverpool John Moores University in 2022. I have been teaching and lecturing since 2006, first in a number of FE colleges and then at the University of Derby before joining SHU in 2020. I use my breadth of experience to make the science of sport and exercise accessible and applicable for all our students to allow them to achieve their goals and pick their own futures. In my applied practice I have provided S&C coaching and physiological interventions for a wide range of sports including rugby, American football, GAA, taekwondo, MMA, Brazilian jiu-jitsu, para-swimming, athletics and Olympic weightlifting. My practice includes novice athletes and international standard performers, but I approach each with the same goal - to utilise physiological first principles to improve their performance and health throughout their lives. My research is focussed on the performance and health of combat sports athletes, with MMA being my main area of interest. I work closely with the International MMA Federation, the English MMA Association and I maintain strong links with gyms, coaches, promoters, governing bodies and research groups across the globe.
