Postgraduate Research Student

Stefan Kolimechkov is undertaking a dual degree MPhil/PhD in Human Sciences at the University of Greenwich, London. Stefan joined the University after a successful application at the end of 2021, and he is in his fourth year now. His current research focuses on the effects of microcurrent with and without resistance exercise on muscle strength, body composition, and functional capacity. Stefan is supervised by Professor Fernando Naclerio and Dr Marcos Seijo at the Centre for Exercise Activity and Rehabilitation within the Institute for Lifecourse Development, University of Greenwich.

Educational Background

2007-2011, Bachelor's degree in Sport and Physical Education, National Sports Academy, Sofia, Bulgaria
2011-2012, Master's degree in Physical Education, National Sports Academy, Sofia, Bulgaria
2015-2018, Doctor of Philosophy, Physical Education, National Sports Academy, Sofia, Bulgaria

Professional Experience

Stefan worked as a gymnastics coach from 2008 until 2012 at the Levski Gymnastics Club in Sofia, Bulgaria. During this time, many of his students won medals and certificates from club, regional, national and international gymnastics competitions. Stefan competed as a gymnast as well, representing his university team A-Gym NSA Gymnastics Club in many National Gymnastics Championships. In 2012, Stefan was ranked 4th in the country on the Men’s Rings Final in Bulgaria at the National Gymnastics Championships.

In 2013, Stefan moved to work and live in London. He started coaching gymnastics at the Elite Gymnastics Academy CIC, and he also provided gymnastics coaching and volunteered as a PE assistant at St Edmund’s Primary School in London. Between 2015 and 2018, Stefan did a part-time PhD in Physical Education at the National Sports Academy in Bulgaria. His PhD thesis focused on the nutrition and health-related physical fitness of primary school children engaged in artistic gymnastics, and he managed to fund his project himself while working in London as a gymnastics coach. In 2018, at the age of 30, he was officially admitted to the degree of Doctor of Philosophy after an excellent defence of his Doctoral thesis.

In 2020, Stefan obtained his British citizenship. He holds a Qualified Teacher Status (QTS), Chartered Activity and Health Practitioner MCIMSPA (ch) status, and Level 3 British Gymnastics Coaching Qualification, and the status of Level 6 Personal Trainer, Advanced Health and Exercise Specialist awarded by the European Register of Exercise Professionals (EREPS). Stefan provided gymnastics coaching in London as part of his personal training business (STK SPORT) between 2013 and 2022.

In 2022, Stefan founded the Kensington & Chelsea Gymnastics Academy Ltd to bring gymnastics to the community in the Royal Borough of Kensington and Chelsea, London. His main goal is to help people recognise and experience the joy of doing gymnastics in order to sustain a healthier and more fulfilling lifestyle. In 2023, Stefan was awarded the World Physical Education Ambassador award by the Federation Internationale d'Education Physique et Sportive (FIEPS). In August 2023, Stefan successfully completed the International Summer School ‘Research Methods in Sports Science for Interdisciplinary Approaches’ at the German Sport University Cologne in Germany. In 2024, Stefan was recognised as a Fellow of the European College of Sport Science (ECSS).

Research / Scholarly interests

Stefan’s scientific interests are in sport, health and exercise sciences, and include various sub-fields, such as health-related physical fitness, successful ageing, masters athletes, nutrition, gymnastics, and physical education. As part of his current and previous degrees, Stefan has published peer-reviewed journal articles on these topics, and he has also presented research in international conferences around the world, including the United States of America, United Kingdom, France, Luxembourg, Spain, Czech Republic, Finland, Bulgaria, Romania, and Turkey.
Stefan developed sports software called ‘BeepShuttle’ with the help of his past supervisors Prof. Lubomir Petrov and Professor Albena Alexandrova. The software administers the 20m shuttle run test, calculates the predicted maximum oxygen consumption (VO2max), and provides a percentile score for each participant based on age- and gender-specific norms.
