[EN] Jem Arnold & Andrew Sellars on the Theory and Practice of Physiological Threshold || Episode #190
Jem Arnold: Jem is a PhD student in Kinesiology at the University of British Columbia, in Vancouver, Canada. He is also a physiotherapist and cycling coach. Jem is interested in all kinds of topics related to endurance sport performance and his growing specialty is in muscle oxygenation with near-infrared spectroscopy. His PhD work is with athletes with flow limitations of the iliac artery, which he has first-hand experience with, having the condition himself.
Andrew Sellars: After 5 years as a competitive swim coach, and a Bachelor’s Degree in Human Performance, I pursued a Masters Degree in Education (coaching studies) at the University of Victoria, where I was Assistant Coach to Dr. Peter Vizsolyi at the Varsity Level. I then pursued a career in Medicine, and completed specialized training in Anesthesia, where I continued to develop a deeper understanding of cardiopulmonary physiology.
My passion for endurance sport, and coaching, led to the development of the Balance Point Racing Team, where the primary focus was on applying the most up to date research and testing methods to the development of individualized training plans for endurance athletes. As we continued to push the boundaries of what the testing equipment was capable of, I shared a vision with a young athlete, Peter Obrien, about what the future of physiologic testing could look like. With Peter, we went on to found VO2 Master, in order to create the first ever wireless, portable, and affordable VO2 testing equipment in the world.
