Today is the sixth video and audio-only rebroadcast from the 2016 Huffines Discussion. Up today in our series is Dr. Peter Wagner from the University of California San Diego. Dr. Wagner's talk is called "The Long Debate About VO2 Max - Does the Limit Come from the Heart or the Periphery?" and considers the arguments about whether oxygen consumption is regulated by cardiac factors or muscle factors. This is a great talk and reflects a long-time discussion in Exercise Physiology. LISTEN or WATCH NOW!
