Metabolic Analysis and CPET Testing

Jeff Cournoyer, MHS, ATC, Manager of the Clinical and Research Physiology Labs at the Institute for Neuro-Immune Medicine, shares his presentation on metabolism and its connection to Cardiopulmonary Exercise Testing (CPET). He walks through how he applies the physiological background of his patients to guide more informed decisions about their exercise routines. Jeff also discusses the fundamentals of metabolism and adenosine triphosphate (ATP), explains why evaluating oxidative phosphorylation along with aerobic and anaerobic glycolysis is essential, and outlines how healthy individuals and those with chronic illness respond differently to an exercise challenge as they work to determine their metabolic efficiency. Key points: 00:01 Introduction 00:51 How is Adenosine triphosphate (ATP) produced 02:40 Aerobic metabolism and the mitochondria 03:47 Efficiency of producing ATP in the mitochondria 05:00 ATP production in anaerobic glycolysis 07:25 A “healthy” response to an exercise challenge 09:26 The 2 zones during exercise challenge 11:35 What does the respiratory exchange ratio imply? 12:36 CPET Testing for low intensity exercise 13:22 Metabolic profiles for people with chronic illness 15:12 Utilizing subjective exertional scale 16:28 Exercise challenge for metabolic efficiency 18:03 Using offensively low-intensity exercises Jeff Cournoyer, MHS, ATC is the Manager of Clinical and Research Physiology Labs at the Institute for Neuro-Immune Medicine. With a background in athletic training and a specialization in metabolism and autonomic balance, Jeff collaborates with clinical and research teams at Nova Southeastern University and the Miami Veterans Affairs Health Center. He focuses on treating conditions like Myalgic Encephalomyelitis (ME/CFS), Gulf War Illness (GWI), and Post-COVID Sequelae ("Long-COVID"). Jeff's expertise lies in analyzing human body movement and function to help patients improve their physiological profiles and recover functional capacities. Prior to joining INIM, he worked with professional sports teams like the New England Patriots and the Miami Dolphins.
