Oct 16 2024 58 mins  
In this episode of the Critical Oxygen Podcast, Coach Aaron Geiser and I discuss time management for endurance athletes. We discuss the common inefficiencies athletes face, the importance of scheduling workouts, and how to set boundaries to prioritize training. We discuss how athletes can evaluate their daily priorities and communicate effectively with their coaches to optimize the

Be Healthier and Perform Better with Metabolic and Physiological Flexibility | #79 ft. Mike T. Nelson

Oct 09 2024 108 mins  
In this episode of the Critical Oxygen podcast, Dr. Mike T. Nelson and I discuss metabolic and physiological flexibility, and explore their significance in human performance and health. We discuss the importance of being able to switch between carbohydrate and fat metabolism, the role of exercise in enhancing metabolic flexibility, and the implications of research findings on varia

Maximize Your Mitochondria for Better Endurance Performance! | #78 - Fast Phys 23 ft. Dave Schell

Oct 02 2024 25 mins  
In this of Fast Physiology on the Critical Oxygen Podcast, Dave Schell and I discuss mitochondrial respiration and its importance for endurance training and performance. We discuss the common misconceptions surrounding fatmax and VO2max, especially as it pertains to mitochondrial respiration. We also highlight the significance of both high-intensity and low-intensity training, advo

The Best Technology for Endurance Training and Performance?! | #77 ft. Aaron Geiser

Sep 25 2024 77 mins  
In this episode of the Critical Oxygen Podcast, Aaron Geiser from EndureIQ and I discuss the technology we use for training and how it informs our workouts. We emphasize the importance of rotating shoes to stimulate different muscles and prevent overuse injuries. We also discuss the use of heart rate monitors, core body temperature monitors, and NIRS devices like Moxy Monitor to ga

The Physiology of Lactate and Maximal Glycolytic Rate (VLaMax) | #76 ft. Benedikt Meixner

Sep 18 2024 91 mins  
In this episode of the Critical Oxygen podcast, Benedict Meixner and I discuss, maximal glycolytic rate (VLaMax) and how its measured through a 15-second all-out sprint test. VLaMax refers to the maximal rate of glycolysis or maximal glycolytic rate, which is measured through the end product of glycolysis, lactate. The standard VLA Max protocol involves a 10-minute warm-up at 1.5

Understanding the Stress Response to Exercise | #75 - Fast Phys 21 ft. Dave Schell

Sep 11 2024 22 mins  
In this of Fast Physiology on the Critical Oxygen Podcast, Dave Schell and I discuss the stress response of our bodies to exercise and the release of stress hormones like catecholamines. We explain that exercise is a massive stress on the body, causing physiological changes such as increased heart rate and the release of stress hormones. The release of stress hormones helps the bod

Is More Carbohydrate ALWAYS Better for Endurance Performance?! | #74 ft. Aaron Geiser

Sep 04 2024 61 mins  
In this episode of the Critical Oxygen Podcast, Coach Aaron Geiser and I discuss the importance of individualized nutrition for endurance athletes. We emphasize the need to tailor nutrition plans to each athlete's specific needs and goals including individualized fueling in race. Aaron introduces the the right fuel at the right time motto and how EndureIQ uses it to optimize pe
