In this episode, Olav returns to dive deeper into his groundbreaking work as an endurance coach, exercise scientist, engineer, and physiologist. The discussion explores his data-driven approach to coaching, unpacking key performance metrics like functional threshold power, VO2 max, and lactate threshold, while emphasizing the importance of consistent testing protocols. Olav shares insights on how training methodologies differ across sports, the impact of nutrition on endurance performance, and the evolving strategies for carbohydrate metabolism in fueling athletes for races. Olav concludes with a discussion on the use of artificial intelligence for optimizing training insights and performance.</p> <p><strong>We discuss:</strong></p> <ul type="disc"> <li>Olav's unique, engineering-driven approach to endurance coaching [2:45];</li> <li>Definitions and applications of key performance metrics: FTP, power, anaerobic threshold, and lactate threshold [4:45];</li> <li>Lactate threshold: factors affecting lactate threshold, testing protocols, and how elite athletes' efficiency affects their performance and lactate profiles [14:15]</li> <li>VO2 max: definition, testing, factors affecting its accuracy, and methods for optimizing oxygen utilization in elite athletes [22:15];</li> <li>Testing VO2 max: common mistakes and key factors to consider—preparation, warm-up, timing, and more [34:00];</li> <li>VO2 max testing continued: measuring instruments, testing protocols, and advanced insights gained from elite athletes [41:45];</li> <li>The influence of supplements like beetroot concentrate and adaptogens on VO2 max and performance [49:45];</li> <li>How respiratory quotient (RQ) reflects metabolic shifts during exercise, the challenges in measuring and interpreting RQ in elite athletes, and the physiological adaptations needed for prolonged endurance events [53:30];</li> <li>Triathlon training: the challenge of maintaining elite performance across triathlon distances, metabolic efficiency, and swimming challenges [1:03:15];</li> <li>How reducing drag in swimming could revolutionize performance and the role of biofeedback tools in optimizing efficiency across various endurance sports [1:07:00];</li> <li>How endurance athletes prioritize effort regulation using RPE, heart rate, and power output, and the role of lactate in cardiac and athletic efficiency [1:20:00];</li> <li>Lactate's role as a fuel, buffering methods to combat lactic acidosis, and the variability in athlete response to bicarbonate supplementation [1:25:45];</li> <li>The physiological mechanisms behind differences in performance between two elite athletes: lactate transport, cardiovascular efficiency, and compensatory systems [1:33:00];</li> <li>Comparing interventions like acetaminophen to enhance performance in high-heat conditions versus natural adaptations to heat [1:37:15];</li> <li>Advancements in nutrition science, changes in cyclist body composition, and the impact of fueling strategies on athletic performance and growth [1:39:30];</li> <li>Optimizing endurance performance with utilization of carbohydrates, and the potential role of ketones [1:48:00];</li> <li>Insights gained from elite performers in the 2020 and 2024 Olympics [1:58:30];</li> <li>The use of artificial intelligence to optimizing training insights and performance [2:06:30]; and</li> <li>More.</li> </ul> <p>Connect With Peter on <a href="https://twitter.com/PeterAttiaMD">Twitter</a>, <a href="https://www.instagram.com/peterattiamd/">Instagram</a>, <a href="https://www.facebook.com/peterattiamd/">Facebook</a> and <a href="https://www.youtube.com/channel/UC8kGsMa0LygSX9nkBcBH1Sg">YouTube</a></p>
Actionable Insights
Employ AI systems in coaching and training to enhance precision, improve consistency, and optimize training adaptations, as not utilizing AI may lead to a significant performance deficiency in the future.
2. Proactive Individualized Training with AI
Leverage AI to analyze collected data and make proactive, individualized adjustments to training programs, which can significantly improve performance for both elite athletes and amateurs.
3. Train Gut for High Carb Intake
Train your gut to tolerate and utilize high carbohydrate intake during endurance events, aiming for up to 160 grams per hour, as this is crucial for sustained performance.
4. High Volume Carb Drink Intake
To support high carbohydrate intake during endurance events, consume 1.4 to over 2 liters of a concentrated carbohydrate drink mix per hour.
5. Use Hydrogel Bicarbonate for Buffering
Mix bicarbonate tablets into a hydrogel solution (e.g., Morten product) to efficiently deliver it to the intestine, bypassing gastric issues and potentially enhancing buffering capacity.
6. Use Hydrogel Gels for Carb Intake
When consuming high amounts of carbohydrates, use hydrogel-based products that encapsulate sugar, as this reduces the perception of sweetness and can improve tolerability during long events.
7. Pure Glucose/Fructose for Fuel
During endurance races, prioritize pure glucose and fructose as carbohydrate sources, avoiding fat and protein, to maximize oxygen availability for pure propulsion.
8. Train All Physiological Capacities
Recognize that most physiological capacities, including gut tolerance for high carbohydrate intake, are extremely trainable and can be developed over time.
When testing performance metrics like FTP or VO2 max, consistently use the same protocol each time to ensure accurate and comparable data for tracking changes.
10. Standardize VO2 Max Pre-Test
For accurate VO2 max testing, standardize your pre-test routine by eating the same way (well-fueled with carbohydrates), ensuring good hydration, and getting proper sleep.
11. Structured VO2 Max Warm-up
Implement a structured 20-minute warm-up before a VO2 max test, including easy, moderate, threshold-feel, and short V2Max efforts, to optimize test results.
12. Consistent Test Timing
Conduct VO2 max tests at a consistent time of day to account for circadian rhythm fluctuations and ensure comparable results over time.
13. Tailor Pre-Test Training Load
Use personal experience to determine the optimal training load the day before a VO2 max test, avoiding hard exercise if it causes soreness, but mimicking pre-competition routines if well-trained.
14. Standardize Fat Oxidation Tests
Separate fat oxidation testing from VO2 max tests by at least a day, performing them fasted in the morning as a sub-maximal effort to accurately measure maximum fat oxidation.
15. Utilize Running Power Meters
Consider using commercially available running power meters (e.g., Stride) to quantify metabolic power, as they provide valuable training data that correlates with oxygen consumption.
16. Prioritize RPE in Long Races
In long endurance races like Ironman, listen to your body and prioritize Rate of Perceived Exertion (RPE) over strict numerical targets (power, heart rate), especially on ‘hero days’.
17. Cost-Effective Carb Sources
For carbohydrate intake up to 60 grams per hour, use cost-effective simple carbohydrate sources like orange juice or honey mixed with water, and train your gut to tolerate them.
18. VO2 Max Test Breathing Hack
To artificially boost VO2 max numbers for a test (e.g., for a bet, not fitness), practice restricting breathing for a short time near your all-out effort to create an oxygen debt.
