1. Introduction and Guest Background

Dr. Peter Attia welcomes back Olav Alexander Bu, an endurance coach, exercise scientist, engineer, and physiologist renowned for coaching top triathletes like Christian Blumenfeld and Gustav Iden. Olav emphasizes his engineering background and his decade-long commitment to in-depth, longitudinal studies on elite athletes, focusing heavily on data-driven coaching methods.

[03:38] Olav Alexander Bu: "We embarked on a journey more than 10 years ago where we started to do what I would call extreme in-depth and longitudinal studies on two of the arguably fittest athletes in the whole world."

2. Understanding Performance Metrics

The discussion delves into key performance metrics essential for optimizing endurance:

• Functional Threshold Power (FTP): Originally defined by Andy Coggan, FTP estimates the highest power output an athlete can sustain for approximately one hour. Olav critiques varying protocols and stresses the importance of consistency.

  [06:05] Peter Attia: "The spirit of FTP is it really approximates an energy zone that is more than just an all-out, but clearly less than what you could hold indefinitely."

• Critical Power: A more advanced mathematical approach derived from multiple all-out efforts, distinguishing between sustainable and unsustainable power outputs. Olav prefers this over FTP for its precision.

  [07:32] Olav Alexander Bu: "Critical power is basically where you try to divide something into two zones...trying to figure out what is the power you are capable of staying at for a prolonged time."

• Anaerobic Threshold & Lactate Threshold: These terms often interrelate but differ subtly. The anaerobic threshold typically lies below critical power and indicates the transition from aerobic to anaerobic metabolism. Lactate threshold focuses on lactate concentration changes in the blood, influenced by measurement protocols.

  [12:31] Peter Attia: "Typically anaerobic threshold will sit below the critical power or FTP."

• VO₂ Max: Defined as the maximum oxygen your body can consume in one minute. Olav discusses the variability in testing conditions and the influence of factors like core temperature.

  [23:32] Olav Alexander Bu: "VO2 max is normally defined as the maximum oxygen your body is able to consume over a minute, a full minute."

3. Testing Protocols and Consistency

Both Dr. Attia and Olav emphasize the necessity of standardized testing protocols to obtain reliable metrics. They discuss:

• Warm-Up Routines: Essential for accurate VO₂ max and other measurements. Olav outlines a comprehensive warm-up protocol involving gradual intensity increases and short efforts.

  [38:57] Peter Attia: "How long do you think that should be for a person who's modestly trained?"

  [39:05] Olav Alexander Bu: "I would do a warmup much in the same way I would do a training session... total warmup of 20 minutes."

• Pre-Test Conditions: Consistency in nutrition, hydration, sleep, and training prior to testing ensures that results are comparable over time.

  [35:47] Olav Alexander Bu: "Make sure you are well fueled as if you were going to do an important training session."

4. Application Across Different Sports

The principles of performance metrics are discussed in the context of cycling, running, and swimming:

• Cycling: Power meters make metrics like FTP and critical power straightforward to measure and apply.

  [09:15] Olav Alexander Bu: "Yes, the same concepts still apply in swimming and running."

• Running: Introduction of power meters in insoles allows for similar tracking, though with greater complexity due to weight-bearing and biomechanical differences.

  [70:07] Olav Alexander Bu: "We now have power meters in running as well."

• Swimming: Challenges include drag due to water density. Olav illustrates how technique and efficiency play crucial roles, potentially more so than in other sports.

  [77:17] Peter Attia: "I feel like swimming has the most potential for radical change in performance based on drag avoidance."

5. Nutrition in Endurance Sports

Nutrition's pivotal role in endurance performance is extensively covered:

• Carbohydrate Consumption: Elite athletes today can consume up to 160 grams of carbohydrates per hour during competition, a stark contrast to the 60 grams achievable a century ago.

  [50:07] Peter Attia: "These guys can put down 200 grams per hour... it's twice the standard."

• Buffering Agents: Discusses the use of sodium bicarbonate and other supplements to manage lactate and hydrogen ions, enhancing performance by buffering acid.

  [86:42] Peter Attia: "Can I buffer this? What is the state of buffering agents to reduce and lessen the impact of lactic acidosis?"

• Innovative Supplements: Olav mentions products like Pollen's hydrogel-based carbohydrates and bicarbonate capsules that allow athletes to ingest high concentrations without gastrointestinal distress.

  [111:49] Olav Alexander Bu: "The genius part of it is actually not the carbohydrates itself, it's the packaging mechanism."

6. Buffering Agents and Lactate Management

The conversation explores advanced strategies for managing lactate and associated hydrogen ions:

• Lactate Production vs. Buffering: Clarifies that lactate itself isn't harmful; it's the accompanying hydrogen ions that cause acidosis and muscle fatigue.

  [86:40] Peter Attia: "It's the hydrogen that paralyzes the actin myosin filaments, preventing them from disengaging."

• Innovative Buffering Techniques: Discusses Olav's work with technologies that enhance lactate clearance without compromising muscular efficiency.

  [51:06] Peter Attia: "You have to buffer hydrogen ions... what's the state of buffering agents?"

7. Case Studies: Christian Blumenfeld and Gustav Iden

Olav shares insights from working with top athletes:

• VO₂ Max Optimization: Techniques used to push VO₂ max beyond traditional limits through training and supplementation.

  [45:00] Olav Alexander Bu: "We've exceeded in absolute terms 7.8 liters per minute in oxygen uptake."

• Race Strategy Adjustments: How changes in testing protocols and environmental conditions (e.g., currents in swimming) impacted race outcomes.

  [126:19] Peter Attia: "Christian had to pedal 30% harder for another fifth of the race to stay with the group."

• Performance Enhancements: Use of technology and supplements to maximize efficiency and power output during competitions.

8. Race Experiences: Tokyo Olympics and Paris Ironman

Detailed recounting of athletes' performances under varying conditions:

• Tokyo Olympics: Christian Blumenfeld wins, representing a peak in his readiness and protocol adherence.

  [118:48] Peter Attia: "Both competed in Tokyo Olympics, Christian won."

• Paris Ironman Challenges: Discusses the impact of environmental factors like river currents on performance and how deviations from training protocols can lead to unexpected results.

  [122:21] Peter Attia: "Christian had to pedal 30% harder... he lost around 4 seconds per kilometer on the run."

9. Technology and AI in Performance Optimization

Explores the integration of Artificial Intelligence (AI) in endurance training:

• Data Management: Olav highlights the potential of AI to analyze vast datasets from athlete testing, enabling proactive adjustments and personalized training regimens.

  [129:16] Olav Alexander Bu: "AI and the systems we are building now will have the same implication on purely human performance and training."

• AI Tools: Development of agents and autonomous systems that assist in interpreting complex performance data beyond human capability.

  [127:04] Peter Attia: "AI can extract patterns you might not otherwise be able to via your own statistical analysis."

10. Future Implications and AI Integration

Looking ahead, both speakers envision AI as a transformative tool in sports performance:

• Enhanced Consistency: AI can help maintain training consistency, a critical factor in athlete development.

  [133:42] Olav Alexander Bu: "AI will supercharge us to a completely different level... allowing for much better consistency in training."

• Proactive Training Adjustments: Real-time data analysis and insights enable coaches to make immediate, informed decisions to optimize athlete performance.

  [134:37] Olav Alexander Bu: "Being able to be far more proactive than what I am today... making individual adjustments much more proactively."

11. Conclusion

Dr. Attia and Olav Alexander Bu conclude by emphasizing the intertwined roles of data-driven metrics, advanced nutrition, buffering strategies, and emerging AI technologies in pushing the boundaries of endurance performance. They advocate for a holistic, consistent approach to training that leverages technology without compromising the fundamental aspects of athletic conditioning.

[134:51] Peter Attia: "It's been a fascinating discussion. Thank you again for making the time to swing by on the way to Flagstaff..."
