How to Improve Your Second Threshold and Race Pace! | #65 ft. Aaron Geiser

Critical Oxygen

Show Notes

In this episode of the Critical Oxygen Podcast, Coach Aaron Geiser and I discuss the specific phase of training and how to incorporate threshold work. We emphasize that the approach to threshold training may vary depending on the athlete and their goals. We discuss different ratios for threshold work and the importance of individualizing the training based on an athlete's tolerance and recovery. The conversation covers the transition from the base phase to the specific phase and the importance of accumulating time at specific race intensity. We provide examples of threshold workouts for elite level athletes and age group athletes, and discuss the use of ratings of perceived exertion to gauge intensity. We also touch on the differences between threshold work and VO2 max work, and how to progress both types of training during the specific phase.

TAKEAWAYS

1) The transition from the base phase to the race-specific phase involves specific protocols for threshold training and race-specific paced training.

2) The progression of training should be tailored to the individual athlete's response and adaptation, with a focus on fluidity and adaptability.

3) Measuring intensity and progression is crucial for assessing an athlete's response to training and determining the effectiveness of the protocols.

Example Workout Progression:

Initial Part of Specific Phase: Start with 1:1 work-to-rest ratio, gradually increasing intensity and duration.

Mid-Phase: Transition to 4:1 or 5:1 ratios, focusing on maintaining higher intensities.

Final Phase: Shift to sustained efforts at race pace, incorporating longer intervals to simulate race conditions.

Enjoy!

In this episode of the Critical Oxygen podcast, we are doing another SOLO podcast where I discuss my journey from chronic injuries to successfully completing two races after six months of consistent training. I emphasize the importance of understanding training volume (mileage and intensity) as a load marker, the role of key individuals in my recovery, and how blood work has been a game changer for performance. The episode includes a detailed recap of my recent race experiences and the adjustments I made to my training regimen to achieve success. In this conversation, I discuss my training journey leading up to my first race in two years. I share insights on physiological testing, performance assessment, nutrition, recovery strategies, and the importance of managing training volume and intensity. And I emphasize the significance of threshold work in race preparation.

In this episode of the Critical Oxygen Podcast, Dr. Alyssa Olenick and I discuss endurance and hybrid training, focusing how we balance volume and intensity, and the importance of consistency in training. We explore Alyssa's journey from athlete to academic to coach + athlete. Her insights on training load, and the role of cross-training in optimizing performance. We emphasize that more isn't always better and that understanding one's body and training needs is crucial for success in endurance sports. We also discuss the intricacies of hybrid training, discussing what it is, its benefits, the importance of cross-training, and the role of nutrition and sleep in optimizing performance. We clarify the distinction between hybrid and concurrent training, emphasizing the need for a balanced approach to strength and endurance. The discussion also highlights common misconceptions about the interference effect of endurance training on strength gains and the critical role of adequate nutrition and recovery in achieving athletic goals.

In this episode of the Critical Oxygen Podcast, Dr. Eric Harbour, Ph.D. and I discuss the how to breath better during endurance exercise according to science! In this episode we explore the mechanics of breathing, the physiological implications of different breathing patterns, and how these can be optimized for better endurance and performance. The conversation touches on the limitations athletes face regarding their breathing, the psychological aspects of breathing, and the potential for training to improve breathing efficiency and effectiveness. We also discuss the risks associated with over and under breathing, providing insights into how these factors can impact overall health and exercise performance. Our main topic of focus is Eric's research paper called Breath Tools: A Synthesis of Evidence-Based Breathing Strategies to Enhance Human Running - https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2022.813243/full TAKEAWAYS - Breathing patterns significantly influence athletic performance. - Breath control can enhance both physiological and psychological aspects of exercise. - The lung structure is relatively fixed, but breathing function can be improved. - Nasal breathing offers various benefits, including better airway quality. But has limitations at higher exercise intensities. Enjoy! More about Dr. Eric Harbour:Eric has a Ph.D. in sports biomechanics, with a focus on breathing pattern in sport. He is a broadly experienced practitioner with a sports medicine background and has worked in NCAA athletics, alpine ski racing, and New Zealand rugby.

In this episode of the Critical Oxygen podcast, Dave Schell and I discuss the use of Near Infrared Spectroscopy (NIRS) technology, specifically the Moxy Monitor, to enhance endurance training. We discuss the importance of proper placement of the device, how to interpret SMO2 readings, and the practical applications of NIRS in optimizing warmups and training readiness. The conversation emphasizes the need for athletes to understand their physiological responses to training and how to use this data to inform their workouts effectively.
