• Marinus Peteresen on LT1

  Cycling coach Marinus Petersen returns to revisit bicarbonate supplementation tips and to discuss training around the first lactate threshold (LT1). Petersen shares his views on intensity domains, the importance of LT1, and how he incorporates this concept into his coaching. Bicarb Neutralization: A discussion on whether mixing bicarbonate with acidic substances like jelly or jam neutralizes its effectiveness. Petersen argues that the acidity of the stomach far outweighs any pre-ingestion neutralization. Practicality of Bicarb Use: The challenges of using bicarb in conjunction with a regular work schedule, and tips for timing bicarb intake around workouts. Importance of LT1: Petersen considers LT1 the most critical metric for an athlete due to the significant difference in fatigue levels when training above or below it. Measuring LT1: Lactate testing to accurately determine LT1, using 10-minute stages with 10-watt increments to pinpoint the threshold. Coaching Considerations: A discussion on the challenges of balancing structured training with the enjoyment of riding, allowing flexibility in training as long as the intensity of endurance rides stays below LT1. Sub-LT1 Work: Considerations for aerobic training at very long durations at well below LT1 vs. relatively shorter bouts just below LT1.

• Marinus Petersen on VO2max & Bicarb

  Our guest this week is Marinus Peterson of Kilowatt Coaching. Marinus is an accomplished cyclist and coach with a wealth of knowledge on endurance training. In this episode, we explore the importance his approach to developing VO2max. Oh, and bicarb Jell-O. Highlights include: The Importance of VO2max: VO2max underpins the ceiling of how high you can get your LT1 and FTP/critical power, making it a crucial focus for any training cycle. Anaerobic Capacity and VO2 Max: how anaerobic capacity training can improve the effectiveness of VO2max work. Double Days for VO2max: Double days, featuring high-cadence VO2max intervals, can be a potent tool for maximizing central adaptations and achieving significant fitness improvements - in the right context. High Cadence Training: Training at a higher cadence (20 RPM above natural cadence) when doing VO2max work can lead to greater oxygen consumption and allow for more intervals with less fatigue. Supplementing with Sodium Bicarbonate: Marius's supermarket recipe for a DIY bicarb supplement that doesn't cause gastric distress.Follow Marinus at his Instagram page.

• Cycling Aerodynamic Measurement with Body Rocket

  Body Rocket founder Eric DeGolier joins Andrew and Michael to delve into the complexities of aerodynamic measurement in cycling, challenging the limitations of traditional methods. We explore the inherent flaws in existing technologies that rely on indirect measurements and discuss Body Rocket's approach that directly measures drag force.For more info, follow Body Rocket at their website and on Instagram and read the preprint of the University of Kent study validating the technology.

• Mikael Eriksson: Separating Evidence from Hype in Endurance Sports

  Listeners to the podcast get $50 off the purchase price of the Cool Bottle before DEC 31! Use code COOL2024.Coach and podcaster Mikael Eriksson joins Michael to explore into the world of endurance sports and the constant influx of new training methods, technologies, and nutritional advice. We discuss how to navigate the overwhelming amount of information and separate the useful from everything else. The Impact of Social Media: Social media can be a double-edged sword. While it can be a great source of information, it's also a breeding ground for misinformation and oversimplification. Evaluating Information Sources: Consider the credibility of the source, the depth of the information, and the potential bias. The Importance of Context: A training method that works for one athlete may not work for another. Consider factors like training level, age, and specific goals. The Role of Anecdotal Evidence: While anecdotal evidence can be helpful, it's important to weigh it against evidence-based research. Mikael’s rubric for evaluating utility: A step-by-step guide to making sure the intervention or technology is useful for you.Resources: Mikael's podcast: That Triathlon Show Newsletters: David Lipman's substack, Manuel Sola's substack Instagram: bradstulberg, stevemagness, knowledgeiswatt, ylmsportscience, gudiol (in Swedish) Podcasts: The Physical Performance Show, The Training Science podcast, On Coaching, The Triathlon Hour Books: The Nature of Training, Antifragile, Peak Performance, Science of Running, Factfulness
