Threshold training: pros and cons

Sebastian Sitko is a cycling and triathlon coach, and a sports scientist. His active involvement in coaching both amateur and professional athletes, as well in conducting and evaluating research means today’s episode is a perfect opportunity to discuss how to approach the integration of science and practice in cycling, triathlon, and other endurance sports. 

HIGHLIGHTS AND KEY TOPICS: 

• The most impactful sports science on Sebastian’s training and coaching practice
• Periodisation - science and practice. 
• How to implement block periodisation in your training program. 
• Sebastian’s approach to ultra-endurance training, with an extremely high proportion of low-intensity training
• Threshold training - science and practice
• Why Sebastian mainly prefers other intensities than threshold training in his coaching
• The myth of “active recovery” 
• What are the limitations of sports science, and applying it in training programs? 
• What are some common misinterpretations of scientific evidence by athletes and coaches? 

DETAILED EPISODE SHOWNOTES: 

• We have detailed shownotes for all of our episodes. The shownotes are basically the podcast episode in written form, that you can read in 5-10 minutes. They are not transcriptions, but they are also not just surface-level overviews. They provide detailed insights and timestamps for each episode, and are great especially for later review, after you've already listened to an episode.
