What Is Durability?

Michele Zanini, PhD, returns to the That Triathlon Show to discuss his latest research on the topic of durability. We also broaden the discussion to include the most up to date research findings on durability from the broader sports science community. 

HIGHLIGHTS AND KEY TOPICS: 

• How long runs and running volume impact durability of running economy
• The difference in physiological deterioration after 120 compared with 90 minutes of running
• Evidence-based interventions and general characteristics for improving durability in runners, cyclists and triathletes
• The most important questions about durability that remain unanswered (for now) by the sports science community
• Michele’s pick of top training and sports and triathlon science trends over the last couple of years

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. 
• The shownotes for today's episode can be found at https://scientifictriathlon.com/673/
