We’re tackling a heavily requested topic today: triathlon training for masters athletes. Is it possible to slow down the natural performance decline through better and smarter training and recovery? Might you even be able to reverse time and hit new peaks later in life? Mikael Eriksson and Jack Hutchens discuss best practices for older athletes based on their coaching experience and the scientific literature.
HIGHLIGHTS AND KEY TOPICS:
- The science of physiological and performance decline with age in swimming, cycling, running and triathlon
- VO2max, strength, muscle mass, fast twitch fibre atrophy, slower recovery, and other factors
- How to tease apart the inevitable decline due to biological processes, and the decline resulting from changing training habits for older triathletes
- The importance of VO2max training, and how to structure it differently for masters athletes
- Strength training as a critical component of triathlon training for masters athletes
- How recovery, nutrition, and sleep needs change with age
- Examples and case studies
- Listener questions
- Practical takeaways
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.
