Summary

There's a lot of confusion around the concept of thresholds in endurance sports and triathlon. In this episode you'll get a clear and concise explanation that will help you understand thresholds once and for all. IN THIS EPISODE YOU'LL LEARN ABOUT: What the terms aerobic threshold, anaerobic threshold, lactate threshold, ventilatory threshold, functional threshold, and other related terms really mean How the thresholds relate to your training How the thresholds relate to your racing Why it is important to understand the thresholds to train optimally for your event-specific limiters LISTENER QUESTIONS: If you have questions that you want me to answer on the show or off the show (in an email), send me your question via email or Twitter (contact information below).

That Triathlon Show, episode 71.

Hey, what's up, everybody, and welcome back to another episode of That Triathlon Show, the podcast presented by Scientific Triathlon.com.

0:26.7

I'm your host, Michael, and on today's episode, we'll go right down the rabbit hole of explaining what all these different threshold terms that you see and here thrown around really mean.

0:38.8

So what we'll do in this episode is to explain what terms like aerobic threshold,

0:44.6

anaerobic threshold, lactate threshold, functional threshold,

0:48.0

plus maybe some other related terms like onset of blood, lactate accumulation,

0:53.0

fat maxone, etc. mean.

0:55.6

And I'll discuss what it means for you and your training and racing because at the end of the day,

1:00.5

you want to get faster and it makes no sense knowing these different concepts,

1:05.4

1:10.4

So we'll cover that as well as usual to make this actionable and applicable to you.

1:16.3

So I'll be back after this main segment also to give you a quick snapshot from a very interesting

study that I just came across on the risk of developing diabetes or impaired glucose

1:25.9

tolerance for endurance athletes compared with a normal

1:30.1

control population and other types of athletes that are not endurance athletes.

1:35.4

So it's really fascinating, but first let's start talking thresholds.

1:43.5

So let's start this discussion with a quick caveat.

1:47.7

I will simplify this discussion quite a bit to make sure that everybody can understand it in layman's terms.

1:54.6

So bear with that if you are an exercise scientist listening to this.

1:59.5

Also, there are several slightly different nuances in

2:02.8

how to define and use the different terms that we will discover and some different concepts.

2:08.5

So in this episode, let's not care too much about the slight differences, but focus on the
