Summary

Sprint interval training consists of 4-7 all out efforts of typically 30 seconds, followed by 4 minutes recovery. Jerome Koral has researched this kind of training, and the results of his studies indicate that it may be one of the most under utilised types of training around, that more triathletes should tap into.   IN THIS EPISODE YOU'LL LEARN ABOUT: Specific sprint interval training (SIT) protocols How effective is SIT at improving Time Trial performance, Time-To-Exhaustion, Maximum Aerobic Speed, and so on? How do these results compare to other types of training, like traditional volume-based training or VO2max-type intervals? Injury risk and other risk factors and considerations with SIT The best times of the season to implement SIT   SHOWNOTES: https://scientifictriathlon.com/tts151/   THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com   SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.

The time trial on 3K was shorter by 6%.

0:07.0

So the improvement was 6% on the time trial.

0:10.0

And then the time to exhaustion at 90% of maximum rate speed was 42% longer.

Hey, what's up, everybody, and welcome back to another episode of that triathlon show, the podcast

presented by Scientific Traathlon.com. I'm your host Michael and on today's episode I interview

Dr. Jerome Corral from the University of St. Tietien and he has done a lot of research in a concept called sprint-intral training,

0:57.6

which consists of doing four to seven repetitions of 30-second all-out sprints.

1:04.3

And in Gérons, most recent research, they did it as running back and forth between cones,

1:10.2

so not in a straight line necessarily.

1:13.1

And yeah, the recovery between springs will be four minutes and the benefits are really, really good.

1:19.1

For example, in the research study that Geron's team published in the spring or winter of 2018, they an increase or i should say improvement in their

1:32.3

three thousand meter time trial of six percent and an increase in time to exhaustion of

1:38.1

40 percent at 90 percent of the subject's maximum aerobic speed.

1:46.4

So very interesting stuff that we'll dive into.

1:48.8

But first, big thanks to our sponsors.

Some of you may have seen on my social media, my private one, not the scientific rafl on social media,

2:09.8

that I did a really good race in Kachkais, and I ended up winning my age group in the Ironman 7.3 race that I took part in the other week, and much of that, I think, is because I could

course pacing good training but part of it is also nutrition and hydration and I had a very
