HISTORY This Week

CHAPTER

Introduction

On this day in 1912, the RMS Titanic set sail on her maiden voyage. The vessel is a microcosm of the gilded world around her - and it has important parallels to our own. We're probably living through something fairly similar for the first time since the early 1900s. It is a warning against the costs of human hubris.

is it actually only 10 I didn't pick up on that it's only 10 minutes total
Speaker 1
yes so I always confuse it it's it's typically a two to three minute warm up a two to three minute cool down with a minute in between or sorry two minutes in between these hard efforts so yes start to finish warm up cool down recovery 10 minutes and we were comparing that against traditional modern intensity continuous sessions that were taking 50 minutes five zero minutes per session so you know a a five-fold lower time commitment overall and those studies extended out to 12 weeks of training the comparisons all
Speaker 2
right so when you do that what do you get similar increases in video
Speaker 1
to max yes but and so when I say yes but in our studies the average improvement in the two groups was 19 percent so roughly 20 percent over 12 weeks or almost a two met increase in b2 max again on average for the two groups obviously within the groups you have significant variability there and again over time we've learned and I think where these studies need to go you can have just because you say two things are not different statistically it doesn't mean they're the same and so you know there's larger scale studies you can do that use these non inferior orated designs where you try to say well what would be a margin of difference that would be meaningful and so I think this is where the field needs to go into some of these more robust designs where you can tease out subtle differences if they're there taking into account power sample size things like that but when we use these small proof of concept studies on average we see very similar improvements in a range of health-related markers I'm gonna let you
