Here's a podcast I recently did for Flo's Faster Podcast.
Lots of fun stuff.
Cheers,
Jim

Ooooh...thanks for the "heads up". I can't wait to listen!

Thanks Jim,

I think if people listen they will find the definitions or your explanations of certain terms at the start quite helpful, this lead really well into the rest of the podcast. For example “muscle shortening velocity” which I know you have explained but may not be specifically understood vs the relationship between force/velocity or the force/velocity curve which most people understand through strength training or other sports.

On a side note have you studied, intend to study or know of studies which look at sub maximal efficiency or effectiveness out of the saddle? Say like the variability between world tour cyclists (or the rest of us) while on a long grind, think the differences between Pantani, Ulrich, Froome etc.

Nice work to both you and Chris.

Thanks for an informative podcast. I took away several nuggets.

Hi Maruice:
Thanks and glad you liked it.
The only study I'm aware of on efficiency for out of the saddle cycling is Ryschon and Stray-Gunderson 91. https://europepmc.org/article/med/1956270 There may have been others since then, I just haven't looked.
As you'll see, they reported that oxygen uptake went up by 3.4 mL/min/kg or 0.23 L/min for standing which is the equivalent of about 17watts. And that doesn't include the additional cost of increased aerodynamic drag. Best to stay in the seat if you've got the gears for it.
Cheers,
Jim
