(a) The number of athletes from each country from 1950 to 1989 (the year out-of-competition drug testing started). (b) The number of athletes from 1990 to 2023. (c) The all-time number of athletes (1950–2023).

Curious how cardiac output, leg blood flow, O₂ delivery & O₂ extraction differ between highly-trained females and males in limiting VO₂max?

And impacts of normalizing for muscle mass?

We examined this using thermodilution & blood gas analyses:

I’ll come out of my social media hibernation and share some of what I’ve been up to 🤷‍♂️

I’ve enjoyed integrating lung mechanics 🫁 and CV function🫀. First piece out the IEEM tackles dynamic hyperinflation on measurable LV filling pressures in HFpEF.

Last month, I chatted with @ShalayaKipp about the research published in Royal Society Open Science that modeled Faith Kipyegon’s energy output across multiple pacing strategies and determined she could go as fast as 3:59.37—the exact time Bannister clocked in 1954.

We discuss it here ⤵️

Out now @ExpPhysiol from @ShalayaKipp @jwsenefeld @DrMJoyner: Sex differences in elite track and field performances and inferences about steroid doping 👇

[Alex Hutchinson @sweatscience]

Neat analysis that puts numbers to the idea that pre-1990 steroid use put women's records farther out of reach than men's records.

My daughter is a great source of my motivation. On many occasions when I fall short of coming first, she calls to ask why I never win. I'm really motivated by that. 💝

DM me if you have ones you'd like included. It's currently Canada-centric🇨🇦 , but I'd love to broaden it. And please share.

Our latest work (@SKHunterPhD) reviews the current understanding of sex differences in human performance and highlights underlying physiological mechanisms contributing to these sex differences.

Direct measure of blood flow while running (via thermodilution)! 😲

Amazing work @Mick_Leahy_ et al!

https://t.co/H53wxpjF7E

[Mick Leahy @Mick_Leahy_]

Using femoral venous and transpulmonary thermodilution, we were able to directly measure leg blood flow simultaneously with cardiac output during high-intensity running.

You can see the process here, and in the supplemental materials of our paper

[Shalaya Kipp @ShalayaKipp]

@ptreviewer Thank you 😊

[Shalaya Kipp @ShalayaKipp]

When you think about VO2max, your might imagine those large leg muscles consuming all the oxygen. But what about the respiratory muscles!

Here we look at how much oxygen the respiratory muscles consume during exercise.

@Jordan_Bird_ Fantastic! Thanks for sharing!

[Shalaya Kipp @ShalayaKipp]

Based on our observations, there seems to be an upper limit to the fraction of total oxygen the respiratory muscles consume. The fraction of oxygen the respiratory muscles consumed (VO2RM) seemed to hit a ceiling around 18-19%.

[Shalaya Kipp @ShalayaKipp]

There is plenty more in our paper on respiratory muscle efficiency, sub-maximal workloads, the work of breathing, and energy vs oxygen estimates of cost! 👇

[Shalaya Kipp @ShalayaKipp]

It's possible the higher fraction of VO2RM during peak exercise predispose young females and older individuals to divert more blood flow to respiratory muscles at the expense of other muscles, which could compromising exercise performance.
