New paper - a theoretical basis for developing running footwear technology.
We propose that running economy (in the context of footwear) is a total effect encompassing a direct mechanical effect and a biomechanically mediated effect.

Very cool study from Ben Southey
Outlines clear methodology for "single case experimental design" for reactive strength development
Such designs could be used much more often in elite sport, n=1 environments
(Open access article)

@ConnickMJ and @GlenLichtwark propose a framework that running economy changes with footwear due to a direct effect of footwear properties and a mediating effect of footwear on ankle and foot biomechanics and the spring-mass system.

ALT Figure 1 — Directed acyclic graph showing the total causal effect of changing footwear properties on running economy for a given runner and a given set of environmental conditions (ie, same surface, gradient, ambient temperature, and time of day). The total effect is measured in laboratory studies. However, the total effect is the sum of 2 distinct pathways. Pathway “a” represents the direct effect of changing footwear properties on the change in energy cost resulting from the change in spring-mass characteristics. The change in energy cost resulting from changes in spring-mass characteristics are proportional and directly related to changes in running economy (pathway “d”). The mediated effect (via changes in ankle and foot biomechanics) is pathways b + c. The mediated effect comprises a direct effect of changing footwear properties on the changes in ankle and foot biomechanics (pathway “b”) and a direct effect of the changes in ankle and foot biomechanics on the changes in energy ...

This is the first of what we hope might be more Target Articles in @JApplBiomech proposing new theoretical frameworks in a research area. Feel free to reach out if you have been rethinking how to address big questions in your movement biomechanics area.

Can you trust heart rate measured on the wrist during exercise?
I did some tests of Polar Vantage V3 and Garmin Forerunner 255.

After four and a half days and 460 miles, Harvey Lewis has won BIG'S #backyardultra with 108 loops. A new WORLD RECORD. He is... the last one standing.

Are you an AT / PT or Physio working with running-based field sport athletes in rehab? You need to know HOW your athletes are generating and controlling speed. We provide the data YOU NEED using the equipment your team already has. speedsig.com/
Great analysis of Assefa's Berlin marathon record by @jgault13. Including possible explanations.
I make it a 2.75% improvement on her previous best time and a 1.63% improvement on the previous WR.

"89% of international U17/U18 athletes never reach that level as seniors, and 83% of international-class seniors weren't U17/U18 internationals"
A good reminder that athletes whose talent seemingly emerges in their 20s are the rule, not the exception.

📢NEW PAPER!
Where @davidthewid, @sarahbmyers & I unpack what Open Source AI even is.
We find that the terms ‘open’ & ‘open source’ are often more marketing than technical descriptor, and that even the most 'open' systems don't alone democratize AI 1/

Put another way...
When your typical age-grouper is cruising along at 140bpm on their "easy" sessions they're burning through the same amount of glycogen as your typical elite on a threshold session!
Is it any wonder you have a hard time handling the volume?

I take a stab at weighing the arguments for why runners seem so fast these days: shoes, pacing, pandemic training, Norwegian thresholds, etc.
I also crunch some data to see if runners really are notably faster - and the jump is smaller than I expected.
