The fastest human on the planet might be a quadrupedal runner at the 2048 Olympics, which may be achieved by shifting up to the rotary gallop and taking longer strides with wide sagittal trunk motion. More generally, investigation of quadrupedal running will not only result in the development of new techniques that allow biomechanists to study locomotion in natural settings but will also reveal the underlying principles of how these runners accomplish their astonishing performances.
The study covers an awful lot more than that. Even the posted excerpt discusses gait analysis and mechanics. Yes it’s a projection, but it’s hardly unfounded.
I stand by my analysis. Statement #1 is fine, if a little bit wierd. Statement #2 doesn’t excuse or ameliorate the total cuckoo pants nonsense of statement #3, though.
If what’s the in study is somehow different – like if the first sentence is “obviously we’re not saying that extrapolating these two particular curves forward suggests the exact year when sagittal trunk motion will manage to overcome millions of years of evolutionary re-optimization away from quadrupedal gait, that would be insane” – then sure. But if that’s true, they should have written the abstract different.
Fair enough!
