How can the observation that the cheetah can artificially "lengthen" its limbs by flexion / extension of the spine be conveyed to human running? That only works when sprinters would suddenly decide to use their arms to run as well.

because humans run on all fours, or something......................................................... 

perhaps we should look at an animal which locomotes (lmao) in the standing position.. such a a kangaroo.. brb sprinting bilaterally.

brb sprinting bilaterally.

That's why for me - jumping off two has never been natural. When you walk/run you don't bounce on two feet. Jumping is just an exaggerated, longer "step" on one leg to me. And we're built to move unilaterally.

That's why for me- jumping off one leg has never been natural. When you jump/squat you don't bounce on one foot. Jumping is just an exaggerated, longer "jump squat" on two feet to me. And we're built to jump bilaterally.




(I actually jump off 1 foot as well, but jumping off 2 never felt natural to you because you are uncoordinated, not because it's a weird movement).

uhhhhhhh.. we're built to move exactly how we move.. bilateral jumping is very natural.

FUCKING COME ON PEOPLE (raptor).

One bilateral jump takes about 10 times the effort I need to jump off one leg. Totally ineffective, in terms of everything else than force (slower speeds, worse leverages, harder on joints (yes, the one leg jump is smooth and without that much joint shock, in the bilateral jump there's a HUGE perpendicular to the ground (more or less) BRUTAL SHOCK in a successful DLVJ), more effort needed and so on and so forth).

You people need to start bouncing around instead of walking and running if two footed stuff is such a good and efficient movement.

You guys failed to understand what I was getting at.

Humans have the ability to decompress there spines too.

What happens during decompression?.

Go back to Reply #18.

where's the "spinal decompression", i can't find it.

super slow motion:

How do you not see bolt on all fours that whole race, EXACTLY like the cheetah and horse in those clips? its plain as day blu.

+1 lol.  

You don't have to get on all fours though.

Obviously your not looking out for the same amount of spinal decompression as the cheetah.

It's far less in humans.


A good example of spinal decompression, Asafa at 1:22.

Bolt's is even more evident as his spine is more flexible, but you need to slow down the video's to the right speed & get the right angle.

can please provide screenshots blu?

I jump off both 1 and 2 feet pretty darn good. Both feel completely natural. Maybe I'm just uber-coordinated.

that isn't natural blu, we are unilateral creatures blu.
