Thats pretty cool stuff.
Makes sense. I like lifting weights. I remember taking a class in HS and it was about people's proportions, 2/3s of the body was to the hip, and 1/3 obviously was for the rest of the body(hip to top of the head). That was supposed to be the 'ideal' figure. Related to women's waist-to-hip ratio, if you know what that is.
But yeah, people with longer legs, IMO, usually have longer achilles as well(just from having longer legs), which afaik makes someone more predisposed to being a natural jumper.
When I look at the Sittting vs Standing measurements, all it is is biomechanics. Lower SHR = longer femurs, right?
So for me, when I squat, my butt doesn't have to deviate from the body's midline as much.
For the lower SHR guys as well. Most people train their strengths too. Human nature, do whats easier(relatively in this instance). Squatting wasn't for that 'type' but like you said they were more 'natural' jumpers.
ya definitely..
as for lower SHR equalling longer femurs, that could be the case, or actually longer tibia's (lower leg). Based on the 2nd chart listed here:
http://www.adarq.org/forum/index.php?topic=547.msg3447#msg3447 400m runners has longer tibia's than sprinters & high jumpers had longer thigh lengths (femur). So ya, regardless, SHR is longer legs in general, could be due to femur or tibia.
I think the key beyond just longer legs, is "longer legs in relation to upper body (torso + head)". That is where we're going to see the longer tendons. SHR seems like it can be pretty valuable in this regard.
Those natural limb leverages definitely mold who we are, because as kids, we find certain activities more fun than others, which usually has something to do with our natural leverages & natural physiology. Their are of course outliers but, they are outliers nonetheless. If we took an accurate survey of all the vert-broz on the forums, or basketballers in general, im sure you'd rarely ever find people over 51.
A higher SHR might be better correlated with standing vert though, ie, i've seen a study with asians having on average higher standing verts than blacks and whites. These leverages would also lend themselves more to sports like olympic weightlifting and gymnastics, both of which the "chinese" do very well in.
peace man
