The crural indexThe skelic index describes leg length in relation to torso length and is defined as the derived total leg length (stature minus sitting height) divided by sitting height. These ratios are depicted in Figure 2.
Crural index & long/high jumping:
Table 1. Here we show that while the computed somatotype components describe physique, the crural index (Davenport, 1933) represents an additional discriminant in describing physique variation across our adult sample. A dominant crural index in classes 2 and 4 illustrates the importance of relative limb length in athletes trained for endurance and strength. A smaller crural index may be advantageous for general agility, whereas a higher value may determine mechanically advantageous take-off technique in long-jump and high-jump events (Alexander, 1990) and in basketball, in tandem with development of commensurate muscle power to maximise femoral leverage Ackland et al., 1997).
Skeletal ratios
Significant differences in skeletal ratios are found between different types of
athletes even when differences in absolute body size are taken into account.
Marathoners tend to have a high skelic index (ratio of total leg length to
sitting height), that is, relatively longer legs. Distance runners also have a
higher crural index (ratio of lower leg length to upper leg length). Longer legs
reduce stride rate, and relatively shorter thighs mean that the resistance arm
on the upper leg is shorter. The muscle mass of the thigh is moved closer to
the axis of rotation of the leg, reducing the energy cost of locomotion.

Anthropometric modelling of the human vertical jump
"A study of the proportions of animals of different species indicates that the
fast runners and jumpers are those that have long distal segments, such as
the horse, kangaroo, and the cat. The thigh segment of these animals is
short, ending before the segment leaves the pelvis or flank area The leg
segment is longer than the thigh; the foot segment is the longest, and the
toes are also quite long The animals described as the best jumpers have a
leg considerably longer than the thigh segment and therefore a large crural
index."
"Ross et al. (1982b) compared female high jumpers from the 1976 Montreal Olympic
Games to a group of Canadian reference females, and found that the high jumpers were
proportionally short in sitting height (in other words, proportionally long in the lower
extremities), and that the tibial length was also proportionally long. This supports the
notion that there is an advantage to having long lower extremities and a larger crural index
for jumping.

I found some other stuff, but I really want to find that high jump study.
Very good article: Physical Structure of Olympic Athletes
Some general differences:
Nice table of differences:
Bigger calfs in 400m sprinters:
High jumpers vs sprinters:
Nice table comparing white/black sprinters vs long distance runners:
Nice table comparing white/black sprinters vs basketball players:
Nice table comparing men & women:
Nice table comparing black & white athletes:
Weightlifters & Throwers:
arm leg & leg length of a bunch of events, white vs black:
obvious, but interesting:

Crazy Weird Analysis & Stuff :) / Re: The Squat Thread
« on: March 19, 2010, 06:42:27 am »That is a very interesting topic , great work again Andrew!
Ive been in this dilemma many times...
I feel much better and stable on the half squat , and i can add weights linearly there.
In deep squats i seem to struggle in the hole , and i cant add weight linearly, it takes about 3 sessions with the same weight until i feel i can really add.
But everyone insisted deep is better so i kept trying to improve deep.
Many times i ended up doing naturally what you mentioned above... going very deep in warmups and gradually decreasing depth as the bar got heavier.
Ya that's why eventually I started half-squatting after seeing eddie's gains, but making sure I hit the walking lunges/stepups very hard. I had to stop doing stepups because my glutes were getting too big, it would aggravate an issue I have in my sacral spine.

Now what about leg leverages? i have no damn clue how to evaluate those, but im sure you do:
Are there any formulas , or ratio ranges or anything?
My height barefoot is ~72''
Height from toes to middle of knee = ~21,5'' ( 55% of leg height , 29% of total height ).
Height from middle of knee to hip joint = ~18'' ( 45% of leg height , 25% of total height ).
Obviously leg height = ~39,5'' ( 54% of total height. )
Hoping this ( actually not this , your reply to this, LOL ) might help other people too evaluating their leverages.
I actually had data on a few athletes, but I can't find it. I also can't find some high jumper study comparing femur length to tibia length. I am full of fail currently.
I will post my measurements tomorrow.
peace man

ya possibly due to flexibility... warm up by front squatting lightly, or unracking the bar in a front squat position to warm up the wrists/forearms/triceps.

Baseball / Some NCAA Baseball performance stats
« on: March 19, 2010, 05:11:42 am »
taken from: http://www.ncsasports.org/recruiting-tools/baseball/baseball-recruiting-guidelines
Division I: Division II:
For some colleges, especially those in the southern states and out on the West Coast, DII Baseball is an extension of DI. There are very few differences between the typical West Coast or southern DII player and the average DI player. For the DII schools up north, the athletes may be a notch below the average DI and perhaps a little less polished. They may not throw as hard, play for the top high schools programs, or possess at least 4 of the 5 measurable tools. This is not always the case, as there are some very solid DII Baseball Programs up north. However, it is no secret that overall, the better baseball schools are those located in warmer climates.
The Minimum Requirements by position are as follows:
Right Handed Pitchers:
-Height: 6'0' (Preferably taller)
-Weight: 175 lbs.
-Averaging about 1K per inning pitched
-ERA below 3.00
-Velocity: 85 MPH
Left Handed Pitchers:
-Height: 5'10' (Preferably taller)
-Weight: 165 lbs.
-Averaging about 1K per inning pitched
-ERA at 3.00 or below
-Velocity: 83 MPH
Outfielders:
-Height: 5'10"
-Weight: 165 lbs.
-60 Yard Dash: 6.8 or below
-Velocity from the OF: 82-86 MPH
Middle Infielders:
-Height: 5'9"
-Weight: 165 lbs.
-60 Yard Dash: 6.9 or below
-Velocity from the INF: Low 80's MPH from SS
Catchers:
-Height: 5'10"
-Weight: 180 lbs.
-Pop Time: 2.0 or below
Corner Infielders:
-Height: 6'0"
-Weight: 180 lbs.
-Power Numbers: 4+ HR, 20+ RBI
Much can be determined on film. It is very difficult to measure defensive abilities on paper. Fielding percentage cannot be used as an accurate statistic because it is difficult to calculate and it can be easily manipulated. Most Division II players have received several accolades, such as All-Conference or All-Area.

3/18/2010
very sore in my left calf/erectors.
bunch of forward sprints/back pedal sprints
got bored, jogged like ~1.5 miles to a basketball court
jumps in track flats from 1-2 steps:
- 10'3 touch LR
- 10'1 touch RL
- happy with these, didn't side plant since i was in flats
~1.5 mile run back home:
- this was very good, pushed the pace
- must be around 6 minute something mile..
- takes me a little bit to reach steady state, but once i did, my pace was good
- calfs start off very strong but then weaken up a bit, all in all very good though considering the soreness
- edit: i sprinted the last 100 yards or so very fast.. havn't been able to sprint it that faster after jogging since now.. so that felt good.
ISOM 2 rotations only - recovery:
horizontal pullup hold:
- 2 x ~30-40 seconds
incline pushup hold on handles:
- 2 x ~40 seconds
squat hold:
- actively pulling knees back, activating hamstrings
- 2 x ~40 seconds
single leg squat variation hold:
- 2 x ~30 seconds
standing calf raise hold:
- 2 x ~40 second hold
done.

here's a vid of a female high school volleyball player. I don't know why they have her squatting so wide, she looks crazy unstable like that i would have her going substantially less wide and making sure she pushed those knees out
ya, especially for females who have wide hips and alot of knee valgus to begin with.. plus the way she's looking up, it's going to cause way too much of an arch in her back.

« on: March 19, 2010, 01:38:34 am »it looked to me like when he brought his hips forward, they should be coming up a little higher than they are, like his hip flexors are a little tight, i would think the steps would be a little longer
after watching it again though not sure
well you could make that case possibly, if this was a 60m+ sprint.. ie 100m sprint. there he would have to focus on bringing the knees up & trying to maintain top speed, but not for a 40.
