I realize it's at altitude, but the meet results and the POP list says that's what she jumped 1.95 yesterday at the Air Force Academy meet. Best I can find for her is a 5-11A in HS.

Re: Ada Robinson (BYU) 6-4.75 (1.95) ??!!
She was the Mountain West high jump champion last year. I don't remember her winning height, but I do know she won four Utah state high jump titles in high school. She's also a pretty good volleyball player.
BYU has some good performances so far this indoor season. -

5-11.5 at 1500m altitude. How does one add FIVE inches in PR at this level?Originally posted by DoubleRBarComment

Altitude does not assist the HJ.Comment

Not as much as the sprints, but yes, the lower air resistance and lesser effects of gravity does do a little.Originally posted by unclezadokComment

The elevation, per se, adds nothing to the height. The do not mark the vault, where running speed is important, and the height effects are a multiple of the HJ, so why is the altitude even mentioned?Comment

I would submit that altitude (sic) aids much more in the jumps than 'drafting' in a distance race. (. . . which is to say not a whole lot, unless in a psychological sense. I have sprinted at a 7700' elevation and felt faster, but I suspect it was an expectation fulfillment.)Comment

Re: Ada Robinson (BYU) 6-4.75 (1.95) ??!!
empirical evidence suggests that altitude can very much assist the HJ.
here's the best-ever-mark-for-place stats for the NCAA Championships, in which (A) = mark held in Provo (1387m of altitude:
HIGH JUMP
1. 2.38(A) 7-9¾ Hollis Conway 89
2.34 7-8 Darrin Plab 92
2. 2.31(A) 7-7¼ Del Davis 82
Thomas McCants 85
3. 2.30 7-6½ Rick Noji 90
4. 2.29(A) 7-6 Leo Williams 82
2.28 7-5¾ Ray Doakes 94
5. 2.26(A) 7-5 Jeff Woodard 82
Nick Saunders 85
6. 2.26(A) 7-5 Rod Rudolph 82
Jake Jacoby 85
7. 2.26(A) 7-5 Marshall Broadway 82
Maurice Crumby 85
8. 2.26(A) 7-5 Brian Stanton 82
2.23 7-3¾ Jon Shelton 88
9. 2.23(A) 7-3¾ Thomas Eriksson 82
(A) Chuck Perry 82

coincidence? Yeah, right.Comment

How would it assist it? The runup is not fullspeed. Wind resistance on the way up?Comment

Is it possible the BYU meets were some of the few not held in a raging thunderstorm or a blizzard?

Once you get a deep field and have best marks for place at 2nd or 3rd, it will often go all the way down. Thus, much of this is a 'correlated' observation. Thus, this conclusion comes under the 'small sample properties' and has relatively little 'power'.Originally posted by gh
And wouldn't we expect the top mark to be from Hollis, so the only question there is why that year for his best, which I do not know.
If there were such a systematic effect wouldn't we expect that jumpers would go to altitude like discus throwers go to Salinas, ... whatever those top locales are? Was Mexico City the home of unusual HJ marks? Provo is not particularly high and I would think that actually high places would be much more notable. For instance, the sprint help at Provo is modest compared to Mexico City, I think.Comment

OK, 2nd-place mark happened in '82 (Provo year) and '85 (not). 3rd-place mark happened in '90 (not Provo). I see one other '85 in the chain and no '90s.Originally posted by 26mi235Comment

Re: Ada Robinson (BYU) 6-4.75 (1.95) ??!!
Until 1982, it had not crossed anybody's mind that altitude might help in the high jump. Then that year there were phenomenal results in the high jump at NCAA Nationals at Provo. That is when TFN started to put an "A" next to altitude marks for the high jump. But this makes no sense at all.
Altitude has a negligible effect on high jumping. The effects of altitude on high jump results come through two separate mechanisms: (1) reduced air resistance to running; (2) reduced weight.
The effect of the reduction of air resistance is essentially irrelevant (in the HJ) because the high jumpers are running way below max speed anyway. What limits the speed of a high jumper is the athlete's technique rather than air resistance.
The gravity effect should be around 1 millimeter for the altitude of Mexico City (which is much higher than Provo). (I won't bore you with the calculations.)
Has anybody stopped to think why those amazing results from Provo don't occur over and over again in other altitude meets??
I think something is wrong about those 1982 Provo high jump results. Possible (highly speculative!) problems: Maybe the device used to measure the height of the bar was not calibrated properly; or maybe the apron had a hump near the takeoff area (which happens sometimes to facilitate drainage of a football field); or the officials went by what the standards said instead of measuring the bar at its lowest point --yes, this sounds ridiculous at national NCAA level, but I am scraping the bottom of the barrel looking for possible reasons! I am convinced that something went wrong, I can't say exactly what.Comment

1968 HJ marks were good at altitude, thinking of Echo Summit FOT and then Mexico City OG. At FOT Hartfield's 7'2" is 4th, behind 3 7'3" 's. ( remember this is 1968, pre-Flop except for you-know-who). Then you-know-who jumps an AR 7' 4 1/4" at the OG's.
Did altitude help all this? IMO yes, at least a little bit.Comment
