ACTUAL LONG JUMP MARKS - Powell 8.98m

[parkerrclay]

I just got through reading 6th IAAF Statistics Handbook (Athens 1997).

The book states: (Tokyo 1991)
"Scientific analysis showed that the winner (Powell) actually leapt 8.98m including a toe-to-plasticine distance measured at 3 cm."

It also states, re. 1987 World Champs it says, "According to the IAF Scientific Report of the championship, Lewis actually cleared 8.84m on his first jump. The distance includes 2 centimeters “lost” on the takeoff board and another 15 in the sand. His other “effective” distances were 8.68, 8.67, 8.64 and 8.76."

Does anyone out there have any more "effective" or "actual" distances for Lewis, Powell or any other great leapers??

what does this mean about losing 15cm in the sand ?

if they mean he fell back or scraped his hand, then they are pretty much guessing on the distance, whereas toe to sand can be worked out to a very accurate level

I'm sure it was an estimate based on the footage analysis or whatever. But there's little doubt that he did lose some distance on his landing.

All this supposed record keeping is quite spurious. Jumps are measured from edge of board to nearest break in sand.... Period !!! And end of discussion as to distance of any particular jump.

take-off to sand is obviously very important - it tells the athlete what they could do on their "perfect" jump - if a guy jumps 8.50, but was 10cm behind the board, he knows he's capable of 8.60 on his "perfect" jump

this is all self-evidentary & i'm bit upset that it even needs to be spelled out aloud

i tried some analysis using projectile analysis, as a proxy for "optimum technique":

it shows that from some of King's jumps, if he'd been able to harness all that incredible take-off speed,he wouda jumped easily over 9m & yes, that rome jump of 8.67 had potential to be a 30ft jump

it's just that at such incredible speeds, it's almost impossible to keep the technique together, but not going at least 9m in some of those jumps was almost criminal !!!

I agree completely eldrick but that's for the athlete's use, none other... to have "statistics" on these phantom jumps printed in a book is ridiculous. That was my only point.

it's also pointless having relay splits since there is a a 10m exchange zone in which transfers occur, but that doesn't stop discussion about splits being amongst the most popular of all topics !

people luv stats & if i for one had been the King back in the '80s & felt deflated that i hadn't broken the wr, if someone had come up to me & said:

"King, we analysed your jumps & theoretically, if you can harness optimum technique to your speed & angle, the physics tells us you should jump over 30 feet"

now, i would suggest that with any reasonably intelligent guy, this would have been some of the most inspiring news that you could ever hope to hear !

didnt Lewis have a 9m plus marginal foul once???
