I removed the jumpsoles advertisment

I propose that this page be merged with Vertical Leap. --Raelifin 22:17, 23 June 2006 (UTC)[reply]

What is an average vertical jump height for a 24 year old male?

-The average vert of the nba is 28, average male 24 yr old would be around 20"

"More efficient?"

"A second, more efficient and correct method is to used an infrared laser placed at ground level. When an athlete jumps and breaks the plane of the laser with their hand, the height at which this occurs is measure."

How is this more efficient and correct?

Surely calibrating lasers etc is less efficient and as for being "correct" that just doesn't make sense....

Surely the pressure pad timing and a bit of school boy mechanics is just as good...

This paragraph is unclear. Please change.

Studies have shown that the majority of force generated during a vertical jump is generated by these muscles, and most importantly the quadriceps which are not part of the p-chain but rather the Anterior Chain

Velocity upon leaving ground?

Thanks for generating this article.

How does the range of motion of the legs to move the center of gravity affect the initial velocity of the jumper at the moment his or her feet leave the ground? — Preceding unsigned comment added by 71.191.235.26 (talk) 14:52, 6 October 2011 (UTC)[reply]

Records?

I'm a bit surprised that neither the article nor the Talk page mention any records. Is the official record holder Kadour Ziani (with 5'11", 56" Vertical Jump)? Is the unofficial record by Yan Zhi Cheng (97", he used two legs to set off which made it unofficial, but apparently it was mentioned in the Guinness Book of Records of 1989)? --82.170.113.123 (talk) 14:00, 19 March 2013 (UTC)[reply]

By the way, footage of Kadour Ziani's record is available here. Very different from what is described in the article, I think. I didn't read the whole thing, but he's running and then lifts up one leg very high. Still impressive though. --82.170.113.123 (talk) 14:08, 19 March 2013 (UTC)[reply]

"Two types"

This is misleading as there are two sub-types within standing jumps, with an important distinction, and who knows how many in running jumps. For standing jumps you may either start from the crouched position (a squat jump) or start tall, crouch down and and then jump from the resulting squat (a countermovement jump;). This dynamism tends to produce higher results due to the muscles already being called into action for the deceleration into squat.

Contradictory/confusing statements

The numbers in the "vertical jump as an assessment" and "vertical jump norms" sections flat-out contradict one another. It is possible that the values may be measured differently (e.g. centre of mass vs. height cleared) but this is not properly explained in the article. Here is a secondary source which at least backs the (currently unattributed) 25cm claim somewhat: Rosetta: could-you-jump-onto-a-comet. 197.82.193.46 (talk) 17:04, 11 September 2014 (UTC)[reply]

"Outstanding"

I've noticed that the section on having a 40 in+ vertical as being outstanding is unsourced. It has been that way for a while so I'm removing it. Anecdotally, from looking at a variety of official NFL players it would probably be true given how the top verticals are in the 34-38 inch range. However, without any proper sources we shouldn't speculate. NeoStalinist (talk) 00:58, 11 November 2016 (UTC)[reply]
