In your article about jumping you say 'pole vaulting for distance' is no longer practised However, in the Netherlands this is a very popular sport practised by a fair amount of people. We call this fierljeppen.

Are Elephants the only animal that cannont jump?
If the criteria for jumping is lifting one's body under one's power, then it seems walruses would not be classified as jumpers. There might also be some other water animals that would not classify as jumpers, e.g. jellyfish. The list could be quite long.
- Sponge, sea urchin, coral... I can think of plenty of animals that can't. --DropDeadGorgias (talk) 18:07, September 9, 2005 (UTC)
How about other land mammals that can't jump? Can giraffes jump? Sloths? --Allen 06:21, 18 January 2006 (UTC)
- I'm just going to delete it. There are lots of animals that cannot jump. I'm willing to guess that many land mammals are incapable too. --Burbster 00:31, 1 July 2006 (UTC)
Shouldn't there be a section in this article describing the muscles involved in jumping? David3001 15:39, 11 February 2007 (UTC)
The German dance band Scooter (band) used the definition of Jumping on this Wikipedia page (first alinea) as lyric for their song "The Definition", which is the first song of their latest album Jumping All Over the World. In this song a computer generated female voice reads the definition on this Wikipedia page, supported by a well known piece of classical music.
Ok, I figured I should put this here before I start, but this article is in major need of change. I was planning to make it more generalized, focusing more on how jumping works, it's ecology/purpose, comparative animal studies, etc, and relegating the bulk of the current article to "trivia".

from previous research and knowledge i have always known POWER to be a part of health/skill related fitness, NOT JUMPING. I write not to critiscize, but i do question where this material came from, and the idea of 'jumping' instead of 'power'. can you show some kind of evidence of this? or could anybody see this topic from my point of view? —Preceding unsigned comment added by 220.127.116.11 (talk) 19:34, 9 December 2008 (UTC)
- "Power" is actually the proper metric for a jump, according to the technical definition of power. In a standing jump, the muscles do a certain amount of work (adding energy to the system), resulting in the final kinetic energy of the body (which is proportional to velocity squared). The more work the muscles do, the greater the final speed, thus the shorter the time interval of the jump's propulsive phase. Work divided by time = power. The more power you generate, the greater the jump distance or height will be. Many jumping animals have muscles optimized for power production (as opposed to optimization for force or velocity), as well as adaptations such as elastic elements to increase power output.

- AFAIK, there's only a few, and they pretty much use the same mechanisms as organisms. Mokele (talk) 14:21, 5 July 2009 (UTC)
I only mention this because a quick google search for "jumping robots" indicates (1) widespread research is being done in this area; (2) many existing robots are capable of jumping; and (3) a significant number of jump-capable robots are under development. Since robotic jumping is concerned with the physics of jumping, and in light of the growth and importance of this technology, shouldn't there be at least a mention of this in the Physics section of this article?
- Most of them are pretty simple, though, and have uncontrolled leaps and landings - they can launch, but usually land in a haphazard manner at best. Only a few seem to be capable of anything remotely near the performance and control organisms show. We should probably mention it, but not terribly extensively. Longer discussions of it should be in the robot locomotion page. Mokele (talk) 20:29, 5 July 2009 (UTC)
Citations - I'm awful at formatting
Sorry, I'm awful at putting citations in the right formats. Here's the relevant papers:

Would it be possible to add to this page a section on the history of jumping, including the origin of the jump? There is surprisingly little information on the internet regarding jumping history, and I would really like to see this information here on Wikipedia. —Preceding unsigned comment added by 18.104.22.168 (talk) 11:02, 2 October 2009 (UTC)
- Do you mean the evolutionary history, or the history with regards to various sports? The former is poorly known, while the latter is not the topic of this article. Mokele (talk) 11:47, 2 October 2009 (UTC)
Jumping activities: an important section?
Is it really helpful to anyone to provide an exhaustive list of jumping activities in this article? The list keeps getting longer and longer and now we are starting to see the addition of images of running horses, etc. With the exception of golf, practically every sport known to mankind involves jumping, and even golfers sometimes jump for joy.

- LOL! So the critters are doing in the whole list eh? (grin). I will comment that lists always do seem to grow unless there are guidelines, and one way to cut them down is to take the critical parts of the list and put them into a narrative form. Here's a suggestion: How about the list includes those activities (say long jump wherein jumping is the specific purpose, as opposed to, say, Basketball, where jumping is simply incidental. But if people jumping is on the list, we critter-editors want critters in there too! (smile).
- I'm thinking that a good solution would be to move the entire list to its own article (e.g., List of jumping activities) and then add a sentence to the intro that says something like this: Jumping is a key feature of various activities and sports, including the long jump, high jump, and show jumping. That would solve the problem in this article, but I'm still undecided about the value of an expansive list of jumping activities. Lambtron (talk) 14:26, 14 January 2010 (UTC)
