Roughly how much leg bend should there be in takeoff to maximize potential use of leg strength while converting as much of the force into upward momentum as...
As far as I know there is no optimal leg bend. Here jumpers differ quite a lot, which depends on the type of muscles you have (and how they are trained of...
1. The simple answer is it varies. 2. There have been studies done - do a check under Dapena 3. Your premise is unfortunately incorrect Denis Doyle ... From:...

I am stumped. I've heard a few different arguments on training theory for squats and jumping higher. Perhaps it's based more on the person, or perhaps any of...
Hi Scott A little more clarification. The force loaded onto the takeoff leg occurs as a result the combination of jumpers mass and the resultant vector of the...

Hi Dan What doesnt help is that you can find individual athletes who will claim success for all the options you have listed. In addition some will say go full...

Thanks. Even though you didn't answer my questions this was basically the answer I was looking for I guess haha. Of course this would raise a new question. If...
Hi Dan Cant make it too easy can I :-) Not all do full squats (see Dwights earlier post on squatting) Joint angles are bigger in full squats therefore muscles...

My strictly amature, non-scientific response to squats is that the leg muscles must fire much more quickly to jump than they do when you lift. However, you do...
Hello everyone. I have been greatly enjoying and benefitting from this forum. It is a fantastic resource for us young coaches. I have a question to throw...
Hi Jessica Its usually under-rotation. Can also be that the high point is wrong Solution 1 is to increase the rate of rotation or maybe lift legs and end the...

It sounds to me like the jumper is not maintaining "inward" lean on takeoff. This would keep him over the bar longer, and provide his center of gravity with ...
Without seeing him it could be quite a number of things I am assuming you mean FRONT corner for landing?? That sounds like a tight run with very small steps. I...

Genius: I'm responding to your post without benefit of reading any other replies so forgive me if there's some redundancy here. From the coordinates you gave...
Usually it is because the jumper is not spinning fast enough about an axis that is parallel to the bar; or, sometimes, because the apex (high point) of the...
Coach Stones: Are you measuring from the right hand standard? out 14'5"?? and your take off spot is right at the standard?? So if he is jumping 2' in from...
With watching people jump I would say she needs to arch her back and kick her feet as soon as her back is over the bar. In doing so it will get her feet out of...
Genius: I would give it a range of 13' 6" (4.10m) to 14' 5" (4.40m) from his take-off position. So, 11' 6" (3.50m) to 13' 6" (4.10m) from the inside part of...

... She actually does a great job with her rotation and tends to land near the center of the pit. She has beautiful form over the bar and is very fast when...
Take some side-on video See how the bar/body distance looks at different parts of the clearance. This will give you more information as to where the high point...

The only way you can be sure that the aproach will allow the jumper to 1. reach the takeoff point, 2. be leaned away from the bar properly, and 3. be headed...
Hmmm... I meant an arc on the ground. The other advantage to a geometric construction of the approach is that it is easy to adjust when you want to change the...
But all other things aren't equal though :-) Denis Doyle...

What changes if you don't change it? Run at the same speed; take off by coming out of the curve during the takeoff drive; follow the curved approach path in...
Out of curiosity, did anyone catch the 2005 texas relays. Scott Sellers, a high schooler, out jumped everyone at the meet by clearing 7-5 in his division(high...
