Track Field Training How to Increase Your Vertical Jump
Hi I'm Les Whitley. I'd like to take a fewminutes now and talk to you about how to improve your vertical jump. Your vertical jump isagain your ability to push force into the ground to propel your body upward overcomingthe forces of gravity, traveling upward through space. Knowing where you start or knowingwhere your vertical jump is to begin with is a great way to start. Once you identifywhat your vertical jump is usually measured in inches you know where you want to go andhow far you want to progress from as little as a gain of one inch up to three inches overthe course of a six to a twelve week time frame is actually a pretty good improvement.Putting force in the ground means that you
have got to get stronger, utilizing exercisessuch as the squat, to develop a good base of power for the lower body but then alsomaximizing the transfer of that power through incorporating exercises like the power cleanor the overhead snatch, the olympic movements which involve very speed oriented movementsto that you are maximizing that power output in minimal time. The vertical jump is a veryquick movement. You are putting maximal force in a very short amount of time. The otherthing becomes technique ideally setting yourself up as a spring, springing and loading yourselfup into a position, not to overcompensate by staying too long in a deep position sothat the muscles become taxed and fatigued.
You want to set yourself up by causing a nicespring effect swinging your arms down which preloads those muscles engaging the musclesof the hips, the muscles of the lower body, the calves and then forcefully swinging yourarms up high to again maximize that vertical leap so arms start up high, forceful drivedown and then rebound for maximal height.
Orbitals Crash Course Chemistry 25
We spend a lot of time thinking about atomsas looking like this. There's a ball and there's a stick, and there'sanother ball and another stick. It's just a bunch of balls stuck togetherby these little wooden bonds. Simple. Pretty easy to understand, and thus â€” as you have probably come to expect â€” it is entirely incorrect. Nuclei really can be understood as littleballs, and that's more or less correct, though when you get to some of the bigger, less stable ones they start looking more oblong and weird like a rugby ball. Atoms are basically balllike as well, with electrons and a spherical cloud around the nucleus. But molecules, as we discussed last time,do not look like balls on sticks.
Bonds don't form into neat little lines. They form from overlapping electron clouds or shells, flowing around the nuclei of bonded atoms. If you really get down there andunderstand what they look like, they're like lumpy, clumpy globs of probableelectron locations. And these lumpy, clumps of probable electron locations do not behave the way you might initially expect them to behave. Oh no. That would be far too simple. They behave based on quantum mechanical, 3dimensionalwave functions, probabilistic distributions of electrons inspace.
And yeah, by the end of this episode, you're going to understand what I just said and it's gonna be awesome! Theme Music Let's start with water, because all the interestingthings on our planet start with water. It's also universally common, not just onour planet but in our galaxy and our universe. Case in point: In 2011, astronomers discovereda cloud of waterice surrounding a black hole that contains 140 trillion times more waterthan we have here on Earth. And while we don't have any confirmed worldscovered in water outside of our solar system, we do have some right here in our solar system.
Europa contains so much water, probably saltwater, that its entire surface is just ice. What did any of that have to do with atomicorbitalsé Nothing. I just felt like maybe I scared you with allthat quantum mechanics talk before the intro and I wanted to chill you out for a second. Okay, so water. We did its Lewis structurelast week, rememberé Each hydrogen bonding to the oxygen atom,and voilÃ ! But that drawing is linear, just a straightline through all the nuclei, and we know, just instinctually at this point,that water is a bent molecule.
But whyéWhy is water crookedé Unbonded atoms within a molecule generally like to be as far away from each other as possible, especially if they have the same partial chargeas the 2 hydrogens do with their partial positives. But something is keeping those hydrogens closertogether than they would like to be. So why on earth are they not stretched outas far away from each other as possibleé I ask this because if they were, the watermolecule wouldn't be polar, and if water was suddenly nonpolar we wouldall instantly die, as would all life on Earth. And suddenly, we realize that this seemingly normal thing that we knew about the world is really weird.
And weird stuff is my favorite stuff becauseit means interesting questions. Interesting questions I want to know the answerto. It's an even more compelling question than, quot;What the heck is a quantum mechanical 3dimensionalwave functionéquot; Well, of course, the answer to this questionhas a great deal to do with quantum mechanical 3dimensional wave functions,so let's start there. Oh, look!I've got a telephone cord! This is what old people used to use to gettheir voices into wires
