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.
Kangaroos Can Jump 30 Feet High
Welcome to quot;DiscoveryWorld Safari.quot; On today's episode,the kangaroo. Kangaroos live inEastern Australia in small groups calledtroops or herds. However, Australiansknow them better as mobs. Kangaroos are classifiedas marsupials.
And are in fact the largestof all the marsupial species, standing over 6 feet tall. They are primarily herbivores,with large, powerful hind legs. Their legs can leap toabout 30 feet at the time and travel as fastas 30 miles per hour. Perhaps their mostfamous characteristic is their pouch, whichIS A fold of skin that can hold theirnewborns, known as joeys.
Joeys stay in thepouch for 10 months before they leaving,though they do venture out as young as fourmonths old to graze on grass beforereturning to the pouch.

Kangaroo vs Jumping Stilts
My mission is to find the planets ultimate animal adaptations and this time I'm on a journey into the heart of the Australian outback. To survive here animals must learn to live with next to no water, to find and store food in unique ways and to move around on the red hot sand but what animal will have ultimate adaptation. Kangaroos are Australia's most iconic animal, the largest Roo's can cover over twenty five
feet or eight meters in a single hop or 1.8 mitres high. Moving around in the outback can be seriously hard work but these guys make it look incredibly easy some kangaroos can hit a top speed of over 40 miles or 64 kilometres per hour using their long tails to help them balance, the hopping motion is over long distances is more energy efficient than running
but how do humans compare in the hopping stakes. Meet Graham he is Australia's number one Powerskipper using these bouncy stilts he can almost exactly replicate the bouncing motion of the kangaroos but how fast could Graham go using his bouncy Kangaroo like legsé We took him to a nearby airfield to find out. Obviously Graham doesn't have a tail which makes him struggle
with balance and stuff so we're going to give him more of a chance by letting him run. Graham you readyé I am. Right lets go. Graham has one run to try to get close to his target of 60 kilometres an hour. He's quick! Come on mate a little bit more. Come on graham, nail it.
That's about it, he's quick tho, he's quick! Come on Graham. He's quick, he is quick but we've left him ok. Graham looked pretty fast on the runway but how did match up to a kangarooé Graham hit an impressive a 31 kilometres per hour but unfortunately that's just half the speed that a kangaroo can reach but I'll tell you what a kangaroo can't do, is this. Anyway from one of Australia fastest animals to one of it's slowest.
