Javelin Throw

Javelin is part in the Athletics, after a run-in, in which one tries to throw a Javelin as far as possible. The spear should countries in a fairly narrow sector in which the tip of the spear must hit the ground first.

In the 18th century, the present-day spear throwing spear port developed by the Scandinavians. The Sweden and especially the Finns showed themselves for decades, true masters in the Javelin throw. Javelin throw was first recorded in 1906 in official Championships in England. It became an official Olympic Athletics discipline for men inLondon in 1908 and in 1932 in Los Angeles for women. It is also part of several combined events.

[hide] *1 Rules  ==Rules[ Edit] == Bregje Crolla, Dutch record holding Javelin throwThe Spear is thrown after a run-in with the run course is a minimum of 4 meters wide and 30 meters long, preferably 33.50 m or more. In addition, the following rules apply:
 * 2 Material
 * 3 Technique
 * 4 Records
 * 5 Top ten best pitchers of all time
 * 5.1 Men
 * 5.2 Women
 * 6 world record development
 * 6.1 Men
 * 6.2 Women
 * 7 Javelin throw at the Olympics
 * 7.1 Men
 * 7.2 Women

==Material[ Edit] == The Spears were first made of wood, but nowadays of metal or carbon, in each case they have a metal tip and the diameter is around. Around the center of gravity is a handle of cord made. A men's Spear is 2.6 to 2.7 metres long and weighs 800 grams. A women's Javelin weighs 600 grams and is 2.2 to 2.3 metres long, At youth andmasters athletics are also used lighter Spears, Spears of 400, 500 and 700 grams are in use.
 * The spear should be held in the Middle, the point should be at the Centre constantly run and approximately in the object direction.
 * The athlete should quit the run-up the Javelin landed.
 * The athlete should the curved, white line at the end of the run, or the side extension, do not touch or exceed. Not when leaving the run-up after the Javelin landed.
 * The spear serves with the point to hit the ground first. The spear does not get stuck in the ground.
 * The spear must be within the sector lines countries. These are lines that have their origin in the so-called ' eight feet point ', eight feet before the end of the run course.From there they make an angle of 28,65 ° with each other.
 * After the Javelin landed, the pitcher leading up to leave, this is the case as soon as he/she has left leading up to the side, or more than 4 m from the centre line is run away. The jury can then measure.
 * During a match should any athlete generally throw three times, after which the best eight athletes are allowed to create another three throws.

In 1956 caused a Spanish Javelin thrower large stir: with a kind of turn-throw he came to distances of more than 100 meters. There are pendulum technique completely changed the character of the Javelin throw, was one for the international athletics world uniform rule drawn up, the spearhead during the start-up must always in the object direction. But even without the revolutionary turn engineering went one further and further objects. When in 1984 distances of more than 100 meters, threw the IAAF decided for security reasons to shift the Centre of gravity of the spear, allowing the thrown distances decreased with 15 to 20 metres. In the meantime, however, the Javelin throw again regularly over 90 meters far. In 1991 the rules were altered to a new type of spear with a rough surface to rule out. In the women's the model in 1999 changed. The old models, both the men and the women, had ever better aerodynamic properties which make them flew further, but making it more and more often happened that there is disagreement arose on the validity of the throw: hit the point first to the ground or not? ==Technique[ Edit] == Personal best by Elliott Thijssen*The other three object elements within the Athletics (shot put, discus throw and hammer throw) are rotation throws: the object (st) there is limited in a ring of diameter and is already running speed at the given device. In Javelin throw, on the other hand, is in a straight line running up. The spear should be shed before the end of the run-up and Furthermore, the pitcher itself not the discard line pass. This makes the technique of the Javelin throw is totally different than the other object parts. The art is to combine the most powerful possible Centre with the fastest possible run-up which also still in as short a time as possible should be ground to a halt – a biomechanicallyinteresting puzzle. There is more, the spear must be thrown accurately under the good corner because then the flight characteristics of the best use of the spear. ==Records<span class="mw-editsection" len="325" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">[ Edit<span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">] == <p style="margin-top:0.5em;line-height:22.3999996185303px;color:rgb(37,37,37);font-family:sans-serif;">The world record for men was thrown on 25 may 1996 by Jan Železný.

On those plays of London was there still a distinction is made between the Middle group and the free style. In 1912, Stockholm there was a general competition and in addition a combined competition in which both left and right handed had to be thrown. From the 1920 games, however, this was abolished. Also for the first time In 1932 there was an Olympic competition for women organized. ===Men<span class="mw-editsection" len="325" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;"><span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">[ Edit<span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">] === ===Women<span class="mw-editsection" len="326" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;"><span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">[ Edit<span class="mw-editsection-bracket" len="1" style="color:rgb(85,85,85);">] ===
 * In the first part of the dash is the spear usually held horizontally by hand next to the head. The gait is very personal and is not substantially for the performance, it is important only that exactly that speed is reached where the best Centre with it can be done. A pass or five before the Centre is brought backwards the spear: the shoulder belt is now parallel to the walking direction and the pelvis also nearly, the Spear is held about crest height with the spear, which stretched arm right past the head forward points. By the transverse attitude of shoulders and pelvis are the last fit fit to ' cross ': If the right leg (for right-handers) passes the the left leg moves forward and the legs are crossed; the action of the left leg looks like ' paw-about ' at ice skating, the foot is almost perpendicular to the feed direction. The foot of the right leg is also sometimes almost perpendicular to the feed direction posted but the foot in the walking direction places also occurs (Jan Železný) so that the right foot is perpendicular to the normal walking position.
 * The last time that the left leg marketing creates the ' banana '. The upper picture shows both crossing the legs as the banana: the left hip leads the movement, the left leg pointing a powerful marketing backwards and the hull also tilts a tad backwards (at old techniques much more). This ' banana ' from head to foot to hip marketing leads to tension on the left making it left lane after the outlet the faster it can go forward. (The preload principle comes in all techniques of Athletics emerges: a muscle first racks (the wrong way), means that he can move faster then.) The left leg passes then quickly the right leg and Lands shortly after the right leg has landed for the last time. The right leg of gravity about right under the lands while the left leg a piece is placed before the body. A good technique is that leg all stretched out, causing the left hip is fixed. That hip can only as a pole vault cant go up.
 * The placement of the left leg for the body means that the pitcher is strongly braked, but care must be taken to ensure that the kinetic energy of the pitcher is transferred on the spear. This is achieved by the right side of the hull to move forward quickly, or better said: to move, because the body had already speed of the run. After placement of the left leg, the right side of the hull the left catch up; the axis of rotation of this movement runs from left hip to left shoulder (which hardly shoulder moves relative to the hip, see the photos). Meanwhile, the throwing arm pointing backwards as long as possible, allowing the ' span ' arc can arise: the line of hand to right shoulder to left hip is an arch that curved so should be possible. This span arch contains much preload. There is also tension/torsion in the hull: the right hip is raised while the shoulder belt as long as possible at right angles to the walking direction remains. See the second picture. All these for voltage is used to finally the spear really to pay off. The throwing arm is as straight as possible and the Spear is released if the arm the shoulder passes, like the third picture shows, where the spear just has left the hand of the pitcher. The discard rate of the Spear is at good pitchers anything above 30 m/sec, at good pitchers something underneath.
 * Finally, it must still be braked. If the left leg was well placed, is much forward speed already gone and what remains is a little vertical speed (and the great speed of the Spear of course). Some pitchers will therefore forward up and countries on both hands, just before the discard line. Most object (st) ers only make a very large and possibly one or two more small steps in order to come to a halt.
 * Technology Variants. Throwing arm: right at the start of the Centre can point out backwards or the throwing arm to left back, in that latter case, the hull is rotated and the Javelin throw more of a stronger rotation throw (world record holder Jan Železný did that). Elbow: in deploying the throw flexes the elbow at some others only slightly, to about right angles; the latter leads rather to elbow injuries. Shoulder axle: at the time of shedding the throwing arm are completely in line with the shoulder axle, something up there (Steffi Nerius for example) or there just below (Železný).
