Javelin Throwing
This is a very important factor in javelin throwing. Speed in the
legs can build up momentum in the run up so that the throw can go
further. Speed is also needed in the legs when pushing off the ground
as this combines with strength to create power that can be applied to
the javelin once thrown. The arm also needs speed so that the javelin
can be pulled through quickly, giving a momentum to also combine with
strength to create power. The power then applies a force onto the
javelin.
Agility:
This is the ability to change direction quickly, efficiently,
accurately, and combining speed with balance, power and coordination.
Agility is important to throwing the javelin. The body needs to
change direction 900 at the torso. Speed is needed (as above) which
needs balance so that the force of throwing the javelin travels
through the point. This enables a greater distance thrown.
Coordination is needed to be combined as when doing the technique at
speed, all the limbs of the body need to be in different positions
which at times can be difficult.
Balance:
This is the ability to maintain equilibrium. To be balanced, one must
keep ones centre of gravity over its area of support.
Balance is very important in throwing the javelin. Many times during
the phase of throwing, much of the body's weight is on one foot then
transferred to the other. This requires balance because without it,
the technique may not work effectively or there is a chance of falling
over. While throwing, the javelin, the centre of mass changes from the
back leg (right) to the front leg (left) to get as much force on the
throw possible.
Coordination:
This involves using the Neuro-Muscular System to produce smooth and
efficient movement. It also involves putting relevant motor programmes
into order.
Coordination is vital to throwing the javelin. There are a range of
different movements needed to carry out the overall task of actually

When one throws a baseball properly they are using there entire body to generate a large force to propel the baseball. A general throwing position starts with a person rotated 90 degrees from there target with there throwing arm 180 degrees from the target and parallel to the ground. The person then starts rotating their body back towards their target while there throwing arm starts bending until it is almost 90 degrees to their elbow, while the arm is bending at the elbow the throwing arm is rotating such that the arm rotates back almost 180 degrees from the target. Meanwhile the person is leaping forward with the leg that was initially pointed at the target while there other leg is planted into the ground. The person is bending at their waist and the other arm is rotating into their body. Around the point where the driving leg strikes the ground the throwing arm is rotating foreword at a tremendous angular speed and the person lets go of the ball. At the point where the ball is let go the persons body pulls the planted leg forward and the throwing arm finishes its motion towards the driving leg.
The fighter is then ready to initiate the movement phase: extension at the knee with a relative angle to the thigh of about 180 degrees, lateral rotation of the grounded foot between 90 and 120 degrees, and additional lateral flexion of the spine.
Roping is a sport that most believe simply to be timing and performance of the cowboy and the cattle. However, roping is actually much, much, more. One quality that is necessary for a roper to be successful is momentum. Momentum is the quantity of motion of a moving body, measured of a product of its mass and its velocity (Jones). This concept of momentum can determine what results are obtained by the roper. For example, when a cowboy rides a horse and the horse accelerates, the mass of cowboy and horse together gain momentum. In contrast to that the cattle that leave the shoot and accelerate to escape the rope also gains momentum. The amounts of momentum determine how far each can run in the arena before the rope makes contact with the animal. Another concept that relies on momentum is the rope itself. The cowboy is required to swing the rope with enough momentum to make the loop stand out a sufficient amount so that it is extended and open enough to secure around the animals head or heels.
A standing broad jump is a jump for distance from a standing position. It can be divided into four temporal phases: countermovement, propulsion, flight, and landing. In the countermovement phase, the subject squats to load up and extends the shoulders and the arms. In the propulsion phase, the goal is to generate enough force to propel the body forward. The person must stand erect in full extension of the trunk, hips, and knees. Then, the person flexes at the hip and the knee, which results with the trunk being rotated in a forward direction. Next, the arms become slightly flexed to hyperextension, to full flexion. Prior to the flight phase, the body goes into full extension. The flight phase begins as soon as the feet have left the ground. During this phase, the body stays in full extension or can become hyperextended. Towards the end of the flight phase, the trunk rotates forward in an anterior direction along with minor hip and knee flexion just before landing. During the landing phase, the knees and the hips are in maximum flexion and forward rotation of the trunk. There is also arm movement by moving both arms in the vertical direction to improve jumping distance. At the onset of the jump, the arm swings forward and during landing, they swing back and forth.
Depending on who you ask, there are many different things that come to people's minds when one hears the word, chivalry. Some might say: knights, castles, horses, damsels in distress, Knights in shinning armor.... i could go on and on. I think of all these things as well, but I also think of Jousting. In a time when courage, honor and integrity were valued jousting was not only a sport, but a way for knights to prove their skill and courage.
In rugby, however, the primary rule is that you can only advance the ball by running
First of all, the rules of football require one to equip himself with approximately twenty pounds of equipment, including a helmet, shoulder pads, and girdle pads. This is because football has the most contact involved out of all sports. In a football game, the norm is that the home team wears colorful jerseys and the visiting team wears white jerseys. Moreover, if a team’s offense is on the field, their defense is on the sideline. A team’s offense includes a center, who snaps the ball to the quarterback. The “QB” then has a choice to run with the ball, hand it off to a running back, or throw it to a wide receiver. The quarterback has an offensive line to protect him from the assailing defense. If a teammate happens to score a touchdown, he earns his team six points, which allows for the kicker to kick an extra point, and give his team a total of seven points. However, if the offense fails to travel at least ten yards within four attempts, or “downs,” they have the opti...
Making up a small ten percent of the Greek army’s population, archers were not such a main force within battles. Mostly, it was those of the Hoplites that took a top spot in battle, a number of them being on the front lines along with cavalry and some of the reserve soldiers. Hoplites were the main reliance, backed up by the archers and lightly armored troops (Department of Greek and Roman Art, 2000, Warfare in Ancient Greece). Archers would obviously fire from a longer distance, so they weren’t as up front with battles as others in warfare. Behind the scenes workers, if you would like to compare them to something of that sort. Less seen, yet holding their own unique impact. Archers were not the Greek’s main source of firepower, they were equally as important and used frequently in Ancient Greek warfare.
I would use neutral pelvic placement for the One Leg Circle, since the essence of the exercise is stability of the pelvis and torso in neutral while being challenged by unilateral leg movement. Imprinted spine would be recommended for the Hundred since both feet are lifted off of the ground. Imprinted spine would help to maintain flexion in the spine, you could use neutral spine when the client demonstrates enough strength to maintain it during the exercise. 2.
Fencing is a method of personal expression and release. It is ultimatly a way of life for some. Nevertheless, this noble lifestyle is dying out. There are those who would convince others that classical fencing is a way of the past. In its place they would promote a sport that uses the same equipment and yet, is so different, that one cannot think of it in the same light. The controversy between these two poses the question "is Olympic fencing better than classical?"; A question that will require some research.
-Second, hip rotation also helps the runner to have a more natural and smoother run and again reduces the energy required to move the runner’s center of mass.
The Olympic Games were a vital part of Greek culture which was heavily influenced by athletics. Today, the Olympic Games are the world's largest presentation of athletic skill and competitive spirit. Thousands of athletes and spectators participate in this universal event. Revived in 1896, the Olympic Games had their beginnings in ancient Greece, and since then the event is very much comparable to modern Olympic events.
