Shot Put Introduction
Homer makes mention of competitions of rock throwing by soldiers during the siege of Troy. In the XVI century King Henry VIII was noted for his prowess in court competitions of weight and hammer throwing and in the XVII century English soldiers organized cannonball throwing competitions.
The rules of the competition were first established in 1860, when the throw had to be made from a square with sides of seven feet (2.13m). This was replaced in 1906 by a seven foot diameter circle. The weight of the shot was fixed at 16 pounds (7.257 kg). Bent arm throws were outlawed for being too dangerous and competitors had to hold the shot in the crook of the neck prior to release.
The sidestep action in the circle was invented in the United States in 1876.In 1951 Parry O’Brien (USA) refined a new technique. From a start position facing the back of the circle, O’Brien rotated 180 degrees to move across the circle before making the final release. This helped him become the first to break the 18m (and subsequently the 19m) barrier.
In 1976 Aleksandr Baryshnikov pioneered the rotational technique, similar to that used by discus throwers, which has become increasingly popular.
A women’s shot put competition with a 4 kg implement was first held in France in 1917. The inaugural IAAF world record dates back to 1934 with the event making its Olympic debut in 1948. Until 1927 women’s contests were also held with shots weighing 8 pounds and 5 kilograms.

Is it for me?
Shot putters must be big, have strong arms and legs and natural speed. They must summon the dynamic power to propel a heavy, metal ball (7.26 kg for men, 4 kg for women) as far as possible. Performance improvement will depend on improving this strength by various means, particularly weight lifting.
Introduction to the Discus Throw
March 26, 2008
Introduction to the discus
The ancient Greeks have described this event better than any other. They used stone and then bronze disks between two and six kilograms in weight and 21cm to 34cm in diameter.
The discus first appeared in the Ancient Games in 708 BC. In 1896 the discus was included in the revived Olympic Games in Athens. Throws were made from a pedestal that measured 60cm by 70cm. At the same time, the Swedes were throwing the discus from a 2.5m square.
In 1897, in the USA, the event took place in a seven foot diameter circle, increased to 2.50m in 1908. The discus itself was standardised in 1907 at 2kg in weight and 22cm in diameter.From the original static throw of 1900, styles evolved through the Nordic swinging throw to the current style, introduced by Clarence Houser (USA) in 1926, of turning and skipping before release. Both hands contests, where aggregates were recorded, were organised until the 1920s, when single hand contests became the norm.
In 1954 the concrete throwing circle was introduced, greatly increasing the possible speed of rotation.The first recorded women’s results, with a discus weighing 1.25kg, date back to 1914 (USA) with contests also held around the world using 1.5kg implements. A standard 1kg discus was adopted for the Olympic Games in 1928 while the IAAF ratified its first official world record in 1936.

Is it for me?
The discus is a throw without utilitarian value, a child’s game for all ages. This ballet without music has fascinated since remote antiquity, when great sculptors used the discus thrower to symbolise athletics. The discus thrower must add a wide reach, speed on the turn and a sense of rhythm to the shot putter’s sturdy skills. Success means taking advantage of the centrifugal force engendered by whirling inside a concrete circle 2.50 metre in diameter before a final energetic release. The whole body contributes to the action. The discus thrower is a dancer who performs the most complex and beautiful choreography in athletics.
For the Expert
Athletes with exceptional rhythm and orienting capabilities are especially well suited to discus throwing. They must also posses musculature with great speed strength and the shoulder and chest muscles are of primary importance in the final acceleration of the discus. Good hip, trunk and shoulder flexibility is also advantageous.
External influences in discus throwing
The men’s discus was standardized to a weight of 2 kg and diameter of 22 cm in 1907. Women’s discus was not included in the Olympic Games until 1928 and weighs 1 kg. Since 1928 the discus is thrown from a 2. 5 m diameter throwing circle. This requirement limits the possibilities of giving the discus the necessary initial acceleration. The one and a half turn technique prior to release has become universally established with the world’s best despite some attempts with two or more turns. The movements of the athlete include a flight or transfer phase which introduces the decisive release phase. The quality of the execution of the rotating movements is considerably influenced by the characteristics of the throwing circle. Improved conditions are provided for accelerating the discus when the friction is greatest. The friction between the athlete’s shoes and the throwing circle is especially reduced during rain which leads to the risk of slipping. It is therefore, very difficult to provide the required standing stability during the main accelerating phase prior to release. Wind conditions in the stadium influence the discus flight. Head wind generally improves the distance rather than tail wind. The discus must land in a 40° sector.
Biomechanical factors in discus throwing
In the movement sciences the athlete’s rotation movements are divided into
1 two-legged start phase pre-acceleration
2 one-legged start phase pre-acceleration
3 stance release transfer
4 one-legged release phase final acceleration
5 two-legged release phase final acceleration
The two-legged release phase is of major importance as it represents the main accelerating phase of the discus. Approximately 70% of the release velocity are produced by the thrower during this movement phase. The execution of the final acceleration phase is of special movement technical importance because the release velocity is the characteristic with the greatest influence upon the distance thrown. All prior movements serve to prepare the final acceleration. Starting swing, start phase and the transfer lead the thrower into the so-called power position. In this phase the discus already experiences a pre-acceleration up to 30% of its final velocity. The temporal pattern of the movement sequences is performed individually different. It is, however, amazing which consistency world class athletes demonstrate in their movement rhythm. This excludes the possibility of making universal recommendations for the rhythm. However, it would also be incorrect to neglect the pre-acceleration phases because of their small influence upon the throwing performance. An optimal power position can only be achieved if these are executed safely and reproducibly.
The power position itself must provide beneficial conditions to facilitate an optimal throw. The discus should be accelerated to a velocity of about 80 km/h over the longest possible acceleration path while utilizing the pre-stretched chest and shoulder musculature. The relationship “greater release velocity = greater distance” only has theoretical validity. There is an individual optimum as seen in the long jump or triple jump. It is therefore, quite possible to release the discus at an excessive velocity. This usually results in an uncontrolled throw with negative influences upon the other performance determining characteristics and consequently the distance thrown.
The point of release should be as high as possible above the ground. This represents one of the few differences between men’s and women’s discus. Female throwers achieve lower release heights due to their smaller stature. A controversial theme is whether the release itself should be performed with both feet in contact with the ground. The “jumping throw” in which ground contact is lost prior to release is seen primarily in the men’s discus. From a biomechanical perspective the “standing jump” as performed by Lars Riedel (GER) and the world record holder Jürgen Schult (GER) and also the majority of elite female throwers is to be preferred. It is only possible to accelerate the discus up until the last instance prior to release if a solid ground contact is present. An optimal twisting of the shoulders relative to the hips and a throwing arm held far back are prerequisites for a good acceleration out of the power position.
Next to release height and velocity a third factor influencing the distance thrown is the release angle. At the elite level this lies between 33 and 38°. No data is available describing the extent to which throwers can adapt the release angle to the present wind conditions.
Training with coach Jerry Clayton
March 26, 2008
I have been training with coach in Auburn, AL at Auburn University for a few weeks and it has been awesome.
Having a training partner (Kristin Heaston, USA Olympian women’s shot put) to train with has been very exciting.
We are able to push each other harder in the workouts. Even though the workouts are hard enough the way coach writes them, we some how find a way to make them harder having mini competitions in our training exercises.
