Homer mentions competitions of rock throwing by soldiers during the Siege of Troy but there is no record of any dead weights being thrown in Greek competitions. The first evidence for stone- or weight-throwing events were in the Scottish Highlands, and date back to approximately the first century. In the 16th century King Henry VIII was noted for his prowess in court competitions of weight-throwing.
The first events resembling the modern shot put likely occurred in the Middle Ages when soldiers held competitions in which they hurled cannonballs. Shot put competitions were first recorded in early 19th century Scotland, and were a part of the British Amateur Championships beginning in 1866.
Competitors take their throw from inside a marked circle 2.135m (7.005 ft) in diameter, with a stopboard about 10 centimetres (3.9 in) high at the front of the circle.
The following rules (indoor and outdoor) are adhered for a legal throw:
Upon calling the athlete's name, the athlete may choose any part of the throwing circle to enter inside. They have thirty seconds to commence the throwing motion otherwise it counts as a forfeit for the current match.
The athlete may not wear gloves; IAAF rules permit the taping of individual fingers.
The athlete must rest the shot close to the neck, and keep it tight to the neck throughout the motion.
The shot must be released above the height of the shoulder, using only one hand.
The athlete may touch the inside surface of the circle or toe board, but must not touch the top or outside of the circle or toe board, or the ground beyond the circle. Limbs may however extend over the lines of the circle in the air.
The shot must land in the legal sector (34.92°) of the throwing area.
The athlete must leave the throwing circle from the back.
Foul throws occur when an athlete:
At any time if the shot loses contact with the neck then it is technically an illegal put.
