Ancient Olympic Games

Boxing: Ancient boxing had fewer policies than the modern sport. Boxers fought lacking rounds until one man was knocked out, or admitted he had been beaten. Contrasting the modern activity, there was no rule next to hitting an opponent when he was losing.
There were no mass course within the men’s and boy's divisions; opponents for a game were selected by chance.
As a substitute of gloves, ancient boxers wrapped leather thongs (himantes) around their hands and wrists which left their fingers open.

Discus: The ancient Greeks well thought-out the rhythm and accuracy of an athlete throwing the discus as vital as his power.
The discus was made of stone, iron, bronze, or lead, and was bent like a soaring saucer. Sizes mixed, while the boys' division was not normal to throw the same load as the men’s'.

Jump: Athletes used lead or stone jump weights (halteres) twisted like telephone receivers to boost the duration of their jump. The halteres were held ahead of the athlete during his rise, and powerfully forced behind his back and dropped throughout his plunge to help propel his body further.
