The stadium is an architectural structure in which events take place sports, with space to accommodate spectators and other services. Outdoor sports stadium indicates the area of the forums that are home to the spectators. The term derives from the greek stadion, which was a unit of measurement equal to approximately 200 meters.
The oldest known stadium is the one in Olympia, in Peloponnese Western Greece, where they were led the Olympic Games of antiquity as far back as 776 BC Initially, the games consisted of a single event, a running race through the length of the stadium.
The practice of standardizing the race tracks at a length of 180-200 meters was followed later by the Romans . The human capacity to support the maximum speed is believed to decrease after about 200 meters of effort, a fact that can be observed in modern athletic competitions.
The remains of Greek and Roman stadiums have been found in numerous ancient cities, and among the most famous of them are the Panathenaic Stadium in Athens, which took place in the first Olympic Games of the modern era in 1896, and the Stadium of Domitian in Rome.
