Wrestling is a combat and force sport with full body engagement and without additional aids. In the Olympic Games of the ancient world wrestling (named Pale) was one of the five disciplines of the so called pentathlon. In addition, wrestling was also a single discipline. In ancient times, the athletes performed the fight naked. They were not divided into different weight classes, as they are today.
