  1. The Heaviest Heavyweight Judoka of Our Time

On the international sports scene, a small island nation in the Pacific Ocean- Samoa, achieved little success. However, Derek Sua went down in history. Firstly, he qualified for the 2016 Rio Olympic Games by Wild Card. Secondly, he is the heaviest heavyweight Judoka of our time at 175kg. 

Samoa is known for its Rugby, and that’s where Derek started his career- later taking up Judo. 

  1. There Were No Weight Categories At First

Keep in mind, until the 1930s, there was no division of Judokas into weight categories. In fact, the introduction of weight categories was strongly opposed in fear of losing Judo as a skilful art. Previously, everyone fought everyone and weight differences were not considered important. 

When Judo made its debut at the 1964 Tokyo Olympics it was a men-only discipline and there were just four weight classes, namely: Lightweight up to 63kg, Middleweight up to 80kg, Heavyweight up to 93kg, and Openweight.

The addition of weight classes was the first development in Judo.

  1. Women in Judo

The first Judo World Championships that included women took place in New York City in 1980. From then on, the World Championships would alternate each year between men and women, until 1987- when the two competitions were merged together into one World Championship.

At the 1988 Olympic Games, women were allowed to participate in Judo as a demonstration sport thanks to the determination of Rusty Kanokogi.

Up until 1992, only men competed at the Olympic Games. Since 1992, women were officially included in the Judo program at the Olympics and awarded with medals.female judoka

  1. Children and Judo

In the early days, the teaching of Judo to children was avoided as it was thought much too dangerous to teach children as it was a risk for them to use their skill outside the club. However, as a second development in Judo, many clubs are composed largely of Junior membership today.

  1. A Shift In Practice

With the inclusion of Judo in the Olympics, the style of the sport has changed over the years. For instance, there’s been a shift towards a contest style practice. In many clubs, this style is being taught- which transforms training into a continuous contest. This style of club could be considered more competitive.

Other clubs stress skill with repetitive movements, development of speed through practice and little resistance. Usually in such clubs, Kata is also taught. This style of club could be considered more traditional.

Striking techniques are prohibited in free practice and in competition. The only striking techniques in Judo are during Kata practice, which involves two Judoka practicing pre-arranged patterns together.
