In 2006, I (Lance Wicks) notated two days of Judo at the 2006 Commonwealth Judo Tournament.
The purpose of the notation was to do a statistical analysis looking to prove the hypothesis that the number of attacks made by a player had a correlation with winnning the match. The results are shown below: Summary of the 2006 Commonwealth Judo Tournament.
The notation was done manually with a custom paper form. Each attack was recorded as were scores.
This data was then entered into a spreadsheet for analysis.
As the document above indicates, a relationship was shown between attacking more and winning. Included with the results is a set of simple training drill ideas that have been designed to help prepare Judo athletes for the format of a tournament of this type.
