First and foremost, a distinction needs to be made betwen the
sporting arts you mention and proper martial (from the Latin
martialis, "pertaining to Mars, God of War") arts.
As you can see from our Historical Manuals section, there are a number of extant medieval and Renaissance
fechtbucher ("fight books") detailing the various ways one may kill his opponent. Entire European martial systems were methodically fleshed out, complete with illustrations, but their ultimate goal was to inflict maximum damage, not win prizes. Even the manuals on German
ringen (wrestling), such as the Codex Wallerstein, were combat-oriented.
Thus I assume that by your statement that there is "more info around about traditional martial arts from Japan and China than from Europe's own tradition", you are talking about the sporting arts at post-Renaissance fairs. Because they were forms of entertainment, I would not lump them in the same category as European fighting arts.
That having been said, the
Journal of Manly Arts is a good place for you to start. It covers European and Colonial Combatives from 1776 - 1914, including sporting arts.
