Competition is about winning, outscoring, proving. Good game but no more than that. It brings about a competitor mindset, a fighting mindset. Once again, good game.
Martial on the other hand is a totally different field of operation and thus a totally different mindset.
The mindset is not how to win or outscore or prove. The mindset is to end. To finish or be finished. No games, no sparring, no round one and two and three. No fighting.
When Jigoro Kano created judo, he added a safe, non-compliant, 'competitive', method to test the techniques' effective; this was called randori.
Before judo, jujutsu was wholly 'martial', and competitons were frequently fatal.
Anyway, one day, the Tokyo police force held a contest between judo - people who trained in a 'sport', 'non-martial' fashion - and a jujutsu school - people who trained in a 'martial' way.
The judoka wiped the floor with the 'true martial artists', and the Tokyo Metropolitan Police had judo taight to their officers.
Then there's Brazilian Jiu Jitsu: the Gracies took on all-comers for decades, defeating people who trained compliantly in teh De4dly techniques.
You wouldn't last thirty seconds with a jiu-jitsuka: deal with it.
