I think it's probably true for many players that "having an audience improves their motivation.
However, I don't really understand this "fact" as I have been athletically illiterate all my life, thoroughly avoided team play, and only played individual sports such as tennis and skiing.
For example, during a tennis match, when I'm thinking about how to hit a service shot, if people are cheering loudly for me, I comt to think that
"Shut up! I can't concentrate, so keep it down!"
When I saw a TV broadcast of a sumo tournament without an audience, I was so impressed by the tranquility of the battle that I thought, "Sumo is such a beautiful sport.
A baseball game where they yell at the opposing pitcher, and a Kendo game where they can get in big trouble if they try to yell at a player -- Can we just call these "cultural difference" ?
Of course, I hate any sport where it is "normal" to have players (not spectators) yelling at opposing players during a game.
Furthermore, the words "away" and "home" are already not "beautiful" in sports competitions.

Therefore, I would like to affirm "no audience" not reluctantly, but logically and positively.
I believe that there is a beauty in sports events that are held without spectators that we do not yet know.

Well, I am well aware that there are "few" or even "no" people who agree with my opinion.
