according to wikipedia, all that noise is necessary:
" This is because kendōka use a shout, or kiai (気合い?), to express their fighting spirit when striking. Additionally, kendōka execute fumikomi-ashi (踏み込み足?), an action similar to a stamp of the front foot, when making a strike."
If we're talking about Asian people from my area, if they had to drive to the field that would explain it. half of them would get lost, and the other half, if they left at 8am, would arrive at around 5pm, even if it were a short distance away.

Yeah - this seems similar to Karate when you use a Kiai the same way however also in competition Karate you have to kiai when you connect an attack otherwise it wont count to score even if it was perfect. I imagine kendo might be the same this way.
