This is so distasteful to me that I haven't been able to watch much fencing. Fencing is fast enough that it would take a lot of viewing to really understand what's going on. So, this has really hampered my appreciation. Appropriate automated video editing could really help me out.
Do they scream like this at practice? Do they practice the screaming? It would be one thing if they vocalized as they struck, as in many martial arts. But this delayed "maybe I got a touch I guess I should ask the judge by screaming" just seems silly.
