For the record, that guy with the backheel penalty kick, he's recieving sanctioning from the local FA, including a match ban.
What?!? Why? He scored didn't he? Same with the backflip guy: he did a fancy move, thereby deking the goaltender and he scored! What's the problem? I thought they were both brilliant. Just like combat sports: protect yourself (or your goal) at all times.
They're just jealous because they can't do it!
Technically it ain't a backflip . . . //:=|
Technically - who cares? Just to humor you though (insert inquisitive, childlike voice here):
"What is it really called orthonorm?"
Really it depends on the sport you are in. Backwards rotation is not necessarily a "back flip". A somersault is actually more accurate here. Now the sorta somersault and the like can be described as well.
The nomenclature of acrobatic movements began to get sloppy and imprecise especially with the advent of contemporary gymnastics and worse yet ice skating and then all the skating, free running, and the like.
The nerd in me wants to call it something like a running aerial back somersault on about a 45 degree angle ending in a loss.
We could get more precise and describe the use of his arms to generate the motion as well.
But in the end it is pretty cool.
Used to help coach and judge a sport where acrobatics were involved, so I gotta little caught up in the terminology.
