Because they are overcome with emotion and excitement at the fact they remembered how to actually do one
Assuming you are talking Olympic style sparring, punches to the face are illegal. Punches to the body are much more difficult for all judges to see and hence score, so they may raise a hand and shout to try and signal the point. Mitch
When I hit my opponents, normally they drop in pain and agony and that's how people know I've won a point
Lol, funny responses. Its a trick used to help 'sell' the punch, even if it didn't fully connect with the Hogu.
Yup, what SyDiko said. Also, you occasionally see the one who has been hit raising their arm in celebration, which gets really confusing for the judges. You only have to delay a judge for 1 second and then their button pressing isn't counted, which might affect the score.
