Re: Comparing... grunts???
i believe grunts are allowed at the moment you are hitting the shuttle. in other words, you are not allowed to make any noise when your opponent is hitting.
i think that is reasonable. and i haven't seen (erm.. heard) anything too outrageous yet.
in badminton singles, as almost all shots are off the base (center of court), most of the energy would be used in just getting to the shuttle, grunting too much or loudly will have detrimental effect. also, the movement is much faster in badminton than tennis, there would be no time for a long grunt.
IMHO, Hendrawan's must be the most disturbing grunt i have heard in the badminton court.
