I am noticing lots of swimmers do over-dramatic touches at turns and at the finish to ensure they can show they touch with both hands. That is especially important for breaststroke and butterfly.
The touch should always be the natural conclusion of the stroke and not slow it down in any way.
A fast touch is very important.
In the breststroke a double-touch can happen above or below the water or on the water-line, as long as the hands are on the same horizontal plane and do not stack completely on top of each other and touch at the same time.
I see many swimmers touching and dramatising the simultaneous touch with both hands at the same level. I am under the impression they do that to avoid disqualification. But this slows down the swim.
Hesitation to touch or to emphasize the dramatic double touch slows down the swim and it is not in the best interest of the sport for this to happen.
I think swimmers should concentrate to perfect the stroke and touch as fast as possible and not worry too much about the swimming judge seeing the touch correctly.
If it happens that a disqualification occurs but the swimmer is certain that the double touch happened correctly, I think that the disqualification should be protested rather than slowing down the swim to get an over-emphasized clear touch.
If there are many protests the sport will have to move to instal cameras above each lane so that in case of query a judging team can monitor the camera footage to get an objective look at the swim. #swimfast #swimskilful
Other sports already introduced camera monitoring I think that swimming should invest in this technology.
