Boxing weigh in + science + trainers lies??
Discussion
Mods technically this is a sportish question but if you read on it is actually one for the science/clever people of the lounge (possibly)!
Im not sure if anyone watched the boxing last night, however john murray did not make his weight, he was something like 0.08kg over. Now after trying to drop the weight within the specified time he could not do it.
At the end they were interviewing his trainer to get his reaction, to which he blamed the carpet the scales were on for making his boy over weight.
He said if the scales had been on a hard floor he would of been under no problem, is this true and if so how/why?

having scales on carpet is daft and doing judo, Ive weighed in often enough to know it skews the result, the trainers fighter will have been weighing himself constantly on proper scales right up until the weigh in so he knew he was on target. That a boxing contest would have scales on carpet beggars belief really.
The carpet exerts pressure on areas of the scale that it wasnt designed to have, the 4 pressure points should just be at the 4 corners, the pressure of the carpet in the middle of the base could well raise or lower the result depending on the scales internal workings, I assume they were using proper sliding weight scales.

But the trainer was arguing that the carpet was increasing the reading, wasn't he?
yes, the carpet, could create a slight focusing of pressure on a point towards the center of the scale and skew the reading upwards, whether that would actually make the reading go up would depend on the type of scales and their internal workings. I think the bloke was probably just a bit too fat and hadnt spent long enough in the sauna.
ks. how does the carpet being under the scales which are under the person affect the person scale interface?Gassing Station | The Lounge | Top of Page | What's New | My Stuff
