Li Liyin breaks women's 69-kilogram world record

Shanghai, 12 October 2005


China's Li Liyin broke the world record on Wednesday in the women's weightlifting 69-kilogram class snatch with a lift of 125 kilograms. Li topped the snatch world record of 122 kilograms set by compatriot Liu Chunhong at last year's Olympic Games, while her total weight of 275 kilograms matched that set by Liu in Athens.

Li became the third Chinese woman to set new marks this week in the China-dominated sport at the country's national games. Olympic champion Chen Yanqing smashed all three records in the 58-kilogram weightlifting class on Tuesday. Li Ping on Monday set new records in the 53-kilogram clean and jerk and total weight.

Why are the weights not in rounded numbers of kilograms? Makes you wonder if they have been converted and rounded off to the nearest kilo...

Daniel wouldn't do such a thing, surely?

Bud,

If you visit www.iwf.net/iwf/doc/technical.pdf you will see the rules of the sport. The smallest weight is 0.5 kg, so there is a 50% chance that the actual amount lifted was a round number of kilogrammes.

That means that there is also a 50% chance that the actual amount lifted was not a round number of kilogrammes.

When you see rounded numbers like that, you cannot get any information about what units they were in originally. All you can do is try to see whether or not they are "logical" choices. If you see 25 and 50, they are probably in original units. If you see 27 and 52, probably not.

Bud,

If you bothered to check the website, you would have seen that weight-lifting is a metric sport - apart form the 0.5kg weight, all weights are whole numbers of kilogrammes. Does this answer your question?

And if you try to be a smart-ass and use pound weights, then you are disqualified.

And how would you know this, Daniel?

Are you speaking for every event and every gym in the world?

Or are you being a smart-arse?

Martin, I did not look at the website, I was only responding to your post which said "The smallest weight is 0.5 kg"

"And how would you know this, Daniel?

We are talking about competitions. Like the Olympic events. The rules for every weightlifting compettion require the plates not only be metric (in kilograms) but they be a specified mass. They must also conform to a sprecified metric dimensions. The bars and the collars must also be to specified metric dimensions as stated in the rules.

The people who run the competition events don't give a hoot what you do in the local gym. You want to be qualified for any event and if you break a record and you want that record recognized, then you follow the rules. Don't like the rules, then don't compete. That simple.

And because they don't call it "mass-lifting" does that render it wrong/bad/unruly/etc?

Surely you should be saying that they use newton-metres? At least this would be consistent with all your other ideas.

Am I right, or have I got it hopelessly wrong again?

Weight-liftingis the correct term because they are actually working against gravity. There are minor variations in the force required dependiong on where you are on the earth's surface. Firstly, there is a 0.5% variation in teh force due to gravity between the Poles and the Equator. Secondly, at sea-level there is a bouyancy effect of about 0.01% due to the mass of air being displaced (Archimedes Principal). At altitude, the bouyancy effect is less because the air is less dense (In Johannesburg and Denver for example, atmospheric pressure (and hence bouyancy effect) is typically 17% lower than at sea level.

You are doing the same thing whilst standing, walking, sitting etc.

Who cares as long as the sport is metric and the metric amounts are rounded numbers and the records are kept in metric for all time.

In other words "Who cares so long as I contradict myself about all the things I say about metric".

Come on! Own up! You're secretly on the imperial side aren't you?

Woah! I just noticed Danial's hidden message in this thread! Check out the surname of the woman named in the subject!

Very clever! (and possibly backs up my last claim)
