Title: Rules draft: weightlifting
Post by: kris on September 30, 2008, 12:28:02 am
The rules for our weightlifting meets have now been folded into the Virtualmeet.net Technical Rules (http://virtualmeet.net/meets/rules/). The current version (0.87) should be considered a first draft only in respect to weightlifting. This thread is here for gathering feedback: is anything missing? could anything be worded better? spelling mistakes?

THE TIME TO DETERMINE HOW VIRTUAL WEIGHTLIFTING WILL LOOK LIKE IS NOW! Once the rules start being actively in use changing them will be harder.

A few notes/questions on the weightlifting additions:

  • The clothing rules are currently identical with those for powerlifting: this means T-shirt and shorts, no singlets. Does this work or do you think singlets should be allowed? We prohibited singlets for powerlifting (http://virtualmeet.net/community/forum/technical-questions/45/msg267/#msg267) some time ago to underscore that we lift RAW and to remove the possibility to pass supportive gear as a non-supportive singlet. Personally, I think we should strive towards keeping the rules as simple as possible; having the same clothing rules for all lifts sure make things easier than having lift specific clothing rules. But if singlets are needed, we should certainly allow them. Thoughts?
  • Since this is common practice in weightlifting, the draft suggests using the Malone-Meltzer age coefficients (which start giving age handicaps after 30 years of age) for weightlifting. For the powerlifts, we use McCulloch (which starts at 40). I suspect the explosive strength required for weightlifting may deteriorate faster than the maximal power required for powerlifting so this discrepancy is probably in order, but thoughts on this would be welcome.
  • The weightlifts and weightlifting total will be calculated using Mel C. Siff's weightlifting formula (http://www.geocities.com/aedziepak/training/formulas.htm).
  • To my knowledge, there are no established total ranking classes in weightlifting to match the Elite-Class IV powerlifting classifications standard. The total ranking is thus a regular flat ranking in weightlifting. If anyone knows of any similar system in weightlifting that may be applicable, please let me know.
  • The maximum length of a weightlifting meet is 1.5 hours, i.e. the same as for other two-lift meets. Is this ok?
  • Is the current shoe rules also adequate for weightlifting or are they too restrictive?

    Quote
    e)   Shoes: Shoes must be worn on all lifts with the exception of the deadlift where deadlift slippers are also allowed. Any shoe or boot with an underside exceeding 5 cm/2 inches at any point, and shoes with metal spikes or cleats are forbidden. The use of any form of adhesive, including sand paper, emery cloth etc., on the underside of footwear is forbidden. Resin, magnesium carbonate, and “stick-type” sprays are not allowed on footgear. A spray of water is acceptable.
  • Is the terminology used in the rules correct? For example, should Olympic weightlifting be used more judiciously over weightlifting?
  • Do the technical rules and fault list for the snatch and the clean and the jerk look good or should anything be changed?

Besides these major changes, the rules set is the same as that for powerlifting. You still have to video tape your lifts from a good angle, weigh-in as usual, remember the day's newspaper etc. etc.

Over to you. Changes can be folded in up until the meet sign-up deadline expires on Thursday for this weekends weightlifting meet.

I think shorts and t-shirts will be fine, altho something sleeveless would be more natural, because of the shoulder movements. The powerlifting shoes section is pretty funny if you read it for weightlifting... as if anyone would use adhesives or a spray of water for this.  ;D  You could say weightlifting shoes are acceptable but not required. FYI generally a hard-soled shoe is what you want, so sometimes you'll see lifters in army boots or bowling shoes.

Thanks Kat, you brought up some good points. As a reference and comparison, here is the current shoe rules from the International Weightlifting Federation:

Quote
4.2 WEIGHTLIFTING FOOTWEAR
4.2.1 The competitors must wear sport footwear (called weightlifting shoes / boots)
to protect their feet and give them stability and a firm stance on the
competition platform.
4.2.2 Weightlifting footwear must be made in such a way that they do not give the
athlete an unfair advantage or additional support other than what is specified
in 4.2.1.
4.2.3 A strap over the instep is permitted.
4.2.4 The part of the footwear that covers the heel may be reinforced.
4.2.5 The maximum height permitted on the upper part of the footwear, measured
from the top of the sole, is 130 mm.
4.2.6 The sole must not extend from the footwear by more than 5 mm at any point.
4.2.7 The footwear may be made of any material or combination of materials.
4.2.8 There is no minimum or maximum height of the soles.
4.2.9 There are no restrictions in regards of the shape of the footwear.

We probably need to loosen up the shoe rules for weightlifting, but the question is whether we should go with the same rules for powerlifting or whether to separate them... As I wrote earlier, I think it would be great if we could have a single set of clothing rules that are shared between all lifts.

Not that I enjoy lifting in a singlet BUT it might make the weightlifting easier to judge.  It shouldn't be required, but possibly allowing a singlet might be helpful for judges. And you won't see anyone trying an Oly lift in a squat suit unless they've invented a straight-legged first pull.

Very good point! We will go with the no-singlet rule for this meet since we are so close to it already, but we should consider this further after the meet.


Title: Re: Rules draft: weightlifting
Post by: Domkratos on October 24, 2008, 05:01:03 pm
Thanks for the Oly lifting, guys! IMO it's a brilliant idea.
What I'd like to know is are there any strict requirements with regard to the split/squat styles and the full squat/power squat variations? The point is our gym's policy restricts dropping weights, so I had to learn always to maintain full control of the weight above my head which is a lot easier for me when I'm not in an ATG position. It would be great if you let me do at least my 'snatch' with straight or slightly bent knees. The C&J is a lesser issue in this sense. 
 


Title: Re: Rules draft: weightlifting
Post by: kris on October 24, 2008, 08:10:27 pm
Thanks for the compliments Vadim. :) I completely agree that the decision to include weightlifting was one of the best ones ever as it has brought another vibrant dimension to Virtualmeet.net.

It would be great if you let me do at least my 'snatch' with straight or slightly bent knees. The C&J is a lesser issue in this sense.

The basic answer is straightforward: you can do any variation of the lift that is allowed as per the rules but we will not make rule exceptions for any lifter unless it is because of physical limitations such as a handicap. Even though these are not official meets, I think it's important for our credibility that we have a firm policy on the technical rules. But your question is really whether the rules allow this kind of lift variation or not. If I understand what you are saying correctly (I may not), then yes, you don't need to drop into a squat or split. What matters is that you get the bar from the floor overhead to locked elbows and locked knees in a single motion without pausing or resorting to pressing. While some styles will naturally be more beneficial from a leverage point of view than others, you can accomplish this in many ways.

Does this answer your question?


Title: Re: Rules draft: weightlifting
Post by: Domkratos on October 25, 2008, 09:32:34 am
Yes it does.
So I understand that, when doing the snatch, as l long as I fix the bar overhead in one single motion: elbows locked, no pressing, the rules allow partial knee bent or no bent at all, right?
Thank you.


Title: Re: Rules draft: weightlifting
Post by: kris on October 25, 2008, 10:23:54 am
You can bend or not bend during the movement, but you need to finish by pausing with the bar fixed overhead AND locked knees.  Here are the rules for the snatch, I bolded the most relevant part.

Quote
1. The bar shall be laid horizontally in front of the lifter's feet on the floor. A thin rubber mat
not exceeding 2 centimeters/0.8 inches in thickness is allowed under the weight plates if
needed to protect the floor, but the bar may not be elevated off the floor in any other fashion.

2. The bar shall be gripped using a double overhand grip (the back of both hands pointing
away from the lifter). A traditional or hook grip (wrapping the fingers over the thumb of
each hand) may be used

3. In a single motion the bar will be pulled from the floor to overhead, with elbows locked out.
The bar may slide along the thighs and the lap during the lift. The lifter may split or bend at
the knees; however the lift is not complete until the legs and arms are fully extended.


4. After a visible pause in the final position with arms and legs extended and the feet on the
same line, the lifter may lower the bar to the start position by any safe means.


Title: Re: Rules draft: weightlifting
Post by: Domkratos on October 25, 2008, 11:30:21 am
You can bend or not bend during the movement...
That was exactly my question. The process. The result we can all see on TV or youtube.
Legs, arms, torso--every thing's straight and tight until the judge's signal.
The world class competitive lifters (i.e. the humans dealing with extreme weights) almost always go into full squat. As you say, it's biomechanics.
The point is I never saw an event performance when an athlete would do partial squat/split. I only read that sometimes, in order not to aggravate a knee injury, for example, they do partial movements.
Instead of raising this 'scientific discussion' ;D I should have put it this way: do you accept "power snatches" (and "power cleans" in the 1 phase, to get into the rack position)? Because, for instance (I quote wikipedia):
Quote
The power clean, a weight training exercise not used in competition, refers to any variant of the clean in which the lifter does not catch the bar in a full squat position (commonly accepted as thighs parallel to the floor).


       


Title: Re: Rules draft: weightlifting
Post by: mightykat on October 25, 2008, 04:00:04 pm
I agree. The lifts are full squat in competition. Partials/powers are for training. Otherwise, who would do full?

Variations that might be allowed typically include split vs. nonsplit jerks, for instance, but not an option not to go down.

I vote it should be that way here.


Title: Re: Rules draft: weightlifting
Post by: Chip on October 25, 2008, 06:26:12 pm
At the highest level of competition, which is the level that most of us are subjected to viewing, thanks to TV, you'll almost always see a deep squat under the bar, since this is the most efficient way to get under the weight.  But at regional meets, there is a great deal of power movements, since super deep squats simply aren't in the cards for everyone. 


Title: Re: Rules draft: weightlifting
Post by: kris on October 25, 2008, 08:03:18 pm
Having seen my share of frame-by-frame sequences of the Olympic lifts in MILO, I appreciate what Chip is saying above. When the weights are big enough, you won't be able to do much better than pull the bar to around chest height (give or take) and the only way of getting it overhead is to dip down deep under the bar to catch it overhead at whatever height you can get it to. Indeed, the picture captions in MILO never fail to mention how the lifter is "racing to get under the bar" showing the bar still going up and the lifter on his way down.

I find the rules for the Olympic lifts to be quite the contrast to those for powerlifting. In powerlifting, acceptable stance widths, arches, foot motion, bar placements etc. etc. need to be clearly defined to, among other things, enforce a certain minimum range of motion. Compared to that,  the rules of the snatch are basically just "fix the bar overhead with extended elbows and knees". The squat style is accepted as the most biomechanically efficient way of doing so and what I gather most weightlifters train for, but the rules do not actually mention anything about squatting down except for noting that you can bend your legs during the lift if you so wish. I'm guessing that it is common for beginning weightlifters to lift more without squatting deep as the squat introduces a huge skill and timing factor, but in the long run you have to learn to squat down to get the weights to an appreciable level.

If we were to only accept lifts where the lifter squats down, we would face the interesting problem of defining legal depth for the Olympic lifts. It would also break the basic idea of our rules being as close as possible to the real thing by creating our own representation of the lifts.

So, power snatches are certainly legal in our meets as they are also legal in real-world weightlifting meets.


Title: Re: Rules draft: weightlifting
Post by: mightykat on October 25, 2008, 08:27:28 pm
I understand and respect everything that's being said here. But personally, I don't want the amount of weight I power snatch to count the same as if I snatch. Lord knows, I'd fare so much better if I power snatched in a meet. I know how much simpler a power snatch is for me to perform, and how much more weight I can move. But if I couldn't respect my record that way.

To me, it would be like benching in powerlifting with the option not to have the bar come down to the chest, yet competing equally against lifters who are touching and pausing.

Would you consider different classes according to form, or perhaps there's a different formula for scoring the two?

I may be the only one who thinks this way, but I think it's a healthy discussion at any rate...


Title: Re: Rules draft: weightlifting
Post by: kris on October 25, 2008, 10:17:35 pm
Kat, I understand what you're saying and I don't think you are alone in feeling this way. In many ways, I think this is the same dilemma that many powerlifters, including myself, have wrestled with in regard to whether to use the maximum arch the rules allow or to retain a decent range of motion one can feel proud of when bench pressing. But ultimately they are still different as an elite weightlifter should be able to actually lift more using the "purist" approach whereas the small archer will generally always lift less. Weightlifting is a highly technique dependent sport and most serious weightlifters are likely to embrace that by learning how to squat down properly. In this sense, power snatching just doesn't cut it even if one could lift more that way.

I think your suggestion to have different formulas or classes make perfect sense in that regard. Indeed, for bench pressing we offer both regular meets and military bench meets where the arching is basically prohibited and the feet are required to be kept in the air at all times. But how this could be implemented in practice for the snatch and/or the clean and jerk is far from clear. Whereas military benching has a precedent, to my knowledge this hasn't.

As I wrote above, if we go down this road we need to clearly define at least legal depth (parallel as per the Wikipedia link Vadim mentioned above?) as just saying that a squat or split is required is too fuzzy for judging. If we were to do this it would have to be separate meets as coming up with a fair formula to compare snatches to power snatches is not a trivial task. The question is also whether there would be interest in these kinds of meets and whether they make long-term sense as most(?) serious weightlifters will probably attempt to squat under the bar regardless of which meet type they are in. This would also make the rankings rather interesting... I would be inclined to conclude that this would introduce needless complexity to the meets we are offering while not bringing in much more than an extra seal of approval for using classic technique.

Anyone have any thoughts or ideas in this regard?

This is indeed a very valuable discussion in that it helps put the finger on the fundamental questions at a very early stage where it is still easy to make changes.


Title: Re: Rules draft: weightlifting
Post by: Chip on October 26, 2008, 06:25:36 pm
Kat, although your power snatch is greater than your full, this will change.  Unlike squat depth, where a shallower squat will ensure more weight moved, Olympic lifts, with practice, become the opposite.  Depth technique will eventually create a scenario in which you can get under MORE weight faster, if you have the flexibility (the biggest inhibitor for depth for folks who have experience but still don't drop deep is simply the ability to squat deep).

The evolution of these lifts was, over time, finding the most effective technique for getting the largest amount of weight overhead quickly.  With that in mind, we can see where they are 'weight' lifts, not necessarily needing to be judged on pure beauty. My weightlifting team sometimes falls into the habit of arguing about perfect technique and how lifters should be judged on form.  To end the argument I just ask them to watch my lifts.  They ain't pretty, and they never will be, but they thankfully meet the current specifications for competition.  If grace were part of the equation, I'd have to look for a new sport.

Thanks everybody for joining this “panel”! You have dispelled my uncertainties as per Power/Full style variations full stop. You have helped me to make my goals and priorities much more articulated. :)
Because, at least for me, it was not a trivial question.
Well, absence of a platform at our gym is not a great deal of an issue for me any more. I now can approach my power snatch more confidently and, hopefully, try and see about this ½ discrepancy between my Snatch and C&J. No doubt, this sport is all about confidence. No more excuses for my waiving the Snatch.  8)  ;D

If the judging side of things is too messy, I would suggest that lifters at least try to do the classic lifts rather than the power versions where possible. At least we're all on the same page then!


Title: Re: Rules draft: weightlifting
Post by: kris on January 25, 2009, 09:21:55 pm
I think the judging side of things boils down to having good enough judges who know a good lift regardless of whether it is textbook style or not. I think most people who are serious about excelling in Olympic lifting will try to learn and perfect the textbook style early on which indeed may lead them to lift less weight in the beginning. But our aim is to stay as closely aligned as possible with the official rules of the sport and since they do allow the power versions we should too. This is a dilemma that is probably shared with many weightlifters out there, but it's probably not unique to the sport. In many cases, brute force will excel until technique is mastered.

But, as you Warren indicate, we can always say "hats off" for anyone who shows up with classic technique. But we must recognize that this is not something everyone can do, or even aspires to do. In a sense, it is also a good thing because it lowers the barrier to entering a meet and getting familiar with the sport, especially for us powerlifting types and people doing the weightlifts to support other sports. In the end, it is up to each and everyone to select their technique and it is our judges' job to make sure they all fall within the rules. Perhaps one day we can try a "classic meet" with stringent rules, but for now I see little point in being stricter than everyone else.

I guess the more people that participate in any way the better. As for long term interest in these kind of meets, they are the only reason I signed up! I've not much interest in powerlifting.

I think the site is a very original idea and I hope it goes far.


Title: Re: Rules draft: weightlifting
Post by: mightykat on May 18, 2009, 06:43:08 pm
I know a while back someone had suggested weightlifters be allowed the option of lifting in a singlet. Did anything ever come of that? I doubt it's negotiable, but for what it's worth, I think it would be hugely beneficial if we had the option.

Good question. Nothing final has been decided, but personally I am more in favor of not allowing them because it keeps the clothing rules uniform across both sports. If we allow singlets in weightlifting, we should probably also allow them in powerlifting, but as discussed earlier (http://virtualmeet.net/community/forum/technical-questions/45/msg267/#msg267) the situation is a bit tricky on that side of the fence. Most powerlifters also compete in singlets and/or supportive gear, so both groups are now in pretty much the same boat in that regard.

But arguments for and against are still very much welcome. Do you see any strong benefits for allowing singlets beyond being able to compete in the same gear as in a real meet (which *is* a very strong point in itself)?

The rules are begging for a series of small updates here and there, but we will roll with the current version until I have finally gotten version two of the site out the door. That is currently priority numero uno. :)


Title: Re: Rules draft: weightlifting
Post by: mightykat on May 19, 2009, 12:53:49 am
For me, the benefit is the fit of the cloth. It's tough to find something that allows the same freedom of movement in the shoulders if it's a t-shirt, and moreover, ensures modesty. I don't want my midriff exposed in a lift; it also keeps the female chest in check. Most women's t-shirts are made on the shorter length, so when paired with shorts, there's not much coverage to play with. And most men's are crewneck, so it gets bunchy around the shoulders and neck when the arms are overhead.

Although I do feel strongly about this, I will say - I am really finicky about clothes and how they fit - so maybe someone will tell me I'm a bit overboard here? I'm curious how other weightlifters feel about it.

Title: Re: Rules draft: weightlifting

Remind me again - what are the weightlifting team rules?

They are not formulated yet, hope you didn't spend a lot of time looking for them... The main reason for this is that version 2, which will make it possible to form teams, is still in the oven. I had rather hoped to release it just about now, but the fact of the matter is there is still some work to be done. I'd prefer to work out the exact rules against the backdrop of actually being able to form teams; but as the first team competition is now only a few months away (April) it is high time for a heads-up. Thanks for asking for one. :)

The most important point is that team competitions will NOT be separate events. Perhaps a summed up relative strength adjusted total for the X best scoring lifters for each team. This would produce a team score that could then be used to compare teams against each other and to create a team ranking. This is pretty much the same thing as how team competitions are held in at least powerlifting, but with relative strength scores instead of points by placement in each lifter's bodyweight class (under IPF rules (http://www.powerlifting-ipf.com/fileadmin/data/Technical_Rules/IPF_rulebook_05_2009.pdf), a first place in a class gives 9 points, second place 8 points... all the way down to 2 points for 9th place, all subsequent places give 1 point; these are then summed up for the 6 best lifters for each team to produce team results; draws are settled by comparing which team has the most first places). 

If we do this, then the main questions to settle is how many lifters that should be counted towards the team score (3? 6?), whether to also allow teams with less than that amount to compete in the team competitions even while thus handicapped and whether to only count team points if a team explicitly wants to take part in the team competitions (this would seem fair).

As I wrote before (http://virtualmeet.net/community/forum/meet-talk/332/msg2423/#msg2423), I don't expect that there will be many teams ready by the April weightlifting meet, but this meet will mark the beginning of when teams will start to get noted for their participation and can start collecting team points. What it evolves into after that remains to be seen. :)

Did that clarify it a bit, or do you have any further questions or thoughts? As usual, I'm all ears.


Title: Re: Rules draft: weightlifting
Post by: warren on February 03, 2010, 11:47:33 am
If there is a team meet, do the individual scores still count towards the individual rankings? For example, say I hit a couple of PBs in the team meet, will my page/personal ranking be updated too? Or are the team meets separate leaderboards?

Yes, absolutely. Everyone who competes does so individually. If you happen to belong to a team and have enough of your team mates in the same meet to qualify for team points, then your best individual scores will be aggregated to reach a team score in addition to your individual scores. So your personal bests would be recorded as usual in the personal rankings and the team score goes into a separate team ranking.

This is roughly the same concept as the Nation ranking following the Olympics ("country X came into first place by grabbing 6 gold medals, 4 silver medals and 12 bronze medals").
