New study on the effects of Rollkur .....

from TOB:

This is the link to the original version (in German). http://www.dressur-studien.de/

A very popular German horse magazine will be publishing a more detailed article on this study next week.

A newly developed endoscope makes it possible to monitor the respiratory system of horses in movement which so far has only been possible if the horse was standing still. Researchers from the Graf-Lehndorff Institute have been able to investigate the impact of Rollkur on horses. For this study, they longed 16 horses: first with long side reins, then with extremely short ones so that the horses had to move in Rollkur position.
Results: because of the ‘rolled up’ neck the horses had problems breathing, the respiratory tracks narrowed, the pulse rate increased. A thermo graphical camera, which was used at the same time as the endoscope, researchers also showed that Rollkur horses tensed up, the blood circulation changed, and horses hollowed their backs. All in all the head of the Graf-Lehndorff-Institute, Professor Christian Aurich, concludes that Rollkur leads to an “unphysiological strain which should have no place in any training of horses”.

can someone translate the german if there is more than what is posted above?

many thanks.

What does anyone think of this?

It says Cavallo did the study on 16 horses. Cavallo the equipment/clothing company?

The commentary (‘no place’) is from the chief of the count Lehndorff institute, professor Christine Aurich.

Is a very short side rein while longeing (I presume a ‘position naive’ horse), similar enough to hyperflexion to make a good test, or no?

Is the presence of an endoscope creating its own effects, or does it not alter the effect of the position of the neck?

Were the horses unfit babies that had never had their necks positioned? Horses with unsuitable necks for upper level dressage? Would either make a difference to how you felt about the study?

Is the difference in measurements significant? Is it enough of a difference that it is larger than the margin of error for the instrument?

Did they measure the difference between numbers for hyperflexion and numbers for a classical dressage position, poll highest, nose near the vertical?

Does anyone feel they need to compare the two?

I think that’s the first thing hyperflexion proponents will insist the study lacks.

Did they find a point at which the breathing starts to be affected? Are some slightly deep positions not altering the numbers?

Does anyone think this is just German vs. Dutch again?

If it is a good test and a good measurement and significant, this result will be sufficient to force the FEI to remove it from the warmup rings, or they would be facing actionability for allowing abuse. If the study is validated, I’m thinking any number of situations would provide an opening for a lawsuit against the FEI.

If validated, this would also be sufficient to prevent a lot of people from using it - or permitting it to be allowed on their horses.

How can anybody compare a rider to side reins? Side reins are static whereas a rider’s hands give and take.

And slc brings up a good point… the measuring device itself most likely contributed to the problem.

What a silly piece of paper!

P.S.: Dressur Studien.de is the german version of sustainable dressage, another hyped up, hysteria-based, shlock site.

Does anyone think this is just German vs. Dutch at this point?

Yes, there is that possibility.:cool:

The only sure thing is that this study won’t end the debate.

Siegi, I’m not so sure it’s entirely silly. Even if it is, there are a lot of people that are going to think it isn’t silly.

I’ve got another question.

Where exactly is the constriction? Because in fact, it could pertain to many other types of riding as well.

I think we all agree that Scandic was ridden in hyperflexion in the video.

No matter how long or short the tongue part really was, one thing should be clear by now:
Scandic WAS NOT GASPING FOR AIR.

ergo, I accept that as proof that the endoscope study above is about as relevant as the usual blind men describing the elephant.

You know it’s so amazing that you post all these demanding questions here - the man’s name is provided - CALL HIM UP and ask him.

Challenging any attempt to evaluate this method of riding doesn’t make any sense.

Years ago no one thought about the impact on the bones of young racing horses. As technology permitted MIT worked on a study that put pads on the horse’s feet and they were able to calculate the impact on the bone as the horse’s foot hit the ground. More often than not it was higher than the amount necessary to cause injury. The study also showed that often the weather, footing conditions, horse’s individual physiology on that day was the only factors that kept the horse from fracturing. As technology has improved more of these studies have been done.

I commend these people if they are at least making an effort to make some study on rolkur. The issues raised in your questions may or may not be valid but I’m sure they can continue on this track and continue to improve the technology to assure the results are valid.

And Seigi - it would be wonderful to believe your statement about riders hands not being static (though side reins with elastic or rubber doughnuts are not static either- we should find out what type they used), but the reality of today’s riding is the riders are NOT giving and taking - happens alot at all levels. Spend time on the rail at any dressage show or watch the videos - face riding is quite common.

Canyon Oak - I totally disagree with you - I did NOT see a relaxed stallion. And not to get into an arm wrestling match but blind people can often giver more detailed descriptions of things if they can touch them than people with sight.

I realise this is Epona and some might regard this as controversial (and most have likely already read it in their research?), but I felt they gave a relatively good report here (?), with the use of numerous studies:

http://epona.tv/uk/news/show/artikel/rollkur-roundup-fact-and-fiction/?tx_ttnews[backPid]=388&cHash=d507652d15

They seem to provide a rather un-biased article (mostly) that even highlights the possible innefectiveness of some of these studies, such as the one mentioned by the OP, where the horse is on a treadmill and/or not ridden by a rider, where side reins or draw reins are used. I like that they seemed to critique studies on both sides, and they brought some important aspects to light.

My personal conclusion is that the true effects of Rolkur, as used for an extended period of time, is not yet known. It seems sufficient evidence to either prove or disprove the effectiveness or possible damage is not yet available. On the other hand, there is a lot of food for thought to consider in regards to how Rolkur works and its effects on a horse, both when used ‘correctly’, or ‘incorrectly’. I felt Epona said it best:
“So who should get the benefit of the doubt? The riders or the horses? The Code of Conduct of the FEI states very clearly that the welfare of the horse must be paramount at all times…” If in doubt (and we all are, sufficient research by professionals and vets, to indicate the harm or benefits of Rolkur has yet to be completed), maybe we do not do it, in the better interests of the horse. This is not to say to not use it for a stride or two, because althought studies have yet to prove the effectiveness, such a technique used for say a stride or two is obviously likely to not cause any ill effects. To use it for an extended period of time though - such an exaggerated frame, perhaps might not be the wisest idea though. Not everyone at the GP level is doing it or has done it.
With that, I have more studies to peruse, as well as to finish my read of ‘Tug of War’ :smiley:

ETA: One of the points that hit me was that in Rolkur if the horse’s frontol portion of the back is raised (T10) but the Lumbar spine (L5) is hollowed, as studies seem to suggest, would that not result in tension and a lack of collection, despite the feeling of throughness? In the trot, studies seem to indicate that the portion of the back is dropped directly under the rider as well as behind the saddle. Would that not result in tension in the back as the horse compensates for the weight of the rider (and due to the horse’s defensive mechanisms)? If that were the case, then the actual results would seem to be the complete opposite of the entire purpose of Rolkur - to increase motility in the back.

Last point was that, even here, there seems to be a vast array in ‘reasons’ as to why Rolkur is used. This seems to echo also into the upper echelons of dressage, including GP-level riders.
“Even Sjef Janssen admits that the technique is used for “dominant” horses, which infers horses with a tendency to display violent conflict behaviour. As a horse in rollkur can’t see where it’s going, it is possibly easier to control. And as behavioural zoologist and FEI trainer Dr. Andrew McLean pointed out during the Lausanne workshop: “… cervical flexion as a result of sustained bit pressure has a lot more to do with compliance and pain avoidance than suppleness…””
Others tout the ‘official reason’ for the use of Rolkur as being a form of gymnastics, to strengthen the horse and increase back motility.

So, which is it??

Has anyone stood beside a warm up of hyperflexed horses? Hear any breathing of the soft exhalations where the nostrils virbrate? Look at the surface veins of those same horses?

ise, all these ‘demanding questions’ are just musing out loud. why put such a negative connotation on it. whenever i read any study, i always think it brings up more questions than it answers. this one is no different.

ideayoda, are you saying horses in hyperflexion have their veins sticking out more, and make louder breathing sounds?

when would you compare them to a non hyperflexed performance? in the ring? aren’t they working harder in the ring than warmup?

MBM,

This is not from TOB, this is copied from Topdressage via UDBB to this forum.

So say thanks to Theo (me) who did the digging and translations for you and your friends !

I hope you understand that the study is not finished yet, and the conclussion are made by a German journalist.

Um, yeah pretty much any horse working hard for a sustained amount of time is breathing louder and has veins visable, so I have noticed…

Are we going to outlaw that too? Sorry to be obvious, but the Grand Prix is hard work. They are not going to be not stressed and comfortable the entire road there. If you never stress the horse physically, you’re not going to improve the fitness & suppleness of the horse, period. Such is the life of an athletic horse.

I have not done a scientific study, but it’s reasonable to expect that when a horse is in a compressed/collection frame, there is less room at times for the throat & airways, therefore breathing can become labored. Now, hopefully as the horse gets fitter, this is less obvious and the breathing isn’t as labored.

I am not pro-Rollkur, but some of these studies trying to demonize it are silly!

Of course breathing will be laboured with increased workload, however it seems that is not the argument at hand. The argument is that the airways of a horse in a Rolkur frame for an extended period of time is going to be more restricted than that of a horse in a collected frame where the poll is highest and the horse is at or in front of the vertical. Whether or not that is the case, I suppose we will have to see further research, but the horse’s conformation and structure describe it to be a distinct possibility.

Sticking an endoscope in your throat doesn’t seem very comfortable to me.

While I understand your point, I wonder if that is a valid assessment? Individual conformation and such is going to dictate the sound and volume of exhalations as well as the absence or presence of surface veins. I think a more accurate assessment would be to use such a study as the one above, but refine it to decrease error (ie. one such ‘refinement’ could be to have the horses under-saddle, and use international-level horses trained in RK, riding in a RK frame during the study (by their regular riders or someone of equal expertise) and same-caliber horses not trained in RK as controls, being ridden in a non-RK frame).

Though I doubt the validity of such an assessment anyways, even if you were to perform such a study, why would you ever compare ring versus warm-up performance? Of course their workload is likely to be different. Logic. Why could you not compare warm-up versus warm-up? Surely these riders are not holding their horses in such a frame, beneficial or not, for the warm-up in its entirety?

Okay, but what if you could have such a study and it without a doubt showed that rollkur ridden horses breathed more laborously (is that even a word)? What does that prove? That the horse is stressed? That the rollkur horse is working harder than it’s so called classical counterpart?

Really, what does that prove? I think if we establish that hard work for the horse equals awful, cruel things, then you should have a problem with FEI dressage in general. It is not a walk in the park for even talented horses!

In the training program of the horse, it is challenged (or you could also say physically stressed) at times to improve the horse - suppleness and fitness.

I don’t think there will every be a study that is able to come up with the unbiased answers. Bottom line - everyone will just have to use their own judgement and decide what is best for them and their horse!

It would prove that the airways of horses placed in a Rolkur frame are restricted. Hardly a good thing (would you like your breathing restricted and then have someone ask you to perform? It could hardly be considered comfortable), yet on the other hand, it would have to be taken into account with other facts. It would possibly allow re-evaluation of an extreme position, when used extensively (if not used for extensive periods of time, it would be likely doubtful that it would be overly strenuous on the horse). Workload of a Rolkur versus Classical horse would hardly be defined by restriction of airways. That would obviously involve another study altogether.

Really, what does that prove? I think if we establish that hard work for the horse equals awful, cruel things, then you should have a problem with FEI dressage in general. It is not a walk in the park for even talented horses!

Look, I am not condemning Rolkur here, just playing Devil’s Advocate. Do not twist my words, I never in a million years said that ‘hard work for the horse equals awful, cruel things’ - my own horses work very hard.

I don’t think there will every be a study that is able to come up with the unbiased answers.

Why not? Why can we not conduct peer-reviewed, in-depth studies as the technology and knowledge becomes available?

What is best for ‘them’ is not what is always best for the horse…hence the need for further research and knowledge.

There was a photo on eurodressage a few years ago, of a horse’s neck and shoulder area. Dark, near-black horse, veins sticking out like a road map through the sheen of sweat. The caption said something along the lines of how this horse was famous for its veins popping up like this during work.

http://www.eurodressage.com/reports/shows/2000/00bh/special.html

That was the lovely Westphalian mare, Renaissance, ridden by Monica Theodorescu.

Veins, breathing, terror, dullness,deadness, labor,welfare…

Humans see what they want to see, ascribe what they want to ascribe, believe what they want to believe. ANd honestly, I do not expect to change anyone’s mind here. I do not need the fingers of one hand to count the number of people whose minds are not firmly made up as to Yes/No on this question, despite the demurrals to the opposite.

Any decent animal behaviorist will explain the ‘posture of submission’ which is generally a lowered head. Anyone who works with horses teaches them to lower their heads.

When does the posture affect mental focus as well as physical suppleness? I do not know exactly. But do I believe it affects it,yes sure.
Rollkur can be used for this.

If I want to work ligaments and muscles, for sure I am going to work the longissimus dorsi that run from ears to tail and on which I basically sit.
If I want to keep my horse sound, I will use different frames/exercises/etc to work different parts of the horse’s body so biomechanically he stays as developed as possible.

That means hyperflexion,as this is a tool for most modern sport training,human and now horse.

So rollkur is useful for that.

No one keeps a horse in rollkur on a constant basis. No one keeps a horse up all the time.No one keeps a horse in any one single frame all the time if they are trying to gymnasticize.
No one wins with a truly unhappy or fearful horse, at least not for very long.
No one wins on a slave, at least not for very long.

Anky and Sjef gave the use of their horses several years ago,and various studies were carried out and found no evidence of damage. Of course, ‘damage’ vs. what is ‘normal’ changes according to the technology at hand.

There is a recent study of warmblood foals which found that ALL the foals in the study had fractures in their coffin bones from the age of a few months onwards.
Time will tell, but common sense suggests that foals have been fracturing and remodeling their feet for time immemorial ,only humans had no way to know it until now.

How can anyone know what damage has been done to the horses all these years we have ridden them? It was only a little while ago that researchers finally decided that there were a lot more back problems in horses than had been previously believed to be possible.

There was a time when people sat BACK on the horse over jumps–and these horses lived long lives despite all that!

Rollkur is a technique for riders who have mastered a lot of the foundation for riding, it is not meant for the average rider .
Just because someone asks a horse behind the vertical does not = rollkur.

Just because someone uses rollkur does not mean much unless they already have good control of the hind legs, can sit effectively, can do half-halt forward and in general have a strong foundation. Etc,etc.

It would be nice if the horses could go to max effort and never boil over. it would be nice if the riders could remain so contained and cool that no outside stimuli make them over-react.

It would be lovely if the (extremely) thin veneer of training we put on the horses took precedence over their prey-creature flight mentality at all times.

For me, when I look at some of the instances that are touted as examples of the above-- Absent piaffing for all he is worth while the paper blows; the apocryphal French officer who told his horse to Jump! and it jumped over the cliff with him; a lot of the work in pillars-- I just shrug and say, “boys with their toys” and do not find any of it positive or encouraging or reassuring.

For me, watching some of the top sport horses around now is far more compelling and satisfying.

But that does not mean that all of top sport is wonderful, just as the examples above do not mean that there are not many wonderful moments from classical.

I can still raise the hair on my arms thinking about two completely different experiences watching Georg Theodorescu ride. In each case, he performed a near-miracle and it was a privilege to be present .

So for me, there will continue to be only good riding and bad riding.

Good rollkur and bad rollkur.
Good shoulder-in and bad shoulder-in.
Balance, rhythm and harmony or … not.
