Ando's was ratified by the ISU [...]
Not sure if there are in-vivo studies concerning increased tendon sport injury risk accounting for natural hydration methods but here are two articles demonstrating biomechanical correlations with tendon fiber hydration. They demonstrate loss of flexibility and lubrication (among other things) which I believe are scientifically supported as correlated with tendon injury risk (but I could be wrong! I am lazy to check...)Frankly I never heard about this. I read about dehydration in connection with muscle cramps, but not influencing tendons.
Ah actually I hear this all the time from Grishin. If a girl got taller over the off-season or hit puberty and has a disaster skate, he always mentions that we should appreciate the skater and we have lots of hope for them to get used to their new body, and its ok that they are having trouble while adjusting. In fact we get at least a few comments like that from him per event. Though on the other hand people like Tarasova will publicly reprimand any girl who gained a couple pounds, on live commentary in front of the whole world, which is insufferable.I never heard any commentator commenting on fall or mistake with: "...but you know, they are going through body changes, so it is remarkable that they are able to keep the level high and land this and that."
Hm, thats a little subjective about what exactly is post-puberty since we are only judging visually. You are right I can not think of any 20 year olds who jump fully rotated quads. Kamila for example though was obviously post-puberty by visual judgement when landing clean 4Ts. Not sure about other examples honestly. Its definitely true that small junior girls are taking the lead in quads, their bodies do allow for the rotations much easier. We'll see for example if grown up Akateva regains her 4T or 4S this season. Petrosian has a perfect 4T I think she'll keep it, dont know about the 4F. Hard to tell where she is in development though, from what I understand her entire family is very short so I dont think her growth is stunted. Anyways these are just additional comments, I understand the issue with quads, I am not really trying to debate your thesis on that.And all other FULLY ROTATED quad jumps were / are executed on junior or novice stage. By girls with prepubertal body. Or by girls with postponed puberty (Sasha Trusova and Anna Shcherbakova at the Olympics 2022).
The ISU has gone through a lot of contortions and hand-wringings over this question. It seems like every couple of years they tweak the scoring rules rules about q, <, <<. etc.Well, the question is what counts as "fully rotated"
Ando's was ratified by the ISU under the 6.0 standards of the time but would not have been under IJS.
Thank you for your comments but I think in the view of the information we have seen so far here on many other skaters, it rather deserves praising him that he's been working with a nutritionist at all, which is not common among skaters, as we all know, (BTW he just said in the interview aired this weekend that he was 17, not 18, when he first started, after all) Still Yuzu also said what I think very important - that it was pretty new and uncommon when he first started, at least in his "circles", and that it is getting more popular among athletes now.
Yes, he, or anyone else, could have benefited more if started earlier. Still he benefited a lot, even starting at this old age of 17-18 which I think deserves to be the point of focus here and not be easily dismissed. So I'd rather say it was lucky and wise that he did start at all although it was not really common in his environment, than choose to ask "why so late".
Sure, I agree parents and skaters should be encouraged to work with professional nutritionists as early as possible. Still, this knowledge should be passed on to them first and foremost by the coaches, and also by medical professionals, sport doctors, physiotherapists, or even GPs when they learn a kid is practising some sport. Nobody is born with such knowledge. If a 17 year old skater is not aware of the potential benefits he or she might get from the nutritional help, it is not his or her fault, or his or her parents' fault. It is the fault of the whole sporting environment, - the coach, the club, but also the sporting community at large, the federation, ISU - as they seemingly neglect training, information and communication on things that matter. Maybe, just maybe, because they are not properly educated themselves, on nutrition, but also on communication.
So, if some skaters happen not to be enlightened as to the need to consult a nutritionist when really young, and they happen to get the knowledge and be initiated at a bit older age, I think they should still be encouraged and praised when they do it at a later stage. They should be told "it is great, it is never too late, it can still help you achieve great things, look how it helped Yuzuru Hanyu, even though he started late" and not be dismissed as starting too late .
I also think it is important to promote this knowledge with some positive examples, as positive as they are out there. It has long been proven by huge volume of research that concentrating only on negative information does not really help much in achieving a change in behaviour patterns or spreading information. Quite to the contrary, it is contrasting the negative with showing positive ways to go and positive examples which really helps.
And BTW, it is interesting. Yuzu started working with a nutritionist when he moved to Canada to be coached by Brian Orser, although the nutritionist himself was based in Japan. So did Zhenya Medvedeva, at a similar age, alas with much damaged body and stress fractures already there, who also explained she had never ever been informed earlier about the possibility and importance of getting nutritional help. I wonder, is it possible that it was not just a coincidence but that it is a positive influence of TCC which we know of as a great coaching environment in many other ways, too. If true, this would be truly great and a model to follow. ...
...
But isn't the new age threshold to move to seniors trying to address exactly this, among other things? Maybe there should be some more definite shift of focus for junior skaters to allow them an easier passage through puberty changes but just the fact that their results, and therefore any potential setbacks or failures, do not count towards their senior careers yet is probably some kind of relief, or at least it should be? I know it does not work everywhere the way it should, is far from perfect, in fact, but wouldn't you see it as a step in a desirable direction? What would you think an appropriate age for them to move to seniors?

Heres an article on hydration and tendon development/nanostructure. I think they mention its related to recovery and injury. This article could be irrelevant TBH I barely skimmed the abstract haha but I am adding it just in case. The earlier two articles though I am pretty sure are relevant.
It seems that the literature is pretty quiet on this topic under the specific experimental conditions you have in mind. But its also a difficult thing to study in-vivo and probably not much financial incentive from hydration supplement companies on tendon-specific issue since the general public doesnt think about those things.
However I think those first two articles support the thesis well. I admit though this is far from my area of knowledge. I am not a life scientist, and if I am in any way knowledgable on life sciences its about genetics and perhaps some micro-processes. Macro life sciences are the furthest thing from my expertise, at least in a peer-reviewed technical sense.
But I also find it anecdotally supported from my personal experience, that athletes suffer tendon related muscle detachments under dehydrated states such as resulting from martial art weight cuts for example. Actually powerlifting/bodybuilding/strongman probably provide the best anecdotal evidence in regards to pectoral tendon detachment, quadricep/hamstring detachment, plus bicep/tricep detachment under dehydrated weight-cut conditions. Its a very common occurrence and hydration is a well accepted factor by coaches and athletes in those sports. I think there is a lot of truth outside peer-review and a lot of falsity and monetarily-inspired deception in peer-review as well. Especially true for subjective and popular subjects like sports science. Though I understand the interest in peer-review sources and will generally fold to those requests. I am a little surprised you "never" heard of a correlation between hydration and tendon ruptures if you are involved with sports and athletes, but if you are not involved with them but only study the literature then I understand.

Would it make sense to say that women who land quads with < or q calls (but not <<) can be considered to have landed quads in competition, i.e., to have accomplished an impressive jumping feat, even if not quite with as much rotation as the good male jumpers or best young teen girl jumpers can manage?
No, Trusova was not the first to land a quad successfully. That honor goes to Japan's Miki Ando. 2002.
Quad Salchow is at 1:50.

TV commentators may not say it on the air (it would be rude and embarrassing to the skater, who is probably uncomfortably self-conscious anyway), but I do think that there is a lot of gossipy talk in skating circles along the lines of, “Oh no, she filled out. Now she’ll lose her jumps.”
...
I do know about both Miki Ando and Surya Bonaly, not to forget Sasha Cohen in 2001.
But I meant FULLY ROTATED quad jump.
No, ability to land quads is not restricted to the prepubertal period, and as you note there are more adult/senior men landing quads than junior men competitors in their teens landing quads.Looking at men cathegory - both boys and mature men, both tall and short, both muscular and thin skaters can land quad jumps, it is not restricted to one body type or prepubertal period.
It's this mental aspect, I believe, that is the hardest to deal with.- ...After losing again to Lipinski at an Olympic-style competition earlier this month [in 1997] in Hamilton, Ontario, Kwan said: ''In practice, sometimes I'd be a little off. I always worry: 'What's wrong with me? I can't do this.
Age | Attempts | Fully rotated | GOE+/clean |

I came across this old interview with Akiko Suzuki. I remember you have quoted her once or twice in one of your compilation posts, but this interview is basically all about her eating disorder and healing., She is very frank and it is very candid, and I think everyone should really read it.
Akiko's story is also a success story as she developed her ED between her junior and senior careers, had to take time off skating at all to heal and also because she was just too weak to skate, but came back and actually had her biggest successes, medalling in senior competitions and participating in two Olympics as a part of Team Japan after her ED and healing which I think really important to showcase. As heartbreaking as it is, it is also a story of hope.
She also believes her experience with ED and openness to talk about it is an important factor sometimes in her work with young skaters. Although she is a choreographer now and not exactly a coach, they find her much easier to approach and talk to about their problems, knowing she went through ED which is public knowledge in Japan by now. Tough but very precious reading. I really respect her so much!
And here's the link to Akiko's bio for those who are not familiar with her career, to give some context to the story.
Akiko Suzuki - Wikipedia

Sasha Cohen landed nothing in competition. Neither did Bonaly.
"Bonaly says she landed most of the quadruple jumps—the Salchow, toe loop, flip, and Lutz—in practice, but was never able to cleanly complete the four rotations in a competition.
A fully validated quad at a women’s skating event didn’t happen until 2002 when Miki Ando of Japan successfully executed a quadruple salchow at the Junior Grand Prix Final. Ando tried to land the first quad at an Olympics, in 2006 but fell and only received credit for a triple.
U.S. figure skater Sasha Cohen landed a few tightly executed quads in practice at an event in 2001, but not during the competition. It wasn’t until 2018 that Russian teen Alexandra Trusova, then 13, again landed a quadruple in competition—the quad toe loop, at the Junior Grand Prix Lithuania. U.S. figure skater Alysa Liu became the first American woman to land a quad in competition in 2019, at a Junior Grand Prix event. Liu has since grown several inches taller, which has affected her jumping, and she did not include a quad jump in her free program this season."

Landing the quad successfully in competition is what counts. Not practice. The reason I put the word "again" in bold is many years passed before another woman would match what Ando already accomplished.
It's this mental aspect, I believe, that is the hardest to deal with.

No, ability to land quads is not restricted to the prepubertal period, and as you note there are more adult/senior men landing quads than junior men competitors in their teens landing quads.
However, it is not true that any male skater with any genetic predisposition to any body type will be able to land quads when he reaches senior level.
Some men may have a typical body size and shape for elite skaters, but they don't have enough fast-twitch muscles or other muscle fiber composition characteristics to be able to develop enough strength and quickness to jump high enough and/or rotate quickly enough to jump quads.
Some will grow up to be extremely tall and long-legged, or significantly heavier than the skaters who are successfully landing quad. Just look at athletes in other sports, who have maximized their training to excel in those particular sports, but who also are blessed with body types that favor those sports.
Can you picture a typical pro basketball player or American football player etc. landing quads even if he had trained in figure skating rather than basketball or football from childhood?
The pool of male figure skaters is comparatively small. But within that pool, there will be boys who are successful up to junior level in their teens. But they will struggle to master triple axels and quads because their bodies will not grow to be optimized for those jumps. So either they will quit competitive skating entirely, or they may transition into pairs or dance where their skating skill will be valued without the need to rotate those difficult jumps.
And because the pool of male skaters is smaller in most countries, a larger percentage of these young men will have opportunities to have senior-level skating careers in one discipline or another. But many of them will never land quads.
Which is different from being able to land the quads as teens and then losing that ability as adults. I don't know offhand of examples of that happening. If it has, it has probably been more because of injury than because of body type per se.
But I have heard of boys who had triples and then grew too big to maintain those jumps as consistently as when they were small. For the most part, they won't make it to senior level at all.

However, even with the pre-teens and early teenagers, you have to remember that they can be in very different stages of development - some are early, some are late. Plus changes do happen also even in late teens and early 20s. ...
Should I or should I not? Ok, let's go...
So @sisinka is right about quad attempts and age. There are right now 1223 attempts by women since 1990 and 396 have been fully rotated and 293 have a positive GOE or have been otherwise deemed clean (ie Miki Ando 2002). And 99 skaters (oooh, I so hope the 100th will appear soon enough!).
I plotted the attempts according to age and, indeed, preteens and early teens have done most of them (this calculation does not include a couple of girls whose year of birth is unknown):
Age Attempts Fully rotated GOE+/clean 9-14 880 396 293 15-16 216 119 93 17-19 76 25 22 20-23 23 1 1
Majority of the currently active skaters are in the novice/jr groups, so it remains to be seen what will happen in a couple of years when they start growing up. The ones in the late teens/early 20s group with GOE+ jumps are Tursynbaeva, Kihira, Shcherbakova, Trusova, Sumiyoshi and from today also Petrosyan. And as is well-known, Sumiyoshi is the only 20-year-old (though I still say that jump was very generously gifted to her by the tech panel).
However, even with the pre-teens and early teenagers, you have to remember that they can be in very different stages of development - some are early, some are late. Plus changes do happen also even in late teens and early 20s. There is very little data on even height because majority of them have never competed internationally in juniors when their ISU bios would reveal sth. (Though even that is not very reliable since they're not always updated regularly.) But just based on how the quads seem to disappear after 16, it seems that most adult women are really not able to do them. With 3As, the situation is much better, but that's another story.
Men have done most of the 18300 quads I have in my database and there's a lot more data on height, for example, it is perhaps possible to say a little bit more. The age when they start to attempt quads has dropped quite a lot:
21,5 years in the 1980s
20 in the 1990s and 2000s
19 in the early 2010s
17,5 in the late 2010s
16,5 in the early 2020s
When it comes to growing up, this means that more and more pre-puberty/pre-growthspurt boys are attempting quads when before they were mostly already close to or at adult height. However, the problem is that most of the young quadsters are Russians and there is no data for height. So, it's going to be difficult to trace how particularly growing height might give them problems with quads.
There are some cases, though, but those cannot be generalized. The most famous one is perhaps Stephen Gogolev who started attempting quads in domestic comps when he was 12 (2017) - don't know how tall he was then, but in 2018-19 when he went to international juniors, he was 154 cm. Then in the following seasons 162 cm, 174 cm, 179 cm, 183 cm until he reached his current height of 185 cm (ISU data). Though he did not have a huge growth spurt, gaining 20-25 cm in a couple years plus having injuries must have thrown his jumping off. He reportedly landed all but 4A in practice as a junior, but these days has mostly 4T and 4S with not great consistency.
More recently, a Swedish skater Casper Johansson started attempting 4S in comps when he was 14 and he was a tallish boy at 172 cm. Since 2020 he has gotten to 188 cm and has also had some injuries I think. He is still attempting 4S and is adding 4T. His record is not great, but it could be that growing height was also a problem and he has had trouble developing the jumps further.
Think also of Roman Sadovsky and Artem Kovalev, who were tiny juniors and now very tall seniors (in the 180s). Both have 4S, Artem also 4T, but again struggling with them. Nikolaj Memola is by far the tallest man ever to get a clean quad at 195 cm, but he is not very consistent with his 4Lz.
Some of the best quadsters ever based on quantity and quality, Chen, Hanyu, Fernandez, all started jumping them when they were already very close to their adult height. Hanyu and Fernandez match the average height for quadsters at 173 cm. Chen is a little smaller. Ilia Malinin is of similar size also, but grew up fast between 2019-20 and 2020-21 (154 to 170 cm). He started to attempt quads in comps when he was 170 cm already. So, height is maybe a factor since the very tall guys are not so very good at it.
Body type is harder to study - male figure skaters tend to be pretty slender, but looking at Elvis Stojko and thinking of his jumping brilliance, it is obvious that a muscular body is not an obstacle. Similar guys maybe Stephan Lindemann, Alexander Majorov off the top of my head, maybe even Adam Siao Him Fa. However, particularly these days when a certain amount of flexibility is necessary even for men, too much muscle is not good. (I remember Javier Fernandez saying that he had to keep away from the gym because he would have gained a lot of muscle easily and it was not good for the overall performance.)
These are just some randon thoughts. It is difficult to build any kind of significant database based on what is available, these are all just anecdotal cases and nothing can be said in general based them. Could be that better data would show my current assumptions completely wrong.
