Only thing we can do is wait and see whether the 3A will keep their ultra-c elements after puberty. Because if they do, that means indeed the beginning of the new era in the womens figure skating as it was 5 years ago with Yuzuru Hanyu to pushing men doing more than just one or two quads.
Unfortunately, in such periods, there will be always some that were unfortunate to be competitive elite athletes with the 3A , but as it seems, even in Japan and America, they are preparing their athletes with these prospects of quadruples and 3axels. Nobody says that this has to stop, you cannot stop the sport from going forward. Rafael and coaches of adult women, have made some conclusions based on their own athletes who are post-puberty , so there is no reason that we do not believe them. If it was easy for Medvedeva to learn a 4S at this age ( despite being in great shape last few months), she would do. It takes time that women now may cannot afford it ( especially for Russian ladies ). A youngster learns easier these jumps ( not only from physical point of you but from mental point , too). Yep, it is cruel indeed. But in what cost?
The reason that people have concerns is not because they have favorites. I love Anyas expression more than Zagitovas for example. It is because,IMO, there is a certain frequency in which they tend to retire after 2-3 years. Do they burn out too quickly? Can all the 3A withstand the amount of training that they are doing right now for more than 2-3 years? Is it only about motivation or the body cannot do anymore ( as Medvedevas showed us leaving the group? ) ? Being a medical student myself, i can tell , that the body has limits. So you go beyond them in order to win everything in 2 years and be in the world records and thats it ? I think that we need time to see all of these, because it is only 5 years that Russian figure skating in womens category has brought such a development.
What i do not understand, is why, sometimes, there is heavy criticism to these people that have concerns about age limits and whether the sport is becoming too technical. It is not like we do not love the sport,oh, we do!! And we do love really much all these girls and that is why you are trying to protect each one of them. For them it is their lives, we are just spectators. You cannot just say to someone, hey, i know it is your whole life, but a 15year old is bringing me medals, so go away. Lot of people just adore Tukts skating so much, and not only cause of 3axes in such an age... personally, i can relate with her because i am same age. And i want to relate. It is sport and art , afterall. I see myself in her and get really happy after watching her skate. Life is not only about winning all the time, why should sports be that? Just a thought...
