The discussion shouldn’t be whether it is possible to land triples or quads if you are higher than average weight for a figure skater, but what’s the long term impact on your health, especially your knees and hips. If landing a jump means impact on your joints that is four times of your weight (and that’s when the jump is landed well, if it is not landed well, it is six times of your weight!), imagine how bad for your joints is any extra kilo you may have. An elite skater would do numerous jumps every day in practice, and not all of them will be landed well.
I am not promoting bullying anyone to lose weight, or anyone being ‘pushed’ into eating disorders, but there is a reason why the sport promotes slimmer skaters. The reason is not aesthetic, and it is not that it would be impossible to land the jumps while being heavier. The reason is that being slimmer is less damaging to the skater’s body.
I seriously doubt that. Being too thin can cause bones to become thin and brittle. Didn't Satoko Miyahara have to take time off because of concern about her bones being brittle? She was advised to gain weight and she did. And we aren't talking about skaters being overweight. Tonya Harding wasn't overweight. The issue is expecting skaters of normal or even already slender builds to lose weight. Should Tonya have lost weight when she was already a good jumper? As far as I can recall, her career problems were never because of injury.
