    What I have heard is that it is the base mark of the element as called by the tech panel plus/minus the average GOE of judges' scores as soon as at least three of them have entered GOEs for that element.

    There might be some change to the average GOE at the end of the program when the rest of the judges' scores are added in. But if there's a big change, that would probably because the tech panel reviewed the element after the program was over and changed the call (for one or more elements).

    Hi! I'm a relatively new fs fan (riding that post-Olympic wave yo \m/) and had a question concerning jumps.

    I really like Yulia and her skating, but while watching worlds I noticed her jumps were rather low compared to other skaters', and after spending some time on the forums learned this could be a concern for her rotations if she grows a lot during puberty. I was wondering if someone could explain why her jumps are so low. Is it something based on training/technique or is jump height dependent on a physical variable like height (I initially thought jump height was based on a skater's height, but Anna P. is only an inch taller than Yulia and gets more height...) or weight?

    I think it's a combination of

    anatomy: muscle fiber type composition (percentage of fast-twitch vs. slow-twitch fibers), strength-to-weight ratio,
    leg length

    and technique: knee bend, timing, use of the edges (and toe picks on toe jumps), use of the upper body to generate lift and rotation, etc.

    Whatever the skater's maximum possible jump height is based on genetics and training, they can still choose to use different techniques to jump as high as possible or as far as possible and vary them depending on what they're doing next -- e.g., in jump combinations especially triple-triples, the advice is to aim for distance rather than height on the first jump, for maximum speed going into the second jump

    And all skaters are likely to jump less high later in the program when their muscles are fatigued.

    The effect that puberty has on jumping, primarily for girls, is mainly the decrease in strength-to-weight ratio.
    Also as women's bodies become larger and more curvy, rotation isn't as efficient, so modest jump height that was sufficient for quick rotation with a small straight body type is not enough for a larger curvier body.

    Some girls can improve their jump height as they mature through developing their muscle strength and technique. But not all body types will allow for enough improvement to compensate for natural increases in non-muscle weight and in less aerodynamic body shapes.

    There are a lot of skaters who can't jump high enough to rotate triples at all. But we usually don't see them at the elite levels (except in ice dance)

    That is quite interesting, to say the least. Thank you, gkelly.

    A nice film by NSF about the physics of jumps and spins
    https://www.nsf.gov/news/special_rep...ureskating.jsp

    The scientific paper resulting from this research
    http://iceskatingresources.org/Triple&QuadJumps.html

    A really nice work up by an engineer who is a Yu Na Kim fan

    The research paper has training recommendations which include more focus on proper exercises for the arms. I found it very interesting. Btw,Mishin wrote a famous book on the biomechanics of jumps-some coaches get very, very technical. Others not so much.

    for lack of better phrasing

    how do female skaters keep their underwear from stretching or moving to avoid er, ungainly insights into their land of treasures? do they have special underwear? is it made of special fabric? do they need to get fitted for it? is there a secret anti-camel toe device sewn inside?

    (i better not get an infraction for this question, i'm about to be banned as it is and the thread title says 'stupid questions' so you asked for it)
