הנה הסבר קצת יותר מלומד
מצאתי טור שמדבר על זה. פחות או יותר כתובים הדברים שאתם אמרתם, אם כי ההתייחסות היא לטכניקה שלה בלבד ולא לנתונים הגופניים (מורפולוגיים) שדווקא אליהם נכנסתם לא מעט. ברור לי שיש לה תכונות כלשהן שמקלות עליה (ולו במקצת), אך כאן הן לא מוזכרות. הוא מזכיר את מהירות ההרצה אבל מתמקד בעיקר בזווית הפגיעה. אם הבנתי נכון, הוא אומר שדווקא זווית חדה יותר עם השולחן טובה יותר ליציאה למעלה (תקנו אותי אם הפכתי בטעות את הדברים!).
הנה עיקרי הדברים:
Yet many may wonder how it is that McKayla Maroney can perform the exact same vault so much better than anyone else. What is it that makes hers different?
One aspect that is necessary for any vaulter to perform well, especially those at the highest level, is speed into the board. And from what I can tell, McKayla has loads of it coming into her Yurchenko piece of the vault . She actually builds speed through her run, starting out more relaxed and gradually accelerating as she continues down the runway.
However, this is a common trait that all top vaulters have. As a spectator miles away, I can’t really tell how fast she is, or even if she has the fastest sprint speed into the vault of all the vaulters. But, to do what she does, she still has to be fast. Without excellent speed into the board, everything else is irrelevant.
The second aspect of her vault is likely, what I would call, the separation factor. When I first saw her vault, and noticed how difficult it was for the camera technician to keep her in view as she popped off the vault table like she was shot out of a cannon, I knew what I wanted to look for in the slow motion replay NBC normally shows after a good performance. And sure enough, I was not disappointed.
If you watch closely during MaKayla’s Amanar vault, you will notice that her hands hit the vault with her body at a steeper angle (body more down toward the spring board) than do many of her other competitors. Most of them have their bodies higher on the vault as their hands make contact with it. What this does is effectively allow her to take that speed she generated in her run and redirect it up, “blocking” herself into the stratosphere.
Next, and simultaneously with her block, she explodes using her arms and shoulders (which is all supported by a very strong core), exponentially adding to her quest for “flight.”
Last, this blocking motion detailed above also contains the “snap” down, where Maroney’s explosive push is combined with a pull down of her body in order to generate the rotation she needs to complete the vault. So as her shoulders and center of gravity continue upward (that “pop” you see as she comes off the vault table, the piece the camera technician has trouble staying with), her legs, feet and part of her core rotate downward.
From here the major pieces of what separates her from every other vaulter out there is pretty much completed. Now it is all about twisting mechanics and sticking the landing. The height and distance has already been determined by these initial parts discussed above...
זה לא מחדש הרבה, אבל כתוב בבהירות ונראה שהכותב יודע על מה הוא מדבר.
