Yuma Kagiyama (JPN), an Olympic silver medalist from the 2022 games, claimed an impressive victory with a significant lead of over 30 points, leaving his competitors far behind at Shanghai's ISU Four Continents Figure Skating Championships. This triumph marks Kagiyama's first-ever ISU Championship title.
He also attempted his first quad flip but was not successful.
Perform'Live designed an advanced stromotion to get a global view of the jump. That's the signature of Arnaud Muccini. Let's have a deep look.
In the picture, we put some markers to understand the complexity of the figure skating jump.
Point 1: How we approach and enter jumps is significant. It has a profound impact on the quality of our preparation and, thus, plays a critical role in determining the success of our jumps.
Point 2: There's a noticeable issue with the positioning of the upper body; it is leaned excessively forward. This posture can potentially hinder body weight transfer in the air, negatively affecting overall performance.
Point 3: During takeoff, the body axis forms an angle roughly around 20 degrees. Aiming for an angle within the 13- to 15-degree range would be more optimal and efficient. This slight adjustment could significantly affect the overall execution and performance.
Point 4: By the end stage of the flight, there's an observation that the body posture is too upright. Such a stiff and erect posture may lead to Yuma stepping out, which we must avoid for better control and balance.
The data are good. The flight time is huge (0.720s), and the angular velocity of his snap ( 24.933rad/s) is good as his rotation is complete.
We can notice that he landed on his toe-pock and stayed on it, trying to regain his balance.
The height and the length ( approximation data, we used 160cm as it's written in his ISU bio).
Anyway, If we apply the Projectile motion formula, the length of his jump should be longer, showing the ineffectiveness of his draw ( Part from the toe-pick till the take-off)
Here is a little reminder of this projectile motion formula ( Simplified).
Plane or two-dimensional motion encompasses various forms, such as circular and projectile motion. In analyzing these forms, notably projectile motion, the reference point is determined by an origin and two coordinate axes, X and Y. A prime illustration of plane motion is projectile motion.
In the meticulously detailed, slow-motion footage captured by the broadcasting team, we are given an unparalleled view of the nuanced quality of the toe-pick. From this perspective, we can distinguish that it engages in a motion of actual movement rather than a mere pivot. This subtle but significant detail is a testament to the skill involved.
