We will introduce the differences in the way advanced and beginner jumpers use their hands and feet in "ayatori" (string figures).
We will introduce examples of the use of the "Markerless 3D Motion Measurement System" for advanced and beginner jump rope practitioners. We focused on measuring the Y-coordinate of the LeftFoot to observe the jumping technique and the X-coordinate of the LeftForceArm to analyze hand movements. As a result, it was found that beginners have unstable jumping power, resulting in a pointed shape, while advanced practitioners have stable jumping power, resulting in a rounded shape. 【Case Study】 ■ Movements of LeftFoot and LeftForceArm - Beginners: Jumping power is unstable, resulting in a pointed shape. - Advanced practitioners: Jumping power is stable, resulting in a rounded shape. ■ Timing of arm opening and jumping - Beginners: The timing of arm opening and the interval between jumps are shorter. - Advanced practitioners: The timing of arm opening and the interval between jumps are consistent. *For more details, please refer to the PDF document or feel free to contact us.
