Influence of Hip and Shoulder Angular Velocity on the Execution Phase of the Upstart in Men's Artistic Gymnastics

The sport of men's artistic gymnastics (MAG) demands extraordinary strength, timing, coordination, and technical accuracy, particularly when performing apparatus-based routines. One of the six MAG devices, the horizontal bar, requires athletes to execute intricate swinging and acrobatic movements while maintaining constant body control and momentum management. (Rathore & Chandel, 2023) A fundamental ability that moves the gymnast from a hanging posture to a support position on the bar is the upstart movement. During routines, it is essential not only as a fundamental movement but also as a prelude to or link between more complex abilities (Atiković, 2020).
