The Morisue skill (Double Salto Tucked to Upper Arm Hang) on parallel bars is recognized as a high-difficulty element in men’s artistic gymnastics, demanding precise coordination, momentum control, and technical mastery. Despite its complexity and recent reclassification as an E-difficulty element in the 2025–2028 FIG Code of Points, limited biomechanical research has analyzed its execution, particularly within Arab and international contexts. This biomechanical case study aimed to investigate the kinematic and kinetic characteristics of the Morisue skill, based on the performance of an elite German national gymnast preparing for the 2024 World Championships in Cairo. Two-dimensional motion analysis was conducted using SkillSpector software (version 1.3.2) on video recordings captured at 30 frames per second. Key parameters—including displacement, velocity, acceleration, angular momentum, and force estimations—were extracted to characterize performance phases. Temporal analysis revealed that the preparatory swing phase accounted for 47% of the total execution time (1.76 seconds), highlighting its critical role in energy generation. Peak angular velocity during the second salto reached 768°/s, while the maximum center of mass height achieved was 56 cm above the bars. Although the limitations of 2D analysis and standard frame rate restrict the precision of kinetic calculations, the findings offer valuable preliminary insights into performance optimization for high-difficulty elements. Integrating biomechanical feedback based on such analyses can enhance training strategies, particularly regarding release mechanics, dynamic balance, and tucking efficiency. This study provides a scientific foundation for coaches and athletes seeking to refine technique and improve competitive outcomes in elite gymnastics.
