Comparative Analysis of Kinetics Parameters During Different Landing After Split Front Leaps

Abstract

Introduction. Dance and rhythmic gymnastics are high leap demanding sports. Leaps are fundamental human movements that require complex motor coordination of both the upper and lower body extremities. The aim of this study was to compare the kinetics parameters of two types of landing after performing front split leaps.Material and methods. Fifteen high-level acrobatic gymnasts with a mean age of 22 ± 2.76 years and mean training experience of 12.27 ± 2.34 years participated in the study. Examinations of kinetics parameters of the movements analysed were carried out using the Vicon system and Kistler plates. Gymnasts completed front split leaps with balanced landing (arabesque position) and moving landing (continued movement).Results. Values of vertical ground reaction force and values of muscle torque in the hip joint were statistically significant higher (p < 0.001) for balanced landing. The value of leg stiffness was also significantly (p < 0.001) higher for balanced landing (5.69 ± 2.45 kN/m) compared to moving landing (1.89 ± 0.43 kN/m). For balanced landing, the sequence of maximal peaks of torques from the highest to the lowest values were found in the hip (5.81 ± 1.06 Nm/kg), ankle (3.56 ± 0.71 Nm/kg), and knee (2.01 ± 0.75 Nm/kg) joints. For the split leap with moving landing, the most loaded joints, in descending order, were the ankle (3.50 ± 0.42 Nm/kg), hip (3.39 ± 0.78 Nm/kg), and knee (2.21 ± 0.57 Nm/kg) joints.Conclusions. The findings of the study can help to improve the methodology of training the technique and protect gymnasts and dancers against unnecessary injuries.

Application of multiple regression models in the analysis of kinematic parameters in competitive gymnastics

“…A kinematic technical model was established to test the kinematic characteristics of outstanding athletes completing the single-bar parallel-leg Makelov maneuver according to the part of gymnastic rules and sports biomechanics principles. In the literature [8], the kinematic analysis and study of the whole process of Du Wei's completing the vault side handspring straight side flip turn 990° movement was conducted by using the methods of 3D camera and analysis. In the literature [9], the kinematic biomechanical principles were used to analyze and study the movement of the hoop cross brace, and the electromyographic analysis method was used to analyze the characteristics of the muscle electrical signals of the hoop cross brace in combination with the technical essentials.…”
