Abstract:
This study aimed to propose specific alignment of body segments, and Center of Gravity
(CG) movement pattern of the gymnast who is executing the “Kolyvanov” dismount on
the Pommel Horse (PH). Further, this study provides specific criteria about accurate
alignment of body segments throughout the dismount to reduce the common errors. The
national gymnasts (n=3; height=1.64±0.05 m; weight=52.23±3.04 kg; age=20.33±2.52
years) who are eligible to perform this element were taken for this study. The data were
collected by using six high-speed cameras set up (Miqus M3; 100Hz; 64Ö41◦) to capture
the “Kolyvanov” movement pattern. The collected data were analyzed through the
human movement analyzing software (Qualisys and Kinovea 0.9.5). A three-dimensional
graph of CG movement pattern was designed according to the standards of the Men’s
Artistic Gymnastics Code of Points (2022-2024). The biomechanical model was defined
by displacement of the CG on the Cartesian coordinates system using three dynamic
equations of motion. Moreover, the major six positions of the “Kolyvanov” were described
from eighteen equations of motion. The height of the gymnast and body segment
angles aligned during the positions are the variables, which define corresponding to the
coordinates in the model. Based on the biomechanical model, elite gymnasts can predict
the correct CG movement pattern of the dismount. Therefore, the optimum alignments
of body segments will be a factor to minimize execution errors and energy extinction.
Hence, gymnasts can acquire the “Kolyvanov” dismount artistically by practicing fewer
repetitions.
