Abstract

The aim of this research was to evaluate how well the MediaPipe performs in comparison to Kinovea in analyzing key kinematic parameters in the clean lift movement for physical education students, and how reliable the MediaPipe is in doing so. The research design used in this study was descriptive, combined with both comparative and correlational research approaches. The researchers recruited 30 first-year physical education students at the College of Physical Education and Sports Sciences and conducted an experiment on their clean lift movement, captured by high-speed cameras and analyzed using both the MediaPipe and Kinovea. The data analyzed included the knee, hip, and ankle joint angles, and barbell movement, such as vertical velocity, vertical displacement, and bar path. The data analysis involved the use of descriptive statistics, Pearson correlation, intraclass correlation, root mean square error, paired t-test, and Bland-Altman plots. The findings showed that the MediaPipe and Kinovea are highly comparable, particularly in analyzing the velocity of the barbell, where the correlation coefficient between the two tools was 0.96, showing high concurrent validity. There were no significant differences between the two methods. The reliability of the MediaPipe in analyzing the kinematics of the clean lift movement was high, as the correlation coefficient ranged between 0.85 and 0.91, showing high stability in the measurements. The analysis of the bar path movement showed high comparability between the two methods. The conclusion drawn from the research is that the MediaPipe is an effective and affordable tool for analyzing the kinematics of the clean lift movement and thus can be used in both educational and research settings.

Abstract

Background. Football is one of the most popular sports in the world in terms of the number of spectators and the level of physical and technical proficiency required. In football, the main objective is to score as many goals as possible during the game. Objectives. The study aims to explore the relationship between dynamic stability and shooting accuracy in stationary and moving conditions among advanced soccer players in the city of Samarra, Iraq. Method. This study used a descriptive-analytical method with a correlational design. The study consisted of 54 participants, chosen from premier football teams in Iraq. Two tests were conducted in the field to assess the accuracy of shooting in stationary and movement situations. Results. The study found that the accuracy of shooting in stationary situations is significantly higher than in movement situations. On the other hand, the study found that the accuracy of shooting is significantly influenced by knee angle, contact time, center of mass deviation, and trunk oscillation in both stationary and movement situations, whereas ankle angle and execution time are significantly influenced in movement situations only. The study also found that the proposed model is able to explain 58% and 64% of the total variance in shooting accuracy in stationary and movement situations, respectively, using multiple regression analysis, whereas the results showed statistically significant differences in favor of stationary shooting using repeated-measure ANOVA. Conclusion. The study concluded that the accuracy of shooting is significantly influenced by dynamic balance, and this is an important factor in the accuracy of shooting in soccer games. In addition, the study also found that the use of Kenova software in the Iraqi sports arena is effective in producing reliable results, which can be used by coaches in improving the accuracy of shooting in soccer players.
