FACTOR ANALYSIS OF BARBELL JERK PERFORMED BY SKILLED WEIGHTLIFTERS DURING COMPETITION
Abstract
Aim. To carry out factor analysis of barbell jerk per for med by skilled weightlifters during competition. Research organization and methods. Weightlifters’ skill perfection is associated with using the various modern instrumental techniques of objective control necessary for obtaining the exact quantitative characteristics of biomechanical structure of the athletes’ moving actions at competitive exercising. To record the trajectory of the barbell movement and dynamic indicators we used a specialized software and hardware complex including photo-video camera, transmitting source installed at the end of the barbell and the appropriate software. The study involved highly skilled athletes (n = 13), the members of Kazakh national weightlifting scratch team (8 men and 5 women). Results. The analysis of obtained empiric data revealed intra-group regularities of kinematic and dynamic parameters of the barbell movement during the jerk, and also revealed the factors influencing the motor action efficiency. Conclusion. The program and techniques of barbell jerk enhancement for high-skilled weight lifters should be developed considering the motor action efficiency factors revealed by the research. It will enhance the quality of educational process aimed to improve the weight lifters’ sports mastery.References
