Abstract
It was found that qualified female weightlifters have errors in the technique of performing competitive exercises, which are manifested due to deficiencies in the development of motor skills, the inability of athletes to rationally use inertial forces, which are also influenced by their constitutional features. Despite some works that study the features of the technique of performing competitive exercises by female weightlifters, this area of scientific research remains insufficiently studied. The goal is to analyze the effectiveness clean and jerk among qualified weightlifters of various weight groups. Material and methods. Theoretical analysis and synthesis, pedagogical observation, biomechanical video-computer analysis, methods of mathematical statistics. Using the “Weightlifting analyzer 3.0” (Germany), the biomechanical characteristics of the rod movement structure were determined. Analyzed 282 competitive attempts in the clean and jerk, 96 qualified athletes from 16 to 20 years, different groups of bodyweight categories (weight classes). An analysis of the competitive activities of qualified athletes showed that 45.0% of competitive attempts were unsuccessful. The analysis revealed the causes of unsuccessful attempts and errors, repeated by athletes at the competition in the push of clean and jerk and second methods of the exercise. As a result of the counting, it was found that due to errors in the first intake of a push, 32.3% were unsuccessful in the second intake - 67.7% of cases. Analysis of the errors in lifting the barbell from the chest by athletes of different groups of weight categories indicates that the characteristic of violations has a different direction in the structure of the movement of the projectile and varies depending on the morphological differences of weightlifters, skills that they have mastered during the training process. The greatest number of violations in the technique of the clean and jerk female weightlifters of three groups of weight categories (from 33.0 to 47.0% of cases) in violation of the kinematic structure of the movement of the projectile, which indicates the relevance and necessity of studying the causes that lead to this.
