Analysis of the spatio-temporal characteristics of the jerk of bar of weight-lifters of high qualification
The analysis was made of the spatio-temporal characteristics of jerk of highly qualified weightlifters. To find the characteristics of the barbell movement, there were used high-speed video recording of the jerk. When analyzing the technique, the exercise microstructure proposed by the authors was used, which includes, among other things, phases lasting less than 0.04 s. Using correlation analysis revealed group dependencies between the studied indicators. Indicators are identified that differ significantly in successful and unsuccessful competitive attempts of the jerk. An example of the analysis of the individual technique of the jerk according to spatio-temporal indicators is presented.
