Objective of the study was to assessment of the snatch technique of the strongest weightlifters of the Russian Federation during competitions using an integrative approach.
Methods and structure of the study. Bilateral video filming was carried out with Cannon-EOS90D cameras during the All-Russian Spartakiad in summer sports among the strongest athletes of 2022 in weightlifting. Based on the data obtained, kinematic and dynamic indicators of the movement of the barbell CM were determined.
Results and conclusions. It has been shown that athletes with a technique above the average level lift the barbell "up and back" along an S-shaped trajectory that does not intersect the vertical line drawn at the moment the barbell leaves the platform. These athletes begin the final acceleration phase when the barbell's CM is at a higher relative height. Athletes with a higher level of technical efficiency lift the barbell to a lower relative maximum height and with a lower maximum vertical velocity, i.e. they perform the exercise more economically. More technical athletes have smaller losses of the barbell's CM vertical velocity in the transition phase.

Keywords: weightlifting, integrative approach, biomechanical control.
