Objective of the study was to develop a methodology for calculating the projections on the frontal plane of the horizontal components of the biomechanical characteristics of the movement of an athlete and the barbell when lifting the barbell to the chest.
Methods and structure of the study. High-speed shooting (250 fps) of lifting the barbell to the chest with one camera was used. Lifting the barbell 180 kg to the chest was performed by a master of sports.
Results and conclusions. The proposed method makes it possible to calculate the horizontal components of the movements of the athlete and the barbell, as well as to find the horizontal components of the forces applied by the athlete to the barbell when lifting the barbell to the chest, and the angular velocities of the body turns.

Keywords: chest lift, phase structure, technique analysis, spatio-temporal, kinematic and dynamic characteristics, high-speed video filming.
