Introduction. Despite the apparent simplicity of the technical execution of the deadlift and the relatively small amplitude of movement, errors that appear during the learning stage can contribute to negative consequences, in particular, spinal injuries, sprains and ruptures of the ligamentous-articular apparatus, adverse changes in the functioning of the trainee's systems and organs, reduced physical fitness, and decreased performance.

Objective of the study. To experimentally substantiate a methodological approach to teaching students the deadlift technique based on conscious self-control and intermuscular coordination of motor actions.

Methodology and organization of the study. The research involved 1st-3rd year students (EG, n=10; CG, n=10) from Perm State Pharmaceutical Academy and Perm State Humanitarian Pedagogical University, enrolled in the elective course "Powerlifting." Mastering the deadlift technique included learning special preparatory exercises similar in technical structure to the competitive movement – lifting a bodybar, barbells from stands of different heights (with gradual lowering of the stands), as well as performing the lift using different techniques ("sumo," "conventional deadlift," "mixed"). During the learning of exercises, attention was focused on conscious control of muscle sensations [1]. Analysis of the types of technical execution of the deadlift allowed the development of a "basic" technique structure (7 control points and 3 phases) and an assessment scale.

Results of the study and discussion. A comparative analysis of the deadlift execution technique (instructor's assessment, assessment by fellow students, self-assessment) indicates significant differences (p<0.05 according to the White T-test) in the indicators of the EG and CG. The increase in the EG was 35.765% (before the experiment, the level was below average (3.3±0.48 points); after – high (5.83±0.39)), while in the CG it was 27.72% (before the experiment – below average (2.82±0.75); after – average (4.16±0.84 points)).

Conclusions. As a result of the conducted research, an improvement in the technical preparedness of students in the experimental group when performing the deadlift was revealed. This methodological approach contributes to effective learning of exercise technique, the formation of the ability to perform movements consciously and correct them independently, which allows preventing injuries to the musculoskeletal system, diseases of organs and body systems, and improving physical fitness and performance.
