Annotation:

The research purpose – is a comparative study of biomechanical characteristics of a ski jump and simulation exercises of ski jumpers.

Methods and organization of the research: measurement of support reaction force during take-off in ski jumping and simulation exercises using the F-scan in-shoe pedograph; video analysis in the Dartfish Pro program. 

Results and discussion. Significant differences were identified in the indicators of force, time and angular values in simulation exercises and ski jumps. The data obtained indicate that the movement structure of young ski jumpers does not correspond to the modern requirements of ski jumping.

Conclusion. The technical features of the young ski-jumpers who took part in the study require correction of motor asymmetries in the technical and physical training of athletes.
