الملخص EN

The research aims to build a hierarchical model of selective differentiation of biomechanical variables through the following purposes : 1.

filtering biomechanical dimensions using factor analysis.

2.

using hierarchical differentiation analysis to build a model between the levels of players to identify the factors affecting each level (distinct-less distinguished ).

the research sample was selected in a deliberate way and numbered (2) players from the upper levels in fencing, where their ages are from 23 : 17 years in the weapon club, and the research sample was divided into two groups (distinguished-less distinguished).

from the reality of the data and within the limits of the selected research sample and the method of imaging and kinetic analysis followed, it was possible to extract (14) variables representing the qualitative groups of mechanical variables and these extracted factors are characterized by a high ability to explain the variation between the variables, where a pyramid model of selective differentiation and filtering of biomechanical dimensions using factor analysis to identify the factors affecting each level (distinct-less distinguished) using the ecclesiastical selective discriminatory model (aggregation) of the final model, which showed the ability to classify to a high degree depending on the variables that were reached through the model with a coefficient of validity of 92.0%, and the results also showed the existence of a correlation between the variables of the model using heat maps where two gathering areas with high correlations appeared.

there searcher recommends 1.

BAttention to the study of the analysis of hierarchical differentiation to identify the factors affecting the level of skill performance and take advantage of its potential in scientific research.

2.

implementing a cooperation protocol between the faculties of physical education and the various clubs and facilitating the subjection of high-level players to study and analysis
