Objective of the study is to develop a formalised model of swimming technique efficiency based on anthropometric factors, strength, power and kinematic characteristics of young swimmers.
Methods and structure of the study. 24 young male swimmers aged 12.5±0.9 years with 3.5 years of competitive swimming experience who regularly participate in regional competitions took part in the study. The factor model of swimming technique efficiency was developed taking into account current data on the factors that determine the performance of young swimmers at the training stage of preparation.
Results and conclusions. The factor model of swimming technique efficiency includes variables of general strength, hydrodynamic power and kinematic efficiency of the stroke, which explain 68.7% of the performance of young swimmers.

Keywords: young swimmers, anthropometry, hydrodynamic power, kinematic indicators, performance.
