Objective of the study was to develop a criterion for assessing the stability of technique based on analysis of the intercycle force variability of highly qualified rowers.
Methods and structure of the study. To analyze the intercycle force variability, a competitive exercise was simulated by covering a distance of 2000 m in laboratory conditions on a Concept-2 rowing ergometer. The study involved 8 highly qualified rowers with a body length of 188,37±6,25 cm and a body weight of 85,96±8,66 kg. During the study, specialized software was used to save dynamometer charts directly during work, using the built-in measuring module of the ergometer. Using mathematical modeling methods, a parameter to quantitatively reflects the variability of force between cycles was developed.
Results and conclusions. As part of the study, a criterion that reflects the variability of force between rowing cycles on an ergometer was developed. The obtained results show that this parameter allows quantitatively assessing the degree of stability or variability of the applied force in each stroke cycle. Data analysis confirmed that high variability of force may indicate insufficient technical preparedness of an athlete or his fatigue, while low variability is typical for more familiar modes of work of rowers with a stable motor stereotype. The developed parameter can be useful for monitoring the training process, identifying areas for technical improvement and assessing the technical preparedness of athletes. Further research can be aimed at integrating it into biomechanical analysis systems for improving and controlling technique in cyclic sports.

Keywords: rowing, evaluation of force variability, biomechanical analysis, efficiency, movement technique.
