Objective of the study was to develop and experimentally substantiate a methodology for developing hand strength in young wrestlers based on the use of a set of special exercises performed on a training device with a closed biokinematic chain of hands.
Methods and structure of the study. On the basis of two sports schools - the city of Shuya and the city of Ivanovo, Ivanovo Region - in the period from 2017 to 2021, a study was conducted of 86 SAMBO practitioners. The total population of the surveyed sample of children is 12-13 years old.
In the course of the work, an analysis of scientific papers on the research problem was carried out. The degree of development of the absolute strength of the hands was assessed using dynamometry, speed-strength abilities were determined when climbing a rope to a height of 5 m, strength endurance - by the duration of the hang on the crossbar. The reliability of the grips for the jacket was determined by an expert assessment. Processing of the received data using the Microsoft Office Excel 2007 software package.
Results and conclusions. Developed on the basis of the results of the study, the methodology for developing hand strength in young wrestlers is built on the use of a set of exercises using a special training device "Wanderer". The effectiveness of the application of the methodology is confirmed by the results of the pedagogical experiment. For sambists from the EG, the average values ​​of the results for all tests at the end of the pedagogical experiment are significantly higher than for young athletes from the CG (p<0.05). The use of special exercises in the annual training cycle of young wrestlers, performed with a closed biokinematic chain of hands on the training device "Wanderer", allows to increase the degree of hand strength development and the efficiency of grips in the process of fighting.

Keywords: young wrestlers 12-13 years old, hand strength, biokinematic chain.
