Objective of the study was to assess the impact of sambo classes on the physical condition of young athletes in the dynamics of the initial training stage.
Methods and structure of the study. The experiment involved children aged 10.9±0.59 years (initial training stage 1st year, 50 people), 11.6±0.6 (initial training stage 2nd year, 50 people) and 12.5± 0.75 years (initial training stage 3rd year, 50 people). The children were assessed physical condition and physical performance. The body mass index (BMI) and pulse arterial pressure were calculated. The results were processed using the STATISTICA 11.0 software package. The significance level was taken as p≤0.05–0.001.
Results and conclusions. The results of the assessment of the physical condition of young athletes involved in sambo indicate the peculiarities of the selection of children in sambo - short, strong build. In the dynamics of 3 years of sports training, there was an increase in the functional reserves of the cardiorespiratory system and the preservation of its adaptive resources in a state of relative muscle rest. Young sambists have improved speed-strength characteristics and power potential of the muscles of the upper shoulder girdle, articular flexibility, but there is a slight increase in speed, coordination, flexibility and performance of the heart muscle. Therefore, at this stage of training, it is necessary to increase the volume of training sessions aimed at developing endurance, speed and agility.

Keywords: initial training stage, young athletes, sambo, physical condition.
