Objective of the study was to identify the characteristics of the physical fitness of yachtsmen specializing in the “RS:X” and “IQF” classes.
Methods and structure of the study. Athletes of I-II categories who have been involved in sailing for 4-6 years took part in the scientific analysis. To determine the level of development of physical qualities, testing was carried out on 22 male athletes aged 15-17 years, 14 of whom compete in the “RS:X” class and 8 in the “IQF” class. The testing program included specialized tests for assessing sports readiness.
Results and conclusions. In a scientific analysis of the level of physical fitness of athletes specializing in the “RS:X” and “IQF” classes, no significant differences in indicators of shoulder girdle strength were identified. Speed-strength, speed and strength indicators of the development of the lower extremities in athletes from the “IQF” class turned out to be significantly higher than in representatives of the “RS:X” class. Tests for assessing the level of preparedness of athletes, proposed by the Federal Standard of Sports Training for the sport “sailing”, do not sufficiently reflect the level of physical fitness of athletes specializing in the discipline “Sailboard”. The study revealed differences in the results of athletes specializing in the “RS:X” and “IQF” classes in the following exercises: standing long jump, jumping rope, “chair” exercise, which are advisable to use to control the level of physical fitness yachtsmen of the above classes.

Keywords: physical fitness, yachtsmen, RS classes:X and IQF, sports analysis, age groups, testing program, physical fitness indicators, speed and strength qualities, Federal standard of sports training, sailing, RS:X class, IQF class.
