The result of performance at the most significant starts of the season in cyclic sports, including biathlon, is largely determined by the level of functional readiness of the athlete, which can be assessed using clinical and laboratory diagnostic parameters. Purpose of the study: to study the relationship between the effectiveness of competitive activity and indicators of the biochemical status of highly qualified biathletes. The study carried out a comparative analysis of the biochemical blood parameters of athletes with varying levels of competitive success at the 2023 Russian Biathlon Championships. It was revealed that athletes who did not achieve high results differed from the group of winners in high hematocrit, reduced levels of urea and creatine phosphokinase, inadequately high levels of cortisol, and they were also distinguished by reduced coefficients of damage and fatigue. It has been suggested that these changes indicate under-recovery and, possibly, a state of overtraining in the athletes. The discovered differences between the comparison groups can be used as criteria for the readiness of biathletes to participate in competitions.
