Lactate contents in the blood of highly qualified football players during the pre-competition period

Relevance. In the realm of elite sports, the necessity for a straightforward, lucid, and dependable assessment of adaptive resources and mechanisms cannot be overstated. Given the prevalence of near maximum loads in athletic endeavors, there exists a propensity for athletes to teeter on the brink of overtraining. The body, being a single whole, responds to any impact, including physical activity, with a set of changes in its indicators. Fundamental research in the field of sports biochemistry carried out in recent decades, and, in particular, on changes in carbohydrate, fat, and protein metabolism under the influence of various sports activities, has made it possible to widely use the parameters of energy metabolism in sports practice. Lactate analysis is a reliable tool for monitoring the training process since changes in lactate levels reflect the intensity of physical activity and the body's adaptation to stress.

The purpose of the study was to study the lactate content in the blood of highly qualified football players in the pre-competitive period. The work consists of optimizing the training process to achieve high results in competitions.

Methods. The content of lactate in the blood of highly qualified football players in the pre-competition period is being studied, which indicates the importance of this parameter in assessing their physical fitness before competitions. Lactate analysis is an important part of monitoring the training process and allows you to optimize it to achieve the highest results in competitions. To conduct blood lactate testing, a portable lactate analyzer Lactate Plus (Sports) was used.

Conclusions. Optimization of the training process provides coaches and medical personnel with information about the reaction of football player's bodies to training loads in the pre-competition period and helps adapt training programs to the individual needs of each athlete.
