“…Earlier works by Popel 'et al, [2,3] have shown that athletes after competitions have an accumulation of acidic metabolites in peripheral blood, especially lactate. In this case, the shift of the pH towards the acid reaction (up to 7.26) occurs due to the activation of the synthesis of 2,3-DFG.…”

“…In a number of studies [2,3,11] it was shown that when practicing strength sports, special requirements are made to the functional reserves of the athlete's cardio-respiratory system. This immediately affects the functional state of the peripheral circulation and is often associated with the level of erythrocyte hemostasis.…”

“…The athletes of the main group also significantly differed in the indicator of the state of the venous outflow, which was significantly higher than in the control group. It is well known that the flow of blood from the bottom up provides a number of factors, the most important of which is muscle contraction during exercise [2]. Apparently, prolonged static loads (weight lifting), periodic and longterm tension of the muscles of the lower extremities creates an obstacle to the normal outflow of venous blood.…”

“…Erythrocytes preparations were prepared according to generally accepted rules [2,3,10]. and examined in a JEOL-25A-T3225 scanning electron microscope (Japan), and the percentage composition of different types of red blood cells was determined using the computer program "Biovision-4.01" (USA).…”

“…The problem of developing a recreational regime in the physical training of athletes in power triathlon is still far from a final solution [1]. There are practically no scientific studies in this area and the role of the erythrocyte hemostasis system after physical exertion remains undisclosed [2,3]. There are only some fundamental data in the study of the problem of the manifestation of strength and strength training in weightlifting [4][5][6] and the associated changes in capillary blood flow in the lower limbs.…”

Objective: The aim of the work is to study the features of peripheral hemodynamics of individual segments of the lower limb in athletes involved in power triathlon at rest. Method: Rheovasographic methods and electron microscopy of red blood cells were used to study the regional blood flow. Results: The study of regional blood circulation features according to the rheovasogram data in the "hip", "leg" and "foot" areas and the structure of peripheral blood erythrocytes showed that changes in the lower extremity vessels in athletes involved in power triathlon indicate an adverse reaction to intense physical activity, which depends on the level of skill of athletes and the segment of the lower limb, and on the morphofunctional characteristics of peripheral blood erythrocytes.

The study aimed to determine the suitability of testing the saliva of kickboxing athletes to show changes in biochemical parameters in dynamic of training. 8 elite male athletes (mean age 17.29± 0.31 years, body mass 66.82± 3.46kg, with 5.62±0.96 years of training experience) participated in the study. Indicators of lipid peroxidation and glycolysis (the concentration of lactic acid and pyruvic acid) were defined before and after a training session. Significant increases in indicators of lipid peroxidation activity indicators and the concentration of lactic acid (4-fold) were observed; analysis of correlation matrices confirms the absence of expressed changes. At the same time, significant decreases in catalase (10-fold from 3.69 μkat/L to 0.39 μkat/L) and pyruvic acid (from 3.92 μl/l to 0.55 μl/l) were observed. Our results confirm the value of using saliva to determine training load in an individual. Moreover, the study provided information on the importance of indexes reflecting a correlation of various biochemical indicators to estimate the sufficiency of training loads. The ease of sampling and informational content of saliva are reasons to use such tests in monitoring athletes' functional state to prevent fatigue.

The problem of structural changes in peripheral blood erythrocytes in patients with chronic heart failure in combination with vitamin D deficiency during exercise stress remains insufficiently studied. Vitamin receptors are located on smooth myocytes, endothelial cells, cardiomyocytes and blood cells. It affects the state of the cell membrane, the contractile function of the myocardium, the regulation of blood pressure, cardiac remodeling and reduction of left ventricular hypertrophy. Therefore, it is important to assess the level of vitamin D in blood plasma in individuals with chronic heart failure and to identify the effect of its deficiency on the state of peripheral red blood cells when performing a 6-minute walk test. A total of 75 patients of the main group with chronic heart failure stage II A, I–II functional class with different levels of vitamin D deficiency were examined. The control group included 25 patients with chronic heart failure stage II A, functional class I–II without signs of vitamin D deficiency. The average age of patients was 57.5 ± 7.5 years. All patients were asked to undergo the 6 minutes walking test. The level of total vitamin D in plasma was determined by enzyme immunoassay. Morphological studies of erythrocytes were performed on the light-optical and electron-microscopic level. The obtained results showed that patients of the main group with chronic heart failure had a decrease in vitamin D by 2.2 times compared with the control group. Correlation analysis showed a directly proportional relationship between vitamin D deficiency and the number of red blood cells of a modified form and red blood cells with low osmotic resistance. Dosed exercise stress in patients with chronic heart failure against a background of vitamin D deficiency leads to an increase in the number of reversibly and irreversibly deformed erythrocytes and a decrease in their osmotic stability. This indicates a disorder in the structural integrity of their membrane and can have negative consequences for the somatic health of such patients.
