[The features of cardio-respiratory system and autonomic regulation in parasportsmen with spinal injury].

A comprehensive study of the functional state of basketball athletes in wheelchairs with spinal cord injuries in the T6-T10 and paraplegia (n = 9, mean age 26.6 +/- 1.7 years) was held. As a control, we used disability groups with a similar injury, leading an active life (n = 13, mean age 44.5 +/- 2.6 years), athletes ( = 14, mean age 24.6 +/- 1.3 years) and healthy physically active men (n = 15, the average age of 24.9 +/- 0.6 years). In the athletes in wheelchairs it was revealed an increase in the length of the body in a sitting position, the increase in tidal volume and increasing in the effectiveness of the functional respiratory tests. These changes in the state of the musculoskeletal system and autonomic systems to ensure physical activity classified as adaptive and due to sports training. In the state of the cardiovascular system and its autonomic regulation parasportsmen showed a reduction in trauma-induced increase in diastolic blood pressure and increase in the magnitude of arterial baroreflex sensitivity, decreased due to spinal injury. These data indicate availability of compensatory processes aimed at optimizing the cardiovascular system through the mechanisms of baroreflex regulation.

[Concentration of light hydrocarbons in exhaled air depending on the risk factors of metabolic disorder].

In this study we investigated the effect of risk factors of metabolic syndrome on the content of light hydrocarbons (C2-C3) in exhaled air. We used a gas chromatograph with a short multi-channel column. As a result, sex differences in concentrations of light hydrocarbons presented in exhaled air were found. In addition, such factors as smoking and diabetes mellitus type 2 in relatives reflect on the exhaled C2-C3 compounds only in women. But the overweight correlates with the exhaled acetone (C3) only in men. Thus, the fact that the metabolic changes caused by the presence of risk factors of metabolic syndrome lead to changes in gas composition of exhaled air and can be registered and used for early diagnosis has been ascertained.
