Evaluation of some biochemical indicators of blood of high-qualified short-track sportsmen under the combined influence of specific physical load and low-intensive laser radiation

Monitoring of biochemical parameters of blood allows to determine the individual characteristics of athletes’ body and evaluate the effectiveness of building a training process. The increasing volume of physical activity during the preparatory period forces us to search for means of rapid increase in the functional level state and physiological reserves of an organism. In this regard, as one of the methods, the physiotherapeutic course effect of low-intensity laser radiation can be used. It was revealed that a specific physical load leads to a significant increase in lactate and total blood protein levels. So, in short-trackers in a state of relative physiological rest, the concentration of lactate was 2,77±0,24 mmol/l, which is much higher than the norm (the norm is 1,3±0,35 mmol/l). After the course of low-intensity laser radiation, the lactate level decreased insignificantly (2,52±0,19 mmol/l), but did not reach normal values. After the action on the body of a specific physical load, lactate concentration increased significantly, reaching a level equal to 9,24±0,43 mmol/l. The conducted course laser therapy allowed to reliably (р 0,05) lower its level to 6,25±0,32 mmol/l. In this case, urea and creatinine had only a tendency to increase. Thus, low-intensity laser radiation against the background of a specific physical load makes it possible to bring the investigated parameters close to the boundary of the physiological norm.
