Abstract
The article shows studies conducted to study physiological and biochemical blood parameters after normobaric hypoxic training in combination with protein nutrition. The studies were conducted on 45 white male Sprague Dawley rats weighing 250-280 g. Hypoxic training in combination with protein nutrition led to an increase in red blood cells, hemoglobin, oxygen capacity of the blood, and a decrease in hematocrit. There was also an increase in plasma volume, lymph flow and urine output, while heart weight values remained within the normal range. Indicators of biochemical homeostasis of plasma and lymph do not go beyond the reference values, which indicate the normal maintenance of protein and mineral metabolism and the absence of pathological processes in the body. Studies have shown that the combination of normobaric hypoxic training at an altitude of 2800-3000 m above sea level with protein nutrition in animals improved the physiological state of the body, which will allow timely adjustment of nutrition to optimize the training process.
