Objective of the study: To evaluate the impact of interval hypoxic-hyperoxic training on the biochemical and hematological profile of an athlete.

Methods and structure of the study: The scientific experiment involved 10 male athletes, aged 16-17, sport type -- swimming, qualification 1 sports category and candidates for master of sports, in the preparatory period. All athletes underwent the procedure of interval normobaric hypoxic-hyperoxic training (IHHT) according to the standard protocol: 5 cycles, including 5 minutes of hypoxia (oxygen concentration 13%) and 3 minutes of hyperoxia (oxygen concentration 32%). The device «OXYTERRA», Russia, was used.

Results and conclusions: It has been established that IHHT leads to an increase in the hemoglobin level after a course of procedures in swimmers. Statistically significant differences in the activity of lactate dehydrogenase before and after the cycle of procedures have been obtained, which shows an improvement in the processes of oxygen delivery to tissues, as well as the activation of recovery processes in athletes.

Keywords: Interval hypoxic-hyperoxic training, athletes, hemoglobin, creatine kinase, lactate dehydrogenase.
