Introduction: Ability quick recovery is one of the decisive factors determining the achievement of high results in skiing. The aids and methods that increase adaptive capacity of an athlete are noteworthy. One such method may be use of hyperoxic mixtures (Han, Kim, Lim, & Kim, 2011). Methods: The purpose of the study is to determine the influence of hyperoxic gas mixture on urgent restoration processes. 35 skiers performed maximal treadmill test. During 20 minutes of recovery they were breathing hyperoxic gas mixture with an oxygen content of 93%. Indicators recorded: heart rate (beats / min) Polar SX800, blood pressure (mmHg) and also were assessed HRV and athletes respiratory systems indicators. Results: The 20 minutes hyperoxic inhalation after the maximum load contributes to the acceleration of the urgent restoration of the cardiovascular and respiratory systems skiers. VC athletes by recover normally was 4,94 ± 0,23 l, after hyperoxic breathing gas mixture was 5,39 ± 0,18 l (p <0,05). Skiers HR by 20 min recovery normally was 100 ± 4 beats / min, after hyperoxic breathing gas mixture - 2 ± 93 beats / min (p <0,05). Discussion: Under the conditions of hyperoxic inhalation functional state of the cardiovascular system skiers characterized by the lower heart rate (p <0,05), that indicating that reducing the energy needs of the heart. Breathing hyperoxic mixture leads to a faster recovery VC athletes. Probably hyperoxia leads to increased oxygen consumption and an increase in the coefficient of its use , which contributes to the rapid elimination of the oxygen debt . Inhalation of air breathing mixtures containing 93% oxygen for 20 minutes after the emergency rehabilitation of the maximum load leads to a decreasing of sympathetic influences on heart rate skiers and increasing activity of the parasympathetic division of the autonomic nervous system.
