Краткий осмотр (реферат): | The article discusses the effect of inhalation of highly concentrated oxygen on the state of the cardiorespiratory reserve during steady-state exercise. Results. During the entire observation period, there was a lower perceived exertion at 8 minutes of observation, as well as a decrease in recovery time after inhalation of highly concentrated oxygen (p <0.05). While analyzing the heart rate before and after inhalation of highly concentrated oxygen, the increase in heart rate at 2, 6, 8 minutes of physical activity was less than similar indicators before oxygen inhalation (p <0.05). After inhalation of highly concentrated oxygen, a lower level of pressure in the cardiorespiratory system was observed - due to a decrease in RER by 2, 4, 6, 10, 12, and 15 minutes (p <0.05) with the same initial value during warm-up. A lower heart rate was observed during warm-up, as well as at 2, 8 and 15 minutes of observation after inhalation of highly concentrated oxygen (p<0.05). Significant shortening of the recovery time was set (p<0.05). The absolute oxygen pressure increased at all stages of observation by 20-50% - at the 2nd, 4th, 8th, 10th, 12th, 14th minutes of physical exertion and during the restitution period (p <0, 05). Physical efficiency, with the use of inhalations of highly concentrated oxygen, increased in 2.3 times. The percentage of increase in double product (DP) was 25.5% (p <0.05). Accordingly, the chronotropic reserve index increased by 14.3% and the inotropic reserve index by 16.2%. |
