1. Researches conducted on an isolated heart demonstrate that hypercapnia increases the coronary blood flow, while hypocapnia decreases it.
2. The vast importance of the training is best shown on the example of collateral blood circulation. Regular trainings on “Samozdrav” produces additional branching of the vessels, which improve the nutrition and the blood supply of the heart.
3. Moderate hypercapnia induces the venous blood flow to the heart, increases the systolic volume as a result of the increase of the tonicity of the veins and the skeleton muscles, diffuses the blood flow.
