[Efficiency of an arbitrary respiratory rhythm reducing method in students of special medical physical educational groups].

Three-month decreased voluntary optimum respiration rate (DVORR) trainings during therapeutic exercises in students with various abnormalities caused increases in vital capacity and chest circumference amplitude. DVORR also affected cardiovascular performance. During exercises, heart rate decreased and pulse pressure increased, suggesting economized cardiac performance and better myocardial function. The use of this method in the students reduces morbidity, improves health, and increases physical fitness and progress in studies.
