American scientists found out that about a year of workouts helps to preserve or even improve the elasticity of the heart muscle in people with early signs of heart failure. This is reported in the article published in the Circulation Journal.
researchers focused on a state known as heart failure with a stored emission fraction, which is about three million people in the United States. It is almost incurable and characterized by increased rigidity of the heart muscle and high pressure inside the heart during exercise. As a result, it causes fatigue, excess fluid in lungs and legs and shortness of breath.
Previous studies call long exercise as a method that helps to significantly improve the elasticity of the heart in young people, but not affecting the hardness of the heart in people’s 65 years and older. In the new work, 31 people took part, who had some thickening of the heart muscle and an increase in blood biomarkers associated with heart failure, although they did not have such symptoms like shortness of breath.
eleven subjects included in the control group, a program of yoga and strength training was scheduled three times a week. The rest was appointed individually selected exercise mode: walking, cycling or swimming. In the future, participants began to perform intensive aerobic interval training at least 30 minutes at least twice a week, plus two or three exercises of the average intensity and one or two power workouts per week.
In a year in people who performed intensive exercise, physiologically and statistically significant improvement of heart rigidity and cardiorespiratory training were noted. However, so far, scientists cannot determine exactly whether they will develop heart failure or not, for which longer research is needed.
Earlier, the international team of scientists found out that long-term accommodation in areas even with low pollution of the atmosphere leads to an increased risk of stroke and ischemic heart disease.
