Bewegungsmangel im Kindesalter führt zu erheblichen Herzschäden und erhöht das Risiko für Herzinfarkt und Schlaganfall. Leichte körperliche Aktivität ist das einzige wirksame Gegenmittel gegen Bewegungsmangel und es ist ziemlich einfach, drei bis vier Stunden am Tag anzusammeln

Increased sedentary time from childhood causes and worsens excessive heart enlargement, but light physical activity could reduce the risk of premature heart damage.

The new study from the University of Exeter was conducted in collaboration with the University of Bristol and the University of Eastern Finland, and the results were published in the European Journal of Preventive Cardiology.

In total, 1,682 children from the University of Bristol’s Children of the 90s cohort were followed up from age 11 to 24 years old. At baseline, they spent an average of six hours per day in sedentary activities, which increased to nine hours per day by young adulthood. This significant increase in sedentary time contributed 40 percent to the total increase in heart mass from ages 17 to 24 years. The results were similar in children and adolescents with either normal weight or overweight and obesity. Likewise, in children with either normal blood pressure or high blood pressure, sedentariness increased heart mass.
