Heart failure occurs when the heart is not able to supply adequate quantity of blood to the rest of the body. It is characterized by shortness of breath and a reduced ability to exercise. The American Heart Association has revealed that higher level of physical activity lowers the risk of developing heart failure, rather than just following the US physical activity guidelines recommendation.
The researchers suggested that the current US physical activity guidelines recommend of a minimum of at least 150 minutes of moderate intensity physical activity a week. This was associated with only a modest reduction in heart failure risk. Whereas, increasing this routine to twice the minimum recommended dose helps to reduce the risk of heart failure.
Jarett D. Berry, senior author of the study, said, "Walking 30 minutes a day as recommended in the US physical activity guidelines, might not be enough for healthy heart, so one should do more physical activity to reduce the risk of heart failure. The decreasing heart problems with increasing physical activity was consistent across all age, sex, race, and geographic location based subgroups studied."
The research is published in Circulation.
