A little exercise to get back in shape after a heart attack, it’s good. Too much is dangerous! This is what researchers at the hospital of Hartford, in the United States, in the specialized journal Mayo Clinic Proceedings. Indeed, according to their research, running more than 48 km or walking more than 74 km per week increases the risk of cardiovascular mortality in heart attack survivors.
These results cannot be applied to the general population, remind the study authors, because regular physical activity reduces the risk of death in people with cardiovascular disease, hypertension, type 2 diabetes or in victims of a stroke.
Do not exceed the limits
By the way, the official medical guide in the United States recommends about 150 minutes of moderate exercise per week or 75 minutes of vigorous exercise. After analyzing the activity of 2,400 heart attack survivors, the researchers say that exceeding the recommended limits only increases the risks mortality.
“These results suggest that the benefits of running or walking do not increase indefinitely and that beyond a certain level, perhaps 48 kilometers per week, there is a significant increase in risk.” , they conclude.
