Ever Heart Attack, Do not Overuse Sports



    People who have had a heart attack are advised to exercise regularly to improve heart health. However, a study revealed, there are certain limitations for them to obtain optimal results. 
"Exercising more does not mean better for them," said study researcher Paul Williams, researchers at Lawrence Berkeley National Laboratory, California, USA. 
Williams and his team analyzed approximately 2,400 people who have had heart attacks for which they do exercise patterns. Long-term studies that follow participants who exercise run and walk for about 10 years. Generally, an increase in the portion of exercise reduces risk of dying from heart disease by 65 percent. 
However, running more than 48.2 kilometers (km) or walking more than 74 miles per week, it will give the opposite effect. Researchers revealed that the portion of the sport can actually double the risk of heart attack. In this study period, 526 participants died, nearly three-quarters due to attack or heart disease. 
Because this study was limited to people who have experienced a heart attack, then Williams could not confirm these findings can be applied to all healthy adults, especially who like excessive exercise. 
Meanwhile, excessive exercise in people who have had heart attacks are rare. Of all study participants, only 6 percent reaching the threshold set researchers. In the majority of participants, increasing the portion within the limits of moderate exercise reduces the risk of death associated with heart disease. 
Carl Lavie, medical director of cardiac rehabilitation and prevention at the John Ochsner Heart and Vascular Institute, said the study showed that people do not need to do too much exercise for optimum benefit, particularly for improving heart health. 

Experts agree, recommendation of 150 minutes of moderate-intensity exercise and 75 minutes of heavy intensity exercise a week is enough for everyone in general.
