Hour of exercise a day may cut heart risk in half

Thirty minutes to one hour of exercise a day may be enough to reduce a person’s risk of heart failure by nearly 50 percent, according to new research.

Scientists in Sweden conducted a long-term study between 1997 and 2010, which involved nearly 40,000 people between 20 and 90 years old. At the beginning of the study, the participants were asked to fill out a questionnaire about their medical history and lifestyle factors, including levels of physical activity. None of the participants had had heart failure.

The results revealed a direct relationship between activity levels and risk of heart failure. Specifically, the participants who had more than one hour of moderate exercise or 30 minute of vigorous exercise per day lowered their risk of heart failure by approximately 46 percent.

The findings, published in the journal Circulation: Heart Failure, are in line with the American Heart Association’s recommendation for 150 minutes of moderate intensity physical activity every week. Examples of moderate exercise include brisk walking, dancing and gardening.
