Middle-aged men who maintain their muscle mass may lower their risk of heart disease as they get older, a new study suggests.
Beginning in the mid-30s, muscle begins to decline by about 3% each decade. Previous studies found that muscle mass is associated with heart attack/stroke risk, but those studies focused on people with heart disease.
In this new study, the researchers wanted to examine if muscle mass in middle age might be associated with long-term heart health in people without heart disease.
The study included more than 1,000 men and women, aged 45 and older, who were followed for 10 years. During that time, 272 participants developed heart disease, including stroke and minor stroke.
