Study says exercise lowers risk of heart disease

Exercise may reduce the amount of fatty tissues around the heart that have been associated with an increased risk of heart disease.

That's the finding of a study conducted by researchers at the Centre for Physical Activity Research in Copenhagen.

Fifty inactive adults with abdominal obesity were randomly placed in study groups separated by no exercise with placebo, no exercise with medication, endurance exercise with placebo, endurance exercise with medication, or  resistance training with placebo.

The study, published in JAMA Cardiology, took place over 12 weeks and MRI was used to measure two types of fatty tissue -- epicardial tissue (fat lying closer to the heart) and pericardial tissue (fat lying further outside the heart).

Both the endurance and resistance training were associated with significant reductions in epicardial tissue, while only resistance training was associated with reductions in pericardial tissue.

There were no differences identified in other metabolic factors that were measured, such as blood pressure or heart rate.
