Strength training burns fat around the heart

Strength training (with resistance) burns fat that is stored around the heart and is linked to cardiovascular disease, according to a new Danish study published in JAMA Cardiology.

Strength training (with resistance) burns fat that is stored around the heart and is associated with cardiovascular disease, according to a new Danish study published in JAMA Cardiology.

Researchers at Copenhagen University Hospital found a decrease in a certain type of pericardial fat (pericardial adipose tissue) in strength training patients. Aerobic endurance exercise as well as resistance exercise contributed to the reduction of another type of heart fatty tissue (epicardial).

“As is known from other studies, resistance training is a stronger stimulus to increase muscle mass and basal metabolic rate than endurance training. And so we assume that participants in resistance training burn more calories during the day - as well as in inactive periods - compared to those who train endurance,”said lead author Dr. Regitse Hojgaard Christensen.

The experiment, which lasted 12 weeks, involved 50 obese adult volunteers who were sedentary, but at the time did not have heart disease, diabetes or atrial fibrillation. They were randomly assigned to three physical activity groups:

high-intensity endurance training - 3 times a week for 45 minutes,

  • weight training - 3 times a week for 45 minutes,
  • no change in activity level (control group).

Each participant underwent an MRI of the heart at the start and end of the study.

Compared to controls, endurance training was found to reduce epicardial adipose tissue mass by 32%, and strength training by 24%. However, resistance training alone affected pericardial adipose tissue, reducing its amount by 31%.

“The resistance training in this study was designed as a 45-minute interval, medium weight, repetitive, time-controlled workout. Participants performed three to five sets of 10 exercises, and the sessions were supervised. We did not combine endurance training and strength training, although it would be interesting to identify their potential additive effects,”said Christensen.

Chadi Alraeis, head of the Department of Interventional Cardiology at the Cardiology Hospital at Detroit Medical Center, said the study is interesting precisely because it looks at the specific link between exercise and pericardial fat.

“Along with the time you spend on the treadmill, you can add a little dumbbell work or lunges, squats or push-ups. It may even be enough to bring some weights to the office so that you can use them there,”he said.
