Body Fat and Heart Disease

Strength Training Reduces Heart Fat

By Shirley Archer, JD, MA | May 1, 2020 |

Location matters with body fat. The accumulation of excess fat around the heart can increase the risk of cardiovascular disease. A new study by researchers at the University of Copenhagen in Denmark assigned participants to resistance training, high-intensity interval endurance training (HIIT) or no exercise. Results showed that only people who lifted weights decreased the fat lying closest to the heart—specifically, inside the sac that encases the heart (the pericardium).

A Strong Diaphragm for a Strong Core

By IDEA Editorial Staff | January 28, 2020 |

When you think about exercising core muscles, do you remember your diaphragm? Its two main functions involve breathing and biomechanics, and it’s one of the most important muscles for maintaining intra-abdominal pressure (Nelson 2012). Intra-abdominal pressure is like a weight belt applied from the inside. If your body can’t regulate this pressure, you may experience poor motor control and lack of spinal stability. Plus, when the diaphragm is not properly engaged, other muscles must compensate, increasing your risk of injury.

Midlife Gait Speed Linked With Lifelong Aging

The Mighty Mitochondria

By Sarah Kolvas | December 19, 2019 |

It’s time to revisit one of the basics of biology: mitochondria. These organelles, which occur in almost all types of human cells, generate adenosine triphosphate (ATP), the energy that cells use (New­man 2017; Newman 2018). They are critical for powering metabolic processes, making them a building block of physical health and fitness.
