Type 2 Diabetes: High-intensity exercise can restore heart function


Type 2 diabetes can sometimes cause loss of heart function. However, the results of new studies show that this function can be restored through intensive training.

About 90-95% of the 30 million people in the United States suffer from type 2 diabetes type 2 diabetes, the body’s cells are resistant to the action of insulin, the hormone that converts blood sugar into energy. help.

Insulin, which cannot activate energy conversion into cells, causes an increase in blood sugar levels in the body and creates conditions for pre-diabetes and type 2 diabetes.

Increased blood sugar levels can be very dangerous, which can cause loss of vision and serious health problems in various organs, including the heart and kidneys.

Researchers are behind new studies from the University of Otago in Dunedin, New Zealand, and they have published their work at the American College of Sports Medicine, Medicine and Science in Sports and Exercise.

They say exercise is probably the best way to prevent heart disease in people with type 2 diabetes. However, they realize that one problem might be that many people with this condition have heart failure and therefore cannot exercise enough. can benefit from this exercise.

The Otago team has shown this in its study, which focuses on the benefits of HIIT. HIIT includes short sprints or stapes attacks with fairly intense exercises such as jogging or walking fast.

HIIT for 3 months improves heart function

In the study, 11 middle-aged adults with type 2 diabetes participated for 3 months in a 25-minute exercise that included 10 minutes of very active activity.

The team measured heart function at the start of the study and at the end of the three-month study period. They then compared these steps with the control group consisting of five participants who had not completed the training.

The study found that subjects who underwent HIIT had improved heart function after 3 months and that these results did not change their medication or diet.
Exercise mode for middle-aged adults with type 2 diabetes, with an impressive level of adherence of 80% while research is more important, research shows that high-intensity programs are safe and profitable.

Scientists need to reproduce results in larger studies to determine the benefits of HIIT in people with type 2 diabetes.

Lead author Genevieve Wilson, who has studies as part of her doctoral thesis, said the team’s results showed that exercise can provide high intensity, practical ways to reverse loss of heart function caused or reduce type 2 diabetes. “

Wilson added that this is important because the most common cause of death in people with type 2 diabetes is heart disease.

Senior Fellow of Danidinskoto School of Medicine Chris Baldi will manage the work of consultant cardiologist Wilson and professor in the Department of Medicine, Jerry Wilkins.

Together, the researchers found that this study showed that HIIT programs were safe for middle-aged adults with type 2 diabetes and that participants were able to survive most of the time.

“This work has two important clinical consequences,” Dr. Bald. The first is that adults with type 2 diabetes undergo high intensity interval training and are able to compare aerobic capacity and left ventricular frequency response as in non-diabetic adults.

“Second, high-intensity exercise can reverse some changes in heart function that seem to overtake diabetes heart disease,” he continued.
Reducing the risk of heart complications
For people with type 2 diabetes, the National Institute for Diabetes and Digestion and Kidney Disease recommends several steps that are useful for reducing the risk of heart disease.

This is ABC Diabetes Management:

  • A stands for A1C test, which shows the average blood sugar level in the last 3 months. For most people, ideal A1C is less than 7%, but the health team can help determine the right goals.
  • B stands for blood pressure. High blood pressure can cause a heart attack. The target of blood pressure for most diabetics is below 140/90 mm Hg.
  • C for cholesterol. Too much “bad” cholesterol (LDL cholesterol) in the body can clog arteries and increase the risk of heart attack or stroke. Statins can help reduce this cholesterol.
  • S is quitting smoking. Diabetes and smoking from two narrow blood vessels force the heart to work harder. Smoke withdrawal reduces the risk of heart attack and other diseases.
