Burst Exercise in Newly Diagnosed Diabetes Patients Improves Cardiometabolic Status

HbA1c and lipids show improved with high-intensity physical activity.

There are many complications that are associated with type 2 diabetes, with heart disease being the major cause of death and illness in the people with type 2. However, an exercise intervention may improve cardiac function in patients with diabetes.

Researchers wanted to explore the effects of burst exercise in newly diagnosed patients with diabetes, since physical activity played an important part for patients to control their glycemic level. A study published in the Canadian Journal of Cardiology compared the impacts of high intensity burst and sustained exercises on several factors that related to heart disease, such as BMI, exercise adherence, cardiopulmonary fitness, blood sugar levels and lipid profiles.

Data was collected from a local diabetes rehabilitation center in Canada. 76 newly diagnosed patients were randomized into a control group and a intervention group. The control group was required to do 30 minutes of sustain physical activity at 60% age-predicted target heart rate, while the intervention group was required to a high-intensity burst exercise, which involved 3 periods of 10 minutes at 85% of target heart rate. The average age of patients was 65 years old with an average BMI of 31 kg/m2.

In the results, burst exercise patients showed greater improvement in HbA1c. Other than that, the intervention group also improved their lipid profiles, BMI and cardiopulmonary fitness.

This study provided health information for people who were just diagnosed with type 2 diabetes, and those patients may choose burst exercise instead of doing sustained exercise. However, the sample size of this study was relatively small, and the duration of intervention was only 3 months. In the future, more researches should involve larger and more diverse populations.

Practice Pearls:

  • A Canadian study of 76 patients with newly diagnosed type 2 diabetes accessed the impact of burst exercise in their cardiometabolic factors.
  • Burst exercise patients showed greater improvement in HbA1c, lipid profiles, BMI and cardiopulmonary fitness.
  • In future, more research should involve larger and more diverse populations to prove this clinical outcome.
