- European researchers analyzed data to see if interruptions in sedentary activity could affect insulin resistance.
- The researchers included middle-aged participants from the Dutch Obesity Study Epidemiology and examined liver fat content and insulin resistance, along with timing of physical activity.
- The researchers found no link between sedentary activity cessation and reduced insulin resistance, but they suspected a possible link between exercise timing and insulin resistance. discovered.
- Morning exercise did not reduce insulin resistance, but researchers found that afternoon or evening exercise may be beneficial.

Because type 2 diabetes is expensive to treat, causes many health problems, and can even be fatal, researchers are interested in learning about different ways to improve insulin resistance.
Exercise is an important aspect of health. Previous studies have shown that it can improve insulin resistance. In a new study published in Diabetes (Journal of the European Diabetes Society), researchers found a relationship between exercise timing and insulin resistance.
The beta cells of the pancreas produce insulin, a hormone produced by the body that is involved in regulating blood sugar levels.
Some medical conditions, such as type 1 and type 2 diabetes, can affect your body’s ability to make and respond well to insulin.
Type 1 diabetes occurs when a person’s body produces little or no insulin. Doctors usually diagnose this form of diabetes early in life and there is no cure.
People who develop insulin resistance may be diagnosed with type 2 diabetes.
This form of diabetes is more common in middle-aged and older people. type 2 diabetes too
Unlike type 1 diabetes, people with type 2 diabetes may go into remission with lifestyle changes, including sometimes significant weight loss.
The researchers looked at data from the Dutch Obesity Cohort Study, which collected data from 6,671 people aged 45 to 65 between 2008 and 2012.
Data collected included BMI, fasting and postprandial blood glucose and insulin samples, and MRI scans of potential imaging studies. Additionally, 955 participants wore activity monitors during his four days.
From the group wearing activity monitors, the researchers narrowed the participant pool to 775 participants, with an average age of 56 years. The group composition was 42% male and 58% female, with a mean BMI of 26.2.
By examining data from activity monitors, researchers divided the duration of the day into three segments. 6pm to 12am (evening). They excluded the hours from 12:00 am to 6:00 am.
Every six hours, researchers looked at different levels of activity recorded by heart rate monitors.
After analyzing the data collected, the researchers found no association between cessation of sedentary activity and reduced insulin resistance. We found an association between insulin resistance and the time period during which participants engaged in moderate-to-vigorous physical activity.
They found no difference in MVPA and decreased insulin resistance in the morning portion of the data.
The researchers also looked at liver fat captured on MRI scans and noted that the number of breaks in sitting time had no effect on liver fat content.
“Further research is needed to assess whether the timing of physical activity is indeed important in the development of type 2 diabetes,” the authors wrote.
Dr. Michael SagnerPresident of the European Society for Preventive Medicine, medical news today About the survey results.
“It is certainly timely to investigate the chronobiological effects of exercise,” said Dr. Sagner. “Exercise timing is a relatively unexplored area in human research, and more research is needed.”
A weakness of the study, Dr. Sagner noted, was the limited time frame of four days in which participants were monitored, stating that “when certain types of activity were performed at certain times of the day, Whether it provides more health benefits,” he said, adding that more research is needed.
“The current research does not change current recommendations. Physical activity is essential for good health and disease prevention and should be incorporated into your weekly routine, regardless of timing throughout the day.”

Dr. Ishita Patel, board-certified endocrinologist at Texas Diabetes and Endocrinology, also said: MNT About research. Dr. Patel also thought that the timing of exercise to lower insulin resistance also needed more research.
“The study data analyzed were short-term, four days,” noted Dr. Patel. “It would be interesting to assess liver fat and insulin resistance over time. [its] Relevance to populations of interest, such as prediabetes and diabetics. “
As Dr. Sagner also mentioned, Dr. Patel thought the important thing about exercise was not to focus on timing, but to make it part of your routine.
“Most people are very busy and it’s hard to find time to exercise regularly. Much like we advise dieting, add the added challenge of finding the ‘perfect time’ to exercise.” More than that, I feel we need to encourage consistency with exercise.
