Exercise in the morning does not seem to have any benefit for reducing insulin resistance, however, exercise in the afternoon or evening lowers the risk of diabetes by regulating blood sugar.
This was discovered in a significant study.
It has long been maintained that maintaining a daily programme of physical activity promotes metabolic health.
However, the biological mechanisms underpinning the possible advantages of scheduling physical activity are yet unknown, and this is because this area of human biology is still largely unexplored.
According to a recent study that was just published in Diabetologia, physical activity in the afternoon or evening is linked to better blood sugar regulation.
Reducing Insulin resistance
The timing of physical activity throughout the day may be crucial to the positive benefits of physical activity on insulin sensitivity, they stated in the research. Additional research is required to determine whether the timing of physical activity affects the development of type 2 diabetes.
Researchers used information from the Netherlands Epidemiology of Obesity (NEO) study for their investigation.
In addition to a physical examination where blood was drawn to evaluate blood sugar and insulin levels before and after meals, participants also completed questionnaires to provide information on their demographics, lifestyle, and clinical conditions.
Additionally, they underwent MRI screenings to determine if they were a good candidate for the surgery, and of those who could, around 35% were chosen to have their body fat levels measured. liver by use of this method.
The findings revealed no discernible distinction in insulin resistance between morning and daytime activities.
It was discovered that neither the duration of sedentary behaviour nor the number of breaks from it was positively associated with the quantity of hepatic fat or insulin resistance.

What does the Latest Study say?
A significant study shows that afternoon or evening exercise is now related to better blood sugar control to reduce the risk of diabetes in adults while morning exercise has no benefits in reducing insulin resistance.
The timing of physical exercise throughout the day may affect metabolic health, it has long been believed.
However, the timing of physical activity is a relatively uncharted area in human biology, and it is still unknown what physiological processes might underlie any potential advantages.
Now, a new study found that afternoon or evening physical activity is linked to better blood sugar control. This study was published in Diabetologia.
Dr Jeroen van der Velde and his associates at the Department of Clinical Epidemiology led the investigation. The Netherlands' Leiden University Medical Center.
The Netherlands Epidemiology of Obesity (NEO) study data were used in the study.
It's possible that the level of activity during the study's breaks was too low to trigger metabolic reactions, according to the researchers.
The majority of daily activities are of a low to moderate intensity, so it makes sense that there is no correlation between insulin resistance and breaks as we have not seen one between LPA and LPA.
Nevertheless, more research is needed to determine whether the timing of physical activity affects type 2 diabetes.
- Physical activity research
Data from 6,671 people between the ages of 45 and 65 who participated in the Netherlands Epidemiology of Obesity Cohort Study were obtained between 2008 and 2012.
BMI, fasting and post-meal blood glucose and insulin samples, as well as MRI scans of those who were eligible for imaging, were some of the data gathered. 955 participants additionally wore activity trackers for 4 days.
The researchers narrowed the pool of participants from the activity monitor group to 775 individuals with an average age of 56. There were 42% men and 58% women in the cohort, and their average BMI was 26.2.
The researchers divided the daily periods into three segments using data from the activity monitors: 6:00 a.m. to 12:00 p.m. (morning), 12:00
12 a.m. to 6 p.m. in the evening and from 6 p.m. to the afternoon (evening). They did not include midnight to six in the morning.
The scientists examined the various levels of activity shown by the heart rate monitors for each of the six-hour periods.

Breaks from the sedentary activity and decreased insulin resistance were not associated, according to the analysis of the data. However, they did discover a link between insulin resistance and the time of day the subjects engaged in moderate-to-vigorous exercise, as shown by the activity monitors.
The results indicate that moderate-to-vigorous physical activity in the afternoon reduced insulin resistance by 18% and that the same forms of activity in the evening were related to a reduction in insulin resistance by 24%.compared to physical exercise spread out throughout the day, inked to a 25% reduction.
In the morning section of the data, they discovered no differences in MVPA and decreased insulin resistance.
The number of breaks in sedentary time had no effect on the liver fat content, the researchers found when they looked at the liver fat images from the MRI scans.
- The authors stated that additional research is necessary to determine whether the timing of physical exercise is actually crucial for the development of type 2 diabetes.
- Type 2 diabetes and insulin resistance
Insulin is a hormone the body produces that controls blood sugar levels, and it is produced by beta cells in the pancreas.
Type 1 diabetes and type 2 diabetes are two medical diseases that can affect how well the body produces or uses insulin.
When a person has type 1 diabetes, their body either produces very little or no insulin. This kind of diabetes is typically diagnosed early in life, and there is no known treatment.
Those who experience insulin resistance may be identified as having type 2 diabetes. Those who are middle-aged and older are more likely to have this type of diabetes. Additionally, type 2 diabetes is more common. People who are obese or overweight can manage their condition with medicine, a healthy diet, and exercise.
Contrary to type 1 diabetes, type 2 diabetes can occasionally be controlled with lifestyle modifications, including significant weight loss.
The researchers discovered that exercising in the afternoon was associated with an 18% reduction in insulin resistance and exercising in the evening with a 25% reduction when compared to distributing activity throughout the day.
Additionally, they discovered that time spent engaging in vigorous to moderate physical activity decreased insulin resistance and hepatic fat levels.
Van der Velde and colleagues did not discover any appreciable differences in insulin resistance between morning exercise versus exercise distributed throughout the day.
- Any time is a good time to exercise.
Exercise is useful at any time of day, so it's "a little bit problematic," in Correa's opinion, to argue that one time is preferable to another.
He emphasized the study's use of a relatively small sample size to arrive at its conclusions.
He advised caution, saying, " I think we have to look at it with a grain of salt," he said, urging caution. "Because if we provide an exercise programme to a patient, it will depend on their rely on their availability at the time". We shouldn't advise patients to exercise exclusively in the afternoon because some of them are available in the morning.
What is Insulin resistance?
Insulin resistance happens when cells stop responding to insulin, according to Dr Ricardo Correa, director of the endocrinology, diabetes, and metabolism fellowship programme at the University of Arizona College of Medicine.
So when insulin is present, the insulin receptor "activates a cascade so glucose may enter the cell," he explained.
He explained, "What happens is that when that receptor is broken, it can't initiate the cascade so glucose can't come in. "All the glucose will remain outside the cell," as a result.
If glucose cannot enter the cells, blood sugar levels stay high and type 2 diabetes develops.
The risk of developing insulin resistance is highest in those who are overweight or obese, according to Correa. Insulin according to him, the first stage of developing type 2 diabetes is resistance.
How exercise reduces insulin resistance
Physical activity offers a different approach that does not involve insulin signalling, according to Correa. Therefore, he explained, "the two ways that glucose can enter the cell are through the insulin receptor or through exercise." As a result, exercise can aid in blood sugar management, which in turn can help to enhance insulin sensitivity by reducing insulin resistance.
Thus, he continued, "Whenever we exercise, we permit passage of glucose into the cells because glucose offers energy in exercise this is a way the body must obtain energy.
The conclusion
According to recent studies, exercising later in the day can help obese or overweight patients with their insulin resistance. That's why we have discussed here reducing insulin resistance.
Since exercise is helpful at any time, experts believe this doesn't mean we should just exercise in the afternoon.
They add that more research is required to determine whether evening exercise will have the same positive effects on every
FAQ
Q.1. Does physical activity reduce control of blood sugar?
Ans: Yes, physical activity can lower your blood sugar up to 24 hours or more. After your workout, it makes your body more sensitive to insulin.
