Now diabetes is one of the major problems for worldwide people which are increasing like epidemically. Diabetes is a life-long disorder that affects the way your body handles glucose, a kind of sugar, in your blood. Diabetes in the United States is reaching epidemic proportions. About 1 in 10 Americans are estimated to have diabetes which means that more than 29 million people are facing these disorders.


Further,an additional 86 million are thought to have prediabetes; this describes a state where an individual's blood sugar level is higher than it should be, but not high enough to trigger a diabetes diagnosis. It is considered an early warning signal.


As the date showing the global number of type 2 diabetes cases , it expected to hit 592 million by 2035, all knowledge of how this disease might be managed is vital.


Normally hyperglycaemia or raised blood sugar is a common effect of uncontrolled diabetes and over time leads to serious damage to many of the body's systems, especially the nerves and blood vessels.

There are two main types of diabetes:


Type 1 diabetes– where the body's immune system attacks and destroys the cells that produce insulin


Type 2 diabetes – where the body doesn't produce enough insulin, or the body's cells don't react to insulin 


The risk factors for type 2 diabetes (the most common version of diabetes) are well known.


Being overweight or obese, high blood pressure, abnormal cholesterol and triglyceride levels, and inactivity are all known to play a substantial role. All of the above can be managed, at least in part, by exercise.

The role of exercise on diabetes – A new look

The latest research, published this week in the journal ‘Diabetologia’, takes a deeper look at the role of exercise in the development of type 2 diabetes. It is the most in-depth study to examine exercise independent from other influential factors, such as diet. The conclusions from the report are clear:

           

Physical activity guidelines in the U.S. and the United Kingdom recommend 150minutes of moderate activity or 75 minutes of vigorous activity per week

           

"This research revealed that some physical activity is good, but more is better," said Dr Soren Brage, from the Medical Research Council Epidemiology Unit at Cambridge University and co-author of the research.


Presently, physical activity guidelines in the U.S. and the United Kingdom recommend 150minutes of moderate activity or 75 minutes of vigorous activity per week; this could include cycling, walking, or sports. However, according to the Centers for Disease Control and Prevention (CDC), fewer than 50 percent of American adults meet these recommendations.


The latest research was a result of collaborative work between two institutions -University College London and the University of Cambridge, both of which are based in the U.K. Data from more than 1 million people was collated. In all,the team analyzed 23 studies from the U.S., Asia, Australia, and Europe.

Credits to the vast amount of data and information available to them, the investigators were able to strip out the effects of exercise and examine them independently of other behavioral factors, such as diet and smoking. This is in contrast to earlier work that has not been able to isolate the impact of physical activity alone.

           

More exercise is better for reducing the risk of diabetes

           

The researchers found that any exercise is beneficial in staving off diabetes, but individuals who exceeded the 150 minute recommendation saw the greatest benefits.

More exercise is better for reducing the risk of diabetes

As stated by the analysis, cycling or walking briskly for 150 minutes each week cuts the risk of developing type-2 diabetes by up to 26 percent.


The people who exercise moderately or vigorously for an hour each day reduced their risk by 40 percent. At the other end of the scale, for those who did not manage to reach the 150 minute target, any amount of physical activity they carried out still reduced the risk of type 2 diabetes, but to a lesser extent.


"Our results suggest a major potential for physical activity to slow down or reverse the global increase in type 2 diabetes and should prove useful for health impact modeling, which frequently forms part of the evidence base for policy decisions.,"says the main scientist Andrea Smith.


As mentioned, exercise has long been known to reduce the risk of developing type 2diabetes; however, now we have a clearer picture of the exact figures behind this effect. As Dr. Brage says:


"These new results add more detail to our understanding of how changes in the levels of physical activity across populations could impact the incidence of disease. They also lend support to policies to increase physical activity at all levels. This means building environments that make physical activity part of everyday life."
