Gentle yoga may help people with type 2 diabetes to take off some weight because of their glycemic control, a small study suggests.
The survey of 123 adults middle-aged and older found that those who have added yoga to the treatment of diabetes standards throw a handful of books about three months. Meanwhile, their average blood sugar has remained stable - in contrast to the non-practicing yoga "control" group, whose blood sugar has increased.
The results reported in the journal Diabetes Care, do not suggest that yoga is meant to replace other forms of exercise for people with type 2 diabetes - a disease often associated with obesity.
To really lose weight and control blood sugar, the more vigorous exercise might work better, according Shreelaxmi V. Hegde Institute of Medical Sciences and Research Center Srinivas in Mangalore, India.
Of the 60 study participants who took yoga classes several times a week, the average BMI - fell from 25.9 to 25.4 - a measure of weight relative to height. A BMI between 25 and 30 considered obese.
"In our study of the effects of yoga on body mass index (BMI) and the control of blood glucose has been marginal," said Hedge, principal investigator of the work, told Reuters Health via email.
"But", he added: "It should be noted that yoga to control blood sugar levels that otherwise would be increased in the control group."
In addition, the study found signs of so-called oxidative stress decreased yoga group.
Oxidative stress refers to a situation where the levels of reactive oxygen species or "free radicals" - harmful by-products of energy in cells - grow beyond your body's ability to neutralize them. The long-term oxidative stress is thought to contribute to a host of chronic diseases.
In this study, the researchers measured blood levels of the participants Hegde of certain chemicals that reflect oxidative stress. They found that, on average, levels in the yoga group of chemicals fell 20 percent.
The significance of this is clear. Hegde said that if such a reduction of oxidative stress was sustained over time, can reduce the risk of diabetes complications, including heart and kidney disease, nerve damage and damage to blood vessels in your eyes.
In addition, long-term studies are needed to see if this is the case, the researchers said.
According to Hegde, yoga can reduce oxidative stress, because it stimulates the parasympathetic nervous system - the nervous system which in the end against the brake pedal is the sympathetic nervous system.
There are warnings. Yoga used in this study was a mild form, Hegde said, and some parts of practice have been adapted for people with additional health problems, poses some have been prevented in people with heart disease, for example.
In the real world, yoga classes vary greatly. Some people have a strong work-out, with complex cases that would not be appropriate for elderly people with chronic diseases.
Seniors with diabetes may find yoga classes designed especially for the elderly and those with chronic diseases. In the United States, local hospitals and community centers increasingly offer such classes.
