Strength training may cut diabetes risk in obese people

Press Trust of India  |  Washington 

Strength training over a short time period may be a fast and effective strategy for reducing the risk of and in obese people, a study has found.

Researchers from in Brazil investigated the effects of strength-based exercise on liver accumulation, blood glucose regulation and markers of in obese mice.

According to a study published in the Journal of Endocrinology, strength training can reduce stores in the liver and improve blood glucose control in obese mice.

The study reports that strength training over a short time-period, less than would be enough to change body composition in humans, was sufficient to reduce the accumulation of liver fat and improve regulation of blood glucose in obese mice, even without overall loss of body weight.

is a growing, global epidemic that needs more effective intervention strategies to avoid debilitating complications including and

Approximately 94 per cent of obese people are diagnosed with non-alcoholic fatty liver disease, which leads to in this vital organ and impairs its ability to regulate blood glucose.

This increases the risk of type 2 and its associated serious complications, including nerve and kidney damage.

Although increased physical activity is a widely accepted method of improving and aiding weight loss, the relative benefits of different types, durations and intensities of physical activities are still under much debate.

A wealth of research has focussed on the benefits of energy-burning aerobic exercise, with the potential benefits of muscle-building strength and resistance training often neglected.

For the study, obese mice were made to perform strength training over a short time-period, the equivalent of which in humans would not be enough to change their body fat composition.

After this short-term training the mice had less fatty livers, reduced levels of and their blood glucose regulation was improved, despite no change in their overall body weight.

"The fact that these improvements in metabolism occurred over a short time, even though the overall amount of body fat was unchanged, suggest that strength training can have positive effects on and directly affect liver function and metabolism," said from

However, mimicking strength training in animals is difficult and more investigation is required to really understand how liver metabolism is affected by it, Pereira de Moura said.
