US researchers have found that the "healthy" ingredient in red wine, resveratrol, may prevent the negative effects that spaceflight and sedentary lifestyles have on people. Scientists studied rats that underwent simulated weightlessness by hindlimb tail suspension and were given a daily oral load of resveratrol.
The control group showed a decrease in soleus muscle mass and strength, the development of insulin resistance, and a loss of bone mineral density and resistance to breakage.
AdvertisementThe group receiving resveratrol showed none of these complications.
The study results further demonstrated some of the underlying mechanisms by which resveratrol acts to prevent the wasting adaptations to disuse-induced mechanical unloading.
It also suggested that the compound might be able to prevent the deleterious consequences of sedentary behaviors in humans.
The study was published in the FASEB Journal.
