The untrained animals with mild cognitive impairments, meanwhile, continued to lag far behind the others in their ability to find and recall the chamber. With a little practice, though, the weight-trained animals, despite their induced cognitive impairments, caught up to and in some cases surpassed the speed and accuracy of the controls. Far less has been studied about resistance training and its effects on the brain. Finally, to better understand how ladder climbing might have changed the rats’ brains and minds, scientists examined brain tissue from each of the groups. Mr. Kelty’s solution, a modification of methods used in some earlier studies, involved a 100-centimeter-long ladder (a little over three feet) and bags of weighted pellets gently taped to the rats’ rear ends.

He and his collaborators knew that to closely study brain changes related to resistance training, they would need to induce animals to lift weights. But in time, the weight-trained animals, despite their induced cognitive impairments, caught up to and in some cases surpassed the speed and accuracy of the controls. The finding may have important brain-health implications for those of us who are not literal gym rats. No Comments *Adapted from the New York Times article by Gretchen Reynolds . But a wealth of helpful past research indicates that regular aerobic exercise, such as walking or jogging, can prop up memory and cognition. We appreciate you sharing you feedback on what you enjoy and what you feel needs work. Many people find that as they approach middle age, things that were easy to remember suddenly begin to elude them; like people’s names or where they left their car keys. Choose areas of interest Weight training may have benefits for brain health, at least in rats. In this new study, they used rats and ladders to examine it more closely.

After several weeks, the climbers showed increased muscle mass, indicating that the activity was effective weight training.

In these studies, which have involved people and animals, aerobic exercise generally increases the number of new neurons created in the brain’s memory center and also reduces inflammation. But the study certainly does suggest that resistance training can help.

But their success differed. As the climbing became easier, the mass of the pellets in their bags was increased, just as people progressively add to the weight they lift at gyms. The study also cannot tell us whether aerobic exercise leads to similar, differing or complementary molecular changes in our brains, or if healthy people gain the same benefits as those with impairments. 310-582-8212, Categories: Featured Articles, SPORTS TRAINING, STRENGTH, STRETCHING AND FLEXIBILITY. The team recruited 68 women and 32 men ages 55 through 86, all of whom had mild cognitive impairment, and randomly assigned them to two groups. Familiar names, words and the current location of our house keys begin to elude us. The weight training had “effectively restored” their ability to think, Mr. Kelty says. In animals, weight training appeared to promote the creation of new neurons in the memory centers of the brain. A recent study published in the Journal of Applied Physiology shows that weight training may not just benefit our bodies, it may also have brain health benefits. Weight training may have benefits for brain health, at least in rats. Half of these rats then began a weekly program of weight training. “I think it’s safe to say that people should look into doing some resistance training,” he says. When rats lift weights, they gain strength and also change the cellular environment inside their brains, improving their ability to think, according to a notable new study of resistance training, rodents and the workings of their minds.
