There is abundant evidence that aerobic activities are great for the brain of the elderly, but the benefits of lifting weights have been much less explored. We now know that older women who do this kind of training experience an improvement in cognitive functions. And this has been shown in females between 65 and 70 years who had not previously practiced. The work demonstrates just published in Archives of Internal Medicine.

The results are striking, since this is a clinical trial of 12 months duration, conducted in a controlled manner. Participants were divided into three groups. The first two made-legged endurance exercise once or twice a week. The third party executed only gym toning and balance. The researchers measured the cognitive abilities of all of them at baseline, after six months and one year.

The women who did weight training improved their mental prowess in two aspects: conflict resolution and selective attention (ability to answer the essential questions of a task or situation and ignore those that are irrelevant). On the physical level, we observed a positive effect on muscle function and speed during walking, which is closely associated with the risk of falls and disability. Moreover, studies show that being able to walk at a good rate is closely related to cognitive functions.

The charge of the work stress that no one can speak of a general improvement in mental skills, but a series of very specific advantages. In fact, tests showed no impact of strength training on memory.

Participants who performed the other training-toning and balance-not extracted any significant benefit from their efforts. “These findings have important clinical implications because cognitive impairment is a major health problem that currently lacks effective pharmacological therapy and because the performance of endurance exercise is not a widespread practice among seniors,” conclude the authors of research.

The journal Archives of Internal Medicine published in the same number multiple jobs using a common denominator: they harvest the fruits of older people who spend some time each week to ’sweat shirt. ” Here are the main results:
Cognitive impairment

A study conducted in almost 4,000 Germans aged over 55 years shows that the performance of physical activity with a moderate to high intensity reduces the incidence of cognitive decline after two years. The researchers stress that the decline of mental abilities is one factor that contributes most to the loss of independence of the elderly.
Bone mineral density

A structured exercise program improved, after 18 months, bone mineral density and risk of falls in women over 65 years. The Pope expressed a controlled clinical trial conducted with the collaboration of approximately 250 females. However, this training did not reduce the risk of cardiovascular disease.
Exercise in the residence

A team of French researchers conducted a clinical trial to evaluate the effects of a program of activities tailored to the elderly living in nursing homes and were in very poor shape. As expected, the exercise had a positive impact on their quality of life deteriorated.

The procedure, which could begin human trials within three to six months, involves inserting a breast-shaped chamber, which contains a sample of adipose tissue of women under the skin of the chest. This infiltration is connected to a blood vessel adipose tissue, allowing this to grow and fill the chamber in an estimated period of six to eight months.

From the center, the operations director, Dr. Phillip Marzelle, said today that it is launching a “test prototype” in the coming months that may be implemented through a “proof of principle” with five or six women, so you can see that the body can regenerate its own supply of fat in the chest.

In addition, plans to build within two years a camera biodegradable dissolved when full. “We have proven in several animal models, so we have made sufficient preclinical testing to be sure now to give way to human trials,” he said.

The development of the technique depends on the body’s own behavior and how it is able to fill internal voids, but “also may inject a gel-like substance to stimulate the growth of adipose tissue. “Nature abhors a vacuum, so that the camera itself, because it is empty, has to be completed by the body,” he said.

Women who participate in the tests must have undergone complete or partial mastectomy. The test does not seek to regenerate a whole breast, but to promote growth of adipose tissue in the affected area to demonstrate that the procedure is feasible.

According Marzelle the regenerative procedure could offer women an alternative to traditional breast reconstruction and implants after a mastectomy, but also could help repair other damaged areas of the body. “We hope to move to other organs using the same principle: a camera that protects and contains cells as they grow and resume their normal function,” he said.
