Pumping Iron in Your 70s

1 Strength Training for Seniors

Experts advise that maintaining muscle mass in old age is vital for maintaining mobility and managing everyday tasks. Researcher Frank Mayer, U Potsdam, studied the effects of strength training in participants, ages 60 and up and found that a regular program of strength training reduced muscular atrophy, increased muscle strength and helped seniors avoid falls and injuries. Mayer found that, for seniors to increase muscle mass, an intensity of 60-85% of the one-repetition-maximum is required. (This is a measure of the heaviest weight you can lift with one repetition. Researchers recommend that healthy elderly people train three to four times/week. Anyone who begins an exercise program should check with their doctor to ensure that they are able to do so.

Eight Affected, Three Dead

2 Some Joplin Tornado Victims Have Rare Fungus

At least one death among tornado victims in Joplin, Missouri, has been attributed to a rare fungal infection called mucormycosis, reports CNN. Eight tornado victims have been affected by the fungal infection. Three of those eight people have died, but the cause of two of the deaths has not yet been determined. All of those affected by mucormycosis sustained multiple injuries, as well as secondary wound infections. The fungal infection occurs when vegetation, dirt or debris becomes lodged under the skin. Dr. Benjamin Park of the CDC told CNN that the infections can be caused by the tip of a tree piercing the skin. The infection, which doesn't spread from human to human, progresses a few weeks after initial trauma.

New Area of Diabetes Research

3 Study Looks at New Way of Treating Diabetes

Researchers have found that preventing the breakdown of insulin by insulin-degrading enzyme (IDE) they can elevate blood levels in mice as effectively as injecting it or giving medications that increase its secretion by the pancreas. They hope drugs that work this way can be developed for type 2 diabetics whose tissues are insensitive to insulin telling them to take up glucose. Mice with the IDE gene knocked out were observed and found to have an extraordinary ability to decrease their blood glucose levels after eating. But as they aged, the hyperinsulinemia led them to develop the disease they were protected against as their tissues decreased the number of insulin receptors present. Researchers find the results of this study interesting and plan to investigate further.
