Antioxidants May Help Maintain Muscle Function

At a recent meeting of the Gerontological Society of America, researchers described a new study that found diets rich in antioxidants to be potentially helpful for preserving the muscular strength of older adults. The scientists examined the long-term eating patterns of more than 2,000 persons in their seventies. In addition, they recorded the subjects’ handgrip strength at baseline, and then again after the passage of two years. (For more news about grip strength, see the following article.)

A significant positive association was found between muscle strength change and the consumption of vitamins C and E. This was true even for subjects who started out with low levels of strength. Researchers don’t think it is effective to take high-dose vitamin C and E supplements, which in some cases can be unhealthy. Instead, these findings point to the value of following a well-balanced diet that is high in nutritious fruits and vegetables.


At Hand: An Important Predictor

A simple tool that is used routinely by many older adult fitness professionals may hold more significance than was previously realized by the health and fitness community. That device, a staple at senior wellness fairs, is the hand dynamometer, which measures grip strength.

In addition to functional fitness implications, it now appears that diminishing grip strength may also indicate an increased risk for impending mortality. Researchers have found that decreased handgrip strength in the very elderly is associated with a higher risk for death.

A new study published online by the Canadian Medical Association Journal identifies waning handgrip strength as an important indicator of increased risk for death in octogenarians, as well as in persons beyond their eighties. The subjects of the study were 555 elderly men and women residing in the Netherlands. Their handgrip strength was recorded at age 85, and then again at age 89. Three important findings emerged:

  • Low handgrip strength at ages 85 and 89 was connected with an increased risk for death from all causes;
  • So was a significant decline in handgrip strength over time; and
  • With aging, the association between grip strength and the risk for death increases.
  • Does muscle strength directly affect mortality risk, or are other important variables more closely involved? Scientists don’t yet know the answer to that question. Researcher Dr. Carolina Ling and her colleagues at the Leiden University Medical Center say that the link between muscular strength and the risk for death is not well understood. Additional research should be undertaken.

    Even so, the study’s authors concluded that assessing handgrip strength can help health-care professionals target elderly patients who are at risk. Steps to preserve muscular strength can then be employed in order to improve those individuals’ probability for survival.
