Fish-Oil Supplementation Enhances The Effects Of Strength Training In Elderly Women

February 1, 2012 Muscles

Muscle force and functional capacity generally decrease with aging in the older population, although this effect can be reversed, attenuated, or both through strength training. Fish oil (FO), which is rich in n–3 (omega-3) PUFAs, has been shown to play a role in the plasma membrane and cell function of muscles, which may enhance the benefits of training. The effect of strength training and FO supplementation on the neuromuscular system of the elderly has not been investigated.

Mild Cognitive Impairment Is Common, Affects Men Most, Study Finds

January 26, 2012 Cognitive Function

Researchers involved in the Mayo Clinic Study of Aging report that more than 6 percent of Americans age 70 to 89 develop mild cognitive impairment (MCI) every year. Also, the condition appears to affect men and those who only have a high school education more than women and those who have completed some higher education. People with MCI are at the stage between suffering the normal forgetfulness associated with aging and developing dementia, such as that caused by Alzheimer’s disease.
