Can older couch potatoes exercise their way to better thinking?

Can older couch potatoes exercise their way to better thinking?

Health
By 2050, there will be 2 billion members of the world over the age of 60 and the ability for those people to stay mentally fit is a big concern. As there are few available treatments for protecting brain health, is exercise part of the answer? If so, what “dose” should the doctor’s prescription pad recommend? Researchers at the University of Miami looked at 98 studies (more than 11,000 people in all) of “couch potatoes” who were all over 60 years old. Based on the Mini-Mental Status Examination -- a “mental fitness” scale used by primary care providers -- people were placed into three categories: healthy adults, those with mild cognitive impairment, and those with dementia. In all the studies, people began to exercise at various intensities for d...

Exercise leads to generation of new heart cells in study with mice

Health
April 25 (UPI) -- Researchers have figured out why exercise is good for the heart, at least in mice: It helps the organ generate more new heart muscle cells.Exercise can even deliver the benefit after a heart attack, according to researchers from the Harvard Department of Stem Cell and Regenerative Biology, Massachusetts General Hospital, Harvard Medical School and the Harvard Stem Cell Institute. The researchers, who published their findings Wednesday in the journal Nature Communications, noted that public health, physical education and the rehabilitation of cardiac patients can help prevent heart failure."We wanted to know whether there is a natural way to enhance the regenerative capacity of heart muscle cells," Dr. Ana Vujic, a researcher at Harvard, said in a press release. "So we dec...

Even short bursts of exercise can reduce Americans' risk of disease and death: Study

Health
Do the national exercise guidelines need a change? That’s a question raised by a new study by researchers at the National Cancer Institute and the National Institutes of Health. Americans are bombarded with mixed messages: Exercise only counts if you do it this way or that way, or for a short time or a long time. Confused, some seem to be willing to sit down on the couch and wait till all the recommendations are straightened out. But with the benefits of exercise so important to health, this study hopes to bring some clarity and reassure people that some is better than none -- and that it is linked to curtailing premature death. "Virtually all [studies] report that higher volume of [moderate or vigorous physical activity, MVPA], whether performed intermittently or in sustained bouts, lo

Study explains how exercise can slow Parkinson's disease

Health
Dec. 22 (UPI) -- Scientists at the University of Colorado Anschutz Medical Campus conducted a study that suggests why exercise can help Parkinson's patients slow the disease's progression.The critical components are the DJ-1 protective gene and the alpha-synuclein protein, according to a news release announcing the study.Humans born with a mutated version of the DJ-1 gene get severe symptoms of Parkinson's disease at a younger age than others. Alpha-synuclein molecules bundle together in the brain to help precipitate neurological decline in Parkinson's patients.In the study from Colorado research associate professor Wenbo Zhou and professor Dr. Curt Freed, mice with Parkinson's were grouped into two categories: those with exercise wheels and those without.After three months, the mice with ...

Aug. 11 (UPI) -- The USS George H.W. Bush carrier strike group has completed the multinational Saxon Warrior 2017 exercise off the coast of the Britain.Participating units from the U.S., U.K., Sweden, Germany and Norway engaged in a 10-day series of carrier strike group training drills involving multiple possible scenarios for future conflicts.It included the commander and staff of the British carrier strike group built around the country's new flagship, HMS Queen Elizabeth, which is currently conducting sea trials."Saxon Warrior was a perfect platform to test how far we've come because we started from scratch," Royal Navy Lt. Cmdr. James Capps said in a press release."We're trying to get in a position that when the Queen Elizabeth comes online, we can operate her as an embryonic carrier s...
