Walking three times weekly slows decline from peripheral artery disease

03.01.2006


A study in the Jan. 3 issue of the Annals of Internal Medicine shows that walking three times a week, even in an unsupervised exercise program, can significantly improve walking ability and slow progression of peripheral artery disease (PAD). PAD often causes leg pain because of impaired blood flow in the arteries.



The study of 417 men and women, conducted by researchers at Northwestern University Feinberg School of Medicine, indicates that those who walked for exercise three or more times per week had a significantly smaller average annual decline in walking distance and speed than those who walked one to two times per week.

The study was led by Mary McGrae McDermott, M.D., associate professor of medicine, division of general internal medicine, at the Feinberg School.


The researchers also found that only a small proportion of African-American study participants walked for exercise three or more times per week. Previous studies have shown that African-American patients with PAD have greater functional impairment than white patients. Additionally, the prevalence of PAD is higher in African-Americans than in white patients.

"Data from the study suggest that doctors should take steps to encourage African-American individuals to increase their frequency of walking exercise," McDermott said.

Approximately 20 percent of the elderly have PAD. Research has shown that PAD tends to worsen over time, but participation in regular physical rehabilitation programs that include supervised treadmill walking at least three times a week has been shown to improve walking performance and slow the progression of the disease.

However, many patients with PAD have difficulty attending a supervised exercise program because of cost or transportation problems.

Results of the Northwestern study suggest that unsupervised walking exercise, such as that performed at home, also slows progression of PAD.

The researchers tested participants’ physical ability by measuring the distance they could walk in 6 minutes and by observing their ability to get up from a chair unassisted; how well they maintained balance in a standing position; and how fast they could walk over a short distance.

The researchers also asked participants how often they walked for exercise and how long each walking session lasted. Besides showing that self-directed walking for exercise at least three times a week slowed decline in ability to perform physical activities, the study found that participants with the worst PAD at the start of the study were the ones most likely to benefit from a regular self-directed walking program.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
