Exercise Can Help Reduce Sick Days

David Nieman

A study published this week in the British Journal of Sports Medicine suggests that regular exercise might have a lot to do with making it to work on a daily basis.

For more than 20 years, Dr. David Nieman and his colleagues at Appalachian State University have studied the effects of exercise, diet, weight, gender and education levels on one’s health. His work shows exercise has the most influence on a person’s health.

“Exercise is probably the most powerful thing you can do to reduce your sick days this winter,”

Nieman said. Nieman is a professor in the Department of Health, Leisure and Exercise Science in the College of Health Sciences at Appalachian State University. He also is director of the university’s Human Performance Laboratory located in the North Carolina Research Campus in Kannapolis.

Research conducted by Nieman, Dr. Dru A. Henson from the College of Arts and Sciences’ Department of Biology, Melanie D. Austin from the Department of Health, Leisure and Exercise Science and Dr. Wei Sha from the Bioinformatics Research Center at UNC Charlotte, has been published in the November online issue of the British Journal of Sports Medicine.

According to a news release from ASU, Nieman and his colleagues have spent more than 20 years studying the effects of exercise, diet, weight, gender and education levels on health. Regular exercise was shown to have the greatest influence.

A brisk walk for 30 to 45 minutes a day increases the number of immune system cells that circulate in the body, Nieman said. These levels may decline within a few hours, but each burst of exercise spells death to a lot of viruses and bacteria.
