Depending on your age, just one exercise session may improve the body's ability to overcome stressors by potentially boosting the antioxidant system. These results are part of Tinna Traustadóttir's study published this month in Age, the Journal of the American Aging Association.
In her study, Traustadóttir, an assistant professor of biological sciences, worked with two groups of healthy adults, one was comprised of people aged 18 to 25, and the other was made up of individuals at least 50 years old.
Participants rode a stationary bike rigorously for 45 minutes and returned the following day for additional testing. A blood pressure cuff was inflated and applied steady pressure for 10 minutes followed by a two-minute break. The inflation procedure was repeated three times. Before and after blood samples measured the body's oxidative stress response and changes in antioxidant-related enzymes.
