Just one session of exercise in young people can have protective effects on the body, according to researcher Tinna Traustadottir.
The researchers 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. They found that exercise had the ability to overcome stress by potentially boosting the antioxidant system.
Traustadottir said, "We found that young people got protection from one bout of exercise, and their response to the oxidative stress challenge was lower. The older participants did not have a protective effect after one exercise session, which may be related to impaired cell signaling, a process that could potentially be improved with regular workouts."
The ongoing research aims to identify where in the cell's processes specific age-related changes take place. With better understanding of cell signaling and the beneficial effects of exercise or phytonutrient supplementation, definitive recommendations could be made for improving the body's reaction to oxidative stress, which could lower the risk for many chronic diseases.
The study is published in 'Age', the Journal of the American Aging Association.
