A University of Georgia study found low-intensity aerobic exercise can boost energy levels and reduce fatigue. The study included 36 healthy, but sedentary, young people who reported persistent fatigue.
One group of volunteers did low-intensity aerobic exercise for 20 minutes, three times a week for six weeks. Their fatigue levels decreased by 65 percent.
Another group performed moderate aerobic exercise for the same amount of time. They had a 49 percent drop in fatigue.
Doctors say moderate exercise may be too much for those who are already experiencing fatigue, so it's better to begin exercising at a slower pace.
The findings are published in the journal Psychotherapy and Psychosomatics.
