Inline skating as a form of exercise is as beneficial as running or cycling, according to Dr. Carl Foster, associate professor of medicine at the University of Wisconsin Medical School and coordinator of sports medicine and sports science for the United States Speed Skating Team. A fitness study completed for Rollerblade, Inc. in 1991 measured how inline skating compares as a form of exercise to running or cycling, in terms of caloric expenditure, as well as aerobic and anaerobic benefits.
