Burn More Calories
For workouts that the researchers described as “somewhat hard,” people on the treadmill burned about 40% more calories per hour (705) than they did on the least-calorie-intensive machine, the stationary bicycle (498). In between were the stair-stepping (627) and rowing machines (606), the cross-country skiing simulator (595), and the Airdyne cycling machine (509), which has handles moved by one’s arms.
“The surprise was that the treadmill came out better than rowing . . . and the cross-country skiing simulator,” said Dr. Martin Hoffman, a physical medicine and rehabilitation specialist who directed the study. It appears in today’s Journal of the American Medical Assn.
