Abstract
A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.
