ABSTRACT:
A motorless manually operated treadmill exerciser comprising a frame structure supporting a motorless manually operated treadmill assembly and a retardant assembly constructed and arranged to establish a retardant to the continued movement of the endless track of the treadmill assembly when the user desires to slow the walking or running speed or disembark. The retardant assembly comprising a motion transmitting mechanism operatively connected between the leading roller of the treadmill assembly and the fan rotor constructed and arranged to rotate the fan rotor in response to the rotation of the leading roller at an increased speed proportional to the speed at which the leading roller is rotated due to the forwardly facing user walking or running on the upper surface of the upper flight of said endless track, the arrangement being such as to enable the rotation of the fan rotor to create a flow of air entering through a lower air inlet to pass upwardly through openings in an upper guard to impinge on the forwardly facing user with a velocity which is determined by the rate at which the user is walking or running on the upper surface of the upper flight of the endless track.
