ABSTRACT:
A gymnastic pedaling apparatus comprises a base provided with a projected portion having a horizontally arranged pivot shaft on which two pedals are movably mounted. A damping adjusting device mounted on the base is composed of two bottom frames, an adjusting frame provided with two connecting rods and an adjusting theaded rod, a guide member pivoted with the adjusting frame, and a hydraulic cylinder having one end fastened to the base and another end fastened pivotally to the guide member. The damping of the gymnastic pedaling apparatus is effected when the two pedals are made to move upwards and downwards. Such upward and downward motions of the pedals trigger the rotation of the adjusting frame, which is subsequently forced to make an angular displacement so as to activate the piston rod of the hydraulic cylinder to effect a damping effect of a forward motion or a backward motion.
