SR=SD/MSL As the rate of stepping increases, a user's foot is exerting force upon the loaded treadle for a lesser amount of time per step. This decreasing time of pressure being applied, with all factors remaining the same, will result in a reduced displacement height for the loaded treadle 12, 14. As such, in order to obtain the desired displacement of the loaded treadle 12, 14 for each step at a given exercise level, the rate of fall of the loaded treadle 12, 14 generally needs to increase. Such rate of fall may be increased, in one embodiment, by increasing the rate at which fluid passes from the hydraulic cylinder 150 attached to the loaded treadle 12, 14 exits, through the hydraulic control valve 152/168, and into the hydraulic cylinder 150 attached to the non-loaded treadle 12, 14 (hereafter, the “fluid flow path”). Therefore, in order to ensure that the depth of fall for a treadle 12, 14 remains the same while the stepping rate increases or decreases, the control system 300 desirably varies the rate at which fluid flows along the fluid flow path. It is to be appreciated that the necessary variations in fluid flow rates may be approximated using mathematical models or based upon actual testing results. Such approximations and/or testing results desirably are also accomplished for a varying range of user weights, effective belt speeds and desired treadle displacement depths. Such approximated or actual testing values may be suitably recorded in a look-up table contained in a database or other storage medium and compared against actual treadle fall rates, as detected, for example, by the encoder, to determine whether to increase or decrease the rate at which fluid leaves a loaded cylinder 150.
