The induced voltage or the number of rotations is sent to a signal processing device through a transmission module or a wireless transmission module, and the signal processing device converts a resistance segment according to the signal of the induced voltage or the number of rotations to calculate the number of resistance segments. The amount of resistance, one of watts, that the resistance device applies to the fitness equipment. In effect, this creation is through the design of fitness equipment resistance adjustment structure, so that the athlete can produce the change of displacement stroke as long as through simple rotation operation, according to driving resistance device to the flywheel of fitness equipment to apply corresponding resistance, and at the same time, according to the change of the displacement stroke, a resistance segment number can be accurately converted, so as to calculate one of the resistance size and the wattage of the resistance device applied to the fitness equipment.
