Abstract
The belt which normally interconnects the two foot supports of a cross-country ski exercising machine passes around at least one pulley so as to rotate the pulley in an oscillating manner as the foot supports move back and forth. A slotted wheel rotates with the pulley and a photo-detecting unit is mounted on the frame for the exercise machine so as to cooperate with the slotted wheel. The photo-detecting unit includes two photo emitters and two photo receivers. Light from the photo emitters is intermittently received by the photo receivers as the openings in the slotted wheel move between the photo emitters and the photo receivers. This sensor system is capable of determining the extent of movement of the foot supports which, when connected to an information control unit, can provide precise exercise information such as the amount of distance actually covered and the number of calories consumed.
