Abstract
The inventive rowing machine detects angular velocity of a pair of oars pulled by an exerciser to move a moving image appearing on a CRT display on the basis of the detection output while controlling the display to change the direction of movement of the moving image in response to pulling of one of the pair of oars when the moving image on the CRT display threatens to run against an obstacle image. Further, physiological condition of the exerciser is detected by the physiological condition detector to reduce the resistance force against rotation of the pair of oars by loading device in response to detection of small reserve strength of the exerciser with respect to the loading device, and to increase the resistance force against rotation of the pair of oars by loading device in respone to detection of large reserve strength of the exerciser with respect to the loading device.
