Abstract
Wheelchair trainer apparatus for use with a three-wheel racer wheelchair and which may be effectively utilized as part of a computerized system for physiological training and simulated road race training. A jack supports the wheelchair frame such that the drive wheels just make frictional driving contact with the crest of one of two of the trainer's rollers. Undesired drag, caused by the weight of the wheelchair and its user, is substantially decreased or virtually eliminated, enhancing the trainer's ability to simulate real road conditions.
