摘要:
Arm wrestling apparatus employing two opposed hydraulic dampers to provide resistance. The apparatus has a base and a lever pivotally mounted to the base. Hydraulic circuitry of the dampers may be controlled to vary resistance, and is employed to operate a gauge indicating force of effort. In an alternative embodiment of the invention, two novel arm wrestling devices are employed remotely from one another. Each device is provided with a video display. Radio, telephone or other links connect the displays of the two arm wrestling devices so that observers at either location may monitor a competition between two persons, one at each location.
