Omni-directional running exercise instrument

The invention discloses an omni-directional running exercise instrument. The omni-directional running exercise instrument is characterized in that a running platform is provided with a central platform and an annular omni-directional running platform, wherein the central platform is located in the dead center of the running platform and can allow a person to stand as for the size, the omni-directional running platform is integrally connected with the periphery of the central platform, the upper surface of the omni-directional running platform is densely covered with a plurality of rolling elements, and the rolling elements can roll in situ and can roll in the direction facing the central platform; the running platform is provided with a human body support frame, the human body support frame comprises support arms and a human body support assembly, the lower ends of the support arms are fixed on the outer edge of the omni-directional running platform, and the human body support assembly is located above the central platform and fixed at the upper ends of the support arms; the running platform is provided with a data interaction header, and the data interaction header is provided with a processing controller and a signal transceiving unit; the running platform is provided with a sensor for acquiring the speed. The omni-directional running exercise instrument overcomes the direction limit of a runner on a running machine and provides an optimal implementation way for virtual simulation of running exercise.
