Multi-joint anti-resistance exercise device

Abstract

The invention discloses a multi-joint anti-resistance exercise device and relates to the technical fields of aerospace medicine and exercise rehabilitation. The multi-joint anti-resistance exercise device comprises a waist support, a thigh connecting plate, a shank connecting plate and a foot supporting plate; the side wall of the waist support is connected with a hip joint damper, and the bottomof the hip joint damper is connected with the top of the thigh connecting plate; the bottom of the thigh connecting plate is connected with the top of the shank connecting plate by virtue of a knee joint damper, and the bottom of the shank connecting plate is connected with the foot supporting plate. The multi-joint anti-resistance exercise device disclosed by the invention has the advantages thata low-damping load can be applied to each joint of lower limbs for a long time, and damping provided by the device is overcome without limiting a human body activity range by virtue of active movement of a human body or some special exercise activities, so that the aims of exercising muscles and reducing muscle atrophy of the human body and bone loss are achieved; meanwhile, resistance received by each joint can be controlled, different exercise intensity demands of the human body are met, and exercise damage is avoided.

Description

technical field [0001] The invention relates to the technical fields of aerospace medicine and sports rehabilitation, in particular to a multi-joint resistance exercise device. Background technique [0002] During long-term spaceflight, due to the disappearance of the gravitational load, astronauts no longer need to overcome the effect of gravity when maintaining posture and performing exercises. Long-term exposure to a weightless environment will lead to a series of changes in the human physiological system, resulting in various adverse physiological effects such as cardiovascular dysfunction, muscle atrophy, and bone loss, mainly manifested in reduced orthostatic endurance and exercise capacity. These changes will seriously affect the health and ability of long-duration spaceflight astronauts to complete their missions. Protective equipment currently used in space such as ergometers, treadmills, resistance exercise devices, etc. These measures have a certain protective e...

AI Technical Summary

Problems solved by technology

These measures have a certain protective effect on muscle atrophy, but the phenomenon of muscle atrophy and bone loss of the astronauts after the flight is still very significant, and the astronauts still have difficulties in standing, walking and orienting within a few days after returning

In addition, the existing weightlessness protection exercise measures take up a lot of resources, weight, volume and energy consumption; regular maintenance also takes a lot of time
