Description

Underwater treadmill with replaceable handrail

Technical Field

The utility model relates to an underwater running machine for leisure body-building or medical rehabilitation, in particular to an underwater running machine with replaceable handrails.

Background

Running is one of the most common fitness modes of people, can strengthen physique and exercise cardio-pulmonary functions, does not need any apparatus, and has no strict requirement on the field. Running under water is also one of the exercise modes, and because the buoyancy of water reduces the gravity on the body, the stress on joints is greatly reduced, so that the damage of running on all joints of the legs is effectively reduced. Underwater running is also a very suitable restorative exercise for people with joint or muscle injuries. Many professional athletes adopt cross training modes such as underwater running and the like. On the other hand, the resistance of water greatly exceeds that of air, and the consumed heat is greatly increased along with the resistance, so that the water-saving health care pillow is very suitable for people who lose weight.

The running machine is widely applied to occasions such as families, gymnasiums and the like as sports equipment for leisure body building or medical rehabilitation, and on the basis, in order to meet the requirements of users on running underwater, the underwater running machine is also born by the self.
