Description

BACKGROUND OF THE INVENTION

Field of the invention

The present invention relates to running training devices, and more particularly to a treadmill in which a user can accurately simulate the walking track.

Description of the Prior Art

Walking is based on a coordination of the nerves, muscles and bones of the body so that the body can move forward. Even walking or running requires sufficient attention, muscle power and appropriate activity control. A decline in physical function is a common feature of old age and has a significant impact on walking disorders, falls, and the decline in physical health-related quality of life.

In order to assist elderly people in carrying out a rehabilitation training, various training devices have been developed. For example, the JP2002325860 a treadmill including a first leg securing device and a second leg securing device for alternately advancing and retreating to achieve training of the legs. The JP2001309993 discloses a training apparatus in which sliding is performed in a lane so that a pedal alternately moves back and forth. The CN105167959 discloses a multi-functional walk rehabilitation exercise apparatus in which slide blocks are used to alternately move the pedals back and forth, providing pins so that the pedals have a bias. However, the prior art constructions do not allow the pedals to accurately simulate the trajectory of walking or running, resulting in a reduced training effect.
