In order to reduce the impact force generated by exercise, a suspension backpack is commercially available, which comprises a backpack frame with a sliding rail and a preloaded spring, wherein the backpack has different amplitudes due to different frequencies under forced vibration during exercise, has larger amplitude near the eigenfrequency during walking, has higher frequency during running and jumping, greatly reduces the motion amplitude during running and jumping, and reduces the impact force on shoulders due to the reduction of the motion amplitude. However, when going downhill, the backpack moves upwards relative to the human body when going downwards, and when changing feet, the backpack moves downwards relative to the human body, and the downward movement amplitude is far larger than the movement amplitude when changing feet, so that the vibration balance position of the backpack can shift upwards at the moment, namely the gravity center can shift upwards, and when changing legs, the backpack moves downwards relative to the human body, so that people can lose balance easily, the backpack is forced to move downwards faster, and the downhill speed is out of control.

Secondly, when the mountain is going down, the gravity action direction is consistent with the movement direction, gravitational potential energy is easily converted into kinetic energy, so that the mountain-down speed of a person is faster and faster, and most of falling injuries are generated in the mountain-down process according to statistics, so that the speed control is very necessary in the mountain-down process.
