Physiological basis of trunk support stability training.

Different systems	Main functions
Bone ligament system	The spine is made up of 26 vertebrae that are connected to ligaments around the spine to maintain stability in physical activity. When the body moves, its weight and external momentum are transferred from the spine to the extremities. The soft tissue between the vertebrae increases the flexibility of the spine, thereby increasing the range of motion of the entire spine.
Muscle strength system	Controlling the range of motion and stability of the spine can produce great force. Performing centripetal movement activates muscles and helps control the angle and stability of the spine.
Neural control system	Constantly improving the body’s adaptations can improve control of the limbs. The nerves of the human body can control the adjustment of the trunk muscles in the unstable state and tend to stabilize, thus speeding up the nervous system activity and improving the motor ability.
