1) Suspension exercise training allows you to train deep stabilizing muscle groups that are seldom practiced during normal exercise training, such as the multifidus and transversus abdominis. 2) Suspension training can improve the coordination of muscle contraction. Suspension closed chain exercise training can activate the "active, synergistic and flexor muscles" at the same time, thus improving the body's motor coordination. 3) Closed-chain exercise training on an unstable suspension rope or using an air cushion can stimulate the sensory-motor organs and improve sensory and motor coordination. 4) Suspension exercise training can correct pelvic problems and spinal deformities in children. For example, hemiplegic children with pelvic lifting on the affected side due to increased tension in the affected lateral flexor muscles can correct the pelvic lifting on the affected side by training the muscle strength of the lateral flexor groups on the opposite side of the trunk spasticity muscles through closed-chain movement training.
