Trampolining is a competitive Olympic sport in which athletes perform advanced gymnastics skills while bouncing on a trampoline. Simply jumping on a trampoline and performing basic skills is a beneficial way to increase your level of physical fitness and provide low-impact joint movement, since trampoline skills require extensive movement of your body's joints.
Start Phase
Begin the jump standing in the middle of the trampoline with your legs straight, arms straight out in front and head looking forward. To begin the jump, the shoulder joint is extended, the shoulder girdle is depressed and rotated downward, the elbow joint flexes then extends, the wrist is in ulnar flexion, the trunk and spinal column are slightly flexed, the hip and knee joints are flexed and the ankle joint moves toward plantar flexion.
Top
The body becomes straight at the apex of the jump. The head and neck joint extends, the shoulder joint is in flexion, the shoulder girdle elevates and rotates upward, the elbow joint extends, the wrist joint is in radial flexion, the trunk and spinal cord are extended, the hip and knee joint extend and the ankle joint continues plantar flexion.
Down
In the down phase, you are moving down toward the trampoline bed. The head and neck joint are flexed, the shoulder joint moves toward horizontal extension, the shoulder girdle is depressed, the elbow joint is flexed, the wrist joint is in ulnar flexion, the trunk and spinal cord, hip and knee joints are slightly flexed and the ankle joint is in ulnar flexion.
Safety
Trampolining can be fun and beneficial for joint action and improving your physical fitness, but there can be potentially dangerous aspects if important safety rules are not followed. A qualified supervisor should be in attendance at all times. There should be a qualified spotter on all four sides of the trampoline. No more that one person at a time should jump on the trampoline. The participant should always properly mount and dismount the trampoline. Jump only in the middle of the trampoline.
