Trampolining was first introduced at the Olympics in 2000, and like any sport, trampolining can be very dangerous if the proper precautions are not taken. According to Spine Universe, the number of patients admitted to an emergency room with trampoline-related injuries has increased between 30 and 45 per cent since 1998. To prevent these injuries, ensure the trampoline is properly assembled before you use it and read the owner's manual before you begin practicing moves such as the backdrop.
Stand straight up with your chest and hips slightly pushed out. Stand about 1.2 m (4 feet) from the centre of the trampoline.
Jump about 30 cm (1 foot) off the surface of the trampoline and extend your arms above your head as much as you can. Your body should form a slightly concave line while in the air, which will allow you to land on your back.
Extend your legs 90 degrees to your torso just before your back lands on the surface of the trampoline. Your body should form an L shape in this position.
Keep your arms extended straight up above your head and your legs at a 90 degree angle as your back lands flat on the surface of the trampoline.
