Hang style and running style are the two most common jumping styles.
Most men take a run-up of 45-50 metres, and when they hit the take-off board their speed is around 40 km per hour - equivalent to top 100 sprinters.
Women have a slightly shorter run up.
The pressure on the leg at the time of take-off is approximately 10 times the body weight of the athlete.
