The high jump was founded in Scotland many years after the olympics started. The first high jumpers used the scissors technique, but later a man by the name of Dick Fosbury approached the jump with a completely different technique. To begin, you start about 20 strides away and begin sprinting towards the bar. As you get closer, during your final four or five steps you begin to run in a curve, allowing the yourself to lean in to their turn and away from the bar. This allows you to create more momentum and get more lift when you come over the bar. You want to make sure your back is curved so that you can clear the bar without any troubles. To do this, you want to make sure that you tilt your head as far backwards as you can, so your body bends even more. This makes your body bend over the bar and allows you to clear it.
