HIGH JUMP EVENT
The high jump is a track and field event in which competitors must jump unaided over a horizontal bar placed at measured heights without dislodging it. In its modern most practiced format, a bar is placed between two standards with a crash mat for landing. The high jump is a sporting event that takes place in the competitions of the Olympic program. It is a sport that belongs to athletics, in which the athlete makes a jump preceded by a race to reach the height.

The high jump consists of three phases. These phases are the approach phase, the takeoff phase, and the flight phase.
1. Approach
– The approach begins as a straight line sprint that eventually turns into a curve. Most athletes have an approach run that covers eight to twelve strides. The approach run is extremely important for performance in the high jump. It increases the athlete's horizontal velocity, which will eventually be used for the take off.
2. Take Off
– The plant and takeoff begin during the approach. The athlete's second-to-last stride during the approach run (called the penultimate stride) will be longer than the last stride and will begin the lowering of the athlete's center of gravity by flexing the knee. During the last stride, the foot is slapped down and the knee is extended. The athlete is leaning backwards so that the hips are ahead of the shoulders. The leg during the last stride acts as a lever while the other leg is swung forward and up allowing the athlete to jump.
3. Flight / Landing
– Success in the flight phase is dependent by the athlete's ability to exert force against the ground during the takeoff. This means that as the athlete leaves the ground during the takeoff, they must make sure their body is out of the way of the bar while they pass over it. This is done by arching the back after the head and shoulders have cleared the bar, which lifts the hips.
