Approach

The objective of the approach is to gradually accelerate to a maximum controlled speed at takeoff. The most important factor for the distance traveled by an object is its velocity at takeoff - both the speed and angle. Elite jumpers usually leave the ground at an angle of twenty degrees or less; therefore, it is more beneficial for a jumper to focus on the speed component of the jump. The greater the speed at takeoff, the longer the trajectory of the center of mass will be. The importance of a takeoff speed is a factor in the success of sprinters in this event.
The length of the approach is usually consistent distance for an athlete. Approaches can vary between 12 and 19 strides on the novice and intermediate levels, while at the elite level they are closer to between 20 and 22 strides. The exact distance and number of strides in an approach depends on the jumper's experience, sprinting technique, and conditioning level. Consistency in the approach is important as it is the competitor's objective to get as close to the front of the takeoff board as possible without crossing the line with any part of the foot.
Inconsistent approaches are a common problem in the event. As a result the approach is usually practiced by athletes about 6-8 times per jumping session. The last two strides The objective of the last two strides is to prepare the body for takeoff while conserving as much speed as possible. The penultimate (second to last) stride is longer than the last stride. The competitor begins to lower his or her center of gravity to prepare the body for the vertical impulse. The final stride is shorter because the body is beginning to raise the center of gravity in preparation for takeoff. The last two strides are extremely important because they determine the velocity with which the competitor will enter the jump; the greater the velocity, the better the jump.
