Qualitative Analysis of the Preparatory Phase within the Standing Vertical Jump Qualitative Analysis of the Preparatory Phase within the Standing Vertical JumpDuring standing vertical jump, there are some phase of preparatory activities which are involved. These activities include the movements of the ankle, knees, hip, shoulder joints and body trunk. During the initial position of the student, all the muscles and joints in the ankle, knees, shoulder joints, and body trunk are at rest, there is no observable change in their position. The figure 1 below shows the original position of the ankles before the beginning of the jumping process. The table at the appendix shows an anatomical analysis of the preparatory stage during the standing vertical stage. Movement of ankle during the beginning of the preparatory phase During the beginning stages of standing vertical jump, the bones of the ankles which are involved during this stage are the tibia and calcaneus, these bones together form a modified joint.Pronation is very vital in the ankle as it helps to transfer forces forward and towards the midline of the bones, this transfer will enable the body to achieve motion during jumping up. During this stage still, the medial arch will flatten and heals rolls inwards. At this point, the jumper feels so light and can easily lift himself or herself off the air[CITATION Ani13 \p 178 \l 1033 ]. During 2

Qualitative Analysis of the Preparatory Phase within the Standing Vertical Jump jumping, the jumping jack of the ankle contracts the Dorsiflex, dorsiflexor and Tibialis Anterior muscles to open the modified joints of the ankle. This forkful action will hence make the jumper to jump easily as seen in the figure. Fig 2: Shows a jumper involvement in her ankles before jumping. Movement of knee during the beginning of the preparatory phaseThe knee jump is commonly known as calisthenics or sometimes referred to as plyometric, during the standing vertical jump, the knee plays a very important role by the contraction of the vastus lateralis, vastus medialis, and Rectus femoris which is achieved by extensions of these muscles. The contraction of the muscles of the knees will pull up of the legs and thighs hence the whole body, this will hence result in the movement of the whole sagittal plane up. Basically, knees contribute movement by relaxation and contraction of muscles. After this, there will be a lot of power developed which will enable movement of the body[CITATION Joh15 \p 195 \l 1033 ]. Movement of knee during the beginning of the preparatory phaseFor any standing vertical jump, there is two motion which will be involved in the movement of the body attributed by the hips; extension and flexion. For the standing vertical jump, hips flexion (which is pushing hips back into the loaded position) plays a greater role in 3
