Expansion and supplement:

The factors that affect performance are as follows:

1, power factor. Especially the explosive exertion ability of lower limb muscles puts forward higher requirements for the strength of ankle joint. Because the last force point of standing long jump is the forefoot (even toes), ankle plantarflexion needs considerable strength.

2. Ability to coordinate efforts. Refers to the ability of pelvic muscle group and lower limb muscle group to coordinate exertion (including ankle joint). The correct sign of coordinated exertion is that the hips, knees and ankles can be pushed straight quickly and forcefully, and the upper limbs can swing harmoniously to play the role of belt, collar and lift.

3. The swing of the arm. The standing long jump must swing straight arm, and the greater the swing amplitude, the stronger the action of taking, leading, lifting and pulling. Please pay attention to the observation that anyone who bends his arm and swings will inevitably cause the fluctuation of his upper body, thus affecting the jumping distance.

4. Energy conversion. From standing to squatting, potential energy is converted into kinetic energy, which is equivalent to a certain run-up, which can effectively improve the initial speed and increase the long jump distance.
