Influencing factors of field long jump;
1, power factor. Especially the explosive force of lower limb muscles, put 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.
