The significance of achilles tendon to bounce;

The first thing to understand here is that the relationship between Achilles tendon and bounce is different from that between thigh and core muscle. The thigh and the core muscle group are mutually determined, and the core muscle group is strong, so the natural thigh is also strong, because if the core muscle group is strong and the thigh is weak, it can't support a strong trunk at all, because the quality of the thigh directly determines the package and protection of the knee. Similarly, a strong thigh must have a strong core muscle group, because if you want to train a good thigh, you must have enough core strength, otherwise it is impossible to have a high level of squat. However, there is no such relationship between Achilles tendon and bounce. If the bounce is good, the achilles tendon must be good, because the achilles tendon must be strong enough to jump high. But the achilles tendon is good, but the bounce is not necessarily good.

Let's analyze the process of bouncing: as we all know, the fundamental source of human bouncing strength is thigh muscles, which is beyond doubt. Therefore, if you want to jump high, the first step must be that the thigh muscles must have a certain level; Secondly, when the thigh exerts force, the force goes down and is transmitted to the ankle and foot surface through the achilles tendon. If the ankle and achilles tendon are not strong enough to bear the force exerted by the thigh, part of the force will naturally be removed, resulting in less force feedback to the ground. So people who bounce well generally have strong ankles; Then, due to the reaction force, the power is transmitted to the buttocks, driving the body off the ground, so the quality of the buttocks is also the key to determining a bounce; Finally, the upper body is stretched to the limit through the swing arm and the extension arm to reach the maximum touch height. From this point of view, the Achilles tendon mainly plays the role of transmission in bouncing, and the real level of bouncing is closely related to thighs, hips and ankles. So you can't say that the achilles tendon is good, and the bounce must be good.

The stronger the achilles tendon, or the stronger the calf muscle, the faster the force transmission speed, and the corresponding running and jumping speed will be very fast. All short-distance athletes, or long jumpers, must have very strong achilles tendons. However, skipping rope is a kind of fitness exercise, and the strength of Achilles tendon has little effect on the usual fitness effect. In addition, the strength of Achilles tendon can be improved by training. Note that we are talking about the strength of achilles tendon here, not its length.
