For the training of the explosive power of the calf, the following methods can be adopted: 1, you can take continuous frog jumping exercise, requiring patients to first find a specific point on the ground, and then start with this, continuous frog jumping forward, generally in groups of ten jumps, continuous jumping three groups. 2, you can practice touch height exercise, for example, you can find a relatively high basketball frame, or a single bar, and then stand underneath, continuous Longitudinal jumping, requiring each time you jump up to touch a specific height. Generally 10 times as a group, three consecutive groups. 3, you can do related weight exercise, such as you can first carry a specific weight of dumbbells, and then practice pad up the heel. The patient can also practice ankle joint activities under resistance conditions, for example, the patient can find a thick rubber band, pocket the forefoot, and then continuously use the forefoot to stomp on the rubber band. In this way, you can gradually increase the explosive power of the lower leg.
