Elastic and inelastic. I only know the function of inelastic. According to the teacher, as a professional athlete, muscle strength is greater than ligament endurance, and it is common for excessive exercise to cause ligament strain (cracking), so rest and ice treatment are normal. But as a professional athlete, you must continue to compete according to the contract, otherwise the club and sponsors will have opinions. Therefore, inelastic adhesive tape is used to replace the injured ligament to fix the joint and limit the range of motion of the joint. It plays a temporary protection role and ensures that the injury will not get worse before treatment.

According to observation, elastic belt is often attached to muscles rather than joints. Therefore, personal speculation is that the elastic function of some muscles can be replaced or enhanced by the elastic force of elastic belt, which can slow down muscle fatigue and improve the output efficiency of muscle strength. If so, the compensation possibility of muscle injury and insufficient elasticity cannot be ruled out.

The normal use of bandages and figure-8 bandages will cause the ankle joint to be too big to put on shoes. Using adhesive tape, the final thickness is only the thickness of socks, so you can wear shoes normally.
