Hello, tights can play a protective role, which is equivalent to artificially adding a layer of ligament to the leg. In high-intensity exercise, the risk of ligament or muscle injury can be reduced, so it is meaningful to wear tights to play ball. Few NBA stars don't wear tights. However, I want to say that, generally speaking, the intensity of our play is relatively small and our professionalism is relatively low. Some (all) people who wear tights are trying to show their pride and well-off families, which we commonly call pretending. ?
