We need to understand two things, first: Only one type of
bandage can be used. Second: no more than the fingertips.
Language description: Prepare a suitable length of tape, pinch it with your thumb and forefinger, stick it facing the thumb pad, lift the tape, and wrap the thumb. Left hand: the thumb points to the tip of your nose and wraps clockwise; right hand: the thumb points to the tip of your nose and wraps counterclockwise.
Whether the entanglement is from the base of the finger to the direction of the base of the finger or from the tip of the finger to the base of the finger, it is optional and depends on the habit. Personally, I am more accustomed to winding from the base of the finger to the direction between the fingers.
The thickness and layers of the wrap vary from person to person. You can experience it yourself. Because everyone is used to or the width of the tape they hold is inconsistent, it cannot be fully quantified. There is no need to be too serious about the specifics. Try more, including the tightness. After doing it a few times, you will have a good idea. There is no magic and mysterious knowledge here. The same is true for gauze, but it is generally necessary to tie a snap button after winding to prevent the gauze from spreading.
In training, I personally prefer to use gauze and tape together. Because the skin of the fingers sweats. If you only use the tape, it will come loose quickly, if it is a game, you can re-tape it with new tape every time you wait. But it is a little troublesome when training, so I usually wrap it with gauze a few times first, and then fix it with tape on the outside. This works better, and you can adjust the tightness by tightening or loosening. Gauze generally uses inelastic cotton gauze. The gauze can be reused if you're as frugal as I am.
Regarding the use of the two materials together, I have asked some professional athletes, and some people told me that they often wrap the gauze with tape in the game. Generally, if the gauze is not exposed, the referee will not check the tape. Are there any other bandages underneath.
About the choice of tape/adhesive/plaster:
Number one: Inelastic/non-stretchable material. I have also encountered some people who use elastic tape skin stickers to wrap their fingers, but I personally feel that it is not particularly comfortable, because of the elasticity and stretchability, it is easy to cause sliding. Non-elastic tape is recommended.
Second: width, 25mm tape is recommended. The tape that is too narrow cannot be pressed against the edge, and the tape that is too wide may stick to the fingertips.
