This type of application is called an inhibition technique. The key for using it is to use the anatomy! Remember, the tape is specifically made to pull on itself. That is what the weird spirals and shapes are when you look a the back of the tape. When trying to inhibit the muscle, you want the tape to move from the muscle insertion to origin so that when the tape pull on itself, it results in an eccentric pull (eccentric = lengthening of the muscle). This is ideal for trying to diminish the contraction which will allow for rest and more importantly recovery.
