The best sports tape to use depends on the circumstances.
To restrict joint movement, use a rigid strapping tape. The size that you need to use depends on the area you are taping. For example, for preventative ankle taping, use Rigid Strapping Tape 38mm or 50mm for large joints. For treatment such as an injured ankle, elbow or finger, use a 25mm or 12.5mm. For treatment on an injured shoulder, knee or foot use a 50mm.
To compress and support joints or muscles, use an elastic adhesive bandage. For strong compression when returning from injury (e.g. sprained knee) use an Elastic Adhesive Bandage 75mm over rigid tape. For initial compression (such as an ankle sprain) use an Elastic Adhesive Bandage 50mm.
