What is the stipulation regarding medical tape used during competitions?

The correct answer highlights that two layers of medical tape are permitted around the thumb during competitions. This rule is in place to ensure that athletes are allowed some level of support for their thumbs while maintaining a fair competition environment. The use of tape is primarily focused on enhancing grip and preventing injuries rather than providing significant lifting advantages.

When using tape, the regulations specify that only a limited amount is allowed to avoid any potential unfair advantage that excessive taping could provide. Therefore, allowing two layers specifically for the thumb strikes a balance between safety and competition integrity.

In powerlifting, the rules governing equipment and supportive materials like medical tape are designed to prioritize the lifter's health while also upholding the standards of the sport. This approach helps to maintain a level playing field among competitors.
