In tennis, Gut refers to a type of string made from natural or synthetic materials.
Natural gut strings are made from cow or sheep intestines. They are known for their excellent playability and feel. Gut strings provide a good balance of power and control.
They also absorb shock well, making them easier on a player's arm. Many professional players use gut strings or a combination with other materials.
Gut strings are expensive and less durable than synthetic alternatives. They can also be sensitive to moisture and temperature changes.
