What type of stretch is held for a period of time with no motion?

The correct answer, static stretch, refers to a method of stretching where a muscle is elongated and held in that position for a specific duration without any movement. This type of stretching is effective for increasing flexibility and range of motion in the joints. During static stretching, the body is placed in a position that allows the muscle to relax, which can lead to improvements in overall muscle elasticity and decrease the risk of injury.

Static stretching often involves holding a stretch for 15 to 60 seconds, allowing the muscle fibers to gradually lengthen. This contrasts with other types of stretching, such as dynamic stretching, which involves moving parts of your body and gradually increasing reach, speed, or both. Active stretching focuses on using your own muscles to stretch a particular muscle group, rather than relying on an external force. Ballistic stretching involves bouncing or using momentum to push the body past its normal range of motion, which can increase the risk of injury and is generally less safe than static stretching.
