What is active (unassisted) stretching?

1. A form of static stretching only

2. A method performed with external assistance

3. Stretching performed alone using concentric contraction

4. A technique that combines weights with static stretches

The correct answer is: Stretching performed alone using concentric contraction

Active (unassisted) stretching refers to a stretching technique where an individual uses their own muscle strength to hold a position without external assistance. This method involves concentric contraction, where the muscles used to achieve the stretch are actively engaged. For example, raising a leg to stretch the hamstrings while keeping the other leg on the ground utilizes the strength of the muscles to maintain the stretch position. This type of stretching is beneficial because it helps improve flexibility and range of motion while engaging the muscles actively. It contrasts with passive stretching, where an external force—such as a partner or equipment—is used to aid in the stretch. Active stretching can contribute to muscle conditioning and may also enhance neuromuscular control. In contrast to the other options, which describe different stretching techniques that either involve passive assistance or do not emphasize the active engagement of muscles, the focus of option C clearly defines active (unassisted) stretching and highlights its unique characteristics.
