Flexibility in health-related fitness includes which types of stretching?

• A. Dynamic and static stretching
• B. Cardio and strength
• C. Ballistic
• D. Isometric

Answer: (A)

Flexibility in health-related fitness is developed through stretches that lengthen muscles and improve range of motion. The main types are dynamic stretching, which moves joints through a full range of motion with control as part of a warm-up, and static stretching, which holds a stretch to gently lengthen a muscle, typically for 15–60 seconds. Ballistic stretching uses bouncing motions and can increase injury risk, so it’s not a standard method for flexibility. Isometric stretching involves holding a muscle in a contracted state and is more about strength and stability than flexibility alone, so it isn’t categorized with the classic stretching types for flexibility. Therefore, combining dynamic and static stretching best represents flexibility training.
