Holding gentle stretches for up to 10 minutes can improve which of the following?

• A. Tendon flexibility
• B. Muscle strength
• C. Cardiovascular endurance
• D. Joint proprioception

Answer: (A)

Long-duration static stretching increases the length and compliance of the muscle–tendon unit through viscoelastic creep under a gentle, sustained load. When you hold a stretch for several minutes, the connective tissues, including the tendons, gradually yield, allowing a greater passive stretch and thus greater flexibility. This change in the tissue mechanics is what you’re targeting with extending holds, not muscle strength, aerobic fitness, or joint position sense. Strength comes from resistance training, cardiovascular endurance from aerobic activity, and proprioception from neuromuscular balance and sensory training. So, holding gentle stretches for up to 10 minutes best improves tendon flexibility.
