Question

Which of the following statements accurately describes what happens when we stretch our muscles?

a. muscle is elastic and will act like a rubber band when it is stretched.
b. if we stretch our muscles several times the resistance to stretch will decrease and the next day your muscles will be more flexible (less stiff).
c. when we stretch repeatedly over a few days we can achieve a greater range of motion because we can better tolerate the discomfort of the stretch.
d. 30 second hamstring stretches will be sufficient to decrease resistance to stretch and this effect will last at least an hour.

Answer 1

Muscles have the properties of elasticity and extensibility, which allow them to stretch and rebound. Regular stretching over time leads to improved flexibility and range of motion, rather than short-term stretches which provide brief effects.

Step-by-step explanation:

When muscles are stretched, several phenomena occur, which relate to their intrinsic properties. Muscles demonstrate elasticity, which is the ability to return to their original length after being stretched, similar to how a rubber band behaves. This is due to elastic fibers within the muscle tissue. Additionally, muscles have the quality of extensibility, meaning they can extend beyond their normal length.

Multiple stretching sessions over a period of time can lead to increased flexibility. The resistance to stretching may decrease, allowing for a greater range of motion; however, this is not only due to a decrease in muscle stiffness but also an increased tolerance to the discomfort of stretching.

Importantly, while short-term stretches may provide temporary increases to range of motion by reducing resistance to stretch, the duration of this effect can be variable and is often relatively short-lived. It's the regular and consistent practice of stretching that contributes to long-term flexibility gains.
