Which factors can influence flexibility?

Flexibility is influenced by a variety of factors, and the correct choice highlights key contributors. Age is significant because as individuals grow older, the elasticity of muscles and tendons tends to decrease, leading to reduced flexibility. Gender also plays a role, as studies generally indicate that females often have greater flexibility than males due to differences in muscle and connective tissue composition. Temperature is essential because warm muscles are more pliable, making it easier to stretch and enhance flexibility. Finally, muscle length is directly related to flexibility; longer muscles generally allow a greater range of motion.

Together, these elements create a comprehensive picture of how various physical and biological characteristics interact to affect an individual's flexibility. Understanding these factors can help fitness professionals design better training programs tailored to improving flexibility based on the client's specific needs and circumstances.
