Which factor does NOT limit flexibility?

Flexibility describes the range of motion around a joint and is influenced by several anatomical and physiological factors. While muscle and tendon condition, body weight, and bony structure all play significant roles in determining flexibility, environmental conditions do not directly impact an individual's inherent flexibility.

Muscle and tendon condition relates to the elasticity and length of these tissues; tighter muscles and tendons can restrict movement while more pliable ones enhance flexibility. Body weight can influence how easily a person can move and their overall range of motion, with excessive weight sometimes being a barrier to flexibility. Bony structure also has a foundational role because the shape and configuration of bones at a joint dictate the extent of movement possible.

Environmental conditions, such as temperature and humidity, can lead to temporary variations in muscle performance and warmth, impacting flexibility on a short-term basis. However, these are not fundamental limitations intrinsic to an individual’s anatomy or physiology. Therefore, environmental conditions do not constitute a primary factor that limits flexibility in the way that muscle condition, body weight, or bony structure do.
