Which property describes the resistance of tissue to external loading?

The property that describes the resistance of tissue to external loading is stress. In the context of biomechanics and athletic training, stress refers to the internal resistance that a material displays when subjected to an external force. It is defined as the force applied per unit area of the tissue. This concept is crucial for understanding how various tissues in the body, such as muscles, tendons, and ligaments, respond to different types of physical stress during activities like sports and exercise.

Understanding stress allows athletic trainers to evaluate how much force a tissue can handle before experiencing damage or failure. This principle is vital for developing training programs that promote strength without causing injury, as well as for rehabilitating injuries by assessing the stresses that already damaged tissues can tolerate.

Other terms, such as elastic limit, strain, and yield point, play important roles in tissue mechanics but describe different concepts. The elastic limit refers to the maximum amount of strain a material can withstand while still returning to its original shape. Strain measures the deformation that occurs in a material in response to stress, and the yield point indicates the stage at which a material begins to deform plastically and will not return to its original shape. Understanding these terms in conjunction with stress helps provide a comprehensive view of how tissues behave under load
