Elasticity in tissues affects movement and function from "summary" of Physics of the Human Body by Richard P. McCall
The elasticity of tissues within the human body plays a crucial role in determining how well we are able to move and function. When we think of elasticity, we often think of materials that can stretch and return to their original shape, like a rubber band or a spring. In the human body, tissues such as muscles, tendons, and ligaments also possess elasticity, allowing them to stretch and recoil as needed. This elasticity is what enables us to move our joints through a range of motion. When a muscle contracts, it generates force that is transmitted through the tendons to the bones, causing movement. The elasticity of these tissues allows them to stretch and store energy during movement, which can then be released to power the next movement. For example, when we jump, ...
