In the context of stored and released kinetic energy during activities such as running, bones provide the least amount of this energy compared to muscles, tendons, and ligaments. This is because bones primarily serve as the structural framework of the body, providing support and protection for vital organs. They are not designed to stretch or store elastic energy like the other options.

Muscles actively generate force and can also contribute to energy storage through their contraction and elongation. Tendons, on the other hand, play a crucial role in energy storage because they are elastic in nature, allowing them to absorb energy during activities like running and then release it effectively. Ligaments offer some degree of elasticity but are mainly involved in stabilizing joints rather than storing kinetic energy.

Therefore, while all these structures play essential roles in movement and support, bones have the least capacity to store and release kinetic energy inherent to explosive activities such as running.
