The term that represents the transfer of energy across joints to support voluntary movement is the kinetic chain. The kinetic chain concept illustrates how different segments of the body work together, transferring energy from one joint and muscle to another during movement. This interconnectedness is essential for efficient movement patterns, as it ensures that forces generated by one part of the body can be effectively transmitted through the joints and into the next segment, enhancing overall performance.

In the context of physical activity or strength training, understanding the kinetic chain is crucial for personal trainers to create effective programs that optimize client performance while preventing injuries. Proper kinetic chain functioning can help with activities ranging from simple tasks, like walking, to complex athletic movements, emphasizing the importance of stability and mobility at each joint.

The other terms, while relevant to movement and mechanics, do not specifically define the process of energy transfer across joints in the same manner as the kinetic chain. For instance, force transfer refers more to the specific application of force rather than the holistic system of joint and segment interactions. Energy continuum typically pertains to the various energy systems utilized during physical activity, while joint dynamics might describe the movement characteristics of joints but does not encompass the broader context of energy transfer in movement patterns.
