Final answer:
Early kicking is characterized by leg action, with abductor muscles facilitating the movement of the leg away from the body and allowing for significant transfer of energy during a kick.
Step-by-step explanation:
The action characteristic of early kicking is primarily associated with leg action. Kicking involves a series of coordinated movements, typically initiated by the muscles in the legs. When considering muscle terminology, the muscles that move the leg away from the body are known as abductor muscles. This movement is opposed by adductor muscles, which bring the leg towards the body. Additionally, the rotational kinetic energy delivered to the lower leg is a key factor in the force of the kick, as it allows for the transfer of energy to an object, such as a ball.
