Answer
Plane: The plane in which running takes place is the sagittal plane, as it divides the body into left and right halves, allowing forward and backward movement.
Axis: The axis associated with running in this plane is the transverse axis, which enables the rotational movement of the limbs during the action of running.

Answer
Class: The class of lever operating at the ankle during running is a class 1 lever. In this system, the fulcrum is located between the effort applied by the muscles (pulling on the heel) and the load (the weight of the body).
