Verified step by step guidance

Understand the term 'backside mechanics' in sprinting: It refers to the movement of the leg behind the body during the running cycle, which includes the extension phase of the hip joint.

Recall the anatomical movements of the hip joint: Extension involves increasing the angle between the thigh and the pelvis, moving the leg backward. Flexion decreases this angle, moving the leg forward. Abduction moves the leg away from the midline, and adduction brings it closer to the midline.

Analyze the motion during backside mechanics: When the leg moves behind the body during sprinting, the hip joint is in extension. This is because the thigh moves backward relative to the pelvis.

Eliminate incorrect options: Flexion occurs when the leg moves forward, which is part of frontside mechanics. Abduction and adduction involve lateral movements, which are not relevant to backside mechanics.

Conclude that the correct position of the hip joint during backside mechanics is extension, as this aligns with the backward movement of the leg in the sprinting cycle.
