What is axial loading in sports injury?

• A. twisting of the spine due to improper lifting
• B. lateral bending of the neck
• C. compression of the spine that can occur when the top of the head strikes an object
• D. distraction of the spine

Answer: (C)

Axial loading is a compressive force that travels along the spine, pushing from the top down the long axis of the body. In sports, this often occurs when the top of the head or crown strikes a hard object and the force is transmitted straight down the spine. The result is compression of the vertebrae and discs along the spinal column, which can lead to injuries such as vertebral fractures or disc damage. This differs from twisting forces (torsion), which rotate the spine; from lateral bending, which is side-to-side bending; and from distraction, which pulls the spine apart. So the scenario described—a compressive load along the spine initiated by a head strike—best represents axial loading.
