Which common activity among athletes can significantly increase the risk of a herniated disc?

Heavy lifting is an activity that can significantly increase the risk of a herniated disc among athletes due to the intense pressure it places on the spine. When lifting heavy objects, especially with improper form or technique, the spine is subjected to excessive strain. This can lead to the displacement of the intervertebral discs, causing them to bulge or rupture, which is known as a herniated disc.

During heavy lifting, the muscles that support the spine may become fatigued, leading to a decreased ability to stabilize the lumbar region effectively. This can result in an increased likelihood of injury if the individual attempts to lift more than they are prepared for or without adequate support. Furthermore, repetitive heavy lifting can exacerbate wear and tear on the discs, making them more susceptible to herniation over time.

Other activities like running, swimming, and cycling typically pose a lower risk for herniated discs when practiced with proper technique, as they often involve lower levels of axial load on the spine compared to heavy lifting.
