eli5: How does a weightlifting belt prevent injuries?
In: 462
Yes and no.
Yes if used correctly by using a technique called the “valsalva technique”
By breathing with the diaphragm and bracing the core muscles, you can create a hell of a lot of intra abdominal.pressure. which helps support the spine.
The belt exaggerates this technique by acting as a wall to push against when inhaling and bracing.
No if you just tighten it as tight as possible.
Imagine a coke can before you release the pressure. You’ll have a hard time crushing it vertically or even horizontally.
But open it up and release the pressure, and it’s weak, in all directions.
