Wearing a belt during weightlifting increases intra-abdominal pressure by up to 40 percent.
The pressure inside the abdominal cavity pushes on the spine to support it from the inside.
This is how lifting belts can help to protect against back injuries during lifting.
Secondly, wearing a lifting belt reduces the amount of spinal flexion (forward bend at the spine), spinal extension (bending back of the spine), and lateral flexion of the spine (bending side to side), but increases the amount of flexion at the hips and knees.
Thirdly, wearing a lifting belt during squats increases the muscle activity of the quadriceps and hamstrings muscles.
