The Bottom Line: Squat vs. Stoop Lifting: Which is Safer?
Humantech ergonomist Blake McGowan shares the ground-breaking results from a 2016 study that measured the spinal loads during both squat and stoop lifting in this month’s bottom line video.
The German researchers found:
- Lifting an object from the ground results in significant spinal loading regardless if it was a squat or stoop lift.
- The spinal forces were the same for both. In fact, the forces were 4 percent greater for a squat lift.
