The Claim
Increasing the number of lifting repetitions while wearing a passive elastic back exosuit does not eliminate its protective effect against cumulative low back damage, but increasing object weight by 6% completely eliminates that protective effect.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Wearing a passive elastic back exosuit reduces cumulative low back damage during lifting. Doing more repetitions with the exosuit does not remove this protection, but increasing the weight by 6% removes all protection.
See the scientific wording
Increasing the number of lifting repetitions while wearing a passive elastic back exosuit generally does not cancel out its protective effect against cumulative low back damage, whereas increasing object weight by even 6% can fully offset the benefit.
The exosuit pulls on the hips and lower back during bending, which reduces the force on the spine. This lets the back muscles work less hard and prevents tiny tears from building up in the spine's tissues, even when lifting many times. But if the object gets just 6% heavier, the spine feels the same force as without the suit, so the protection disappears.
What the research says
1 studyWearing the back suit lets you lift more times without hurting your back, but if you just make the load 6% heavier, the suit stops helping — exactly what the claim says.
