Women bad "lifters"
When you lift, you use knee, hip, and lower back. Women tended to use each joint separately, one after the other.
This put most of the stress on the lower spine. YOW!
The study participants, 30 men and 15 women, were asked to transfer 24 boxes, 33 lbs each, from one pallet to another, then back, up to 5 times in 30 mins.
Special cameras analyzed this.
Men and women moved their joints in a sequential pattern--knees, hip, back--but the men delayed less on each phase. The men used more of a squat lift--back straight.
The takeway--men may be able to do this quicker because of upper body strength, who knows.
Anyhow, in my opinion, men should so the heavy lifting, women the thinking.
Kidding, kidding--don't hit.
