Thought this was an interesting study comparing front to back squats. Nate Green mentioned this study in one of the articles here. Interested to see people's opinions.

I think they should have done the study on Olympic weighlifters.


#3

It sounds like a bad study, considering individuals only squatted to parallel.


#4

Looked like a good study to me. The only surprise I see is low back activation was lower with Back Squats. Everything else was as I would guess.

You have to keep your lower back tighter, relative to back squats, in front squats to stay up right.

When I Front Squat my torso is almost completely upright. When I BS there’s much more torso lean which, I would think, would activate my lower back more.

My question is, how do you front and back squat once a week for a year and have a 90% body weight 1rm?

Average 1rm for the group was 135??

staying upright should relieve stress from the lower back. Just like a GM emphasizes lower back more than a back squat.

The author of the article misquoted the study. The subjects did their test back and front squats at 70% of the 1RM which was about 90% of their bodyweight for the back squat and around 70% of their bodyweight for their front squat. In other words, the subjects’ back squat 1RM was ~1.15X bodyweight whereas front squat 1RM was ~1X bodyweight.

Still pretty weak by most standards, but then again its probably hard to find a large sample size with about the same lifting experience and relatively close strength levels.
