The Claim

In female participants of Les Mills BODYPUMP classes performing squats, there is no interaction effect between squat depth and load on lower-body muscle activation, indicating that the influence of squat depth and load on muscle activity is independent across the tested conditions.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
26score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

For women doing squats in BODYPUMP classes, how deep they squat and how heavy the weight don’t affect each other when it comes to which muscles are working — each factor works on its own.

See the scientific wording

In female Les Mills BODYPUMP participants performing squats, there is no interaction between squat depth and load on lower-body muscle activation, meaning the effects of depth and load on muscle activity are independent of each other across the conditions tested.

What the research says

1 study
  1. Study: The effect of back squat depth and load on lower body muscle activity in group exercise participants

    The study looked at how deep and how heavy women squat in BODYPUMP classes affect their muscle activity. It found that how deep they squat and how much weight they use work independently—neither changes the effect of the other—just like the claim says.
