Do low and high RIR resistance training produce the same changes in motor unit activity during sustained isometric contractions?

RIR & Motor Unit Activity1 min readUpdated June 2, 2026

What the Evidence Shows

We analyzed one assertion on how low and high RIR resistance training affects motor unit activity during sustained isometric contractions, and the evidence we’ve reviewed so far suggests that both approaches lead to similar changes in the electrical signals from motor units when contracting at 30%...
