The findings regarding back squat strength improvements between resistance training with 4-6 RPE and 7-9 RPE are statistically inconclusive.
Further research may be needed to clarify the effectiveness of different RPE levels in resistance training.

More from this paper
- Both training programs (4-6 RPE and 7-9 RPE) resulted in increases in back squat one-repetition maximum (1RM), with the 4-6 RPE group increasing by +13.78 kg and the 7-9 RPE group increasing by +18.05 kg.Strong
- Trivial between-group effect sizes were observed when comparing the strength gains of the 4-6 RPE group to the 7-9 RPE group (g = -0.12).Strong
