Neural
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.
Both training intensities can effectively increase squat strength, allowing trainers to choose based on individual preferences or goals.
StrongSupportsmedium confidence
Increases in 1RM back squat were observed in both groups (4-6 RPE: +13.78 kg [4.94-22.62], 7-9 RPE: +18.05 kg [9.66-26.43])
