Neural
The 7-9 RPE group trained with significantly higher intensity compared to the 4-6 RPE group.
Higher intensity training may be more effective for strength adaptations.
StrongSupportsmedium confidence
The 7-9 RPE group trained with significantly higher intensity (82.2 ± 5.18 vs. 72.0 ± 4.57% of 1RM, p = 0.002).
