Neural
RIR predictions are more accurate when closer to failure, with RIRDIFF values of 2.05 ± 1.73 at 9RPE, 3.65 ± 2.46 at 7RPE, and 5.15 ± 2.92 at 5RPE.
Trainers should encourage clients to gauge their exertion levels closer to failure for more accurate RIR assessments.
StrongSupportsmedium confidence
The RIRDIFF was lower (RPEs were more accurate) closer to failure (RIRDIFF at 9RPE = 2.05 ± 1.73; RIRDIFF at 7RPE = 3.65 ± 2.46; and RIRDIFF at 5RPE = 5.15 ± 2.92 repetitions).
Why this rating
