Influence of Varying Proximity-to-Failure on Muscular Adaptations and Repetitions-in-Reserve Estimation Accuracy in Resistance-Trained Individuals
Abstract Purpose The effects of varying proximity-to-failure during a resistance training (RT) program remain undetermined. Hence, we explored the influence of varying proximity-to-failure on muscular adaptations. Methods Young, resistance-trained individuals were randomized to repetitions-in-reserve (RIR)1-4 (n = 16 finished) or RIR1 (n = 15) groups for 10 weeks. Across two 5-week training blocks, RIR1-4 gradually decreased the weekly RIR target…
