Cowley, N, Nicholson, V, Timmins, R, Munteanu, G, Wood, T, García-Ramos, A, Owen, C, and Weakley, J. The effects of percentage-based, rating perceived exertion, repetitions in reserve, velocity-based training on performance fatigue responses. J Strength Cond Res XX(X): 000-000, 2024-This study assessed the percentage-based (%1RM), exertion (RPE), reserve (RIR), (VBT) (a) acute kinematic outputs, perceptions effort, changes neuromuscular function during resistance training; (b) soreness 24 hours after exercise. In a randomized crossover design, 15 subjects completed %1RM, RPE, RIR, VBT condition involving fatiguing protocol followed by 5 sets free-weight back squat bench press at 70% 1 repetition maximum. Subjects returned to assess soreness. Percentage-based RPE allowed smallest volume loads, with %1RM prescription causing be regularly taken failure. Alternatively, RIR greater maintenance volume. Velocity-based had most accurate prescription, all being within 5% intended starting velocity, while prescriptive methods caused train loads that were increasingly inaccurate. method lowest reported values for differential greatest change across session.
