Acute mechanical, physiological and perceptual responses in older men to traditional-set or different cluster-set configuration resistance training protocols.

ABSTRACT: PURPOSE:The aims of this study were to compare mechanical outputs (i.e. power and impulse), physiological (i.e. heart rate) and perceptual (i.e. effort and fatigue) responses in older men to traditional-set or different cluster-set configuration resistance training protocols. METHODS:In a randomized cross-over design, 20 healthy old men (aged 67.2?±?2.1 years) completed four resistance training sessions using the back squat exercise loaded with optimal power loads. Training configurations were: traditional (TRA), three sets of six repetitions with 120-s rest between each set; Cluster-set 1 (CLU1), 24 single-repetition clusters with 10 s of rest after every cluster; Cluster-set 2 (CLU2), 12 double-repetition clusters with 20-s rest after every cluster; and Cluster-set 4 (CLU4), 6 quadruple-repetition clusters with 40-s rest after every cluster. RESULTS:Cluster-set configurations resulted in greater power outputs compared to traditional-set configuration (range 2.6-9.2%, all p [Formula: see text] 0.07 for main effect and protocol [Formula: see text] set interactions). CLU1 and CLU2 induced higher heart rate (range 7.1-10.5%, all p?
