Clustering vs Multi-Sets Method in Resistance Training: Effect on Heart Rate Variability

Abstract

The aim of this study was to analyze the effect of two different methods (clustering and multi-sets) on resistance training on heart rate variability (HRV) in young adults. A total of 31 volunteers were randomly divided into three groups: clustering (GCL), multi-sets (GMS) and control group (CG). Group and time interaction was identified (F(3, 28) = 36.71, P < 0.01), with reduction in CG (P = 0.01) and increase in GCL (P = 0.01) and GMS (P = 0.01). It was concluded that both clustering and multi-sets enhanced HRV after 8 weeks of resistance training in trained young adult males.
