The effects of blood flow restriction resistance training on indices of delayed onset muscle soreness and peak power

摘要: BACKGROUND:Low-load resistance training with blood flow restriction (LL+ BFR) attenuated delayed onset muscle soreness (DOMS) under some conditions.OBJECTIVE:The purpose of this study examined the effects of reciprocal concentric-only elbow flexion-extension muscle actions at 30% of peak torque on indices of DOMS.METHODS:Thirty untrained women (mean±SD; 22±2.4 years) were randomly assigned to 6 training days of LL+ BFR (n= 10), low-load non-BFR (LL)(n= 10), or control (n= 10). Participants completed 4 sets (1× 30, 3× 15) of submaximal (30% of peak torque), unilateral, isokinetic (120∘ s-1) muscle actions. Indices of DOMS including peak power, resting elbow joint angle (ROM), perceived muscle soreness (VAS), and pain pressure threshold (PPT) were assessed.RESULTS:There were no changes in peak power, ROM, or VAS. There was a significant interaction for PPT. Follow-up analyses …
