Why the study?
Low-load resistance training with blood flow restriction attenuates delayed onset muscle soreness under some conditions, prompting evaluation of reciprocal concentric-only elbow flexion-extension actions at 30% of peak torque on indices of DOMS.
Does low-load resistance training with blood flow restriction induce delayed onset muscle soreness in untrained women?
Does low-load resistance training with blood flow restriction induce delayed onset muscle soreness in untrained women?
Low-load concentric-only resistance training with blood flow restriction does not induce delayed onset muscle soreness in previously untrained women.

May attenuate DOMS after low-load elbow training in novices; hypothesis-generating and requires larger confirmatory trials.
BACKGROUND: Low-load resistance training with blood flow restriction (LL [Formula: see text] 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 [Formula: see text] SD; 22 [Formula: see text] 2.4 years) were randomly assigned to 6 training days of LL [Formula: see text] BFR ([Formula: see text] 10), low-load non-BFR (LL) ([Formula: see text] 10), or control ([Formula: see text] 10). Participants completed 4 sets (1 [Formula: see text] 30, 3 [Formula: see text] 15) of submaximal (30% of peak torque), unilateral, isokinetic (120[Formula: see text]s[Formula: see text]) 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 indicated PPT increased for the LL [Formula: see text] BFR condition (Day 5 [Formula: see text] Day 2), but did not decrease below baseline. The results of the present study indicated LL [Formula: see text] BFR and LL did not induce DOMS for the elbow extensors in previously untrained women. CONCLUSION: These findings suggested LL [Formula: see text] BFR and LL concentric-only resistance training could be an effective training modality to elicit muscular adaptation without inducing DOMS.
