The effects of fish oil and isoflavones on delayed onset muscle soreness
Lenn J, et al
Published in Medicine and Science in Sports and Exercise
Methodology
Randomized, double-blind, placebo-controlled trial in untrained adults supplemented before and after an eccentric exercise bout inducing delayed onset muscle soreness; outcomes were soreness ratings, isometric strength and serum creatine kinase.
Key Findings
Neither fish oil nor isoflavone supplementation reduced muscle soreness, strength loss or creatine kinase elevation after eccentric exercise; soreness followed the same time course as placebo.
Conclusions
Fish oil and isoflavones were not effective in ameliorating delayed onset muscle soreness.
Limitations
Small sample (n=22), single exercise bout, and untrained participants; underpowered to detect small effects.
Supplements Studied
These data indicate FO or ISO, at the doses supplemented, were not effective in ameliorating DOMS with the above-cited protocol.
