Full paper summarizedQuality not appraised
What was studied
This randomized trial tested whether fish-oil omega-3 supplementation changed resistance-training adaptations differently in older women and men.
Who / model studied
Fifty older adults participated: 27 men and 23 women, with mean ages near 71 years.
Studied dose & schedule
Participants received 3 g/day fish oil or 3 g/day safflower-oil placebo while performing lower-limb resistance exercise twice weekly for 18 weeks.
What the study found
Fish oil enhanced gains in isometric torque and muscle quality in women, not men. Muscle cross-sectional area, walking, chair-rise and isokinetic-torque responses did not differ by treatment; triglycerides fell in both sexes.
Limitations & context
The sex-specific subgroups were small, and the abstract provides significance tests rather than effect sizes for the key outcomes. Adverse-event results are not reported in the abstract.
