Muscle force and functional capacity generally decrease with aging in the older population, although this effect can be reversed, attenuated, or both through strength training. Fish oil, which is rich in omega-3, has been shown to play a role in the plasma membrane and cell function of muscles, which may enhance the benefits of training. This study looked at the effect of strength training and fish supplementation on the muscle strength and functional capacity of older women. Forty-five women (average age of 64 years) were randomly assigned to 3 groups. One group performed strength training only for 90 days, whereas the others performed the same strength-training program and received fish oil supplementation (2 g daily) for 90 days or for 150 days (supplemented 60 days before training). The results showed that strength training increased muscle strength in elderly women. The inclusion of fish oil supplementation caused greater improvements in muscle strength and functional capacity.
