Fish oil supplementation enhances muscle strength gains in resistance training

A recent study published in the Journal of the International Society of Sports Nutrition examined the effects of fish oil supplementation on resistance training induced adaptations. The study involved 20 healthy young adults who underwent a 10-week resistance training program. Half of the participants took a placebo, while the other half took a high dosage of fish oil (4.5 grams per day). The researchers measured omega-3 concentration in the blood and assessed strength gains using the One-Rep-Max method. The results showed that those who took the fish oil supplement demonstrated substantial improvements in absolute and relative strength gains, compared to the placebo group. Absolute strength increased by 17.7% in the fish oil group, compared to 9.7% in the placebo group, while relative strength increased by 17.6% in the fish oil group, compared to 7.3% in the placebo group. These findings suggest that fish oil supplementation can significantly enhance muscle strength gains during resistance training.
