Myth: Polyunsaturated fatty acid supplements improve muscle strengthening from resistance exercise
Truth: Long-chain n-3 polyunsaturated fatty acid (PUFA) supplementation has been linked to improving the effects of resistance training on muscle mass and function, however, this association has only been seen in women. Using results from a study published in the American Journal of Clinical Nutrition, evidence shows that PUFA supplements can only help older women who perform resistance training exercises – not men.
In women, PUFA supplements have been shown to cause an increase in maximum torque following an 18-week period of resistance exercise, in comparison to women who were taking a placebo and also performing resistance exercise for 18 weeks. This effect was not seen in men also enrolled in the study; instead, researchers learned that there were no differences between the group of men taking PUFA supplements and those taking placebos during 18 weeks of resistance exercise.
