Omega-3 fatty acids and exercise: a review of their combined effects on body composition and physical performance

Omega-3 (n-3) fatty acids, and the long-chain n-3 derivatives eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in particular, have been extensively researched for their nutritive effects. Among their many purported benefits, n-3 acids have been implicated as positive mediators of cardiovascular health and body composition. It has therefore been speculated that supplementation may enhance the beneficial effects of physical activity, potentiating greater reductions in body fat and improvements in exercise performance. This paper has three objectives: first, to assess the theoretical basis for a synergistic ef-fect when n-3 supplementation is combined with exercise; second, to review the literature as to specific findings on the subject and third, to make relevant conclusions and recommendations for future research.
