Omega-3 fatty acid supplementation improves performance in trained cyclists
| At a Glance
A new study shows that supplementation with omega-3 fatty acids from fish oil may improve exercise performance in trained athletes by increasing blood flow, nitric oxide release, and maximum oxygen uptake.

There is a small but growing body of scientific evidence supporting the sports nutrition benefit of omega-3 fatty acids. In a new study published in the European Journal of Sport Science researchers evaluated the effects of omega-3 fatty acid supplementation on exercise performance of a small group of trained cyclists.
The study included 13 elite cyclists that were randomly selected to take either 1.3 grams of omega-3 supplements or a placebo daily for 3 weeks. Researcher’s analyzed flow-mediated dilation (FMD, a measure of blood flow and vascular health), pulse wave velocity, serum markers (nitric oxide (NO) and asymmetric dimethylarginine (ADMA), and ultrasound measurements of endothelial function and maximum oxygen uptake both before and after the supplementation period.
Researchers observed a significant difference between the pre- and post-intervention baseline NO levels after the omega-3 supplementation, but not in the placebo group. There was also a positive correlation between the increased concentration of NO and maximum oxygen uptake in the supplemented athletes. The supplemented group also experienced a 5.25% increase in flow-mediated dilation (blood flow) that was not seen in the placebo group.
These findings suggest that an increase in nitric oxide levels resulting from omega-3 fatty acid supplementation may play an important role in cardiovascular mechanisms of adaptation that may enhance exercise performance in trained athletes.

The WTA is USANA Strong. Some of the biggest names in women’s tennis rely on USANA to help keep them on their game. Genie Bouchard is among 170 WTA athletes to know and trust USANA.
But why? Tennis puts a lot of wear and tear on the body. Like many other athletes in other sports, WTA players look to nutritional supplements to fuel their bodies for competition. In today’s day and age, athletes have to be particularly discerning.
But USANA has offered athletes peace of mind. test positive for a banned substance included in World Anti-Doping Agency regulations as a result of taking USANA nutritional products, USANA will compensate that athlete two times their current annual earnings up to $1 million, based on the athlete’s personal level of competition, endorsement, and other income, as well as other factors.
This guarantee is why USANA Health Sciences is the Official Health Supplement Supplier of the WTA. USANA supplements meet the strict requirements that the WADA (World Anti-Doping Association) has set forth.
