AIM
– Evaluate effects of a 3-wk n-3 polyunsaturated fatty acids (n-3 PUFA) supplementation on serum nitric oxide (NO), asymmetric dimethyloarginine (ADMA), ultrasound indices of endothelial function and maximal oxygen uptake of elite cyclists
METHOD
13 cyclists both before and after dietary protocols.
(1) n-3 PUFA 1.3 g twice daily for 3 weeks
(2) placebo
RESULTS
(1) Significant differences between pre- and post-intervention baseline NO levels after n-3 PUFA dietary protocol
(2) Higher post-intervention baseline NO level after n-3 PUFA diet compared with placebo
(3) n-3 PUFA increased baseline NO concentration
(4) Positive correlation between baseline post-intervention NO concentration and maximal oxygen uptake
CONCLUSION
– An increase in NO release in response to n-3 PUFA may play a central role in cardiovascular adaptive mechanisms and enhanced exercise performance in cyclists.
