Resumen
Background: Fish oils were studied as ergogenic aids in a number of mixed physical trial designs showingpromising results. However, the heterogeneous purity of the studied supplements, combined with the variety ofphysical tests employed call for more studies to confirm these findings, ideally with standardised supplements. Ouraim was to test a supplement highly concentrated in DHA (DHA:EPA ratio equal to approximately 8:1) on a maximalcycling test to elucidate performance improvements mainly due to DHA.
Methods: A double-blind, placebo controlled, randomised balanced, parallel design, in competitive amateur cyclistswas employed. They were all male, older than 18 years old, with training routine of 2 to 4 sessions per week lasting atleast one hour each. A ramp cycling test to exhaustion with a subsequent 5 min recovery phase was employed beforeand after treatment to analyse aerobic metabolism and lactate clearance after the bout. After 30 days ofsupplementation with 975 mg of re-esteri...
