The present study was to determine the effect of CLA supplementation on subsequent endurance exercise performance after 3 hours of post-exercise recovery. Eight healthy male subjects （aged 22.25 ± 0.73 years） completed a double-blind, crossover trials after 60-mins cycling exercise at 70% VO2 peak oxygen consumption separately by 7 days. They consumed 4.0 g CLA supplementation or placebo with a carbohydrate meal for a 3 hrs recovery following exercise. The subsequent endurance exercise performances （CLA trial 37.3 ± 3.1 mins；Placebo trial 38.4 ± 1.8 trial, p > .05） were no significant improving after CLA supplementation for a 3 hrs recovery following exercise. No differences were found in circulating glucose, insulin, non-esterify fatty acid and glycerol concentrations with CLA supplement compared to placebo supplement. And no differences were found in respiratory exchange ratio, carbohydrate oxidation rate and fat oxidation rate. Therefore, the present study demonstrated that post-exercise oral CLA supplementation could not enhance the subsequent endurance exercise performance in health, untrained, regularly exercising male.
