In a double-blind trial physical education students and lecturers (8 experimental and 8 placebo) were pre-tested for chest and grip strength, predicted VO2 max using an incremental bicycle ergometer test and reaction time in response to visual and auditory stimuli. The experimental group ingested one capsule containing 1000 mu g octacosanol, a natural substance present in very small amounts in many vegetable oils and waxes, in the leaves of lucerne and wheat, in wheat germ and in other foods, and which is being marketed as a sports supplement, daily for 8 weeks while the placebo group ingested a similar sugarless gelatin capsule. The groups were tested again after 8 weeks and the results were compared using analysis of variance. No significant changes were found in chest strength, auditory reaction time or endurance as measured by the cycle ergometer test. Grip strength and reaction time to a visual stimuli improved consistently and significantly at, or greater than the minimum level of significance. The results suggest that octacosanol can be used as an ergogenic aid to improve some indices of strength and reaction time.
