The results of the meta-analysis conducted in this field showed that estimates point of taking Ergogenic Substances based on random model in male athletes was 63.9 and was variable between 50.6 to 75.3 percent. Also, the prevalence of taking Ergogenic Substances in female athletes Based on the random model was 28.3 and was variable between 25.3 to 31.4 percent.
