The objective of the present study was to determine the prevalence and type of nutritional ergogenic aids use, and to
determine the frequency, reasons for use of nutritional ergogenic aids. Thirty-four male bodybuilders (mean age = 27.0
years), twenty-four male weight lifters (mean age = 20.9 years) participated in the study. Participants completed a
comprehensive survey detailing their usage patterns. In this study, 78.1% of bodybuilders and 79.2% of weight lifters
reported using nutritional ergogenic aids. The most frequently taken nutritional ergogenic aids, in ranking order, were
protein/amino acid powders (79.4%), multivitamin/minerals (67.7%) and creatine (67.6%) for bodybuilders, in contrast
to sports drinks (100.0%), protein/amino acid powders (50.5%) and creatine (50.5%) for weight lifters. Over the half
of the respondents, 79.4% of bodybuilders and 50.6% of weight lifters, used protein/amino acid powders to gain muscle
mass and to stay healthy. Bodybuilders, 67.6% and weight lifters, 41.7%, used multivitamin/minerals to stay healthy
and for energy. The intakes of most vitamin and minerals through diet and nutritional ergogenic aids were much greater
than RDA. Vitamin B1, vitamin B2, niacin, vitamin B6 and folate intakes were ranged at 400-900%. Vitamin C intake
was 1285.4% (for bodybuilders) and 1322.6% (for weight lifters). The correct answer rate of nutritional ergogenic aids
was 46.0% for bodybuilders and 52.0% for weight lifters. Both bodybuilders and weight lifters took highly nutritional
ergogenic aids and it tended to be taken irrespective of scientific background. Specific sport nutrition education
applicable to athletes, especially strength athletes, is recommended. The findings of this investigation could be used to
enable the professionals (sports dietician and physician) to identify common misconceptions regarding nutritional
ergogenic aids and to implement educational programs. (Korean J Community Nutrition 13(1) : 134~142, 2008)
