1.Development of Dietary Schedule for Improved Nutritional Support during Training Period of Junior & Senior High School Fencers in Ulsan City.
Journal of the Korean Dietetic Association 2011;17(1):32-46
This study was conducted in order to improve nutritional support based on analysis of the eating habits and training schedule of junior and senior high school fencers. A survey was conducted on 30 fencers (junior boys=9, girls=7; senior boys=4, girls=10) using a questionnaire. Total daily calorie intakes were 2325.7+/-1168.5 kcal (boy), 2344.0+/-786.3 kcal (girl) for junior fencers and 2183.3+/-726.6 kcal (boys), 2654.4+/-1043.6 kcal (girls) for senior fencers. Nutrients below the RDIs were riboflavin and vitamin C for junior boy fencers and vitamin A, riboflavin, niacin, and vitamin C for senior boy fencers. The rates of the participants who had obtained nutritional information were 44.4% (boys) and 14.3% (girls) for junior fencers and 50.0% (boys) and 80.0% (girls) for senior fencers. Approximately half of the fencers had meals twice a day (55.6% for junior boy fencers, 57.1% for junior girl fencers, and 50.0% for senior fencers). The number of the fencers who were interested in nutrition varied: 66.7% and 28.6% of the junior boy and girl fencers answered they were interested in nutrition, while 25% and 60% of the senior boy and girl fencers showed interest in nutrition issues. Recommendations of total calories were 2,874 kcal (boys) and 2,377 kcal (girls) for junior fencers and 3,398 kcal (boys) and 2,375 kcal (girls) for senior fencers respectively. A dietary plan for the fencing players during training periods was designed to improve their health and performance. Athletes can simultaneously refuel and repair their bodies while contributing to their rehydration goals by consuming fluids that are sources of carbohydrates and protein, e.g., flavored milk and liquid meal supplement. Specific sport nutrition education applicable to athletes, especially young athletes, is recommended under professional support. Professionals may then target particular categories of athletes for the development of educational programs aimed at improving growth and athletic performance.

The purpose of this study was to provide a descriptive assessment of the nutritional habits of resistance trained males in relation to protein and carbohydrate intakes in comparison with the recommended values. Thirty-four male bodybuilders (27.0 +/- 2.1years, 173.5 +/- 5.0 cm, 8.3 +/- 0.61% body fat), twenty-four male weight lifters (20.9 +/- 2.1years, 171.8 +/- 6.9 cm, 7.6 +/- 0.98% body fat) and twenty-five male non-athletes (26.9 +/- 2.5years, 175.3 +/- 5.7 cm,, 8.5 +/- 0.95% body fat) participated in the study. Participants completed a comprehensive survey by twenty-four hour dietary recall methods. All diets were analyzed using the Computer Aided Nutritional (Pro) analyzer by a registered dietician. Body fat was measured using skin fold thickness. The average time spent in resistance training was 18.0 +/- 1.7 hrs/week for body builders and 14.6 +/- 8.7 hrs/week for weight lifters. Total daily calories were 2583.6 +/- 874.8 kcal (31.9 +/- 11.9 kcal/ kg) for bodybuilders, 3565.9 +/- 1281.8 kcal (42.7 +/- 15.0 kcal/kg) for weight lifters and 2016.0 +/- 955.3 kcal (28.1 +/- 13.9 kcal/kg) for non-athletes (p = 0.001). Percent of calories from carbohydrate, protein, and fat 64.2%, 27.1%, and 8.7% for bodybuilders, and 66.3%, 18.6%, and 15.1% for weight lifters. The mean protein intake was 1.9 +/- 1.2 g/ kg of BW for bodybuilders, 1.6 +/- 0.6 g/kg of BW for male weight lifters and 1.1 +/- 0.69 g/kg of BW for non-athletes. Although dietary calcium (78.7%) and riboflavin (86.3%) intakes for bodybuilders were below the RDA, dietary intakes of micronutrients were not deficient. More research needs to be conducted to determine the optimal amounts of protein, carbohydrates, fats, and micronutrients for the resistance trained athletes.

3.Practices of Nutritional Ergogenic Aids Usage by Elite Bodybuilders and Weight Lifters.
Korean Journal of Community Nutrition 2008;13(1):134-142
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.
