This study was performed to compare nutritional supplementation habits for Korean professional soccer players with those for the non-athletic male adults. Information about prevalence and kinds of supplements taken, information sources, nutrition knowledge were collected. Data were obtained from 53 football players working for Korean professional football clubs and 44 non-athletic males, who answered a list of questionnaires which had been prepared in advance. The prevalence of supplement use in the soccer player group (96%) was strikingly higher than in the nonathletic male group (34%). Vitamins were taken most frequently, followed by red ginseng, multivitamin, Chinese medicine and amino acids supplements in the soccer player group, with each player taking 2.96 kinds of supplements in average. Multivitamin was the most popular supplement in the non-athletic male group. The major reason for taking supplements was not to feel and recover from fatigue in both groups. It appeared that the non-athletic males started to use supplements mostly by recommendation of friends or colleagues. Meanwhile, soccer players took supplements on their needs, with half of them (50.1%) provided with nutrition information. The most important information source was coaches for soccer players group, and mass media for the non-athletic male group. The average scores of soccer players group on basic nutrition and athletic nutrition were lower than the respective values of the non-athletic males. Among the soccer players, 68% had taken more than 3 kinds of supplements during the last year; nonetheless, more than half could not perceive the effectiveness of the supplements. Our results show that supplementation practices were widespread in soccer players, and suggest that nutrition education for proper use of supplements and overall health care is needed for soccer players.

In view of the importance of muscle-specific creatine kinase (CKMM) gene as a genetic factor for athletic performance, we investigate the relationship between elite athletic performance and two restriction fragment length polymorphisms (Ncol and Taql RFLPs) in the CKMM gene. Genomic DNA was extracted from white blood cells of 98 unrelated male Korean elite athletes and 04 sedentary controls, respectively. Two genetic polymorphisms in the CKMM gene were detected by the polymerase chain reaction and the digestion with restriction endonucleases, Ncol and Taql, respectively. There were no significant associations between two genetic polymorphisms in the CKMM gene and elite athletic performance or clinical parameters in our subjects. Therefore, these findings suggest that two genetic polymorphisms in the CKMM gene may not be useful as genetic markers to predict the athletic performance in male Koreans.

The aim of this study was to investigate influence of body build on body composition, energy metabolic state and insulin concentration of blood. 29 male athletes and 36 male non-athletic students were recruited for the study. Anthropometry including chest depth and breadth, fat mass, fat fee mass, tricep skinfold thickness were measured. fasting glucose, lactate, triglyceride, fee fatty acid, and insulin concentration in serum were measured . Body build was assessed using metric index, which calculated by regression equations of Mohr and Greil. The athletic and non-athletic students were allocated to 3 body build, that is leptomorph, mesomorph, and pyknomorph. Resting metabolic rate was calculated. Respiratory quotient was determined through ratio of measured VO$_2$, and V$CO_2$. Most non-athletes have a leptomorphic body build, in contrast to athletes mesomorphic type. The body build type influenced body composition differently between non-athletic group and athletic group. Weight, body mass index, body fat mass and fat mass proportion (%), and fat-free mass increased from leptomorph to pyknormorph in non-athletic group. Pyknormorphic athletes have a significant higher body mass index, fat mass, fat free mass than other body build type. Serum glucose, triglyceride, lactate, insulin showed significant differences only in non-athletic group between leptomorph and mesomorph. RMR increased significantly from leptomorph to mesomorph in non-athletes. There was no significant difference of RQ among 3 body build types in both athletes and non-athletes. This study gives a coherent data on body build and body composition for athletes and non-athletes students. The influence of body builds on energy metabolic status of serum was different between athletes and non-athletes.

This study compared activity factor. predicted resting metabolic rate (RMR), and nutrient intakes between athletic and non-athletic high school students in Gangwon-do. Fifty soccer players (30 males and 20 females; mean ages 16.7${\pm}$1.0 years and 16.4${\pm}$1.1 years. respectively) and 50 non-athletic (30 males and 20 females: mean ages 17.5${\pm}$0.4 years and 16.4${\pm}$1.1 years respectively) high school students were included. Anthropometric measurements included: weight and height. triceps skinfold, mid-ann circumference, and body fat. Prediction equations consisted of those from the Harris-Benedict. FAO/WHO/VNU, IMNA, Cunningham, Mifflin et al., and Owen et al. A one-day activity diary was collected by interview, and the 24-hour recall method was used to analyze nutrient intakes of subjects. The activity factors of the male and female athletic groups (2.23 and 2.16, respectively) were significantly higher than those (1.52 and 1.46, respectively) of the non-athletic group. There was only a significant difference in RMR by use of the Cunningham's equation between two groups. For the males. almost all nutrient intakes of the athletic group (except carbohydrate, iron, vitamin $B_1$, $B_6$, and niacin) of athletic group were significantly higher than those of the non-athletic group. The female athletic group showed significantly higher nutrient intakes with the exception of most vitamins. These results suggest that assessments of energy balance between energy intake and energy expenditure by employing RMR and activity factors would be useful to prevent and treat obesity in high school athletes. In addition, the Cunningham's equation would be appropriate for predicting their energy needs.

In the previous studies, some genetic polymorphisms in the human mitochondrial DNA have been associated with athletic performance in several populations. To investigate the relationship between mitochondrial DNA 5178A/C polymorphism and athletic performance in Korean population, blood samples were collected from 100 male Korean elite athletes and 64 sedentary controls. There was no significant difference in allele frequency of mitochondrial DNA 5178A/C polymorphism between two groups (P > 0.05). However, 5178A allele frequency in Korean population was very higher than those in other populations studied. Because it has been reported that this genetic polymorphisms is associated with longevity, further study will be needed to clarify the relationship between this genetic polymorphism and life expectancy of Korean population.

BACKGROUND/OBJECTIVES: Athletes generally desire changes in body composition in order to enhance their athletic performance. Often, athletes will practice chronic energy restrictions to attain body composition changes, altering their energy needs. Prediction of resting metabolic rates (RMR) is important in helping to determine an athlete's energy expenditure. This study compared measured RMR of athletic and non-athletic adolescents with predicted RMR from commonly used prediction equations to identify the most accurate equation applicable for adolescent athletes. SUBJECTS/METHODS: A total of 50 athletes (mean age of $16.6{\pm}1.0years$, 30 males and 20 females) and 50 non-athletes (mean age of $16.5{\pm}0.5years$, 30 males and 20 females) were enrolled in the study. The RMR of subjects was measured using indirect calorimetry. The accuracy of 11 RMR prediction equations was evaluated for bias, Pearson's correlation coefficient, and Bland-Altman analysis. RESULTS: Until more accurate prediction equations are developed, our findings recommend using the formulas by Cunningham (-29.8 kcal/day, limits of agreement -318.7 and +259.1 kcal/day) and Park (-0.842 kcal/day, limits of agreement -198.9 and +196.9 kcal/day) for prediction of RMR when studying male adolescent athletes. Among the new prediction formulas reviewed, the formula included in the fat-free mass as a variable [$RMR=730.4+15{\times}fat-free\;mass$] is paramount when examining athletes. CONCLUSIONS: The RMR prediction equation developed in this study is better in assessing the resting metabolic rate of Korean athletic adolescents.

This research was to examine the correlation between body composition and life style including nutrients intake and physical activities of male and female athletes and nonathletes who are attending college. The percent of body fat with a skinfold caliper was measured higher in female than male. The body fat of the female students in the nonathletic group was the highest and male students in the nonathletic group showed the lowest in body fat. On the correlation between skinfold thickness and body composition the skinfold thick-ness showed negative correlation with the body density. However it showed positive correla-tion with the percent of body fat. According to this result it can be defined that skinfold thickness is in proportion to the body fat. dietary intakes of male and female athletes exceeded the need for their excessive physical activity. Concerning the correlation between calorie intake and body fat was high. From this we conclude that the more one consumes calorie intake the higher one's body fat content will be. On the correlation of physical activity and body composition the lean body mass showed high positive correlation with physical activity.
