PURPOSE: This study compared the body composition according to the sport of short-distance and middle & long-distance athletes to identify the factors that affect the body composition. METHODS: Forty-eight athletes selected as youth national athletes in 2019 participated in the study. The study participants measured the length of the lower extremities, body composition, and anaerobic ability. An independent sample t-test was conducted to compare the body composition according to the event. In addition, the Pearson correlation was performed to identify the factors that influence the body composition. RESULTS: The leg length of the Short and Middle & long-distance athletes were similar (p = .584). On the other hand, there were differences in the body fat percentage (p = .001), lean percentage (p = .001), and BMI (p = .001). In addition, the body fat percentage was correlated with the lean body mass (r = .419) and BMI (r = .447). Furthermore, the lean body mass was correlated with the BMI (r = .849) and the peak power (r = .662) and mean power (r = .686) of the anaerobic capacity. Moreover, the BMI was correlated with the peak power (r = .490) and mean power (r = .543) of the anaerobic capacity. The peak power of the anaerobic ability was correlated with the mean power (r = .931). CONCLUSION: The body composition differed according to the sport. The body fat percentage correlated with the lean body mass and the BMI. The lean body mass correlated with the BMI, peak power of anaerobic ability, and mean power. The BMI correlated with the anaerobic capacity.

In an effort to elucidate the physiological characteristics in cardiopulmonary function, electromyogram(EMG), and blood chemistry in athletic high school students, an analysis of electrocardiogram(ECG) and EMG, pulmonary function test, venous blood gas analysis($Pvo_2$ and$Pvco_2$), and measurement of heart rate, blood pressure, respiratory rate, blood glucose and blood lactate were made for 16 to 19 year-old high school students who were divided into athletic (n=19) and non-athletic (n=20) group. The results obtained are summarized as follows. 1) ECG intervals in athletes were longer than in non-athletes, and the difference was significant in R-R, Q-T and T-P intervals. Resting heart rate in athletes was 56.3/min showing a bradycardia compared with 79.8/min in non-athletes. Amplitudes of R and T waves in lead $V_5$ were significantly higher than in non-athletes. 2) Pulmonary function parameters in athletes showed higher values than in non-athletes. Parameters which showed significant differences were FEV 0.5, PEF, FEF 25%, PIF and FEF $200{\sim}1.200\;ml. 3) Heart rate, blood pressure, and respiratory rate after exercise were significantly elevated from resting values. Heart rate and respiratory rate showed greater increase in non-athletes, while blood pressure showed greater increase in athletes. 4) $Pvo_2$ was lowered ana $Pvco_2$ was elevated after exercise, and there was no significant difference between two groups. 5) Blood glucose and lactate levels were elevated after exercise. The difference was significant in blood lactate, and was greater in non-athletes. 6) EMG amplitude was steadily increased with increasing load of exercise, and the increase was greater in athletes than in non-athletes.

This study attempted to investigate the effect of competitive anxiety on injury psychology according to the athletic career of tennis athletes at Chinese universities. To study the method, 208 athletes enrolled in a four-year university (0 university, 0 university) located in A City, Hanam Province, were surveyed for a total of three weeks from the end of January to the beginning of February 2023. To verify the research model, frequency analysis, exploratory factor analysis, reliability analysis, and correlation analysis were conducted using SPSS Statistics 25. And independent sample t-test and one-way ANOVA were conducted to find out the differences in variables according to general characteristics, and multiple regression analysis was conducted to verify hypotheses through the concept of measurement. As a result of the study, first, it was found that there was a significant difference in the athletic career of tennis athletes at West China University. Second, the non-standardized coefficient of competition anxiety was found to have a positive (+) effect on exercise weaponry. Third, the non-standardized coefficient of competition anxiety was found to have a positive (+) effect on anxiety and anxiety. Therefore, it was found that other competitive anxiety in the exercise career had an effect on injury psychology. Since competition anxiety according to the athletic career of tennis athletes at Chinese universities affects injury psychology, it suggests that a psychological program that can control competition anxiety and injury psychology of athletes should be developed and introduced to athletes.

Purpose: This study was designed to analyze? the chronic pain of adolescent Taekwondo athletes, to research the understanding about chronic pain of coaches and athletes, to? reduce the development of chronic pain. Materials and Methods: From March. 2006 to June 2007, 210 athletics and 12 coaches of elementary, middle and high school in Kwang-ju city were surveyed. They was evaluated by physical examination, simple radiographs and MRI. Results: In 210 athletics, 162(77.1%) athletes had chronic pain. 19(11.7%) athletes had over three regions of pain, 74(45.7%) athletes had two regions of pain, 69(42.6%) athletes had one region of pain. In 274 cases of 164 athletes, the most common region was foot and ankle(145 cases, 52.9%), followed by hand(47 cases, 17.2%) and knee(38 cases,13.9%), hip(25 cases, 9.1%), and lumbar area(19 cases, 6.9%) The chronic pain was classified by injury type. Contusion of foot was 103 cases(most common), sprain of ankles was 40cases, Contusion of hands and wrists was 28 cases, and so on. The etiologies of injury that causes the chronic pain were match injury in training that is most common, intensive exercise and match injury in competition. Conclusion: The chronic pain was common in adolescent Taekwondo athletes. The ankle and foot were the most common region of chronic pain and the match injury was the most common injury, caused the chronic pain. Although athletes had considerable mental stress about chronic pain, the treatment of chronic pain and rest were insufficient. Therefore the variable effort to prevent injury and to treatment injury must be considered importantly.

Purpose: Poor living conditions such as overcrowding and sharing a bed are reported to be significant risk factors for H. pylori infection throughout childhood. We investigated the prevalence of Helicobacter pylori infection in Korean athletes who are obliged to live together in training camps over six months a year. Methods: Blood sampling and surveying through questionnaire were performed on 440 regular high school students (228 boys and 212 girls) and 220 athletes (148 boys and 72 girls) of a physical education high school. We measured serum IgG Ab to H. pylori in order to compare the prevalence of H. pylori infection between normal adolescents and athletes. In addition, we conducted a nutritional analysis and questionnaire survey for socioeconomic status in order to compare other risk factors that might influence H. pylori infection between groups. Results: The prevalence (43.2%) of H. pylori infection in athletes was higher than that (22.7%) in the controls. No significant differences in the nutritional factors or socioeconomic status, such as Hollingshead index, type of house, and crowding index, were found between the groups. Multivariate analysis showed that crowding and the difference in school type were the significant predictors of H. pylori seropositivity after controlling for dietary and socioeconomic factors. Conclusion: Living together in training camps might be a significant risk factor for H. pylori infection in athletes.
