Fitness of clothes becomes a major concern in apparel industry. But male sports athletes had difficulties to buy ready-made clothes of good fit. Because ready-made clothes manufactured in companies are produced accordingly to the general person's body types. To solve this problem, it is necessary to classify athletes' upper body into several kinds of somatotypes. The purpose of this study was to classify upper body types of male sports athletes based on the analysis of their upper body types and to provide fundamental data on the development of ready-to-wear clothing appropriate for the upper body types. The subjects for anthropometric measurement were 189 male sports athletes of 20 to 29 year-old. The result of factor analysis indicated that 6 factors were extracted from anthropometric measurements through analysis and those factors comprise 73.807% of total variance. 3 clusters were categorized using 6 factor scores by cluster analysis. Type 1 was taller than other types, had average size in circumference, width and thickness and was bending somatotype. Type 2 exhibits a large circumference in the upper body and straight somatotype. Type 3 was characterized by short, exhibits a large circumference in waist, abdomen and hip and swayback somatotype.

Purpose: A new form of sports human rights platform is needed for policy-related officials, athletes, leaders, and parents to easily share information on sports human rights and to promote communication between the sports community and the outside. Research design, data, and methodology: Participants were collected from athletes (n=3,007) who were registered in Korean Sport & Olympic Committee. Participants were asked to respond the survey items measuring their experiences of human right violations in sport. Descriptive analysis, t-test, and ANOVA were used to analyze data. Results: The platform should include information on prevention and safety of human rights violations during sports activities, procedures and methods for reporting damage, countermeasures, leader education programs, human rights protection guidelines, roles and supervision of sports organizations and institutions, and related statues. It can form a community as well as exchange information in the Internet space through the operation of bulletin boards by professional athletes, student athletes, parents, and leaders, and plays a role in crisis counseling or information provision. Given the reality that players can be blocked from the outside world, information communication channels on SNS can be a useful means of protecting and improving players' human rights. Conclusions: Therefore, it is necessary to provide a foundation for creating related platforms so that sports human rights sites or SNS can be operated voluntarily. Implications and future directions were discussed.

To study the influence of leadership types on achievement goal orientation of high school athletes, Multifactor Leadership Questionnaire (MLQ) and Task and Ego Orientation in Sport Questionnaire (TEOSQ) were used to two-hundred-ninety athletes in Physical Education High Schools. The data from the survey were analyzed by SPSS 19.0 and the results of the analysis were as in the following. First, there were meaningful differences in the leadership factors according to the demographic characteristics. Male athletes tended to be more conscious of the individualized consideration(transformation leadership), contingent reward, management by exception(transactional leadership) of the leadership factors. Second, there were differences in athletes' achievement goal orientation. Comparing to the female athletes, male athletes gave more importance on the task goal orientation. Third, there were differences in the leader's leadership types on the athlete's achievement goal orientation. The athletes with self goal orientation and the individualized consideration (transformational leadership) of leadership types showed statistically meaningful differences. The athletes with high self goal orientation had a negative relationship to the individualized consideration and a positive relationship to the intellectual stimulation. The athletes with task goal orientation showed differences in the transactional leadership as well as in the contingent reward.

The purpose of this study was to examine the impact of the Sport Talent Development Environment on the Achievement Goal in Sport of college athletes. The Sport Talent Development Environment (Martindale et al., 2010) had seven factors, but only four factors (long-term development, lack of quality preparation, communication, lack of understanding) were used after exploratory factor analysis. The Achievement Goals in Sport (Wang et al., 2007) was composed of four factors (mastery approach, mastery avoidance, performance mastery, performance avoidance). The results showed that 1)long-term development factor and communication factor of male athletes were significantly higher than female athletes while lack of understanding factor of female athletes were significantly higher than male athletes, 2)mastery avoidance factor of female athletes was significantly higher than male athletes, and 3)factors of development environment accounted for 27.8% to 34.5%-male athletes and for 13.2% to 22.7%-female athletes variance in the four achievement goals. Therefore, it is important for coaches and sport administrators to take these results into consideration when designing an effective talent development program.

Objectives: Young athletes require adequate nutrition to maintain their athletic performance, growth and health. This study examined the status and needs of nutrition management and meal services for student athletes among the athlete's parents. Methods: The subjects were parents of elementary, middle, and high school athletes (n=323) from 18 schools participating mainly in the Sports Food Truck. The questionnaire included general characteristics, status and needs on nutrition management and meal service for student athletes, and satisfaction with the Food Truck. The survey was done during 2018. The data were analyzed according to the school groups using a ${\chi}^2-test$ or ANOVA. Results: Approximately 45% of subjects had difficulty in the nutrition management of athletes, and 87.1% had not received nutrition education. Approximately 74% wanted nutrition education held for athletes, and mainly wanted topics on nutrition management for health and eating for athletic performance. The preferred methods were lectures and cooking activity. The responses on the necessity of nutrition education for athletes, desired education topics, and desired times for education differed significantly according to the school groups (p<0.05). Most subjects also wanted nutrition information mainly through SNS. In the athlete's meal, breakfast and snacks were highlighted as the meal to supplement. Approximately 90.3% responded that providing a meal service is necessary. The subjects preferred snacks before/after exercise and dinner if a meal service was provided. They preferred Korean food, followed by snacks, and a dish meal. As the meal type, the subjects wanted the Food Truck and packed meal. The responses on necessity of a meal service (p<0.05), preferred food (p<0.001), and meal type (p<0.001) in the meal service differed significantly according to the school groups. Approximately 43% were satisfied with the Food Truck and 50.8% responded as average. They made suggestions for the Food Truck in terms of foods, operations and frequency. Conclusions: Based on the study results, nutrition education and meal service may support nutrition for student athletes considering the needs of the parents according to the school groups.

Management of nutrient intakes through behavior-mordification can be important for improving exercise performance in athletes. The purpose of this study was to determine the effectiveness of nutritional counseling for improving exercise performance capability in athletes. The subjects were seven golfers and fourteen ju-do athletes from Hoseo university, and they have nor received professional hel[ from dieticians. Prior to nutritional counseling, their dietary intakes, lifestyles and dietary habits were evaluated. Nutritional counseling sessions were conducted by a trained dietician every 2-3 weeks for 3-4 month. After 5 counseling sessions, nutrient intakes, lifestyle and dietary habits were re-evaluated. Exercise performance capability was measured by maximal exercise stress test using treadmills. Individual data were assessed as quality index represents the better nutritional status. The common dietary and lifestyle problems were overeating binging, overeating, snacking and drinking alcohol prior to the nutritional counseling. After counseling sessions, the quality index of dietary habits seemed to decrease, especially in ju-do athletes, representing nutritional problems were resolved. Body fat and body mass index decreased in ju-do athletes, but not in golfers. Both athletes have shown to increase oxygen uptake at anaerobic threshold and maximal oxygen uptake status, which represents that the athletic performance capacity was improved after counseling sessions. Their respiratory quotients were decreased. In conclusion, nutritional counseling sessions over five times are an effective and efficient approach to change dietary habits to improve exercise performance capacity. Furthermore, clients can have good dietary habits and learn how to manago muscle strength by behavior modification through multiple nutritional counseling sessions.

The purpose of this study was to analyze, in real time, the glide motion and release motion of domestic athletes and gold and bronze medalists employing the glide technique for the men's shot put at the Daegu World Athletic Championship in 2011. In the glide motion, the Korean athletes had a relatively high body center and shot put heights and lager stretching angles for their hips and knees. In the delivery phase, which shifts to the release phase, the Korean athletes showed slower vertical body center and shot put speeds, and they changed the phase, to the release phase by using a small body angle. In the release phase, the Korean athletes showed differences in their projection speeds and vertical body center speeds. The world-famous players showed high angle speeds, which refer to the composition of the rotation force at the moment of release (body, hip, and shoulder line). In the release phase, the Korean athletes did not have fully stretched hip and knee angles, which might have negatively influenced the vertical speed. Because the Korean athletes showed relatively low projection heights and projection angles. it was found that they need to enhance the muscular power of their, throwing arms and lower limbs.
