The objective of this study was to analyze the concurrent treatment effects of ursolic acid (UA) and low-intensity treadmill exercise and to confirm the effectiveness of UA as an exercise mimetic to safely improve muscle atrophy-related diseases using Sprague-Dawley (SD) rats with skeletal muscle atrophy. Significant muscle atrophy was induced in male SD rats through hind limb immobilization using casting for 10 days. The muscle atrophy-induced SD rats were group into four: SED, sedentary; UA, daily intraperitoneal UA injection, 5 mg/kg; EX, low-intensity (10-12 m/min, $0^{\circ}$ grade) treadmill exercise; and UEX, daily intraperitoneal UA injection, 5 mg/kg, and low-intensity (10-12 m/min, $0^{\circ}$ grade) treadmill exercise. After 8 weeks of treatment, endurance capacity was analyzed using a treadmill, and tissues were extracted for analysis of visceral fat mass, body weight, muscle mass, expression of muscle atrophy- and hypertrophy-related genes, and endurance capacity. Although the effects of body weight gain control, muscle mass increase, and endurance capacity improvement were inadequate in the UA group, significant results were confirmed in the UEX group. The UEX group had significantly reduced body weight and visceral fat, significantly improved mass of tibialis anterior and gastrocnemius muscles, and significantly decreased atrophy-related gene expression of MuRF1 and atrogin-1, but did not have significant change in hypertrophy-related gene expression of Akt and mTOR. The endurance capacity was significantly improved in the EX and UEX groups. These data suggest that concurrent treatment with low-intensity exercise and UA is effective for atrophy-related physical dysfunctions.
This study aims to develop a life-friendly, wrap-one-piece style dance sports practice wear considering the physical characteristics of middle-aged, abdominally obese women. These types of practice wear allow people to enjoy exercise easily and to wear these garments as daily wear while meeting the requirements for dance sports wear. The three participants selected for this study were all women with five or more years of dance sports experience and were all average sized on Korea's abdominal obesity scale. In the first phase of the study, practice wear was created in a total of nine styles with three different styles of neckline depths for three different styles of dress skirt lengths. In the second phase of the study, the practice wear was created in 15 styles with five different styles of sleeve lengths for three different styles of waistline heights. After analyzing the design preferences of the participants, the fit preferences of the designs were evaluated and the final appearance was analyzed in order to suggest a pattern. The results of the subjects' first and second preference evaluations showed a preference for a 10 centimeter neckline depth, for high waistlines, and for elbow to wrist-length sleeves. The implementation of this research is expected to be extensive, as its results can be used as basic data for making lifestyle dance sports practice wear that covers the physical insecurities of middle-aged, abdominally obese women and enables them to enjoy their leisure time.
The purpose of this study is to identify the characteristic of the length of sentence of sports news articles compared with other sections, other newspaper and sports events. In order to achieve this purpose, 4 daily newspapers(Chosun Ilbo, Dong-A Ilbo, Kyunghyang Shinmun and MKsports) were selected as research sources. The length of sentence of collected articles was analyzed by One way ANOVA and Scheffe as post-hoc. The results of these analyses are summarized into three as follows: First, the length of sentence of news articles has significant difference by sections. To put it concretely, the sentences in politics section were the longest, and then economy, editorials comes. The sports section has the shortest sentences. Second, the length of sports articles has significant difference by newspapers. In particular, MK sports which is a sports-oriented newspaper has the shortest in the length of sentence of sports articles than other newspapers such as Chosun, Dong-A and Kyunghyang. Third, the length of sentence of sports articles has significant differences by the sports events. More specifically golf is the longest, and then basketball, soccer and baseball follows.

Park golf is establishing itself as a daily sport that the silver generation can enjoy physically and cost-free. Accordingly, we have examined the impact of park golf participants' passionate participation behavior on sports immersion and sports performance. The subjects were 243 park golf participants, and SPSS 21.0 and AMOS 18.0 were used for data processing. In addition, frequency analysis, reliability, confirmatory factor analysis, and correlation analysis were conducted. Path analysis was performed using SEM, and mediating effects were analyzed using bootstrapping. First, regarding the relationship between passionate behavior and sports immersion, harmonious passion did not affect sports immersion, and obsessive passion had a positive effect. Second, passion had a positive effect on sports performance. Third, sports immersion had a positive effect on sports performance. Fourth, sports commitment played a partial mediating role in the relationship between passion and sports performance. Therefore, if the environment of the park golf course is improved so that passion does not decrease, exercise immersion and exercise performance will improve.
The purpose of this study is to comprehend the contemporary sports star fashion and to contemplate aesthetic characteristics of sports star fashion, thereby to establish the styles of sports star fashion. For such purposes, this study first examines aesthetic characteristics of sports fashion and star fashion based on previous studies, in order to analyze aesthetic characteristics of sports star fashion, and conducts a case study by analyzing photographic materials of fashion styles of well-known male sports stars such as the English soccer player David Beckham and American golf player Tiger Woods. The result of this study is as follows: the aesthetic characteristics of the contemporary sports star fashion are virility, functionality, sensuality and deconstruction. (1) Virility emphasizes manly features by displaying trained and disciplined body. (2) Functionality is expressed through structural simplicity and temperance of decoration. High-tech textiles and fibers are favored in order to fit in comfortable bodily movement for the heavy exercises. (3) Sensuality, as an expression of indulgence of sexual pleasure, is expressed through bodily exposure. Lastly, (4) deconstruction, which means destroying existed boundaries of cultural categories, is shown as co-existence of design elements from different times and places, stereotypes and sensibilities. Virility and functionality are prominent characteristics expressed in sports uniforms and training costumes. Sensuality and deconstruction are shown in daily fashion and formal dress outside the sports field.
Sportswear transforms itself into a new fashion item to satisfy desires for beauty in addition to having functionality and movability for sports activities. Sportswear is not in fashion just temporarily but comes in various forms along with sociocultural phenomenon that put emphasis on well-being and leisure. This research aims to study the needs of the bikers who ride bicycles or cycles has become a popular outdoor activity, and give suggestions for high functional sports design that can satisfy the needs of the highly demanding taste of athletes. To understand the design development direction and design preference, practical consumer needs were derived through a survey analysis on bike wear purchasing satisfaction and actual wearing state by bike riders. For consumer needs analysis, focus group interview, in-depth interview and questionnaire method were used. Based on analysis of those researches, athleisure bike wears appropriate for urban sports activities were categorized into sports, life, fitness and leisure 4 styles for athleisure bike wear design development. It is believed that this study will contribute to in the category expansion of sports wear market and satisfy the consumer demands for functional and specialized casual bike wears as well as fashion factors optimized to life style of modern people.
As health and well-being become a global trend, the younger generation is focusing on the balance between work and leisure time and they are interested in sports activities as well as a cultural life. In addition, the range of sportswear is expanding, so that athleisure fashion is getting into daily lives. In particular, consumer groups in the sportswear market are beginning to change since generation Z consumers are more and more interested in sportswear and their needs are also growing of health and functional of sports wear. It's a global trend that athleisure fashion market is growing, which combines professional athletic wear with fashion. As the number of women who enjoy sports and leisure in their spare time, the consumer pattern in the sports wear market is also expanding to female customers. However, most sports functional wears were focused on male consumers, so that functional inner-wears are mostly made for both sexes, which mean the functional inner-wears are produced without considering the physical characteristics of men and women and with not enough size division ending up not suitable for professional athletes. In particular, female professional athletes need functional inner-wear that fits the characteristics of the sport because they are not only different in physical condition and they are also using different muscles for different movements. Therefore, functional inner-wear needs pattern development and size system setting considering the body shape and athletic movement of female professional athlete.

This epidemiological study aims to determine the incidence, areas, severity, and time of occurrence of sports injuries in elite female rowing athletes who were training at the Jincheon National Training Center for a 1-year period from January 1st to December 31st, 2017. According to the daily injury reports form of the IOC, sport events, weight division, injured area, and cause of injury were recorded, and the following results were found. Upon comparing the incidence of sports injuries, there was a significant difference in weight of double scull athletes. In terms of sports, there was a significant difference between pair and athletes who played double skull. Injuries occurred most commonly in the lower extremity (40.5%), followed by the trunk (35.1%), upper extremity (24.3%). for all athletes in rowing. The knee and lumbar spine/lower back were the most common injury sites. More than 60% of all injuries were Level III, and injuries occurred most frequently during training, followed by weight training and then competition.
Purpose: This study aimed to investigate changes in upper extremity joints and leisure satisfaction in children with brain lesions through sports stacking activities. Methods: A sports stacking program was conducted on three children with brain lesions who had upper extremity joint limitations and joint range of motion lower than the normal range. It was conducted 10 times, 1 to 2 times a week, 40 minutes each time. Upper extremity joint angles were measured using a goniometer in the order of shoulder, elbow, wrist, and fingers, and leisure satisfaction was measured using a smile evaluation. Results: As a result of measuring the upper extremity joint angles, all three children showed slight angle changes in the shoulder, elbow, and wrist areas. Differences in joint angles appeared differently for each child. Smile evaluation results were evaluated in various psychological, educational, and physical aspects. Only child A was evaluated for Smile Evaluation No. 1. Conclusion: Sports stacking activities changed the upper extremity function of children with brain lesion disorders and showed differences in psychological, physical, and educational aspects of leisure satisfaction. As this is a short-term study result, the change in upper extremity function is minimal, but if sports stacking activities are continued, it will be a rehabilitation program that can prevent upper extremity dysfunction and improve physical strength. Accordingly, continuous attention should be paid to increasing accessibility and enjoyment of daily life according to individual characteristics and level.

PURPOSE: This study examined the incidence, location, and characteristics of sports injuries according to the position in Korean national Kabaddi athletes. METHODS: Twenty-four national Kabaddi athletes (12 males and 12 females) who trained at the national training center between January 2019 and December 2019 were enrolled in this study. The event, position, and location of injury were recorded on an IOC daily injury report form. The incidence of sports injury was examined with the 95% confidence interval (CI), and the difference in the incidence of injury by position was presented as the rate ratio (RR). Moreover, the differences in the location of sports injury according to position were examined using χ2 tests. RESULTS: One hundred and nine sports injuries occurred among Kabaddi players, with an incidence of 20.28 cases of injuries per 1,000 exposures (95% CI 16.47 - 24.08), and the incidence of injury was the highest among the competition, followed by training and weights. The most common location of sports injury was the lower extremity, followed by the upper extremity, trunk, head, and neck. In addition, no significant differences in the locations of the sports injuries were noted according to gender (p = .689). Furthermore, knee, ankle, lumbar spine/lower back, shoulder/clavicle were common sites of sports injury among Kabaddi players. CONCLUSION: These results provide a baseline for predicting sports injuries occurring in athletes during games, and would provide useful information for developing performance enhancement as well as injury prevention programs.
