Purpose This study aimed to evaluate the nutrient intakes and diet quality of national youth badminton players participating in summer camp training in 2016. Methods Total of 40 middle school players and 60 high school players were included in the study. Two players with skipped meals were excluded from the final target. Food intake data for the 3-day using 24-hour recall method were obtained and analyzed using the CAN-pro 5.0 (Web ver. Korean Nutrition Society, Korea). Differences in nutrient intakes and diet quality were compared between middle school players and high school players using independent samples t-test. Results Intakes of vitamin C, vitamin E, vitamin B6, folic acid, calcium, chloride, magnesium, and zinc in both groups were lower than (RNI) recommended intakes of KDRIs. On the other hand, intake of sodium significantly exceeded the recommended nutrient intake (RNI) of KDRIs in both groups. The NARs (Nutrient Adequacy Ratio) of vitamin C, vitamin B6, folate, calcium and zinc were less than 0.75 in both groups. The NARs of 11 nutrients except for folic acid were significantly lower in high school players. The MAR (Mean Adequacy Ratio) of middle school players was 0.78, significantly higher than 0.64 of high school players. The INQs (Index of Nutritional Quality) of vitamin C, vitamin B6, folic acid, calcium and zinc were less than 0.75 in both groups. The INQs of vitamin A, vitamin B6 and zinc were significantly lower in high school players. On the other hand, the total DDS (Dietary Diversity Score) of high school players was 3.88, significantly higher than 3.29 of middle school players. The DDS of fruit group as well as milk and dairy group were particularly low. Conclusions The results suggest that balanced diet managed by professional dieticians along with nutrition education should be implemented to improve nutrients intake and diet quality of national youth badminton players.
Purpose This study was to investigate the effect of various motor leaning techniques which were applied on the youth soccer training program. Methods 12 elementary soccer players and the director of R youth soccer team have participated in the study. The expertise level of youth soccer team were ranged from beginner to advance. To investigate the effect of new soccer training program we adopted a methodology of action research. We first analyzed the problems of original youth soccer program and reconstructed the training program considering of individualized characteristics. The 3 main problems of original soccer program (1. feedback provisions 2. difficulty of task level 3. time distribution of training) have been reconstructed by four motor learning experts. For the data analysis, several qualitative analyze techniques were conducted to observe player’s improvements. Results First, participants had a better understanding on proper motion of shooting and lifting skills from the guidance techniques. Second, utilizing the personal skills and team cohesion have been improved by the modified rules and space competition. Third, the ability of active problem solving have been improved from the self-learning environment. Forth, the player’s confidence level have been improved by eliminating performance outcome. Conclusions From the aspects of variety circumstances in sport education field, the comprehensive motor learning program should be developed and applied.
PURPOSE This study aimed to investigate the effects of COVID-19 on elite youth athletes by investigating their activities and eating habits before and after the COVID-19 pandemic. METHODS This study included 917 elite adult athletes from 19 sports and were grouped into 6. The questionnaire included items regarding demographics, physical activity, sleep, and eating habits before and after COVID-19. A total of 44 questions requiring subjective short answers were included. Statistical significance was set at p< 0.05. RESULTS After COVID-19, vigorous and moderate activity decreased across all sports; however, light activity increased in almost sports. Time spent sitting increased across all sports. The difference in the number of meals consumed varied among sports, and the number of competitions decreased in all sports. CONCLUSIONS The COVID-19 pandemic appears to be finished but has not ended yet. Athletes must determine the best way to maintain their physical, physiological, and psychological states close to their original abilities. Determining this will provide the greatest impact on the return of athletes after COVID-19; this study will be helpful.
PURPOSE The purpose of this study was to compare the dynamic postural control of youth athletes with and without a history of lateral ankle sprains. METHODS Twenty-eight youth athletes (14 lateral ankle sprain, 14 healthy control) participated in this study. All participants answered the Foot and Ankle Ability Measure questionnaire and were subject to the Star Excursion Balance Test (SEBT) for dynamic postural control evaluation to collect the joint angles of the lower extremity, a center of pressure (COP) path, and COP velocity. Independent sample t-test or Mann-Whitney U-test were performed to analyze the difference between the groups. RESULTS The lateral ankle sprain group (LAS) was found to have a long experience in participating in sports, and low Foot and Ankle Ability Measure scores were identified when compared to the healthy control (CON; p<0.05). LAS was observed with a short reach distance, less hip flexion, and dorsiflexion angles during the anterior direction of SEBT when compared to CON (p<0.05). Furthermore, LAS showed a slower anteroposterior and mediolateral center of pressure velocities in the posteromedial aspect of SEBT and a slower anteroposterior COP velocity in the posterolateral aspect of SEBT when compared to that of CON (p<0.05). There were no differences between the groups with respect to the other variables (p>0.05). CONCLUSIONS Based on these results, decreased anterior reach distance of SEBT may be affected by changing the dynamic posture control strategy of the lower extremity joint on the sagittal plane in LAS.
Purpose The purpose of this study was to develop a Korean Life Skills Scale for Sports (KLSSS) that original version is the LSSS developed by Cronin and Allen (2017). Methods The subjects were 899 middle school and high school students. The measurement tool was used with LSSS. The validation of KLSSS followed a three-stage of validation procedure; substantive stage, structural stage, and external stage. The result is as follows. Results First, In the substantive stage, KLSSS consisted of 47 items with 8 factors. As a result of the item clarity test, it was confirmed that all the items were appropriate. Second, in the structural stage, KLSSS was explored and confirmed as 5 factors and 18 items. Third, in the external stage, KLSSS showed discrimination and convergent validity. Conclusions KLSSS is composed of 5 factors and 18 items. The factors are teamwork (TW), goal setting (GS), time management (TM), social skills (SS), and leadership (LD). This scale can be used to obtain information on life skills in school physical education or sports.
PURPOSE The purpose of this study was to validate the Korean version of Coaching Life Skills in Sport Questionnaire (KCLSS-Q). METHODS Substantive, structural, and external stages were undertaken to address the purpose of this study. At the substantive stage, the scale was translated by discussing with an expert panel and testing item clarity. Ten coaches (9 males, Mage=33.80, SD=4.21) participated in the item clarity test. At the structural stage, descriptive statistics, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were conducted. A total of 249 (214 male, Mage=34.18, SD=6.82) and 232 coaches (186 male, Mage=34.26, SD=7.69) participated in the EFA and CFA, respectively. At the external stage, correlation analysis using other scales (emotional intelligence in sport coaching, EISSC) was conducted to examine concurrent validation. A total of 130 copies of the CFA data were randomly extracted and used for this stage. RESULTS For the EFA, the scale extracted five factors with 27 items. In the CFA, however, five factors with 26 items were identified as an appropriate structure. Finally, the relationships of all sub-factors between KCLSS-Q and EISSC were statistically significant in the correlation analysis. CONCLUSIONS KCLSS-Q should reasonably consists of nine items on structuring and facilitating a positive sport climate, five on understanding life skills, four on practicing life skills, five on understanding life skills transfer, and three on practicing life skills transfer. KCLSS-Q can be used as a valid measure to evaluate the coaching life skills of Korean coaches.
PURPOSE This study aims to analyze research trends on the social capital in sports. METHODS A total of 69 papers published until December 2020 were selected as research subjects. Further, Excel, KrKwic software, and NetDraw function of the UCINET 6 program were used for analysis. RESULTS First, social capital research on sports has shown quantitative growth since 2010. Second, the studies were conducted on sports participants such as general, elderly, college students, adolescents, foreigners, and the disabled, showing the highest frequency of research subjects. Third, quantitative research conducted based on the research method were several. Fourth, single-author studies were the highest. Fifth, as the result of the analysis on the publication journal, the Journal of the Korean Physical Education Association was shown the highest. Sixth, due to frequency analysis of the thesis keywords, “social capital,” “sports participation,” “action intention,” “social capital type,” “living sports participation,” and “youth” were shown the highest. Seventh, as a result of centrality analysis between keywords through the network analysis, “sports participation” in connection centrality, “health-promoting lifestyle” in proximity centrality, and “sports participation” in mediation centrality were found as the highest. CONCLUSIONS The significance of social capital in sports is more important than others because it is a fundamental element for creating a culture where more people can enjoy sports moderately in Korea, where capitalism and liberal democracy were adopted as the governing system. Therefore, this study can be a vital resource significantly contributing to the understanding and active use of social capital, a significant factor in developing sports in Korea.
PURPOSE This study aimed to apply a capacity building program to sport life skill leaders and to provide cases of this process. METHODS The study participants included four leaders (male=2, female= 2, Mage=37.5) who were managing a sport life skills program at a university. They participated in a capacity building program, which consisted of (a) understanding (leader seminar), (b) application (managing the sport life skills program), and (c) evaluation (leader’s self-reflection), which were conducted in eight sessions. Four leaders conducted self-evaluations using program quality assessment (PQA) during every session, and quantitative and qualitative data were collected. Qualitative data were derived using a cross-case analysis, and quantitative data were used for calculating the effect size after performing the paired t-test. RESULTS Analyzing the reported cases of sport life skill leaders, the use value of the capacity building program was identified. Furthermore, the cases reported by the four leaders enabled observation of how the leader’s capabilities were strengthened. In the paired t-test, the effect size of physical and psychological safety, appropriate structure, supportive relationship, opportunities to belong, support for efficacy mattering, opportunities for life skill building, excluding integration of family, school, and community effort, were all significant. All effect sizes were found to have “very large effects.” CONCLUSIONS The capacity building program played a positive role in strengthening the leaders’ life skill coaching capabilities. These findings have practical implications—chiefly, it is important to strengthen leaders’ or coaches’ capabilities in order to foster life skill development and transfer of student-athletes.
Drawing on Bernstein theory (1990, 1996) of pedagogic discourse, this study is aimed at exploring the construction of pedagogical meaning in physical education policy in Korea and providing critical implications for the development of policies for physical education and school sport. Both open-ended questionnaires (n=22) and in-depth interviews (n=9) were conducted. The collected data was commissioned by an inductive data analysis to look at patterns of regulative discourses embedded with physical education policy influencing on teachers’ educational practice. This study identified three main discourses constructing and constituting policies; sport, moral, and health. Sport discourse was the most dominant through the policy, in which two sub-discourses were central: ‘competition’ and ‘exclusion.’ Moral discourse had a strong connection with ‘crime reduction’ and ‘academic achievement.’ The structure of health discourse alleged increase in youth physical inactivity associated with sedentary living leads to an obesity epidemic. This study argued that there were significant dangers which dominant regulative discourses created a limited universe of possibilities for physical education. Therefore, we must not lose sight of the powerful discourses produced in the primary field, which have an impact on shaping forms of policy and practice in physical education. Furthermore, we need to examine in detail forms of physical education practice in order to achieve alignment in the school practice with current dominant discourses.
