PURPOSE This study aimed to analyze physical activity (sedentary, light, moderate to vigorous physical activity [MVPA]) characteristics of middle school students based on region (urban and rural) and sex. METHODS Data were collected from 216 students across 6 middle schools located in medium-sized urban (3 schools) and rural areas (3 schools), and the relevant physical activity was measured using a three-dimensional accelerometer (GT3X model). The collected data were inputted into the SPSS 20.0, and descriptive analysis and two-way ANOVA based on region and gender were performed (<.05). RESULTS The descriptive statistical analysis resulted in the following achievement rate of the physical activity standard (MVPA 60 minutes/day): 9.4%. The two-way ANOVA showed that the main effect according to gender was found in sedentary activity (F=5.258), light activity (F=6.790), and MVPA (F=32.274); furthermore, the main effect according to region was found in light activity (F=10.888) and MVPA (F=7.876). Interaction effect according to region and gender was found at all intensities, and the gap between rural and urban in male students was larger compared to that of female students. CONCLUSIONS After COVID-19, the level of physical activity among adolescents has worsened; this study found the problem of “decrease in physical activity; increase in sedentary activity” to be more serious among male students in urban areas.

PURPOSE This study aimed to identify the dimensions of sport brand authenticity and to develop a valid and reliable scale for measuring such dimensions. METHODS Along with a sequential mixed method design, qualitative researches were conducted (a literature review on brand authenticity and the inherent value of sport, 5 one-to-one expert interviews, and a Delphi survey of 10 researchers). Based on the qualitative research results, an EFA (n=304), 2 times CFA (1st: n=304, 2nd: n=311), and correlation analysis using the other scale (brand relationship quality, brand attachment, brand credibility) were conducted to test reliability, construct validity, and criterion-related validity. RESULTS In the qualitative research results, 8 dimensions with 36 items were extracted; however 6 dimensions (originality, connectedness, legitimacy, authority, sport spirit, and expertise) with 28 items were identified as appropriate structures from EFA and CFA, and the relations between all the dimensions and other scales related to consumer attitude were statistically significant in the correlation analysis. CONCLUSIONS The findings suggest that the scale in this study could provide a new and specific perspective on sport brand authenticity, which is constructed using a general aspect and a sport specific aspect, and an understanding of the concept of sport brand authenticity in other sport industries.

PURPOSE This study aimed to examine the associations between accelerometer-measured physical activity and both cardiometabolic disease risk factors and metabolic syndrome in Korean adults. METHODS We performed a retrospective cohort study with age-sex matched case-control using data from the 2014-2016 Korea National Health and Nutrition Examination Survey, which was administered to South Korean adults (n=320). Individuals were categorized into quartiles based on accelerometer-measured moderate-to-vigorous physical activity (MVPA). Demographic and physical characteristics, waist circumference, visceral adiposity index, blood pressure, lipid profiles, and TG/HDL-C were observed. The associations between MVPA status and cardiometabolic disease risk factors as well as metabolic syndrome were determined using multiple logistic regression. RESULTS For the waist circumference, SBP, DBP, MBP, visceral adiposity, triglyceride, and a surrogate estimate of insulin resistance, the Q1 and Q2 groups had higher means compared with the Q3 and Q4 groups. HDL-C was higher in the Q3 and Q4 groups compared to the Q1 and Q2 groups. Odds ratios for cardiometabolic disease risk factors and metabolic syndrome decreased in a curvilinear manner with the increasing quartile of MVPA. CONCLUSIONS Adults with higher MVPA participation were strongly associated with cardiometabolic disease risk factors and metabolic syndrome.

PURPOSE This study aimed to identify movement pattern differences in the running of youth soccer players with and without lateral ankle sprain (LAS) histories. METHODS A total of 12 participants were recruited and assigned to the LAS group or the control group. All participants were assessed for anthropometric data, and they filled in the subjective ankle function questionnaires. Then, reflective markers were attached to their bodies, and they were instructed to run at the preferred speed on the 9-m runway thrice. 3D joint angles for ankle, knee, and hip joints were exported, and their mean values and 95% confidence intervals were calculated. Ensemble curve analysis was conducted to compare running kinematics between the groups. RESULTS The LAS group exhibited fewer dorsiflexion angles and more inversion angles compared to the control group. Excluding the dorsiflexion deficits and more inverted ankles, there were no significant differences between the groups. CONCLUSIONS Although the ankle kinematic patterns found in this paper are not considered LAS risk factors, it will be able to identify precise LAS risk factors with prospective design (e.g., lower extremity movement patterns) as well as intrinsic risk factors.

PURPOSE This study examined the effect of sports life skills and life skills transfer of student-athletes and coaches, applying Actor-Partner Interdependence Model (APIM). METHODS Korean student-athletes and coaches from middle and high school sports teams participated in this study. There were 300 student-athletes (Mage=15.44, SD=1.64; male=218, female=82), with an average of 5.46 (SD=2.40) years of athletic career. Meanwhile, 33 coaches were (Mage=39.70, SD=8.36; male=26, female=7), with an average of 13.52 years of coaching career (SD=10.01). Measures included the Life Skills Scale for Student-Athletes (LSSSA; Jang et al., 2020) and Korean Life Skills Transfer Survey (KLSTS; Lim et al., 2018). Descriptive analysis, correlation, and APIM were undertaken by using the SPSS and AMOS programs. RESULTS First, the correlation between athletes’ and coaches’ life skills was not significant. Second, athletes’ life skills significantly affected their life skills transfer, similar to coaches’ life skills significantly affecting their life skills transfer. Fourth, coaches’ life skills did not significantly influence athletes’ life skills transfer, and the converse was not true either. CONCLUSIONS This study verified the effect of life skills development for two groups of athletes and coaches, on transfer in sports, and attempted statistical verification of whether it affects sports life skills and transfer between athletes and coaches. Although no statistically significant results were found in the partner effect, it is meaningful in that, it provided important implications for conducting a follow-up study on the relationship between athletes and coaches. In other words, it is expected to be a cornerstone for research on building a new model, along with investigating the interactive relations between athletes and coaches on life skills in the sports field.
目的应用行动者-伙伴相互依赖模型(APIM)，研究学生运动员和教练员运动生活技能与生活技能迁移的关系。方法以韩国初高中运动队的学生运动员和教练员为研究对象。学生运动员300人(Mage=15.44, SD=1.64;男性218人，女性82人)，平均运动年限为5.46年(SD=2.40)。同时，教练员33名(Mage=39.70, SD=8.36;男性=26，女性=7)，平均执教年限为13.52年(SD=10.01)。测量包括学生运动员生活技能量表(LSSSA);Jang et al.， 2020)和韩国生活技能转移调查(KLSTS;Lim et al.， 2018)。采用SPSS和AMOS程序进行描述性分析、相关性分析和APIM分析。结果第一，运动员与教练员的生活技能之间不存在显著相关。第二，运动员的生活技能显著影响其生活技能迁移，类似于教练员的生活技能显著影响其生活技能迁移。第四，教练员的生活技能对运动员的生活技能迁移没有显著影响，反之亦然。结论本研究验证了两组运动员和教练员生活技能发展对运动迁移的影响，并试图通过统计验证其是否影响运动员和教练员之间的运动生活技能和迁移。虽然在同伴效应方面没有发现统计学上的显著结果，但它的意义在于，它为开展运动员与教练员关系的后续研究提供了重要的启示。换句话说，它有望成为构建新模式的研究基石，同时也可以研究运动员与教练员在运动领域中生活技能的互动关系。

PURPOSE This study aimed to identify the lower limb muscle activity based on direction prediction presence or absence and gender during side cutting in healthy college students. METHODS The study participants included 14 healthy males and females (8 males; 6 females). All participants ran at full speed for a distance of 12m, and side-cutting was carried out at 45 degrees in a randomly indicated direction and in a fixed direction. Simultaneously, data regarding vastus medialis, vastus lateralis, semitendinosus, and biceps femoris muscle activity of the dominant leg were collected using an electromyography sensor, and data regarding vertical acceleration were collected using an inertial sensor attached to the pelvis. A sync webcam was used for obtaining the initial contact of side cutting and the stance period time. During the 10 milliseconds (pre-activation) prior to the initial contact and 50% of the stance phase (loading phase), vastus medialis, vastus lateralis, semitendinosus, and biceps femoris average muscle activity and hamstring to quadriceps ratio included as variables. RESULTS During the pre-activation and loading phase, the vastus medialis muscle activity of the male group was higher in the unexpected condition than in the expected condition. Furthermore, hamstring to quadriceps ratio was confirmed to be lower under unexpected condition compared to under expected condition during on loading phase. CONCLUSIONS The study results suggest that the risk of anterior cruciate ligament injury may increase with side cutting under unpredictable conditions. It is expected to provide useful information for identifying factors related to knee injury in the general population.

PURPOSE This study aimed to a) develop suitable screening tools for identifying gambling severity in Korea and b) explore factors that affect the gambling severity index in order to prevent Korean sports betting users from easily falling into gambling addiction, thus providing practical and useful guidelines in this regard. METHODS This study examined Korean sports fans who had experiences of participating in sports betting (Sports Toto), a legal sports betting system in Korea. Toward this end, an online survey was conducted from May 10 to June 25, 2022. A total of 214 questionnaire results, excluding 23 who gave insincere and/or incomplete answers, were analyzed for normal distribution through skewness and kurtosis, and subscale scores were calculated after performing exploratory factor analysis and reliability analysis using Cronbach’s α. RESULTS A psychological gambling severity index and behavioral gambling severity index were developed based on a stepwise regression analysis, which was conducted using the demographic characteristics of domestic sports betting participants and their lifestyle habits (e.g., smoking and drinking, problem gambling severity index, self-control scale, and gambling expectation scale). CONCLUSIONS First, factors affecting the psychological gambling severity index were identified (having a job, job stability, and security) along with lifestyle habits (smoking and drinking). Second, gender, occupational characteristics, full-time employment, confidence in self-control, and desire for self-improvement were indicated as significant factors that influenced the behavioral gambling severity index.

PURPOSE The quiet eye (QE) is defined as the final fixation time that is a specific target prior to initiating movement. This study aimed to identify the cause of QE in golf putting and to present an efficient practice method for improving putting skills. METHODS Thirty participants were randomly assigned to one of three groups. Each group practiced golf putting in different ways for two days. RESULTS The QE group showed a significant difference in putting scores, which was higher than that of the control group. The visual-occlusion group showed no difference compared to the other groups in terms of putting scores. The QE group showed a significant difference in terms of QE in the retention and competition tests compared to the pretest. The control group tended to have a slightly longer QE in competition tests compared to the pretest. The visualocclusion group showed no statistically significant difference in QE based on the period. All three groups had significantly longer swing times over the selected period. There was no significant difference in terms of the alpha power of the occipital lobe based on group and period. CONCLUSIONS The position of the visual-occlusion group became stable. However, the QE did not lengthen. The QE group had a longer QE. Furthermore, the control group that practiced with their eyes open tended to have longer QE. Therefore, QE may be related to visual-based cognitive processing rather than posturalkinematics. Finally, this study proved that QE practice is a more efficient method for novices in golf putting.
