Purpose The purpose of this study is to investigate the factors for setting proper training duration of frequency that can guarantee the student athletes' right to study and performance, and to derive the ranks of setting proper training duration of frequency of student athletes by school level. Consequently, to provide basic data for the development of training guidelines for the growth period of Korean student athletes. Methods Delphi and Analytic Hierarchical Process(AHP) techniques were used. The Delphi survey was conducted in three phases, and collected data through Delphi survey were computed by SPSS win ver. 22.0 and Excel, using the mean, standard deviation, median, and coefficient of variation. Using the AHP technique, we classified the factors for setting proper training duration of frequency derived through Delphi survey, and calculated the importance by using Microsoft Excel 2010. Conclusion First, elementary students should be guaranteed regular class participation, have basic after school training, and be provided with adequate rest so that they do not lose interest in the exercise. Second, middle school students are required to decide whether to continue exercise based on their ability to exercise and abundant experience. Therefore, when abandoning the exercise, students should be able to faithfully carry out their academic performance. Third, high school students are directly related to college entrance and employment, so they have to concentrate on performance rather than on academic performance.
The purpose of this study is to examine the level and difference of sport personalitys of middle school students depending on their quality of sport participation. According to prior research(박정준, 2012; Beller & Stoll, 1996), we decided that faithfulness, cooperation, justice and consideration are the sub-components of sport personalities. The reliability and validity of the Sport Personality Index Questionnaire was verified through Cronbach's α test and confirmatory factor analysis. The survey was conducted from students (n=768) in an urban area of Seoul, thereby level and differences of sport personality were analysed by t-test, one-way ANOVA, and frequency analysis. As a result, male students had higher sport personalitys than female, with regard to the participants'grade, frequency and duration of sports involvement. Disparities of gender and grade were revealed due to the frequency and duration of their sports participation. Regarding the effectiveness of sports activities, school-directed sports activities such as the after school sports programs or mandatory sports club activities had barely influenced building sport personality. In order to build students'sports personalities, specific strategies are sorely needed to increase girl's participation and to enlarge opportunity for regular and consistent participation of middle school students. Moreover, in order to develop participants'sport personality within school-directed sports activities, those programs'development and implementation should be deliberately approached with pedagogical intention and organization.
Recent studies focus on Metabolic Equivalent Task (MET) to measure levels of and areas of peoples’ physically active lifestyle because MET more readily translate peoples ’subjectively perceived physicality into standardized scores. MET also allows researchers to clearly understand the relationships between peoples’ physicality and psychological variables. Thus, the purpose of this study was to understand the levels of and areas of MET among Korean middle school students and to analyze the relationships between MET scores and physical self-efficacy. A total of 278 questionnaires were analyzed using SPSS 18.0. Exploratory factor analysis, descriptive analyses, and regression analyses indicated that middle school students’ physically active lifestyle occurred in the order school, leisure, housework, and transportation areas. Female students did more physical activity in the areas of housework and transportation, compared to male students. In contrary, male students did the majority of physical activity in the areas of school and leisure. Physical self-efficacy affected students’ MET scores, especially for vigorous intensity activity. With regard to gender differences, physical self-efficacy affected male students’ MET scores in the area of leisure while female students’ MET scores were affected in the areas of school and housework. The results were discussed in light of methodological and pedagogical perspectives, and future research suggestions were provided in the discussion.
PURPOSE This study conducted a longitudinal analysis of physical activity levels and characteristics of middle-school boys and girls over a three-year period before and after the COVID-19 pandemic. METHODS This study used a sequential mixed-methods research design. In the quantitative study; three-dimensional accelerometers were used to measure weekly physical activity and sedentary time over three years (2019, 2020, and 2021) among 33 middle-school boys and girls, and the data were analyzed using repeated measures analysis of variance. In the qualitative study, data were collected and analyzed through focus group interviews with five participants. RESULTS The quantitative study indicated a significant increase in sedentary behavior and significant decrease in low-intensity activity and MVPA during the first year of the COVID-19 pandemic. In the second year of the pandemic, no significant difference was observed in sedentary behavior, low-intensity activity, and MVPA compared to the data collected in the first year. During the pandemic’s first year, qualitative study identified the following physical activity problems: “lockdowns,” “sedentarization of leisure,” and “reduced structured physical activity.” The following reasons were identified for the lack of improvement in physical activity during the second year: “intensified sedentary lifestyle habits,” “weak social networks,” and “lack of energy to exercise.” CONCLUSIONS The COVID-19 pandemic has led to a significant decrease in physical activity and a significant increase in sedentary behavior among middle-school students in South Korea, and even as the environments for physical activity have recovered, the physical activity problems of the early stages of the pandemic have not improved.
Purpose The purpose of this study is to measure the daily physical activity of male and female middle school students according to the period (VD: vaction day, SNPE: school day no PE, SPE: school day with PE) by using 3-axis accelerometer, and to compare the characteristics of adolescent physical activity according to gender and period. Methods The subjects were 130 middle school students (68 male, 62 female students). Data collection was performed using a 3-axis accelerometer(GT3X model, ActiGraph). Collected data were converted into time by intensity and rate using physical activity analysis program (Actilife v6.11.9) and analyzed by statistical program (SPSS 25.0). One-way ANOVA and independent sample t-test were used for statistical analysis. Tukey's HSD was used as a post analysis. The statistical significance level was .05. Results As a result, during each periods(VD, SNPE, and SPE), except for MVPA(moderate to vigorous physical activity) time on SPE, sedentary and MVPA time were significantly higher in female students, and low intensity and total physical activity time were significantly higher in male students. For male students, total physical activity time was higher in the order of SPE, SNPE, and VD, and for female students, physical activity time during the semester(SNPE and SPE) was significantly higher than VD. For male students, MVPA time was significantly high in order of SPE, SNPE, and VD, and for female students, it was high in order of SPE, SNPE, and VD but only significant difference occurred between SPE and VD. For both male and female students, sedentary time was high in the order of VD, SNPE, and SPE, but the sedentary time during vacation was significantly higher than during the semester. Conclusions When summarizing the results, first, it was confirmed that school and physical education classes as a physical activity space play a significant role in physical activity, especially MVPA, of male and female middle school students, second, the physical activity effect of physical education class was found to be more effective in male students. Based on the results of this study, it is necessary to conduct studies on various grades and to explore various factors affecting physical activity in a complex way.
Purpose The purpose of this study was to investigate characteristics of levels of physical activity in considering gender and different types of competition-oriented physical activity classes using three-dimensional accelerometers. Methods A total of 981 students(505 male students, 476 female students) in six different types of physical education classes were participated in this study. All of the six different types of physical education classes were competition-oriented classes, and levels of physical activity were accessed by three-dimensional accelerometers. Data were analyzed using t-test and ANOVA. Results First, descriptive analyses of participation time of levels of physical activity showed that MVPA of physical education classes is 10.26 mins (22.89%) on average, and, MVPA showed differently in different types of physical education classes in the order of T ball(14.61 mins), flying disk(12.61 mins), soccer(10.78 mins), volley ball(10.56 mins), basketball(9.64 mins), and table tennis(5.73 mins). Second, female students showed significantly lower levels of MVPA in all the different types of physical education classes. Third, post-hoc analyses showed that significantly higher levels of MVPA were found in T ball physical education classes and significantly lower levels of MVPA were found in table tennis physical education classes, compared to other types of physical education classes. Conclusions MVPA in physical education classes is not satisfied with recommended MVPA, and MVPA in Korean physical education classes is lower than MVPA in same types of physical education classes in other countries. In addition, significant mean differences of MVPA are found between male and female students, and new sports physical education classes show higher levels of MVPA compared to classic sports physical education classes. These results indicate that competition oriented physical education classes widely used in Korea need to find ways to increase MVPA and to overcome different levels of MVPA between male and female students.
Purpose The purpose of this study is to explore the Instructor’s adaptation process of school P.E. environment in middle school sports club and to develop substantive level theory. Methods For this purpose, 17 sports instructors who had worked for more than 3 years at the middle school in Seoul were selected as research participants. The method of this study is the Grounded theory(Strauss & Corbin, 1990). Results The results of this study are as follows. First, as a result of open coding, the instructor's adaptation process of the school P.E. environment was organized into 104 concepts, 30 sub-categories, and 15 categories. Second, as a result of axial coding, a paradigm model for the adaptation process of the school P.E. environment was formed. Third, as a result of the selective coding, created the storyline of the adaptation process and made the core category, ‘instructor's adaptation process of the school P.E. environment in middle school’. Four types of adaptation process such as 'Acceptance type', 'Effort type', 'Compromising type' and 'Abandoning type' are derived through the formalization applied to the hypothesis of the core category. Conclusions Based on these results, the developed substantive level theory was evaluated and summarized.
[Purpose] This study aims to examine necessity and characteristics of the K-OVEP, and discuss ways of settle and spread the program stably through cases applied in school settings. [Methods] To do so, educational components and curriculum of the K-OVEP was represented by analyzing references, developmental materials, and program application. This study was examined through the application process and observation of long-term program of the K-OVEP from two types of educational fields, 2 elementary schools and 2 middle schools. In order to examine if the K-OVEP achieves the aim of the IOC and the K-OVEP, basic level study was conducted to 187 students who participated in the program in 2016. The questionnaire consisted of three categories; ‘cognition part’ through the Olympic games and the Olympic values, ‘value part’ regarding five educational themes of the OVEP, and ‘interest part’ asking interest and involvement in sports activities, participants answered the questionnaire before and after the education. [Results] We found that K-OVEP is an integrated value based educational program regarding Olympics, stresses personality education, encourages students to explore their career, and is a process oriented education. The results showed that the K-OVEP achieved the educational goals in every categories and questions, and educational effects in sports activity looked different among schools and the environments. [Conclusion] This study was performed to participants at first year of the introduction of the K-OVEP, so in order to keep track of learners’ significant change continuously, expansion of participants, steady development of various new programs, development of assessment tools, experts training and follow-up studies will be required.
PURPOSE The purpose of this study was to analyze the level and characteristics of physical activity (sedentary, light, and MVPA) of high school students according to physical education (PE) class (DWPE: days with PE class, DNPE: days with no PE class) and sex. METHODS Data were collected on 147 students (65 male and 82 female) from four high schools in Seoul city, and physical activity was measured using a three-dimensional accelerometer. The collected physical activity data were input into SPSS 25.0, and the descriptive analysis and two-way ANOVA according to PE class and sex were performed. RESULTS The descriptive statistical analysis showed that 31% (40.7% male and 23.4% female) of participants met the recommended physical activity durations (MVPA of 60 min/day). In the two-way ANOVA, sedentary activity, light activity, and MVPA showed statistically significant main and interaction effects according to PE class and sex. According to the results of the interaction effect analysis, the gap in physical activity between DWPE and DNPE was large in male students. For male students, light activity and MVPA significantly increased on the day of the PE class, and sedentary activity significantly decreased. However, for female students, DWPE and DNPE did not differ significantly in all levels of physical activity. CONCLUSIONS In conclusion, the level of physical activity of Korean high school students was relatively low, and the effect of daily-life physical activity in the PE class was limited to male students. Accordingly, an alternative should be introduced to increase the physical activity of female high-school students through PE classes.
