Purpose The purpose of this sequential mixed-method study is to compare the levels of Moderate to Vigorous Physical Activity (MVPA) between the students with intellectual disabilities and students without disabilities in different types of inclusive physical education classes and to understand why different levels of MVPA occur. Methods For this purpose, 17 students with intellectual disabilities and 102 students without disabilities participated in this study, and the levels of MVPA in inclusive physical education classes were accessed using thee dimensional accelerometers. The collected data were analyzed using independent sample t-test. To understand the different levels of MVPA identified in quantitative analysis, four teachers were interviewed. Results Results showed that different levels of MVPA were found in inclusive physical education classes, and this is because the students with intellectual disabilities had participation constraints and teachers did not have knowledge to deal with those constraints. Considering gender difference, only different levels of MVPA were found among male students, which could be stemmed from few opportunities of cooperative works between male students with intellectual disabilities and male students without disabilities. Considering types of inclusive physical education classes, significant different levels of MVPA were identified in tee ball classes. The reason for this could be that the rule of tee ball is too complicated and too many team tasks for the students with intellectual disabilities to understand and to execute. Conclusions Based on the results, practical teaching strategies to increase levels of MVPA of the students with intellectual disabilities are provided in the discussion section.
PURPOSE This study aimed to analyze research trends in physical education within small schools from 1992 to the present, offering insights and directions for future research in this domain. METHODS To achieve this objective, we gathered data from 22 domestic journals utilizing keywords such as “small school,” “combined class,” “farming and fishing village,” “physical education,” and “sports.” Subsequently, the collected data encompassing topics, keywords, methods, subjects, and research areas, were organized using Excel. We employed the Word-Cloud program for the analysis of frequency by period and subject words by period. RESULTS Trends in physical education within small schools were categorized into three primary aspects: subject, method, and research area. Firstly, concerning research topics, the predominant focus centered on the application of teaching and learning as well as the curriculum management, with less emphasis on pre-service and incumbent teachers. Secondly, research methods shifted from quantitative to qualitative approaches starting in the 2000s. However, the utilization of qualitative research methods displayed limited diversity. Lastly, we analyzed the research area by classifying it into the region where the research subject is situated and the region to which the researcher belongs. The Gyeongsang and Gangwon regions constituted the majority in both categories, with over half of the researchers hailing from Gyeongbuk. CONCLUSIONS This study underscores the growing necessity for research into physical activity within small schools, given the increasing proportion of such institutions. It offers valuable insights for future research endeavors in the realm of physical activity within small schools.
Researchers and teachers in physical education have emphasized sportsmenship in sport education setting. However, how to teach sportsmenship in physical education is not proposed yet. The purpose of this study was (1) to develop an instructional program for teaching and learning sportsmanship and (2) to examine its effects on sportsmenship. Participants were 7th middle school students(N=95). Data were collected using Sportsmanship Test(Park, 2014), open-ended questionnaire and in-depth interviews with students. The data were analyzed through paired samples t-test and qualitative content analysis. Results showed that significant difference was observed in students' sportsmanship test scores after instruction. Analysis of interview data showed that students experience the value of utmost effort, respect for opponents, respect for teammates, acknowledging results, respect for judgment, and valuable lessons related to character education. Implications for sportsmanship education using instructional program were discussed.
Purpose The purpose of this study was to examine the effects of parents’ involved dance-sports program on a physical activity level and a fitness of children with a developmental disability and on their parents’ perception. Methods The participants were seven children with a developmental disability ranged between 8 and 16 years and seven parents of them participating in the dance-sports program during 90 minutes, 3 times per week for 8 weeks. The quantitative data (i.e., the physical activity level, the physical fitness, and the questionnaire) were collected before and after the intervention. Results The results showed that there was statistically significant difference of the parents’ perception on children’s participation in a physical activity [F=5.63, P<.04]. Although the experimental group showed increase trend, whereas the control group showed decrease trend, there was no statistically significant difference of the physical activity level and the physical fitness of the children with development disabilities. Conclusions Parent participated dance sports program seems to be effective on parents’ perception on children’s participation in a physical activity, physical activity level and the physical fitness of the children with a development disability in experimental group.
When the long-awaited KSME in PESS was established in 1998, KSME faced a turning point in its growth. Following the changes in both quality and quantity of the society's researches since its establishment and seeking for future themes is important for the society. This research analyzed the society's research trend using mainly the Korean Journal of ME in PESS. Then, by examining the physical fitness test, it proposed possible future themes for the KSME. This research also looked into the American Kinesmetrics’ contribution to Kinesiology, its research trend and future researches The KSME's recent researches show refined quality, diversified themes and reinforcements in practical researches. Regarding the themes, the reliability and validity of tests became predominant, sports analysis and physical activity emerged, and interest in measurement and evaluation in school PE was low. Possible research themes in the future are measurement and evaluation in school PE, game analysis and sport big data. The recent interest of the American Kinesmetrics was the cross validation of criterion-referenced physical fitness cut-off score, the validation of the guideline for physical activity, and the relationship between sedentary behavior and health. Possible future research themes of the American Kinesmetrics were the refinement of test methods, the effectiveness of the physical fitness test award system, and the application of the ubiquitous wearable technology.
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.
Recently, there have been diverse types of physical activities supported by government policy in S. Korea. However, these activities may not be effective if they do not reach to moderate to vigorous level. This study designed school physical education system based on SPARK program, which include traditional physical education, sports club based physical activity, after school physical activity, and Saturday physical activity, to evaluate its effectiveness associated with physical fitness and empirical meanings of physical activity. This study employed a mixed method research paradigm for better understanding. Among various mixed method paradigm stances, this study employed "blending strategy" for complementary analysis. First of all, the effectiveness in health condition was evaluated by quantitative data. Specifically, physical fitness and lifestyle were analyzed by Helmas, IPAQ, and Accelerometer respectively. Second, empirical meanings of physical activity were analyzed by both Photovoice and in-depth interview which are qualitative research method. The result of this study first showed that a specially designed school physical activity program based on the SPARK contributed to improve students' physical fitness and lifestyle as well, however, there were important differences between male and female students. Second, physical achievement, alteration of spatiotemporal meaning, and change of societal relationship emerged as important themes. Further, these themes showed that they played an important role to maintain students' motivation in physical activity and consequently physical activity promotion was invigorated in school. Based on these results, we synthesized investment factors and process factors and outcome factors respectively. Finally, we suggested alternative teaching methods and suggestions for following research to overcome gender issues.
Circadian rhythm (CR) is an intrinsic process that changes in a cycle of approximately 24h/day to maintain body homeostasis. It is mainly controlled by the central command through the suprachiasmatic nucleus, and modern society features can disturb the central CR, contributing to various diseases. Recent studies have provided evidence that extrinsic factors, such as regular physical activity (RPA) and timerestricted feeding (TRF), can also alter the CR peripherally, emphasizing RPA and TRF as the non-therapeutic methods for circadian misalignment (CM). Therefore, this review scrutinizes the regulatory mechanism of CR and summarizes the relationships between CM and various diseases. In addition, by reviewing studies investigating the prevention or improvement of CM via RPA and TRF, the value of circadian biology research that can directly affect health, physical function, and lifespan is summarized. By introducing the scientific evidence for RPA and TRF to maintain and improve CR, we tried to emphasize the importance of regular exercise and healthy eating habits to people in the modern world who have difficulty maintaining CR.
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 investigated the associations between mental health and physical activity with all-cause mortality in persons with disability. METHODS A total of 595 participants (39.3% women) aged 45≥ years, who participated in the Korean longitudinal study of aging (KLoSA) were included in this study. The Korean version of mini-mental state examination (K-MMSE) and the center for epidemiologic studies depression scale (CES-D) were used to assess cognitive impairment and depressive symptoms, respectively. The participants were classified into active and inactive groups based on physical activity of 150 min/week. Cox’s proportional regression analyses were used to determine the hazard ratio (HR) and 95% confidence interval (CI) of mental health and physical activity relating to all-cause mortality. RESULTS During the follow-up period (11.8±4.1 years), a total of 218 (36.6%) deaths occurred from all-causes. Participants in the inactive group had significantly higher cognitive impairment (p =0.046), depressive symptoms (p =0.001), and all-cause mortality (p=0.037) than those in the active group. Compared to participants in the normal (HR=1), cognitive impairment (HR=2.229, 95% CI=1.645-3.020, p<0.001), and depressive symptoms groups (HR=1.542, 95% CI=1.136-2.091, p<0.001), those in the inactive group had significantly higher HR related to all-cause mortality. However, in the active group, cognitive function and depressive symptoms were not associated with all-cause mortality. CONCLUSIONS The current finding suggests that the promotion of physical activity may play an important role in preventing premature death from all-causes in persons with disability, especially among those with mental health problems.
