Purpose This study was conducted to investigate the appropriateness of the concept of condition for athletes and to conceptualize condition in a way suitable for field and then to produce a tool to test condition that reflects usability. Methods 30 college athletes and national athletes with more than 5 years of experience were selected. In the conceptual review stage, the appropriateness of the concept of condition was verified. In the conditional element collection stage, the condition concept reflecting usability was extracted. In the development stage of the conditional questionnaire, a condition questionnaire was developed in consultation with the data provider to reflect usability. Results Previous studies on the condition of athletes were complicated and the necessity for consideration of usability was raised. As a result of conceptualization with consideration of the application to the sport scene, condition in a scene is summarized into both physical and psychological states. As a result of the appropriateness evaluation of the tool that produced the condition inspection tool reflecting the condition element based on universality and peculiarity of conditionality, the athletes evaluated that the condition inspection tool properly reflects condition, is easy to apply and can be used for condition control. Conclusion The development and application of psychological testing instruments reflecting usability will accelerate the application of sports psychology in the appropriate direction. The reflection of usability will contribute not only to the reliability and validity of the psychological testing tools used in the field of sports psychology, but also to the improvement of the possibility of intervention by leaders and athletes, the convenience of development procedures, and the utility of response results.
Sport Imagery Questionnaire of Hall et al.(1998) was developed to investigate the imagery type of athletes objectively. The purpose of this research is to verify validity and reliability of Korean SIQ by using Rasch Model, in order to make up for complement drawback of SIQ which was developed only using factorial analysis. This research conducted first and second questionnaire survey. Second survey was conducted targeting different study participants from those of first survey. The participants of first survey was 265 athletes of Chungcheong Province, and the participants of second survey was 169 athletes of Chungcheong Province. SPSS 21, Winstep 3.62, and AMOS 18 was used for date analysis. The result of Rasch Model verification for the data of first survey revealed that 8 items of SIQ were unfit. Thus, 5 factors and 22 items were determined. 7 point Likert scale was revealed to be a good fit. The result of Confirmatory Factor Analysis for the data of second survey revealed that Construct Validity of 5 factors and 22 items was valid and reliability was high by recording Cronbach’α value .954. External Validity was revealed to be high by showing that correlation between sport confidence and MG-M imagery was high.
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.
PURPOSE This study aimed to investigate conditioning management and perception in Korea Ladies Professional Golf Association golfers and elite amateur female golfers. METHODS Physical characteristics and performance-related factors were investigated through a short version of the conditioning questionnaire consisting of 16 questions on five factors, surveying 129 female professional golfers and 174 elite amateur female golfers. The components of the questionnaire included physical fitness (four questions), injury (four questions), nutrition (three questions), mental (three questions), and performance strategy factors (two questions). Data were analyzed using IBM SPSS Statistics ver. 23.0 (IBM Co., Armonk, NY, USA). An independent t-test was used for comparison between groups. RESULTS Physical fitness-related factors showed significant differences in all four questions between groups (p<0.001–0.031), injury-related questions showed significant differences between groups in three questions (p<0.001–0.003), and one nutrition-related question was different between groups (p<0.001). CONCLUSIONS Differences were seen in conditioning management factors recognized between professional and elite amateur female athletes. Future research on conditioning questions and differences in effects according to actual performance will be needed.
PURPOSE This study aimed to develop a Korean version of the Low Energy Availability in Females Questionnaire (LEAF-Q) by translating the original English version into Korean using cross-cultural translation guidelines and conducting a face validity assessment. METHODS Following structured cross-cultural translation guidelines, a provisional final version (Pre-K-LEAF-Q) was created through initial translation, synthesis of initial translations, back translation, synthesis of back translations, and expert committee review. Additionally, its face validity was tested with 30 female participants. RESULTS After completing the translation process, the expert committee comprehensively compared each translation to finalize the Pre-K-LEAF-Q. This version was crafted to ensure semantic, idiomatic, experiential, and conceptual equivalence. Among the 30 females who participated, three noted that certain phrases were unclear or awkwardly expressed. The expert committee reviewed these five comments from the face validity test and modified three of the phrases. CONCLUSIONS The K-LEAF-Q was developed through cross-cultural translation and face validity testing to suit the cultural and linguistic context of Korea. It is expected to be a valuable tool for Korean female athletes.
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 the study was to determine difference of body composition, bone mineral density and health-related fitness by physical activity level in young women. Methods A total of 90 women aged 19-29 years participated in this study. The subjects were divided into three groups (low, middle, and high level) according to the physical activity level estimated by bone-specific physical activity questionnaire(BPAQ). Body height and weight were measured. Body composition parameters including four sites of bone mineral density(BMD) were estimated by DXA (Hologic, QDR-4500, USA). Health-related fitness tests was assessed using sit & reach, grip strength, sit-ups, and VO2max. Statistical analysis was performed using SAS version 9.4. All data were presented in terms of means and standard deviations. One-way ANOVA was applied to determine difference of dependent variables by physical activity level. Duncan's multiple range test was used as a post-hoc test. The statistical significance level was set at p < .05. Results There were significant differences on body weight(F = 4.867, p = .01), body mass index(F = 5.053, p = .008) and fat-free mass(F = 8.364, p = .0001) among the three groups. Significant differences were found on whole body BMD(F = 16.730, p = .0001), lumbar BMD(F = 11.480, p = .0001), femur BMD(F = 42.182, p = .0001) and forearm BMD(F = 5.560, p = .005) among the three groups. There were also significant differences on sit and reach(F = 11.433, p = .0001), sit-ups(F = 17.972, p = .0001), VO2max(F = 3.106, p = .05) and duration of GXT(F = 7.479, p = .001). Conclusions There were differences on body composition, bone mineral density and health-related physical fitness by physical activity levels. Nevertheless, the questionnaire used in this study was not able to judge participation in various exercise types including aerobic exercise or resistance exercise. Therefore, in the future study, longitudinal study considering various types of physical activity and dietary intake will be needed.
This study examined whether or not regulatory focus can predict motivation level. 141 Ssireum player completed Korean self-regulatory focus of Hong(2005)assessing their self-regulatory focus, and Behavioral Regulation in Sport Questionnaire(BRSQ) of Lonsdale, Hodge & Rose(2008) accessing motivation level based on self-determination theory. Artificial neural network analysis was utilized to find motivation factors that determine the regulatory focus, and the option was multi-layer perception. The result represented promotion focus predicted intrinsic motivation. Also, the prevention focus predicted extrinsic motivation. This result provided that self-regulatory focus can predict player’s motivation level and promotion focus related to intrinsic motivation.
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 The purpose of this study was to investigate the association of physical activity level with insomnia severity (Normal, Subthreshold, Moderate and Severe) in adolescents and to use it as a basis for insomnia prevention. METHODS This study was conducted on a cohort of 50 adolescents under the age of 20 (19 males, 31 females) recruited from Hospital N in Incheon, Korea. Participants were categorized into groups according to the severity of insomnia in both males and females using the Korean version of the Insomnia Severity Index-Korean (ISI-K). The Korean version of the International Physical Activity Questionnaire was also used to calculate participants’ weekly moderate and vigorous physical activity. RESULTS The participants’ characteristics did not differ by insomnia severity in males, but there were significant differences in weight (p=.008), BMI (p=.019), SBP (p=.004), and DBP (p=.019) in females by insomnia severity. In male adolescents, there was no significant difference in the amount of physical activity by insomnia severity, but there was a trend toward decreased amount of physical activity with increasing severity. Among female adolescents, there were significant differences in the amount of physical activity by insomnia severity: moderate (p<.05), high (p<.05), and moderate-high (p<.05). In the unadjusted model, adolescents who did not meet the recommended amount of physical activity (150 minutes per week) were more likely to have insomnia (OR=4.67, 95% CI=1.34–16.24) than those who met the recommended amount of physical activity. The model after adjusting for covariates (gender and body mass index) also showed an association between the recommended amount of physical activity and insomnia (OR=3.94, 95% CI=1.17–13.28). Negatice correlations was found between insomnia index and moderate-to-vigorous physical activity (r=–.357, p=.013). CONCLUSIONS Adolescents are approximately 4.67 times more likely to suffer from insomnia if they do not meet physical activity recommendations, and there was a negative correlation between the insomnia index and moderate-to-vigorous physical activity, suggesting that physical activity should be increased to reduce the insomnia index.
