PURPOSE Sport pedagogy (SP) has established itself as a subdiscipline in Human Movement Studies since the 1970s. It has become an academic labyrinth as a result of its rapid flourishing. Most researchers are extremely confused about this disorderly research complex. This study aimed to evaluate the characteristics of SP in stages in the western (mostly English speaking) countries. METHODS Analysis of literature published in English from 1990 to 2022. RESULTS The developmental versions were divided as follows: SP1.0 is positivistic in nature, SP2.0 is multi-paradigmatic as it includes all paradigms, and SP3.0 (current version). Many academic journals have been launched, and a variety of books on divergent topics are being published. Currently, research has exploded. In SP3.0, research performed by British scholars are notable in terms of number and quality, overpowering those by scholars in the USA and other countries. Youth sport and sport coaching are regarded as new legitimate areas. Additionally, signs for SP4.0 have been indicated. CONCLUSIONS In order to find way outs in the SP labyrinth, it is necessary to recognize the current research trends in international SP.
PURPOSE This study aimed to categorize consumers’ subjectivity on public value of citizen professional football club. METHODS Q-sample and Q-classification charts were developed based on theoretical background of the public value of citizen football clubs, and in-depth interviews with consumers were conducted using the Q-methodology. Q-classification and Q-factor analyses were conducted by selecting local residents as P-samples. RESULTS The public value of citizen football clubs was confirmed as ‘Type I: club-city win-win’, ‘Type II: social integration’, and ‘Type III: culture-led’. These types are contrary to previous studies that mainly focused on management and marketing, such as financial profitability and soundness, regional economic impact, and commercial value. This is the result of examining the public value of the citizen football club from based on the subjectivity of consumer, and it differs from that in previous studies. CONCLUSIONS This study reconfirmed the specificity and role of citizen football clubs in commercialized professional sports. It showed that citizen clubs must adopt organizational goal and operation method that are different from profit sports organizations (clubs).
PURPOSE The current study examined how baseball fans evaluate a robot umpire from the perspective of the human-robot interaction. In particular, this study examined whether baseball fans evaluated more positively a robot umpire depending on whether a robot or a human umpire has the final authority to make ball-strike decisions, when the ball-strike decision contradicts with each other. Furthermore, the different types of expertise (baseball vs. image analysis) embedded in robot umpire and fans’ levels of technology adoption were used to examine the relationship between umpire type and evaluations of robot umpire. METHODS This study used 2 (final decision maker: robot vs. human umpire) by 2 (different types of expertise embedded in robot umpire: baseball vs. image analysis) by 2 (different levels of technology adoption: low vs. high) between-subjects design. RESULTS The results indicated that when a robot umpire had the final authority to make ball-strike decisions, baseball fans evaluated more positively the adoption of robot umpire, when image analysis expertise was embedded in the robot umpire rather than baseball expertise. Meanwhile, baseball fans evaluated more positively the adoption of robot umpire when baseball expertise was embedded in a robot umpire rather than image analysis expertise. CONCLUSIONS The current study provides meaningful implications regarding how to design an effective system for the operation of robot umpire in baseball.
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 This study aimed to investigate how a 10-week online live Pilates training held during the COVID-19 pandemic affected body composition, cardiovascular function, and physical fitness in sedentary middle-aged obese women. METHODS Thirty obese women, aged 30 to 49 years (BMI : 25kg/m2 or more; waist circumference: 85cm or more) who were leading a sedentary lifestyle for more than 8 hours a day were assigned to one of two groups—that is, the Pilates training group (TR) and the control group (CON). Four participants were dropped from the study during the intervention period. Participants in the TR group (n=13) performed online live mat Pilates exercises (3 sessions per week; 60 minutes per session for 10 weeks, whereas participants in the CON group (n=13) were asked to maintain their normal lifestyles during the same intervention period. Independent variables related to body composition, cardiovascular function, venous function in the lower body, physical fitness, and 1-RM (repetition maximum) were measured at pre-test and post-test, and data were compared between the two groups and between the two tests. RESULTS 1) Regarding body composition, body weight, body mass index, fat mass, and waist circumference decreased significantly in the TR group. 2) Regarding cardiovascular function, stroke volume and cardiac output increased significantly in the TR group, and total peripheral resistance decreased significantly in the TR group. 3) Regarding venous function in the lower body, blood flow velocity and blood flow volume of the parenchyma area increased significantly in the TR group. 4) Regarding physical fitness, cardiorespiratory endurance, muscular endurance, flexibility, and balance improved significantly in the TR group. 5) 1RM of biceps curl, lat pull-down, leg curl, and leg extension increased significantly in the TR group. CONCLUSIONS It was concluded that the 10-week online live Pilates training had positive effects on the body composition, cardiovascular function, venous function in the lower body, and physical fitness of middle-aged obese women leading sedentary lifestyles.
PURPOSE In this study, in-depth interviews were conducted with track-and-field athletes and leaders who participated in the Tokyo Olympics. The study aimed to present practical measures for the development of Korean track and field, which people at the forefront of Korean track and field thought. METHODS In-depth interviews were conducted using semi-structured questions for a total of five track-and-field national athletes and four track and field coaches. RESULTS A total of 39 subcategories and 104 concepts were derived with regard to four research questions: the process up to the Tokyo Olympics, the actual condition of Korean track and field, a comparison with track-and-field power nation, and practical measures for becoming track-and-field power nation. CONCLUSIONS Practical measures are needed to improve and develop the competitiveness of Korean track and field, which is expected to improve its competitiveness and help develop Korean track and field in the future.
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.
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 research explores the underlying mechanism that determines how people perceive their goal progress and its relation with their motivation and self-efficacy. METHODS Three hundred and sixty Koreans who participated in an online survey were given salient individual exercise goals (11 workouts), and they reported their self-efficacy, goal progress perception, and motivation. We conducted dummy variable multiple regression analysis (2 [absolute progress-low (27%) vs. high (73%)] X 2 [categorization vs. no-categorization]) and multiple moderated mediation analysis based on Process Model 7 and 21 (Hayes, 2017). RESULTS The findings showed significant interaction between categorization and absolute progress on progress perception. In low progress condition, the categorization group perceived more progress than no categorization group and contrary effect in high progress condition. For motivation, in low progress condition, categorization group was more motivated than no categorization group, and inverse effect in high progress condition. Moreover, there was no direct effect, but only low self-efficacy group played the moderating role between perceived progress and motivation in conditional indirect effect. Lastly, the result indicated significant multiple moderated mediation effect. CONCLUSIONS This research theoretically contributes to the domains of categorization and motivation. Sport marketers can utilize categorization as a strategy by breaking down yearly memberships into monthly categories based on consumers perceptions. Future research can include subsequent motivation after a superordinate goal is completed.
PURPOSE The purpose of this study was to investigate the effects of 8-week aerobic exercise and polyphenol intake on body composition, cardiovascular response, vascular endothelial function, and physical fitness at rest and during exercise in prehypertensive men. METHODS The study included twenty-eight males in their 20-30 years of age with prehypertension. Participants in the aerobic exercise + polyphenol intake group (EX + PP; n = 14) performed aerobic exercise three sessions/week, 30 min/session, at 65% of the heart rate reserve, and consumed polyphenol (grape seed extract 300 mg) for 8 weeks. Participants in the aerobic exercise + placebo intake group (EX + PL; n = 14) performed the same aerobic exercise; however, they consumed placebo instead of polyphenol. All independent variables were measured at pre-test and post-test, and the data were analyzed. RESULTS The main results of the study were as follows: 1) SBP and MAP at rest decreased significantly in EX + PP, while MAP decreased significantly in EX + PL group. 2) In the EX + PP group, CO increased significantly, whereas DBP, MAP, and TPR decreased significantly during the hand grip exercise. In contrast, CO decreased significantly, while DBP and TPR increased significantly in the EX + PL group during the hand grip exercise. 3) Regarding vascular endothelial function, % FMD increased significantly in EX + PP group. 4) Sit-up increased significantly in both EX + PP and EX + PL groups; however, sit-and-reach in EX + PP group was significantly higher than that in EX + PL group at post-test. CONCLUSIONS The findings of this study showed that the 8-week aerobic exercise would have positive effects on body composition, cardiovascular response, and physical fitness at rest and during exercise in hypertensive men. Additionally, polyphenol intake would contribute more towards reduction of blood pressure at rest and during exercise and improvement of vascular endothelial function.
