This study was purposed to explore psychological change and regulation process during badminton competition. The data were conducted using group interviews and participation observations who 18 K college badminton players. The data were analyzed using open, axial, and selective coding based on grounded theory method (Strauss & Corbin, 1998). The results were as follows: Open coding results, 89 concepts, 44 subcategories, and 18 categories emerged as psychological change and regulation process during badminton competitions. Axial coding results, the categories are showed structural relationships such as performance, score, psychological momentum, the importance of competition, court environment, physical condition, competition strategy, psychological preparation, past experience, outcome expectation, psychological disturbance, psychological skills, game situation-changing strategy, support-seeking strategy, significant others' behavior, the opponents' behavior, psychological resilience, and maintenance psychological disturbance. Selective coding results, core category of this study was revealed to maintain psychological homeostasis. Environmental context during badminton competitions causes specific situations and events that evoke psychological disturbance. In turn, a player seeks mental and behavioral strategies to maintain psychological homeostasis. There is psychological homeostasis mechanism during badminton competitions for peak performance. Development of proper interest for psychological homeostasis will be improved through this research approach in sport psychology.
The purpose of this study was to examine the effect on Electro-chemical screen and anaerobic exercise capacity caused by short-term weight loss in amateur boxing players. Subjects of this study were 10 male university boxing player who conducted to weight loss methods. In 1st weight loss, boxing players took rapid weight loss during 5-7days, In 2nd weight loss, boxing players took weight loss 3kg during 2 weeks. The change of ECS and anaerobic exercise capacity were measured before and after weight loss period. Anaerobic exercise capacity was measured by 1RM of bench press and squat. In addition, using the wing-gate test muscle power and power endurance was evaluated. To find out the changes in ECS, urine and saliva was collected after waking up were analyzed. The results were as follow. First, 1RM of squat(p=.003), peak power(p=.023) and mean power(p=.015) showed significant decrease after 1st weight loss method. However in 2nd weight loss method, no factor of ECS and anaerobic exercise capacity were significantly decreased. Second, total urea(p=.015), urine rH2(p=.017), urine conductivity(p=.003), and utilization of vitamin(p=.005) showed significant decrease after 1st weight loss method. However in 2nd weight loss method, urine conductivity(p=.038) and saliva rH2(p=.028) showed significant increase after weight loss. In conclusion, amateur boxing players need a systematic weight loss to maintain optimal conditioning.
The importance of a health problem is emphasized in youth. Unfortunately, healthy activity physical education is not well utilized and is not popularly being researched. In order to improve these problems, this study attempted to explore the validity and applicability of SPARK program by designing and practicing the SPARK based P.E. classes. This study employed a mixed method research method based on a qualitative research strategy. Physical activity and physical fitness level were measured by accelerometers and FITNESSGAM. Additionally, empirical data were collected and analyzed by both Photovoice technique and recording. Findings of this study were divided into designing and practicing perspectives. First of all, the PE classes based on SPARK program was designed by 2009 national physical education curriculum and studies associated with the SPARK program. Further, I attempted to specify teaching strategy for enhancing physical activity level, power of execution and motivation. Second, PE class which has higher physical activity level, more participation and achievement, and successful fulfillment were emerged as consequences. Based on the study results, I discussed the validity and applicability of Physical Fitness based SPARK program and proposed suggestions for future studies.
PURPOSE This study first investigated how different types of sport team logos (emblem vs. mascot) influence consumer behavior through warmth and competence and then examined the moderating effects of consumer characteristics (gender) and contextual cues (perceived competence) on these relationships. METHODS A nationwide sample of adults age 20 was selected using quota random sampling based on gender. A 2 (logo type: emblem vs. mascot) × 2 (gender) × 2 (contextual cue: high competence vs. low competence) experimental design was employed, with participants randomly assigned to each group. Confirmatory factor analysis (CFA) with Mplus 8 was employed to assess the measurement model’s reliability and validity, and hypothesis testing was conducted through structural equation modeling (SEM), measurement invariance tests, and multigroup SEM analysis. RESULTS Findings indicate that anthropomorphized mascot logos, compared to emblem logos, generate more positive attitudes and psychological responses (warmth and competence) to the team. Gender’s moderating effect on the relationship between logo type and consumer perceptions (warmth and competence) was not significant, but contextual cues’ moderating effect was partially significant. CONCLUSIONS This study highlights of perceived warmth and competence’s crucial role in shaping consumer attitudes toward sports teams through logo design. These findings offer meaningful insights for sports teams and marketers to optimize branding strategies and enhance fan engagement.
This article aims to examine the research trend of sport history by analysing published research articles over the last decade in the Korean Journal of History for Physical Education, and suggest directions of research in sport history based on the results. We have reviewed a total of 264 articles relying on the analytic framework including the criteria of time period, method, nation, theme/topic, and purpose. The research findings are as follows. First, the post-Liberation period has been studied most often with 45.3%, followed by the Japanese Colonization period (20.2%), the Joseon Dynasty period (11.4%), the diachronic research (8.8%), the period from ancient times through Goryeo (8.1%), and the period of Enlightenment (6.2%). The results indicate that most recent studies in the journal unilaterally focus on the Modern and Contemporary history with 71.7%. According to the analysis result by research method, second, more than 90% of the studies have been conducted using qualitative methods while only 0.6% of the papers have adopted quantitative methods. The qualitative methods include textual analysis, participant observation, oral life story, and focus group interview. Textual analysis has been used most often with 74.5%. Oral life story has been second (22.5%), followed by participant observation (2.1%) and focus group interview (0.3%). The findings from this category show that it is still necessary to diversify research methods and vitalize interdisciplinary research. Third, in terms of nation, over 70% of the papers have studied about Korea, and European countries are the second most frequent region in the research trend (8.3%). The nation that follows is China with 6.4%. Although we analysed a Korean journal in sport history, the result exposes the lack of scholarly attention in the studies of sport history to world sport history reflecting comparative perspectives. By the criteria of theme/topic, fourth, genre has been studied most often with 31.7%, followed by figure (14.1%), facility/institution/organization (14.0%), system/policy/event (12.8%), philosophy/ideology/theory (6.7%), remains/relics/documentary material (6.3%), and domestic regions (5.4%). The results show that the recently published research articles have attempted to include a variety of genres in sports, play, and dance. While the topics for figure and facility/institution/organization also receive significant interest, it is limited that the studies mostly focus on male sport figures but female figures are barely explored. Even when female figures are researched, the attempts are observed only in the studies of dance. Fifth, the largest ratio of papers has had the research purpose of historical evolution (37.6%), followed by value/significance (20%), type/characteristic (15.5%), thoughts/ideology/theory (9.1%), origin (6.6%), suggestion/proposal/prediction (5%), comparison/correlation (5%), and concept/terminology (1.2%). The results expose that the studies tend to concentrate on historical evolution relying on chronological description while the research on concept/terminology is of little scholarly interest. Based on what we have found, it is identified that the recent studies in sport history have mostly focused on the historical evolution of a specific sport genre in the Korean Modern and Contemporary history using textual analysis. Consequently, the results suggest that researchers in sport studies need to put in additional effort to expand research topics and methods, and invite comparative perspectives involving inter/cross-national studies.
PURPOSE This study analyzed the effect of dynamic lumbar kyphosis on the biomechnical factors affecting the lumbar joints during deep squats. METHODS Thirty adults in their 20s who had experienced weight training for more than one year participated in this study (age: 23.4±3.5years old, height: 175.3±4.3cm, weight: 75.8±6.5kg, squat single repetition maximum (1RM) weight: 115.3±19.5kg). Under both restricted dynamic lumbar kyphosis (RDLK) and dynamic lumbar kyphosis (DLK), subjects completed one repetition of deep squats at a load of 70% of their 1-RM weight. To verify the consistency of deep squat movements performed under DLK and RDLK conditions, intra-rater reliability was analyzed using intra-class correlation . The biomechnical variables of the lumbar joint were calculated during DLK and RDLK deep squats. Paired sample t-tests (IBM SPSS 27.0, Armonk, New York, USA) were used for statistical verification. RESULTS During the deep squat movement performed in DLK and RDLK conditions, the peak angles of the ankle, knee, and hip joints, the minimum height of the pelvis, and the time and tempo showed statistically high reliability, confirming the accuracy of the movement. The peak flexion angle and moment, left flexion moment, left rotation moment, and compression force factors of the lumbar joint during deep squat were significantly lower in RDLK than in DLK. CONCLUSIONS Restricting lumbar dynamic kyphosis during deep squats is essential for decreasing the risk of lumbar joint injury.
PURPOSE This study aimed to examine the effects of motion analysis and image training using self-modeling with visual cues on the skill performance, imagery, and sports confidence of adolescent female soccer players. METHODS The participants were elite soccer players from two girls’ high school soccer teams divided into an experimental group (D girls’ high school, n=16) and a control group (I girls’ high school, n=13). The experimental group underwent motion analysis and image training when performing penalty kicks, short kicks, and long kicks using self-modeling with visual cues, while the control group underwent training using self-modeling videos without visual cues. Before and after the training, the evaluation score was calculated according to kick performance, and the imagery and sports confidence factors were measured. For the statistical analysis of all collected data, descriptive statistics, the Friedman test, the Mann-Whitney U test, and two-way repeated-measures analysis of variance were used. RESULTS First, on the motion analysis using self-modeling with visual cues, the experimental group’s penalty kick and short kick scores were improved and differed significantly, but no significant change was noted in long kick score. Second, as a result of image training using self-modeling with visual cues, all visual, kinesthetic, mood, and controllability factors of the experimental group improved except for the auditory factor, and the interaction effect was confirmed. In addition, the stated sports confidence of the experimental group was improved and the interaction effect confirmed. CONCLUSIONS The analysis of kick motion using self-modeling with visual cues was effective for the penalty kicks and short kicks of adolescent female soccer players. Moreover, this study confirmed that the analysis of kick motion improved the visual, kinesthetic, mood, and controllability sub-factors of imagery and significantly affected the players’ stated sports confidence.
PURPOSE This study aimed to establish a standardized evaluation of the consistency and reliability of the results of the 2018 Buenos Aires Youth Olympics. METHODS The results of the preliminary and the final rounds of the individual Boys and Girls competition of the 2018 Buenos Aires Youth Olympics were collected. Data were organized using Microsoft Windows Excel 2021. Windows SPSS 26.0 was used for descriptive statistics. Intraclass correlation coefficient calculation was used to analyze the evaluation score. The winner/loser decision, and the evaluation interrater agreement was confirmed using Fleiss' kappa. RESULTS There was a difference in the scores given by the judges in both the preliminary and final rounds of both competitions. A low correlation was observed between the decided winner of the judges, and the point variance for each item. CONCLUSIONS In the trivium value system, differences in the evaluation strategies of the judges may exist. Thus, improvements to standardize evaluation should be implemented. In addition, this scoring system considers various factors in the evaluation process, and the scoring system is complicated. Therefore, there may be a need to revise the evaluation system and find the optimal number of judges to create a better evaluation.
PURPOSE The purpose of this study is to section the stages of performance development based on the track and field athletes' performance records, derive the performance development span, which was a continuum of the development stages, and extract the psychological experience of the performance development span. METHODS In this study, 56 retired track and field athletes were provided with competition records, and 10 athletes participated in in-depth interviews. With the stage of performance development partitioned using long and short-term moving averages and regression slope in PRR, a continuous of performance development span was derived. To extract psychological experiences in the performance development span, a subject analysis was conducted after an in-depth interview. RESULTS First, the track and field athletes' performance development stage calculated short and long-term moving averages in the PRR. Based on the average difference in the regression slope of the initial 20% CPR in which the long-term moving average was not calculated, it was divided into beginning, rising, peak, and decline periods. Second, the performance development span was a continuum of the stage was of performance development, and the beginning period was 0 < PRR ≤ 7, it was a time when the competition record rises sharply. The rising period was 7 < PRR ≤ 60, which was a virtuous cycle time of growth athlete. The peak period was 60 < PRR ≤ 74, which was a time when the peak record was maintained. The decline period was 74 < PRR ≤ 100, which was a time when the competition record was downward. Third, throughout the performance development span physical intelligence of track and field athletes was based on their natural physical superiority, the technical skills rises and remains at its peak and then enters a downward trend. Competitional Intelligence aims to become personalization as it matures gradually while its competition management capability and game knowledge are immature. Psychological intelligence overcomes the initial psychological atrophy to form confidence, and after experiencing psychological burden at the peak, confidence decreases. In the environmental context, the competition record rises in the early stages, continues to rise, peaks, and enters a downward trend. CONCLUSIONS Track and field athletes' performance development span was implemented as a continuum of beginning, rising, peak, and decline periods, and the psychological experience of the performance development span formed a span of physical intelligence, competitional intelligence, psychological intelligence, and environmental context.
PURPOSE The main purpose of this study was to examine the difference in visual search strategies based on the skill level in success and failure cases in badminton short serves. METHODS To this end, six badminton experts (experience: more than 10 years) and six novices (less than 1 years) participated. The participants’ eye movement was recorded during each trial, and mean fixation duration, mean saccade amplitude, percentage of viewing time on each fixation location, final fixation duration, and gaze entropy were analyzed. RESULTS First, the mean fixation duration did not differ significantly, but the mean saccade amplitude increased when expert players failed to perform the serve successfully. Second, the percentage of viewing time on each location results showed that the overall viewing time was lower when the performance was unsuccessful, and the expert players fixated longer time viewing the net and space when they made a successful serve. Third, expert players showed longer QE than novice players when they made a successful serve. Finally, the gaze entropy results showed that expert players showed greater gaze entropy during successful performance, indicating that the gaze pattern was randomly distributed across trials. CONCLUSIONS When learning a badminton serve, we should fully recognize and explore the receiver’s location and external environment, and subsequently, before initiating serve movement, focus on the net or space between the receiver’s racquet and shoulders to make a more successful performance. In addition, we should make various patterns of the visual search strategy, rather than the fixed or consistent search strategy, to deceive receivers.
