The purpose of this study is to produce an analysis of content published in both academic literature and industry related publications that specifically examines the theme of sport sponsorship. Scholars suggest a gap between academia and industry, yet it is undetermined how published articles about sponsorship are aligned and why certain topics may overlap in interest where others are independent topics. While a number of other studies have examined content in academic publications, no study has yet been applied comparing industry publications. Our intention is to compare the published academic articles and what is written in industry publications to better understand the content that is being discussed across the various channels, and to see if there is a gap between industry and academia. Findings show academics focused on certain categories while industry focused on others. Within some categories there was a clear distinction in how differently they discussed certain topics. However, some categories did demonstrate balance.

The purpose of this study is to secure basic data for forecasting demand for new sports public services and to provide basic data on policy strategies for introducing new sports public services. This is achieved by predicting demand for the project using the Bass model, exponential smoothing method, and qualitative Delphi method. First, analysis of the demand for “National Physical Fitness 100” from the Bass model showed that the innovation coefficient was relatively low (0.029) compared to other physical fitness centers and that the initial service spread rate was slow. However, it was found that the imitation coefficient (0.332) was relatively high, the q/p value (11.45) was large, and that demand gradually increased. Secondly, the demand forecast based on the exponential smoothing method appeared more rapidly than in the Bass model. This is because the exponential smoothing method determines an exponential smoothing coefficient, which is an inclination value of the regression line, by the rate of change of existing data. Therefore, stable demand based on the exponential smoothing coefficient can be predicted and used as a basis for the initial demand forecast. Finally, the result predicted by the National Physical Fitness 100 expert Delphi method increased significantly in 2020 but has since become a gentle straight line. This can be interpreted as an expectation for an infrastructure expansion plan such as human resources and facilities, as the national physical fitness budget for 100 operations was to increase in 2020. The Bass model, the exponential smoothing method, and the Delphi method used in the research can thus confirm how the forecast results of the demand for National Physical Fitness 100 are spread by period. This can contribute to the policy decision-making process for efficient government budget management and effectively meeting social needs, as demand by period can be predicted over time from the point of introduction of the service.

The term “sports welfare” has been widely used in South Korean society for over a decade. In contrast, the academic definition of it remains largely undefined, which led to inefficiency in the policies regarding sports welfare. This paper quantifies the degree of sports welfare on a first-level division basis by developing a composite index model through three rounds of Delphi surveys and an Analytic hierarchy process. 5 Key factors and 13 sub-factors were identified to composite the Index, and the index values were calculated by applying data collected from national sources. As a result, most “Do”s scored higher than “Si”s overall, while South Jeolla Do showed the highest (109.5) and Sejong Si showed the lowest (92.1). We expect the results to shed light on the concept of sports welfare and provide guidance on comparing the sports welfare level between regions.

This qualitative study examined Korean college soccer players’ perceptions of and need for agents and the roles and competencies expected of them based on in-depth interviews with college soccer players. By exploring the significance of soccer agents as perceived by college soccer players, this study aimed to provide basic data necessary for training soccer agents for college soccer players and establishing regulations for college soccer agents. The research results can be summarized as follows: (1) The players interviewed generally showed a positive attitude toward soccer agents and were aware of the need for an agent; (2) the roles expected of an agent by college soccer players were different from those expected by professional soccer players: preparing opportunities to join Korean and foreign professional clubs, supporting and managing players, and facilitating smooth communication; and (3) the core competencies expected of a soccer agent by college soccer players were official agent certification, networks with professional soccer clubs, and understanding of the soccer industry. The results of this study highlight the need for stakeholder organizations in soccer to establish a systematic agent platform for college soccer players and take efforts to eliminate unregistered agents who engage in inappropriate activities. Qualified agent education and training for college soccer players will help protect them from unregistered agents and foster high-quality agency services.

The main objective of this article is to examine the validity of a French version of the Athletic Identity Measurement Scale (AIMS) with a sample of French varsity athletes according to different characteristics such as age, gender and types of sports activities practiced. To this end, 445 sports students answered a questionnaire measuring the degree of Likert-type sports identity on a 7-point scale. The sample included 272 men and 173 women with an average age of 21 years. Validation of the factor structure and internal consistency was tested by performing confirmatory factor analyzes and calculating Cronbach's alpha coefficient on the four different models most proposed in the literature. The results related to the exploratory and confirmatory factor analysis showed that the four AIMS models tested in this study are not appropriate for the French context. On the other hand, they made it possible to identify a measurement model composed of two factors; identities and exclusivity. For the two factors, no significant difference appeared between the subgroups of age, sex and the types of sports activities practiced. Therefore, the two-factor model identified in this research stands out from the already existing models. To further test its robustness, it would therefore be desirable to test it in socio-cultural contexts close to that of France.

This study aimed to identify sporting event experience factors and examine the structural relationships among experience, destination image, event image, and behavioral intention using data from sport spectators of the 18th FINA World Aquatic Championships in South Korea. The data were collected using a face-to-face questionnaire-based survey with 329 randomly selected sport spectators aged over 20 years. Factor analysis, reliability, validity, a correlation analysis, and a structural equation modeling analysis were employed utilizing SPSS 22.0 and AMOS 22.0. The results indicate that entertainment, esthetics, and escapism in sporting event experiences enhance destination image and event image. Further, destination image and event image are strong predictors of behavioral intention. The results indicate that local governments and event organizers should provide spectators with a creative sporting event environment with a wide array of potential experiences.

Several sportsmen are worried about achieving or sustaining their ideal body weight and distribution for their discipline. Players may wish to lose weight to improve effectiveness, enhance visual appeal, or participate in weight class activities. This culminates in attempts to lose body fat while decreasing muscle mass, as well as eating choices that can have serious health effects. A Ketogenic diet is rich in fat, low in carbs, and somewhat high in protein. Various nutrition-exercise combos have been evaluated in an attempt to boost oxidative stress rates while decreasing carbohydrate efficiency levels and improving overall exercise capacity. According to the findings, increasing fat availability leads to higher rates of whole-body and muscular lipid use during regular moderate-intensity aerobic activity. With significant increases in fatty acid oxidation levels, such diets regularly fail to increase stamina results in comparison to a carb diet, and nothing is understood to evaluate the impact of a Ketogenic diet on strength development. Consequently, the Ketogenic diet may be one of the most extensively researched and defined dietary regimes for losing weight. It is also becoming more popular as a long-term treatment for a variety of illnesses, including epilepsy and many others, and is a typical dietary pattern of Regional cultures. Considering these factors, as well as the reality that there are always sportsmen who choose to do, or are compelled to do, just about everything that that may provide even a slight benefit, protocols that provide that are known to be detrimental.

Lateral ankle sprain (LAS) is the most common injury in youth soccer. The mechanisms of LAS should be identified to develop effective injury prevention programs. Alignment and range of motion (ROM) are considered factors affecting kinematics during movement. Therefore, this study was designed to identify whether static measurements, including alignment and ROM, affect ankle kinematics related to LAS during running in youth soccer players. For this study, 100 participants were recruited. Data on rearfoot angle in the prone position (PRA), tibial varum, weight-bearing lunge test (WBLT), passive eversion, passive inversion (PIN), and ankle kinematics during running of all participants were collected. Ankle kinematics were computed for dorsiflexion at the initial contact (IC), inversion at IC, maximum dorsiflexion (MDF), and maximum inversion (MIN). Stepwise multiple regressions were conducted with an alpha level of 0.05. PRA, WBLT, and PIN significantly predicted dorsiflexion at IC (R2 = 0.144, P < 0.001), and PRA was a significant predictor on inversion at IC (R2 = 0.227, P < 0.001). PRA and WBLT were significant predictors on MDF (R2 = 0.330, P < 0.001), and PRA significantly predicted MIN (R2 = 0.188, P < 0.001). Of significant predictors, only WBLT can be treated by joint mobilization. Thus, WBLT related to pronation, which makes the ankle in a closed-packed position, should be treated to increase DF ROM and ankle stability. In addition, low-speed running video analysis might be useful in screening for ankle malalignment.
踝关节外侧扭伤是青少年足球运动中最常见的损伤。应确定LAS的机制，以制定有效的伤害预防方案。在运动过程中，定位和运动范围(ROM)被认为是影响运动学的因素。因此，本研究旨在确定静态测量，包括对中和ROM，是否会影响青少年足球运动员跑步过程中与LAS相关的踝关节运动学。在这项研究中，招募了100名参与者。收集所有参与者俯卧位(PRA)后足角、胫骨内翻、负重弓步测试(WBLT)、被动外翻、被动内翻(PIN)和跑步时踝关节运动学数据。踝关节运动学计算为初始接触时的背屈(IC)、IC时的内翻、最大背屈(MDF)和最大内翻(MIN)。采用逐步多元回归，α水平为0.05。PRA、WBLT和PIN能显著预测IC的背屈(R2 = 0.144, P < 0.001)， PRA能显著预测IC的反转(R2 = 0.227, P < 0.001)。PRA和WBLT能显著预测MDF (R2 = 0.330, P < 0.001)， PRA能显著预测MIN (R2 = 0.188, P < 0.001)。在重要的预测因素中，只有WBLT可以通过关节活动来治疗。因此，与踝关节内旋有关的WBLT，使踝关节处于封闭的位置，应该进行治疗以增加DF - ROM和踝关节稳定性。此外，低速跑步视频分析可能有助于筛查踝关节错位。

PRA and WBLT were significant predictors on MDF (R2 = 0.330, P < 0.001), and PRA significantly predicted MIN (R2 = 0.188, P < 0.001). Of significant predictors, only WBLT can be treated by joint mobilization. Thus, WBLT related to pronation, which makes the ankle in a closed-packed position, should be treated to increase DF ROM and ankle stability. In addition, low-speed running video analysis might be useful in screening for ankle malalignment.","PeriodicalId":93448,"journal":{"name":"International journal of applied sports sciences : IJASS","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90808270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined the performance differences in elite male marathoners when competing for record times versus ranks. Data of the top 300 male marathoners in 2019 were obtained from the World Athletics website for comparison and analysis. All competitions approved by the World Athletics were rated in the order of OW, GL, A, B, C, D, E, and F. Time comparisons were performed using one-way ANOVA and then the Bonferroni post-hoc test. Higher-grade competitions consist of top athletes with competitive qualifying record whose central motivation is to achieve the best records. Lower-grade competitions are often preliminary measures of qualification for larger competitions, motivating athletes to compete for ranks rather than records. The average time difference for each competition was statistically significant. GL's average time was the fastest at 2:13:42 (±00:03:15). From A to F, the average finishing time tended to increase from 2:09:51 (±00:03:27) to 2:14:48 (±00:03:24). The average end time at F was the slowest at 2:14:48 (±00:03:24). When comparing the athletes’ relative performance, the times for large international competitions, such as GL, A, and B, were also faster than smaller competitions, such as E and F (p<0.05). These results are interpreted to mean that competing to achieve record times is better for marathon performance than competing for ranks.
