All analyses were performed using SPSS 25.0, Kruskal-Wallis H tests were applied to observe the changes by training methods. Mann-Whitney U tests were used as Post Hoc. RESULTS The results indicated that running time and VO2max post-test improved compared to that for the pre-test for graded exercise test. The lumbar extension strength of the post-test was higher than that for pre-test. There was no significant difference in other variables. CONCLUSIONS It is suggested that nonlinear periodization strength training can be expected to improve running time, VO2max, and trunk strength for cross-country athletes; however, it does not affect the overall changes.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91088239","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}

As a result, the popularity of home training YouTube content, which shows how to use exercise equipment or workouts without professional influence, has also increased. Therefore, this study focused on the characteristics of YouTube home training content (specialization, diversity, and interaction), personal health awareness, exercise awareness, and expectation-confirmation model to identify which required exercise continuation intention through YouTube home training. METHODS SPSS and AMOS software were used to conduct frequency, reliability, and confirmatory factor analyses, as well as to conduct correlation analysis and construct a structural equation model.RESULTS First, health and exercise awareness had a positive effect on confirmation. Second, among the characteristics of home training content, only specialization had a positive effect on perceived usefulness. Third, confirmation had a positive effect on perceived usefulness and viewing satisfaction, perceived usefulness had a positive effect on viewing satisfaction and exercise continuation intention, and viewing satisfaction had a positive effect on exercise continuation intention, which proved the expectation-confirmation model in this study. CONCLUSIONS To increase exercise continuation intention through home training YouTube content, creators need to produce professional content that can stimulate viewers' internal motivation.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74485793","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}

METHODS Thirty-eight male players (age: 22.6 ± 1.12 years, height: 175 ± 3.54 cm, weight: 65.5 ± 5.11 kg) were included in this study, and chronic ankle instability was checked using Cumberland Ankle Instability Tool (CAIT) and Balance Error Scoring System (BESS). They were randomly assigned to the Visual biofeedback (Training group: TG, n = 19) and Y-balance groups (Control group: CG, n = 19) for four weeks. TG performed balance training using the Biodex balance system (BBS) and CG performed training using the Y-balance system. During jump landing, time to stabilization (TTS), force plate (COP, GRF); joint angle and moment were collected and analyzed. All analyses were performed with SPSS 21.0, and Bonferroni was used for repeated measured ANOVA and post-hoc. RESULTS The results indicated that there was an interaction between TG and CG in terms of AP and ML directions of TTS (p < 0.05). AP/ML TTS of the TG for the post-test was smaller than that for CG (AP: p = 0.000; ML: p = 0.046). ML TTS of the TG for post-test was smaller than at pre-test (p = 0.041), and AP TTS of the CG for ankle joint moment (p < 0.05). There was an interaction between TG and CG in terms of dorsiflexion (DF) and plantarflexion (PF) of joint moment (p < 0.05). Ankle moment of the CG for post-test decreased than at pre-test (DF: p = 0.040, PF: p = 0.032), and ankle dorsiflexion moment of the CG for post-test was decreased than at pre-test (p = 0.046). CONCLUSIONS Balance ability was achieved more effectively through visual biofeedback training than Y-balance training. Therefore, we recommend balanced training with visual feedback on chronic ankle instability.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91437406","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}

METHODS Twenty-one sports biomechanics questions (49 detailed questions) in the last 7 years (2016-2022) were classified into four types (evaluation content factors, classification of educational goal, sports application or not, classroom connection, and including calculation) and analyzed. RESULTS The recruitment exams had the following characteristics. First, only approximately 22.4% of the questions were related to the secondary physical educational field. Second, only 34% were sports-applied questions. In addition, according to Bloom's classification of educational evaluation, 36.7% of knowledge-level questions, 40.8% comprehension-level questions, and 22.4% application-level questions were accounted for. Finally, the questions tended to be considerably biased towards specific items (kinetics and kinematics understanding and application of linear and angular motion). CONCLUSIONS Sport biomechanics questions in the ‘Secondary Physical Education Teacher Recruitment 1st Exams’ should be based on questions that are likely to occur in the field of secondary physical education, to occur in real sports situations, and to be asked by students. Additionally, rather than asking for simple knowledge or comprehension, the proportion of questions in the application level should be increased.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85264816","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}

METHODS A total of 78 match videos and 1969 points of international competition over 3 years were analyzed for the nine major competitors of the national fencing team (Males = 5, Females = 4). The characteristics of each skill, body section and location according to the score were analyzed by dividing them into male and female groups. Data were analyzed using IBM SPSS ver. 25.0. RESULTS First, in the situation analysis according to the men's sabre score, attack skills were the most common in the winning situation (447 points, 73%) and in the situation of losing points (389 points, 72%); however, the difference was not significant. In the analysis of the piste location according to the score, B4 was the most common appearing 254 times (41.5%) in the scoring situation and A4, 243 (45%) times in the losing situation, with a significant difference (p < 0.001). Second, in the situation analysis according to the women’s sabre score, 315 attacks (70.6%) were found in the winning situation and 277 (74.7%) in the losing situation; however, the difference was not significant. In the analysis of the scoring body part, the Sixte area scored the highest with 121 points (27.1%), and the arm area lost the most points with 105 points (28.3%); however, the difference was not significant. In the analysis of the piste location according to the score, A4 was the most common in, appearing 179 times (40.1%) in the scoring situation, and 182 times (48.8%) in the losing situation, with no significant difference at the p < 0.001 level. CONCLUSIONS In the men's game, there were many scored points in B4 and many lost points in A4. In the women's game, there were many scored points and lost points in A4; therefore, the difference in goals and losses according to the piste position was confirmed. These results suggest that it is possible to infer the game management patterns of world sabre players and the flow of world fencing.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83927627","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}

This study examined how a sensational scene (accident) in a sport game influences the sponsorship effects through electroencephalography (EEG) analysis. METHODS The current study uses an experimental method. First, as an experimental stimulus, a video of F1 racing edited in a total of 9 min and 39 s was used, and an accident scene was inserted in the middle of the video. A total of 46 people participated in the experiment, and all participants watched the F1 video, including the accident scene. Participants' brain waves were observed in two prefrontal and two occipital lobes. The relationship between scene sensation and sponsorship effect was analyzed based on alpha waves and the sponsor brand recall measured by questionnaires. RESULTS First, the accident scene of the race caused the power of alpha wave to be abruptly reduced (i.e., alpha blocking). Second, the difference between the alpha power level of the group that recalled the sponsor brand and that of the group that did not recall was statistically insignificant; hence, the hypothesis was rejected. Third, the right-brain dominance (negative emotion) in the accident scene of the race was statistically insignificant; therefore, the hypothesis was rejected. Finally, the group that recalled the sponsor brand showed a left-brain dominance (positive emotion), which was statistically significant. CONCLUSIONS This study confirmed the marketing communication and neuromarketing theories on the sponsorship effects created by stimulation, attention, and memory in a sport sponsorship setting, observing alpha blocking phenomena in a sensational scene (accidents). In addition, it was revealed that the group that watched the same accident scene relatively positively and exited remembered the sponsor brand better than the group that did not watch it. The result implied that sport fan’s personal trait (e.g., sensation seeking) to sensation in sponsorship activities affects the sponsorship effect. The results also emphasized the importance of selecting target customers of sports fans in sponsorship to maximize sponsorship effects.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"237 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75850089","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}

METHODS Nine sport climbers who were able to perform at a climbing difficulty of 5.11d, were included in this study. Warm-up exercise consisted of myofascial release, pre-exhaustion exercises, and static stretching. Grip and back strengths were measured for muscular strength, and isometric muscular endurance of the finger flexors was measured as the time spent hanging on each hold according to the angle of the elbow joint. Repeated measures of ANOVA were performed to confirm the difference in treatment, and a significant difference between groups was confirmed by contrast test. RESULTS Myofascial release, pre-exhaustion, and static stretching before climbing did not affect muscle strength. However, the static stretching exercise significantly decreased isometric muscle endurance of the finger flexor at 90° open hold, and the pre-exhaustion exercise significantly decreased the hanging time at 180° crimp and slope grips. There was no effect on climbing performance according to the type of warm-up exercise. CONCLUSIONS Our findings suggested that various warm-up exercises did not directly affect muscle strength, muscular endurance, and climbing performance in sport climbers. Thus, we suggest that future research on complex warm-up exercises considering climbing postures should be conducted.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86165886","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}
