PURPOSE High blood pressure and obesity pose significant health problems for older individuals. Previous studies showed that regular exercise improves physical fitness factors and decreases blood pressure and obesity. Therefore, this study investigated differences in blood pressure and obesity according to the physical fitness level of Korean older individuals using the National Fitness 100 data and used them to recognize the importance of maintaining physical fitness through regular physical activity or exercise for older individuals.METHODS From 2013 to 2019, a total of 218,848 subjects (men=74,271, women=144,577) aged ≥65 years who participated in the National Fitness 100 had their muscular strength, muscular endurance, cardiorespiratory endurance, balance, coordination, and flexibility measured, and they were ascribed a fitness level. Blood pressure, body mass index (BMI), percentage of bodyfat, and waist circumference were measured to compare the difference in fitness level.RESULTS There was a significant difference in the systolic and diastolic blood pressure in older men, and the diastolic blood pressure of older women by the fitness level (p<.001). In both older men and women, there was a significant difference in BMI, percentage of bodyfat, and waist circumference according to the fitness level (p<.001).CONCLUSIONS In conclusion, men and women showed different aspects in blood pressure, but Korean older individuals with having a high level of fitness managed their weight and body fat well. The decrease in obesity and improvement of physical fitness through regular physical activity and exercise could be a positive effect on maintaining health and extending healthy life years.

PURPOSE Blood pressure (BP) in hypertensive individuals is reduced by the accumulation of post-exercise hypotension (PEH) induced by a long period of training. This study aimed to investigate the effects of intensity of two different aerobic exercises with identical energy expenditure on post-exercise blood pressure and cardiovascular function in prehypertensive men.METHODS Eleven prehypertensive men in their 30s participated in two trials repeatedly. In the first trial, the exercise was moderate in intensity and continuous (MICE) with 70% of VO2max, and the exercise in the second trial was high-intensity interval exercise (HIIE) with 50% and 90% of VO2max. Each exercise was performed for 30 min, and the variables related to BP and cardiovascular function were measured at certain times for 1 hr during the recovery phase.RESULTS Our main findings are as follows: (1) Systolic blood pressure was significantly lower at 30 and 45 min of recovery time than the baseline in the HIIE trial, and systolic blood pressure was significantly lower in the HIIE trial than the MICE trial at 10, 15, and 30 min of recovery time. (2) The rate pressure product was significantly higher in the HIIE trial than the MICE trial at 15, 30, 45, and 60 min of recovery time. (3) The heart rate was significantly higher in the HIIE trial than the MICE trial at 15, 30, 45, and 60 min of recovery time. (4) Stroke volume was significantly lower in the HIIE trial than the MICE trial at 30 min of recovery time. (5) Cardiac output was significantly higher in the HIIE trial than the MICE trial at 15 min of recovery phase. (6) Total vascular conductance was significantly higher in the HIIE trial than the MICE trial at 15 and 30 min of recovery phase. (7) Total peripheral resistance was significantly lower in the HIIE trial than the MICE trial at 15 and 30 min of recovery phase.CONCLUSIONS The HIIE shows a higher cardiovascular stress than MICE; however, HIIE contributes to the augmentation of PEH and improvement of cardiovascular function. Therefore, HIIE rather than MICE should be suggested in BP control and enhancement of cardiovascular function in prehypertensive males.

PURPOSE This study aimed to explore the ranking culture of Korean female professional golfers under the assumption that side-effects such as performance degradation and sports desocialization result from the culture.METHODS To collect data, semistructured, open-ended interviews were conducted with eight former KLPGA Tour players, and the data were analyzed through the inductive analysis method suggested by Hatch (2002).RESULTS Our findings were the following: (1) There has been an oppressive culture regarding the salutation attitude among Korean female professional golfers. (2) The ranking culture of Korean female professional golf players formed a background of voluntarily noticing seniors from junior players. (3) As part of subduing juniors who go against the hierarchy culture, the phenomenon of group bullying by senior players was found. (4) There are players who influx the KLPGA tour after their tour career in foreign countries becomes uncomfortable with the ranking culture of Korean female professional golfers, or in worse cases, they leave the tour because of maladaptation. (5) Rather than protesting or raising issues, parents of players, especially those of junior players who have suffered damage against the ranking culture tend to accept the practices and endure disadvantages.CONCLUSIONS Follow-up studies on ways to improve them and additional studies on ranking culture and side-effects that may occur between athletes in other sports are required to restore the ethics of Korean sports and ultimately normalize them.

PURPOSE This study aimed to explore the effective and pragmatic idea regarding the development of physical education teacher education (PETE) programs in China. These programs share both similarities and differences in China and Korea, and they are also discussed here.METHODS Six universities reflecting the regional specificities of Korea and China were selected following consultation with experts. Data collected through in-depth interviews, non-participatory observation, literature, and local documents were analyzed and interpreted by using the comparative analysis research method.RESULTS First, when comparing the curriculum, which was divided into liberal arts, major, and teaching subjects in both countries, the ratio of liberal arts and teaching subjects was similar in Korea following major subjects. As for China, major subjects came in first, followed by liberal arts and teaching subjects. Second, the relative pros and cons of preliminary sports teacher education in Korea and China were aimed at nurturing competent sports experts with both expertise and personality. They were generally similar in terms of content dimensions; however, they were found to be different in several areas. Particularly in the case of China regarding the teaching subject, practical subjects that were of pragmatic help to the school field were found to be relatively insufficient. Third, the implications for improving China's preliminary PETE were to emphasize the importance of personality in educational goals at the goal level, and as for the content level, it was necessary to replaced them with classes that could be of pragmatic use in the existing teaching method. Furthermore, at the methodological level, professional training of physical education teachers should be proposed, training them to cultivate character. Finally, more positive changes can be pursued if efforts at the environmental level are well-matched and improved.CONCLUSIONS To improve China's preliminary PETE program, it is necessary to enhance the environment and institutions using various teaching methods to cultivate expertise, such as practical aspects of university-field linkage and preliminary teacher personality education.

PURPOSE This study comprehensively compared the perception and interaction of player–coach in the development of mental toughness in soccer.METHODS Data were collected through semi-structured individual interviews from 12 participants (6 athletes and 6 coaches), analyzed using the grounded theory by Strauss and Corbin, and they were compared to the group of athletes and coaches, respectively.RESULTS The following results were obtained: (1) Both athletes and coaches recognized that the experience of coping with the pressure present in competition was a central phenomenon in the development of mental toughness. (2) Regarding the situation and condition that lead to coping with pressure, the athletes emphasized the individual's goal orientation in the context of competitive situations and environmental conditions, while the coaches emphasized the athletic attitude toward competition and development in childhood. (3) The athlete–coach interaction was identified as an intervening condition affecting the experience of coping with pressure. (4) As the action–reaction strategy for the development of mental toughness, the optimistic thinking was emphasized for athlete and achievement-oriented thinking for coach; thus, it differed in the characteristics of mental toughness.CONCLUSIONS This study presented the results of an integrated comparison of mental toughness, which can vary depending on the contextual specificity (soccer) and the subject of perception (athlete– coach), especially indicating the importance of the player–coach interaction, which can contribute to the strategy to be used in mental toughness development.

PURPOSE This study aimed to examine the effect of acute tart cherry juice intake on recovery after intermittent exercise in female field hockey athletes.METHODS Sixteen university female field hockey athletes were studied for a total of 3 days. The cohort was divided into 2 groups, placebo group (n=8, PLA) and the tart cherry juice group (n=8, TCJ), Each supplement was consumed 5 times over 48 hours. On the first day of the study, venous blood was collected before the test, and physical fitness variables (20m sprint, 5-0-5 agility, and Countermovement jump) were performed twice before and after the Yo-Yo Intermediate recovery test 1 to determine the degree of muscle damage and recovery of physical fitness factors. After all tests on Day 1, supplements (PLA, TCJ) were taken. After 24 hours, venous blood collection was performed, and after 48 hours, venous blood collection and physical element variables were measured to verify the effectiveness of tart cherry juice.RESULTS In the TCJ group, a significant effect was found over time in the 5-0-5 ability among the fitness variable items (p<.001) In Countermovement jump (CMJ), there was a significant effect over group and time (p<.001). Second, significant effects over group and time were shown in Interlukin-6 (IL-6) among variable items related to muscle damage and inflammation through venous blood collection (p<.05) and LDH (p<.001), and CK (p<.01) showed a tendency to decrease with time.CONCLUSIONS The results of this study suggest that acute tart cherry juice intake after intermittent exercise tends to reduce muscle damage and inflammation-related variables in female field hockey players, which could help them recover quickly, especially after hectic game schedules.

Second, significant effects over group and time were shown in Interlukin-6 (IL-6) among variable items related to muscle damage and inflammation through venous blood collection (p<.05) and LDH (p<.001), and CK (p<.01) showed a tendency to decrease with time.CONCLUSIONS The results of this study suggest that acute tart cherry juice intake after intermittent exercise tends to reduce muscle damage and inflammation-related variables in female field hockey players, which could help them recover quickly, especially after hectic game schedules.","PeriodicalId":17892,"journal":{"name":"Korean Journal of Sport Science","volume":"97 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75623951","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}

PURPOSE This study aimed to identify the underlying dimensions of brand (professional sport team) authenticity and to develop a valid, reliable scale to measure these dimensions.METHODS A pool of 67 potential items was drawn through a literature review, content analysis, qualitative research (n=43), and an expert evaluation. The identified items were subjected to exploratory factor analysis (n=248) and confirmatory factor analysis (n=285). In addition, multiple regressions were conducted to examine the criterion validity of the scale.RESULTS The results showed that the brand authenticity scale for professional sport teams consists of 42 items representing 8 dimensions: continuity, originality, quality commitment, heritage, symbolism, credibility, stakeholder-related integrity, and consumer-related integrity. The study has proven evidences of internal consistency and convergent, discriminant, and criterion validity of the scale.CONCLUSIONS The findings suggest that the scale developed in this study offers a vital foundation to understand the structure of brand authenticity in the context of sport fans and its impact on sport consumer behavior.

PURPOSE This study investigated the associations between physical fitness and fall efficacy with thigh circumference in elderly women with osteopenia/osteoporosis.METHODS A total of 166 female participants aged 76.3±5.0 years with –1.0≥T-score of femur neck bone mineral density were voluntarily recruited from local community centers. The participants were classified as low 25%, middle 50%, and high 25% groups based on their thigh circumference. Physical fitness measurements, including strength, flexibility, aerobic endurance, and balance were measured with a standardized protocol. The Korean version of the fall efficacy scale (K-FES) was used to assess fall efficacy. Logistic regression analysis was used to estimate odd ratio (OR) of poor physical fitness and low fall efficacy according to thigh circumference levels.RESULTS In terms of physical fitness, the middle 50% group (OR=0.430, 95% CI=0.194-0.953) and high 25% group (OR=0.129, 95% CI=0.049-0.343) had significantly higher linear trend for poor physical fitness compared to the low 25% group (reference), (p<0.001). In fall efficacy, the middle 50% group (OR=0.279, 95% CI=0.119-0.656) and high 25% group (OR=0.100, 95% CI=0.036-0.275) had significantly higher linear trend for low fall efficacy compared to the low 25% group (reference) (p<0.001).CONCLUSIONS The current findings suggest that maintaining high thigh circumference via regular physical activity and diet may contribute to attenuation of decreased risk for poor physical fitness and low fall efficacy in elderly women with osteopenia/osteoporosis.
