Purpose This study focused on analyzing the policies regarding operation of Sportstoto, a sole legal sports betting business in Korea. Methods In order to fulfill the research goal, literature review on reports, articles, and statistics from Ministry of Culture, Sports and Tourism, National Gambling Control Commission, Korean Sports Promotion Foundation, and other precedent studies was conducted. Results Currently Sportstoto fails to maintain its competitiveness due to inconvenient betting process, lack of product diversification, and low payout rate, resulting in the growth of illegal sports gambling. In addition, governmental aid for sports budget has diminished consistently, while at the same time the revenue cap regulation for betting industry restrains the development of Sportstoto and disturbs the gathering of sports budget, which appears to be a policy contradiction. Moreover, there are no specific guidelines for the expenditure of Sportstoto revenue which function as a budget. Conclusions This study suggests three ideas to overcome these problems. First is the alleviation of regulation in non-monetary area so that Sportstoto can improve its competitiveness against illegal sports gambling. Second is the clear establishment of policy regarding sports budget, either to foster Sportstoto as a fundraising business, or to enlarge governmental allocation for the budget. Lastly, institutional management must be provided for the expenditure of Sportstoto revenue as to follow government’s sports policies.
Purpose The purpose of this study is to investigate the alienation and the overcoming process of the physical activity participation of people with Adventitious Visual Impairment(AVI) Methods 21 Adults with AVI were recruited and one on one semi-structured interview was conducted. Ground theory was used to analyze the data. Member check, peer debriefing was conducted to enhance the trustworthiness of this study. Results As a result, a total of 203 concepts were derived. This consisted of 21 subcategories and the common themes of the subcategories were categorized into nine categories. Specific results are as follows. First, the physical activity of people with AVI was directly affected by the sports facilities, physical activity programs, and professional instructor. This causal condition resulted in the loss of leisure experience in the context of the busy daily life and the depressed psychological state. Second, due to the perceived need of health care and the positive involvement of others, people with AVI came to expect the effect of exercise. Third, people with AVI participated in physical activity again as a tool to achieve the purpose of health improvement. This type of physical activity has a limitation that it can not guarantee the continuity of physical activity due to the limitation that it does not contain autonomy and interest of people with AVI. Conclusions Based on these results, the following suggestions were made. First, it is necessary to improve the environment for ensuring participation in physical activity of people with AVI. Moreover education and promotion of the effects and values of the exercise should be carried out for people with AVI and their guardians. Second, it is necessary to diversify physical activity types and reconstruct existing exercise programs.
The purpose of this study was to critically interpret a certain sports-related idea, "Integrated Korean Team," which was an issue at the PyeongChang Winter Olympics. The idea emerges as a specific political agenda under the conditions of domestic politics and the special environment of Korean national affairs and discourse. To this end, we investigated media texts on the relationship between sports, political dynamics and views on related discourse that were produced in 1990-1991 and 2018. The main findings are as follows: First, sports functions as a political socialization tool for political power as it forms public opinion. Second, sports exchanges work as a kind of international politics. Specifically, political power controls sports as certain political situations arise and political elites' needs change. Third, mega sports events have tended to become politicized in recent years as they become more effective. Fourth, North Korea’s sports under political power cannot be easily dealt with by the private sector, and it has limitations because it is not politically independent. The analysis showed that the negotiation process and realization of the Integrated North and South Korean Team seemed to be a turning point in politics and sports. Here are the conclusions drawn from discussing the two unifying events in 1991 and the situation in 2018. First, both South and North Korea pulled the Integrated Korean Team card when political needs arose. Second, when the two Koreas did not need to reconcile due to changes in the political situation between the two Koreas, they did not want to make efforts to integrate Korean Team. Third, the position of the political elite was directly represented by the position of the South-North Korean team. Fourth, the supporting public opinions of the Integrated Korean Team are gradually diminishing as the power gap between the two Koreas widens and sports players' human rights issues emerge.
Purpose The purpose of this study is to investigate the effectiveness of the holistic focus of attention(H-FOA), presented as an alternative attention concept, to explore effective attention focus for the skilled performer. Methods KPGA's experts (N = 24) were selected and randomly assigned to external focus, overall focus and control groups. Experiments were conducted in the putting competition of the target distance (4m, 5m and 6m). Performance was measured for accuracy. Results Interestingly, the control group showed the high putting performance accuracy (MRE). In addition, the holistic focus of attention group was able to identify performance similar to the control group. The effect of external attention focus could not be confirmed. Conclusions Results of this study indicate that external focus may be unnecessary for skilled golfers. Rather, holistic focus of attention is highlighted for the improvement of players’ attentional focus under pressure.
Purpose Student-athletes in Korea are confronted with career development in both academics and sport. This paradigm change in sport policy aims at guarantee of student-athletes' learning rights and successful career transition after sport. But dual career development can be a difficult task for student-athletes, if there is a lack of social support. The purpose of this study was to provide updated information regarding the burnout-in-sport literature and suggest directions for future research in sport psychology. Methods This study is based on reviewing the literature. In order to improve the validity of discussion, the author focused on the findings of the published research articles targeting student-athletes. The outcomes were examined and discussed based on models and measurement tools of athletes’ burnout. Results First, longitudinal study is needed to understand causalities in sport burnout. Second, it is necessary to develop korean sport burnout scale reflecting our social and cultural contexts. To do this, qualitative research should be preceded to provide in-depth understanding on burnout phenomenon of student-athletes. Third, the cut-off values which can allow the separation between clinical and nonclinical athletes should be developed. Fourth, due to dual career development as a new sport environment, burnout research has to pay attention both psychological variables in person and environmental variables. Conclusions Since the 1990s burnout research in sport psychology has been increased in its quantity as one of the remarkable topics in Korea. Based on the comprehensive and systematic review of the literature, directions for future research are suggested.
Purpose The purpose of this study was to investigate the effect of vibration therapy on the functional, imaging, and mechanical properties in elbow flexor after a single bout eccentric exercise. Methods Twenty-three untrained adults male participated in this study [CON(control)= 11, VT(vibration)= 12]. Volunteers performed 5-set of 6 maximal (90˚/s) eccentric contractions of the non-dominant elbow flexor on a isokinetic dynamometer. Vibration was applied using a side alternating vibratory platform (12 Hz frequency, 4 mm amplitude) with 3-set of 60 sec during 3-day after eccentric exercise. Results The VT group showed a reduction in exercised-induced muscle damage(EIMD) symptoms in the form of attenuating muscle swelling and echo intensity (P<.05) compared with the CON, mechanical properties were improvement (P<.05) compared with the CON. However, muscle soreness, range of motion and maximal voluntary isometric contraction were not significant (P<.05). Conclusion As currently practiced, vibration therapy after eccentric exercise may reduce EIMD by improving quality of the muscle, suggesting that this therapy is an effective strategy for EIMD.
Purpose This study was designed to investigate the effects of weight-bearing exercise and CareRing treatment on cardiovascular responses, popliteal vein functions, and vascular elasticity of 30-40s women who had worked longer than eight hours a day in a standing position. Methods Thirteen subjects participated in 30 min of standing up treatment (STAND), weight-bearing exercise treatment (EX), and weight-bearing exercise with CareRing treatment (EX+RING). Each subject took part in the three trials repeatedly in a counter-balanced order and proceeded with a wash-out period of at least one week between the respective trials. Results The main results were as follows: 1) Significant reduction in EDV, no change in the diameter of popliteal vein, trend of reduction in blood flow of popliteal vein, and increased baPWV, indicating reduction of vascular elasticity of whole body, were shown in the STAND. 2) CO and EF increased significantly, and TPR decreased significantly in the EX. Blood flow velocity and blood flow volume of popliteal vein increased significantly, and baPWV decreased significantly from immediately after the treatment throughout the recovery phase in the EX. 3) HR, CO, and EF increased significantly in the EX+RING. Blood flow velocity and blood flow volume increased significantly in the EX+RING. Diameter of popliteal vein increased significantly immediately after the treatment and decreased significantly at 40 minutes of recovery. TPR and baPWV decreased significantly immediately after treatment compared to the STAND. Conclusions It was concluded that weight-bearing exercises would be effective in preventing venous or cardiovascular diseases occurred due to long-standing in 30-40s women, who are at high risk for such diseases. Furthermore, it would be more effective to combine pressure treatment with CareRing during weight-bearing exercises.
Purpose The purpose of this study was to investigate changes of the cardiovascular system by comparing heart rate (HR) and blood responses to exercise in younger and older adult dogs and to verify the value of dogs as aging model in exercise science research. Methods A total of 11 healthy beagles were divided into 2 groups according to age: younger adult dogs (1~2 years old, 7 animals) and older adult dogs (9~11 years old, 4 animals). Each animal exercised on the treadmill for 25 minutes, twice a week, and for 4 weeks. The exercise intensity was gradually increased by applying four different protocols. Resting HR, HR during exercise, and HR recovery time were determined as HR parameters. Biochemical analysis was performed on blood samples. The independent Student’s t-test and one-way ANOVA were used to analyze the mean difference of each variable. The associations between age and HR parameters were determined using Spearman‘s analysis. Results Older adult dogs showed higher HRs during rest and exercise than younger adult dogs. HR recovery time was significantly longer in older adult dogs than in younger adult dogs. A strong positive relationship was observed between beagles’ age and resting HR, HR during exercise, and HR recovery time, respectively. The heart rate response to the treadmill exercise was similar between the 1st week and 4th week in younger and older adult dogs. Exercise significantly reduced the white blood cell level in older adult dogs and increased the alkali phosphatase level in younger adult dogs. Conclusions The results of this study demonstrated that short-term treadmill exercise may have a positive effect on the aerobic capacity, inflammation, and bone formation, suggesting that dogs are valuable as aging model in exercise science research.
Purpose The purpose of this study was to investigate the effect of treadmill exercise and MitoQ treatment on NADPH oxidase, antioxidation and vascular function-related factors in aortic of D-galactose-induced aging rats. Methods To induce the animal model of aging, D-galactose was diluted in saline, and a dose of 100mg /kg was intraperitoneally injected into Sprague-Dawley rats once a day for a total of 10 weeks. Rats were divided into five groups: Control group (CON, n=9), D-galactose control group (DC, n=9), D-galactose+MitoQ group (DM, n=9), D-galactose+Exercise group (DE, n=9), D-galactose+MitoQ + Exercise group(DME, n=9), and treadmill exercise was conducted for 5 days/week during 8 weeks with gradual increase of intensity. MitoQ treatment was intraperitoneally injected at a concentration of 100μM/kg twice a week for 8 weeks during the research period. Results The result showed that treadmill exercise and MitoQ treatment decreased the expression of NADPH oxidase level and increased antioxidant enzyme such as SOD-2, catalase. It lead to positive effects such as increasing the level of eNOS, a protein involved in vascular function while decreasing the level of VCAM-1. In addition, as a result, it showed the structurally reduced intima-media thickness. Conclusions It can be concluded that treadmill exercise and MitoQ treatment are effective in ameliorating and treating vascular dysfunction resulting from aging.
Purpose The purpose of this study was to verify their effectiveness as we develop and apply worksheets for improving life skills and resilience of collegiate Taekwondo athletes. Methods The study went through three stages: developing, applying, and evaluating. In the developing stage, literature review, expert meeting, and pilot test (n=25) were conducted to develop the worksheets. In the applying stage, 37 athletes participated in life skills program using the worksheets. Data were collected by survey and in-depth interview. In the evaluating stage, paired t-test, word cloud analysis, and inductive content analysis used to identify the effect of worksheets. Results First, the worksheets were composed of 3 stages (plan, acquisition, implementation) and 15 sessions including 12 factors of life skills. Second, the worksheets were applied in each phases such as planning, acquiring, and implementing. In the planning phase, they understood life skills knowledge and set goals. In the acquisition phase, students learned specific life skills’ strategies. In the practice phase, the acquired life skills were applied and practiced in real life and relationships. Third, the result of paired t-test showed that all the factors of life skills and 6 factors of resilience were significantly improved. In addition, word cloud and in-depth interviews revealed that the participants' cognitive and psychological changes were most prominent. Conclusions The life skills worksheets consists of 12 factors in 15 sessions and can be considered as an effective intervention tool for improving the resilience and life skills of collegiate Taekwondo athletes.
