  • The purpose of this study was to investigated the effect of taping intervention applied to the diaphragm on the anaerobic performance in 30 seconds. 18 healthy college students were randomly divided into experimental group(KT=9) and control group(Sham=9). In both groups, pre and post measurement was performed by wingate test, and post measurement was performed with taping application after a week rest. The statistics between two groups on the rate of change pre and post were analyzed through Mann-Whitney U test. Statistically, it showed that only the average power(AP) of control group was significantly different. This means that diaphragmatic taping did not affect the performance of anaerobic exercise for 30 seconds. However, considering the increase in aerobic metabolism during long-term anaerobic exercise longer than 30 seconds, further studies on anaerobic exercise performance within various time ranges are needed.

  • This study investigated the effect of exercise training and garlic powder ingestion on blood lipids and antioxidants activity in rats. Twenty-eight male Sprague Dawley rats were fed a high-fat diet with or without garlic powder (500 mg/kg) for four weeks as grouped in control (CON), exercise (EXE), garlic (GAR), and garlic + exercise training (GAREXE), respectively. EXE and GAREXE were trained on the treadmill for the same periods. Weight of fats (mesentery, perirenal, and epididymal) were weighed and blood glucose, triglycerides (TG), total cholesterol (TC), and high density lipoprotein- cholesterol (HDL-C) were analyzed and low density lipoprotein-cholesterol (LDL-C) was calculated. Malondialdehyde (MDA) and superoxide dismutase (SOD) for lipid peroxidation were analyzed in liver tissue. Body weight in GAREXE was significantly lower in the statistics than that in other groups (p<0.05), and the volume of fat in GAR and GAREXE was also much lower (p<0.05). Blood glucose was significantly lower in EXE and GAR (p<0.05), however, there was no effect of exercise training. Blood TG was lower in GAR and GAREXE (p<0.05), however, there was no effect of exercise training. HDL-C was significantly improved in EXE and GAR compared to CON (p<0.05), and GAREXE was higher than EXE (p<0.05). MDA content was considerably lower in GAREXE compared to EXE (p<0.05), and SOD activity was much higher in other groups compared to CON (p<0.05). In addition, GAREXE was significantly higher than EXE and GAR, thus there was significant increase when a garlic diet was carried out together with exercise (p<0.05). These results suggested that garlic powder ingestion during the training periods had a beneficial effect of lowering glucose and enhancing blood lipids profiles. Moreover, it also has antioxidant effects, which means that it could possibly suppress aging. It is necessary to inspect various effects of garlic with a variety of research methods regarding sampling process, production process, intake method, etc.

  • Purpose: This study was to examine the effects of an exercise program on physical fitness, cardiopulmonary function and life satisfaction for adult women. Method: The exercise program combined dance and resistance training. The subject group consisted of 114 women aged between 33 and 60. Three 8-week sessions consisted of 55-80% HR max for 60-90 minutes a day and 3 times a week from March to November, 2004. Data were collected through pre- and post-exercise tests before and after each session. Data were collected with dynamometer, sphygmomamometer, spirometer and structured questionnaires. Data were analyzed employing descriptive statistics and paired t-test with SPSS/PC(10.0version) program. Results: There were significantly positive changes in muscle strength, flexibility, balance quality, forced vital capacity and life satisfaction, but no significantly positive changes in agility and blood pressure. Conclusion: This study showed that an exercise program has partially positive effects for adult women. The results of this study suggest that there should be programs of continuous exercise at community health centers for adult women's health.

  • The explosive growth rates in sales of climbing clothes-centered outdoor wear has slowed; however, athleisure wear worn while enjoying sports activities is still popular. This research study investigated differences between pursuing benefits of athleisure clothing and purchase intentions of athleisure clothing according to lifestyles, targeting male and female consumers aged 20s-50s. Analytic research data was statistically processed with the use of SPSS 18.0. The factor analysis and reliability analysis, multiple-regression analysis and t-test analysis and descriptive statistics were conducted. The study analyzed the results of pursuing benefits of athleisure clothing according to lifestyle. The study results showed that fashion oriented, health oriented, and sociability oriented factors had significant effects on youth and fashion; however, rational consumption, leisure orientation, sociability orientation, and value oriented factors showed significant effects on everyday clothing functionality. Health orientation and leisure orientation factors also exerted significant effects on comfort; in addition, the factors of fashion oriented, value oriented, rational consumption, and health orientation also had significant effects on ideal body image. This study investigated purchase intentions for athleisure clothing according to lifestyles. The study results revealed that fashion oriented, leisure oriented, private life centered, and health oriented factors also showed significant effects on purchase intentions for athleisure clothing.

  • The team's performances were analyzed by evaluating the scores gained by their offense and the scores allowed by their defense. To evaluate the team's attacking and defending abilities, we also considered the factors that contributed the team's gained points or the opposing team's gained points? In order to analyze the outcome of the games, three prediction models were used such as decision trees, logistic regression, and discriminant analysis. As a result, the factors associated with the defense showed a decisive influence in determining the game results. We analyzed the offense and defense by using the response variable. This showed that the major factors predicting the offense were non-stop pass and attack speed and the major factor predicting the defense were the distance between right and left players and the distance between front line attackers and rearmost defenders during the game.

  • Performance indicators have often investigated and developed in order to identify foundational elements and factors for an enhancement of performance in sports. In order to identify the valid performance indicators it is important that the indicators used within a performance analysis system discriminate between the winning and losing performances within a match (Hughes and Bartlett, 2002). However, the performance indicators proposed in research studies on basketball performance have not been used for real-time analysis and feedback within a coaching context. Such real-time support for the coach and players has been described within research on other sports (Choi et al., 2004; O'Donoghue, 2001; Palmer et al., 1997). Within the process of real-time feedback, the identification of relevant performance indicators that distinguish winning and losing performances should be the first stage of the development of a real-time analysis system. Therefore, this study investigated the differences between winning and losing teams in terms of a set of performance indicators gathered during the analysis of 10 English National Basketball League matches. Winning and losing teams were compared using whole match data (N=10) as well as individual quarters (N=40). A series of Wilcoxon Signed Ranks tests was used to identify the relevant performance indicators that discriminate between winning and losing performers within whole matches and individual quarters. The tests found that 3 point shots made (p<0.05) and Assists (p<0.05) were significantly different between winning and losing teams within matches. However, 2 point shots made (p<0.05), 2 point shots attempted (P<0.05), percentages of 2 point shots scored (p<0.05), 3 point shots made (p<0.05), Defensive Rebounds (p<0.05) and Assists (p<0.05) were significantly different between winning and losing performance within quarters. The analysis task should be based on relevant performance indicators which explain the current performances to performance analysts and coaches. Within a real-time analysis and feedback scenario, this will have the additional benefit of supporting a decision based on immediate performance within the most recent quarter. Consequently, the real-time analysis system would use performance indicators which have the property of construct validity to support the decisions of the coach.
