Purpose This study seeks to explore the process where drop-out elite athletes collect their life skills obtained during their sports career and transfer them to their daily lives. Methods An open-ended questionnaire survey was conducted on a total of ninety retired elite athletes and the responses were analyzed. Based on the results of inductive analysis, five subjects were selected for a follow-up in-depth interview. The responses to the open-ended questionnaire were analyzed by the inductive content analysis method and the results from in-depth interviews by the deductive content analysis method. Results A total of 478 life skills were collected from the drop-out elite athletes and structuralized into four general categories: psychological skill, social skill, self-management skill, and goal-setting skill. The results of this study have revealed that life skills positively transferred to their future courses of lives and daily lives. Conclusion It is believed that the results of this study will be helpful to understanding the concept of sports life skills, studying the possibility of transfer, and provide the basic data for helping drop-out elite athletes with re-socialization and positive adaptation.
Purpose The purpose of the study was to investigate the effect of vibratory stimulus on the static postural control of 8 healty senior adults. Methods To achieve this goal, all subjects participated in two different kinds of static postural control tasks. Task 1 was a static postural control task, where both-legs stand on the ground. Second task was an unstable static postural control task using only single leg stance. As they maintain their balance, 6 different vibratory stimulus were provided on the sole of their feet(personal threshold 0%, 80%, 90%, 100%, 110%, 120%). Results The results of the study were as follows: First, there was no significant differences in postural control ability according to different types of vibrator intensity. Second, there was a significant difference in single-leg postural control ability according to vibrator intensity. Third, there was a significant difference in anterio-posterior stability according to the different types of vibrator intensity. Conclusion Stochastic resonance using vibratory stimulus was more effective in the single leg stance task, rather than the double leg stance task. Moreover, sub-threshold vibratory stimulus(80%, 90%) intensity were more effective than higher vibratory stimulus(100%, 110%, 120%).
Purpose This research was to empirically analyze the relationship between a commercial sports center customer-perceived employees' emotion labor (deep acting, surface acting) and sports center emotion, service quality & relationship retention through structural equation model analysis. Methods For this purpose, this study set 270 members at the two commercial sports centers(facilities equipped with more than 3 events) located in Suwon as the research subjects. In an effort to verify the proposed structural model, this study used SPSSWIN Ver. 21.0 and AMOS 18.0. Results first, this study found that deep acting had a positive effect on positive emotion. Second, it was found that surface acting had a positive effect on negative emotion. Third, deep acting was found to have a positive effect on service quality. Fourth, surface acting was found to have a negative effect on service quality. Fifth, the results showed that positive emotion didn't have a positive effect on relationship retention. Sixth, negative emotion was found to have a negative effect on relationship retention. Seventh, service quality was found to have a positive effect on relationship retention. Conclusion This findings indicate that the management of emotional labor is critical from the aspects of personnel management in sport centers.
The purpose of this study was to determine how acute active pc-video game affects kinematic variables and muscle activities of adolescents. Fourteen middle school students(age: 15.9±0.7 yrs, height: 171.3±6.1cm, weight: 60.0±5.4 kg, right handed) who have no musculoskeletal disorder were recruited as the subject according to having experience in using the pc-video game for more than six months. Maximum angle, angular velocity, and muscle activity of the upper extremity were determined for each trial. For each dependent variable, a paired t-test was performed to test if significant difference existed between pre- and post a 60 minute active pc-video game(p<.05). This study found that one hour pc-video game hour may not affect on movement and ROM of the finger and the wrist, whereas it may have an effect on muscle activity of the upper extremity. It seems that repetitive movement pattern during an active pc-video game may hinder muscle activity of adolescents’ upper extremity. Part of the increase in musculoskeletal disorders is linked to the amount of time adolescents are allowed to play video games. This study found that an active pc-video game appears to have negative effects on the upper extremity muscles. Since wrist movements are continually repeated throughout the video game, carpal tunnel syndrome may possibly be caused by long-term exposure to video games.
The purpose of this study was to explore and confirm Kumi-kata related factors of muscle strength by performance level in Korea elite female judoists. In order to achieve this purpose, 14 elite female judoists participated to this study. The subjects were divided to two groups (World Class Group and Non-World Class Group) according to their world ranking level(by ranked 30th). The analysis factors were repeated grip strength, Kumi-kata specific pulling strength and isokinetic strength of trunk joint. The results were as follows: Firstly, World Class Group had significantly higher repeated grip strength as compared to non-world class group (p<.001). Secondly, World Class Group had significantly higher specific Kumi-kata pulling strength as compare to non-world class group (p<.05). Finally, The differences between the two groups for isokinetic strength of trunk joint were non-significant. The results of this study indicates that a strong relationship exist between Kumi-kata related specific muscle strength and performance level in korea elite female judoists.
The purpose of this study was to examine whether β-alanine ingestion for 8 weeks can regulate isokinetic knee strength, and 3km record in middle-long distance woman cyclists. Fourteen middle-long woman cyclists participated in this study and were divided into two groups; training group with beta-alanine ingestion and training group with placebo ingestion. All subjects took in beta-alanine or placebo supplement three times per a day for 8 weeks. Physical activity was evaluated by measuring the isokinetic muscular strength and 3km record before and after intervention for 8 weeks. As a results, in isokinetic test, there were significant interrelationships in peak torque of the right and left flexors at 60°/sec, peak torque of the right and left extensors at 180°/sec, peak torque of the right flexors at 180°/sec. In 3km record, result showed a significant interrelationship by groups and time. The results of present study provide evidence that beta-alanine supplement may be effective to increase physical activity and competition record in middle-long woman cyclists.
The purpose of this study was to examine whether the difference between ingestion of nutrition supplements for 8 weeks can regulate physical activities and fatigue recovery. Fifty one middle-aged women participated in this study and were divided into placebo, ingestion of 20g energy supplement and ingestion of 40g energy supplement groups. Energy supplement mainly consists of carbohydrates and proteins. All subjects take in this supplement one time per a day for 8 weeks. Physical activity and fatigue recovery were measured before and after ingestion of energy supplement for 8 weeks by using the Wingate anaerobic and a blood tests. In the Wingate anaerobic test, the peak power(p<.01) and average power(p<.05) were significantly increased in ingestion of 20 and 40g supplement groups compared to the placebo group. Although concentrations of lactate and growth hormone in the blood didn’t show a significant differences among groups, blood concentrations of cortisol and ammonia were further enhanced in ingestion of 20 and 40g supplement groups compared to the placebo group(p<.001). The results of present study provide evidence that energy supplement mixed with carbohydrates and proteins may be effective to increase physical activity as well as to reduce blood concentration of fatigue-related factors after exercise.
The primary purpose of the study was to compare cardiovascular function, mental health indices, stress-related variables according to body mass index (BMI) and percent body fat (%BF) in 20s females. Sixty-eight women, aged 20-29 yrs, participated in the study as subjects. There were three groups, i.e., normal group (BMI<24 kg·m-2 and %BF<25%; n=25), normal weight obese group (BMI<24 kg·m-2 and 28%<%BF<40%; n=19), and obese group (BMI>26 kg·m-2 and 28%<%BF<40%; n=24). Cardiovascular function, mental health indices, stress-related blood variables were measured and compared among three groups. Main results of the present study were as follows: 1) SBP, DBP, mean arterial pressure, and RPP were significantly higher in obese group than normal group. 2) There were no significant differences in mental health indices among three groups. 3) Fasting plasma insulin, fasting plasma glucose, and CRP were significantly higher in obese group than normal weight obese group and normal group. It was concluded that there would be abnormal cardiovascular function, insulin resistance, and inflammation in general obese individuals in 20s females, not normal weight obese and normal individuals.
The purpose of this study was to find out what experiences pre-service physical education teachers have before, during and after student teaching along with teacher educational meanings in the experiences. The subjects of this study were 7 senior students in department of physical education of B university located in A city. The data were collected through daily records of student teaching and in-depth interview(group and individual). The collected data were analyzed using the methods of Smith & Kinsella(2009) and Spradley(1980). The analysis showed expectation for learning(knowledge, skills, behavior) and realization(feeling, stimulation, awareness) before student teaching, fight and compromise with 'me'(body, spirit, life), 'you'(teacher, student) and 'it'(instruction, environment, episode) during student teaching, and regret of 'instruction'(plan, execution, evaluation), 'relationship'(forming, maintaining, improving) and 'role'(teacher, attitude, sense of calling) after student teaching. These characteristics were discussed in 4 aspects of educational meanings including seeking essence, seeking forms, seeking roles and seeking status. Lastly, the study suggested unification of student teaching contents, introduction of exclusive teacher system for student teaching, establishment of evaluation system for student teaching program and development of field ability strengthening program available to connect with student teaching in physical education.
The purpose of this study is to analyse that the college students' recognition on abuse scene of sport broadcasting influences verbal violence. The subjects were college students in P municipality and this study distributed 230 questionnaires among them. And 203 questionnaires were collected except some questionnaires that didn't fill in them properly. To analyze them, this study used SPSS Win 20.0 and AMOS 20.0 and came to a conclusion as follows. First, the College students' negative recognition on abuse scene of sport broadcasting had negative influences on verbal violence. Second, home environment wasn't affected by the college students' negative recognition on abuse scene of sport broadcasting. Third, the verbal violence also wasn't much effected by the home environment of the college students. Finally, the home environment didn't intervene in the relationship between the college students' recognition on abuse scene of sport broadcasting and the verbal violence. Therefore this study considers that the abuse scene in the game on the live broadcasting needs to apply sanction properly by a broadcasting station for TV viewers, although the college students with a higher negative understanding of this abuse scene use less verbal violence.
