Purpose This study is a phenomenological research which tries to describe the subjective experience and to analyze multi-layered meanings, and it finds out the men's training experience and meaning. The purpose of this study is to investigate why the men do Yoga and what the subjective meaning of Yoga experience, and the study examines critically whether Yoga experience especially focused on women is against gender performance and dominant body discourse. Methods For the study, 6 middle & young-old aged men who do Yoga more than 6 months every week are selected as participants. Results The meaning of Yoga for middle & young-old aged men in their lives is as follows. First, it is hard for men to experience Yoga because of social and cultural background. Finding Yoga class which takes men's membership is difficult. Second, middle & young-old aged men's physical feature(interest in their health and disease) and personal background(women friendly daily life) become specific motivation to overcome the barrier to do Yoga. Third, Yoga is 'alterative training', not a training. Yoga is considered as a training which replaces the feature of training called men's sports previously. Fourth, Yoga has a meaning of 'healing' to have our own time. Fifth, Yoga is changed by itself in Yoga culture which is focused on women even though middle & young-old aged men do Yoga for a long time. Sixth, middle & young-old aged men realize that the feature of Yoga is not 'for only women', and they thought it is 'neutral training that men can do too.' Conclusion Consequently, the reason why middle & young-old aged men do Yoga is started from the motivation regarding physical characteristics and personal background, and the main purpose is to cure and to heal our bodies and mind. For them, Yoga means 'alternative training to fit their bodies' and 'their own time'. Moreover, old male adult's training experience and meaning are against gender performance in that it cause a crack in stereotyped gender sports area, but it is notable that there is no intention to resist the dominant gender body discourse.
Purpose The purpose of this study is to investigate the factors for setting proper training duration of frequency that can guarantee the student athletes' right to study and performance, and to derive the ranks of setting proper training duration of frequency of student athletes by school level. Consequently, to provide basic data for the development of training guidelines for the growth period of Korean student athletes. Methods Delphi and Analytic Hierarchical Process(AHP) techniques were used. The Delphi survey was conducted in three phases, and collected data through Delphi survey were computed by SPSS win ver. 22.0 and Excel, using the mean, standard deviation, median, and coefficient of variation. Using the AHP technique, we classified the factors for setting proper training duration of frequency derived through Delphi survey, and calculated the importance by using Microsoft Excel 2010. Conclusion First, elementary students should be guaranteed regular class participation, have basic after school training, and be provided with adequate rest so that they do not lose interest in the exercise. Second, middle school students are required to decide whether to continue exercise based on their ability to exercise and abundant experience. Therefore, when abandoning the exercise, students should be able to faithfully carry out their academic performance. Third, high school students are directly related to college entrance and employment, so they have to concentrate on performance rather than on academic performance.
Purpose This study confirmed the historical significance of the First World War US Combat Strength Training Fitness System for contributing in the ROK military sports development. Methods This research method is literature analysis to be focused by the previous US Army Field Manuals. Results Concretely, The meaning of US Army fitness training was divided into four stages. First, this study confirmed the actual condition of the US Army fitness before First World War. Since 1916, US Army has developed a group physical training program applied the items suitable for the war and has systematically reflected the program in the recruitment training. Second, this study confirmed the process of operating military fitness program during the First World War. US Army physical fitness program provided an effective method to suit soldier fitness for war. Third, this study observed the fitness training changes of US Army after the First World War. At that time, US Army focused on maintaining health and basic physical strength for civilians and reserve forces, but US Army ran parallel with basal physical fitness and combat physical fitness after the Korean War. Fourth, this study compared military strength training between First World War and current US Army. Since First World War, the training of US Army has been developed around doctrine and manuals to be maintained the consistency of the system. In conclusion, US Army physical training system of First World War meant to be provided the basis of current military physical education and physical training. In other words, current fitness training is not dogmatic but has evolved, and it accommodated the basics of soldier physical training course from the past.
Purpose The study was designed to investigate the effects of 12 weeks of circuit training and L-tryptophan supplementation on physical fitness and metabolic syndrome. Methods Forty-one menopausal women were randomly assigned to one of three groups. i.e., combined circuit training and L-tryptophan supplementation group (CT+T: n=14), L-tryptophan supplementation group (T: n=14), and control group (CON: n=13). The subjects in CT+T exercised three sessions per week and took 3g of L-tryptophan per day for 12 weeks. The subjects in T took 3g of L-tryptophan per day for 12 weeks. The subjects in CON were asked to maintain their life pattern for the same period of intervention. Physical fitness and metabolic syndrome-related variables were measured at pre- and post-test. The data were compared by utilizing a repeated two-way ANOVA. Results Main results of the study were as follows: 1) Standing long jump, one leg standing with eyes closed, sit-and-reach, sit-up, and maximal oxygen uptake increased significantly in CT+T. 2) Body weight, body mass index, waist circumference, waist-hip ratio, fat mass, and percent body fat decreased significantly in CT+T. 3) Total cholesterol decreased significantly in CT+T. 4) Fasting plasma glucose (FPG), fasting plasma insulin, and HOMA-IR decreased significantly in CT+T. FPG and HOMA-IR decreased significantly in T. 5) Systolic blood pressure, diastolic blood pressure (DBP), mean arterial pressure (MAP), and rate pressure product decreased significantly in CT+T. DBP and MAP decreased significantly in T. 6) Number of metabolic syndrome risk factors decreased significantly in CT+T and T. Conclusion It was concluded that the circuit training and L-tryptophan supplementation would have positive effects on physical fitness and metabolic syndrome, and that L-Tryptophan supplementation would have positive effects on metabolic syndrome by improving insulin resistance and hypertension in menopausal women.
PURPOSE The purpose of this study was to develop a non-face-to-face self-regulation training program for middle and high school student-athletes through the conduct of a group online video counseling session, as well as to verify the effectiveness of such a tool. METHODS Based on the models of Zimmerman(2000) and Han Si-wan (2008), the 12-session non-face-to-face self-regulation training program consisting of interactions involving cognitive, emotional, and behavioral factors was developed and used on a 16-member experimental group. Additionally, self-regulation and mental toughness questionnaires were given to each member before and after the program, and the results were compared with the results of a 17-member control group. Since a qualitative evaluation was conducted, recorded training contents were organized into a text file; after which, a step-by-step coding procedure was performed, and then meanings and themes were identified and categorized. RESULTS Quantitative analysis found that the volitional inhibition mode of the control group decreased significantly; this was in comparison to the increase in the self-regulation mode of the experimental group. In addition, among the seven sub-factors of the mental strength test of the experimental group, a significant increase was found in the post-test of self-belief, attention control, emotional regulation, resilience, and optimism factors. As a result of qualitative data analysis, they complained of difficulties in the early stages of participation, but gradually recognized their problems and searched for changes, showed changes in cognition, emotion, and behavior as they approached the end of the study period. CONCLUSIONS It can be said that the non-face-to-face self-regulation training program helped student athletes improve their school life and performance by driving positive cognitive, emotional, and behavioral changes.
The purpose of this study was to investigate the effect of wearing of safeguard devices on various blood ions (i.e., Na+, K+, Ca2+) concentrations, gas parameters (PO2, PCO2, hematocrit [Hct], hemoglobin [Hb], Saturated [Sat] O2), and energy substrates (i.e., glucose, free fatty acid [FFA], lactate) concentrations during Kumdo training. Research scope extended to examine the heart rate changes during each exercise sessions. In order to achieve the research goal, 10 male elite Kumdo players, who play for G city in Gyeongsangbuk-do, were participated, and their mean maximum oxygen uptake level was 51.2(±6.1)mL· kg-1min-1. All subjects undertook Kumdo training sessions twice, which carefully pre-planned and consisted of routinely carrying out exercise program. Training period for each session was 80 min long including 10 min each for warm-up and warm-down period, but the conditions with wearing body protection devices were different following either with wearing complete set of safeguard devices or without wearing any safeguard devices except general training cloth. Heart rate was measured by every minute interval. K+ and Ca2+ showed interaction effect between the conditions with wearing safeguard devices and conditions with time of Kumdo training. Hct and Hb level significantly increased after 60 min Kumdo exercise regardless of wearing safeguard devices. Kumdo training induced dropping of blood pH independently with wearing safeguard device conditions, however the values and/or concentrations of PO2, Na+, glucose, lactate, Sat O2were significantly increased. Heart rate was maintained marginally higher values throughout exercise period when safeguard devices were worn. Based on these results, it was concluded that wearing the safeguard devices could possibly be causing a physiological metabolic changes, and this may be drawn by increased body fluid loss and energy expenditure. Further study should be undertaken to examine the effects of wearing safeguard devices on hitting intensity and hormone secretion and concentrations, that closely associated with body fluid and ion balance during Kumdo exercise and/or training.
Purpose The purpose of this study was to investigate the effect of a 10-week aerobic exercise training on cardiovascular function, atherosclerosis, and vascular endothelial function in elderly women. Methods Twenty impaired fasting glucose (IFG) and normoglycemic elderly women volunteered to participate in the study. The participants in aerobic exercise training group (TR: n=9) completed 20-40 minutes of aerobic exercise program at 30-50% HRR for 3 times per week during 10 weeks. The participants in control group (CON: n=11) were asked to maintain their normal life pattern during the same intervention period. Results Main results of the study were as follows: 1) There were no significant main effect or interaction in body weight, fat-free mass, fat mass, percent body fat, and body mass index. 2) There were no significant main effect or interaction in heart rate, stroke volume, cardiac output, total peripheral resistance (TPR), systolic blood pressure, diastolic blood pressure, mean arterial blood pressure, pulse pressure, and rate pressure product. However, interaction between group and test in TPR was close to statistically significant level (P =.054), and it tended to be decreased in TR group. 3) There was a significant main effect of test in high sensitivity C-reactive protein(hs-CRP), it tended to be decreased in TR group. There were no significant changes in total cholesterol(TC)/high density lipoprotein-cholesterol (HDL-C) ratio, triglyceride/HDL-C ratio, and low density lipoprotein-cholesterol/HDL-C ratio. 4) There were significant main effect of group, main effect of test, as well as interaction between group and test in % flow mediated dilation(FMD), and it increased significantly (P<.01) in TR group. Nitric oxide tended to be increased in TR group, even though it did not change significantly in both groups. Conclusions It was concluded that the 10-week aerobic exercise training would be beneficial for improvement of vascular endothelial function, resulting from the decrement of total peripheral resistance.
Purpose This study was designed to examine the effects of 8 weeks of circuit exercise training on blood lipids, insulin resistance, cardiovascular function, and metabolic syndrome risk factors in 40~50s male bus drivers. Methods Twenty-nine bus drivers were randomly assigned to one of two groups, i.e., circuit exercise training group (TR: n=14) and control group (CON: n=15). Subjects in TR participated in circuit exercise training 30-40 min per session, three sessions per week for 8 weeks, whereas subjects in CON were asked to maintain their normal life pattern for same intervention period. The variables regarding body composition, blood lipids, insulin resistance, cardiovascular function, and number of metabolic syndrome risk factors were measured and compared between two groups as well as between pre- and post-test. Data were analyzed using repeated two-way ANOVA with post hoc test. Results Main results of the present study were as follows: 1) Waist circumference, waist-hip ratio, body mass index, and percent body fat decreased significantly in TR. 2) LDL-C decreased and HDL-C increased significantly in TR. 3) Fasting plasma insulin and HOMA-IR decreased significantly in TR. 4) Regarding cardiovascular function, diastolic blood pressure and mean arterial pressure decreased significantly in both TR and CON. hs-CRP were not changed significantly; however, it tended to be decreased TR. 5) Number of metabolic syndrome risk factors decreased significantly in TR(2.86±0.86 to 1.50±0.76). Conclusions It was concluded that 8 weeks of circuit exercise training would be beneficial for improvement of blood lipid profiles and insulin resistance, resulting in preventing metabolic syndrome. In particular, it would be very clinically meaningful that number of metabolic syndrome risk factors decreased from 2.86±0.86 to 1.50±0.76 by the circuit exercise training.
The purpose of this study was to verify the effect on elementary school students in the exercise start stage by performing a sport psychological skill training to improvement of psychological skill and life skill. Participants were eight elementary school boys volleyball player. The program consisted of psychological skills and life skills in educational counseling model of Visek et al(2009). It was conducted 40-50 minutes a session in total for 22 sessions. Data was collected through a psychological test, worksheet and participant observation, in-depth interviews. The collected data was analyzed to verify difference by paird t-test after pre-middle-post test and to extract meaningful data category. Quantity analysis showed that a result of sport psychological skill test proved a significant difference in willingness to overcome, confidence, concentration, anxiety regulation. Life skill test were no significant differences in all factors. However, the rise of scores was observed on result of the pre-middle paired t-test of life skill during season. Quality analysis showed possibility of goal setting, concentration on the routine, decrease of competitive anxiety, increase of positive thinking, self-understanding and understanding of others, promotion of communication among team members. This sport psychology skill training had a significant effect on the psychological skills of elementary players change. But it seems to be necessary life skills in a more through review of the information.
Purpose The aim of this study was to provide athletes and coaches on informations and benefits of a taper through evidence-based scientific studies and literatures in order to optimize an athlete’s top performance for the major competition. Methods Studies and literatures search was conducted using the databases RISS, KISS, SPORTDiscuss. Key words searched: taper AND(competition, OR performance, OR training, OR training). This study were eventually cited by 22 articles for results of this in total 100 articles. Results The training load is remarkably reduced during a taper. With a reduced training load, training intensity should be maintained during the taper. The training load reductions during the taper should be programmed with reducing training volume at 41% to 60% of pretaper training. The reduction of training frequency during a taper means that affect moderately trained athletes and highly trained subjects differently, reducing 30% to 50% of pretaper training and maintaining training frequencies, respectively. Detraining the duration of a taper is not easy. Most athletes is beneficial from a 2-week shorter or longer tapers, depending on their individual profiles of fitness loss, fatigue dissipation, and anxiety. The manipulations of this training program variables usually affect for most athletes and maximal performance gains. Conclusion Training intensity should be maintained during the taper, training volume reductions should be programmed at 41% to 60% of pretaper training. The reduction of training frequency could be reduced 30% to 50% of pretaper training, and most athletes is beneficial from a 2-week shorter or longer tapers. Future researches should be conducted the practical & effectual differences in individual and teamed-based sports after a taper procedure.
