[Purpose] The purpose of this study was to examine the effect of recovery methods comparing with change ratio in Lactic acid(LA), Heart rate(HR), VAS(Visual analogue scale) on recovery patterns after field training(FT) in Korea National bobsleigh and skeleton players. [Methods] The tests were conducted for 3 times at a one-week interval as an experimental design within the same subjects(n=9), observed change ratio in LA, HR, VAS through applying Active recovery(AR), Whole body vibration(WBV) & Cold water immersion(CWI) after FT. [Results] The results were summarized as follows: The alteration of ratio in LA, HR, VAS decreased significantly after applying the three recovery patterns(p<.01). The difference between the groups showed that the reduction in lactic acid according to active recovery and whole-body vibration was higher than cold water immersion(p<.01). [Conclusion] In conclusion, although active recovery was more effective than static recovery, there was a significant effect of the three recovery methods in this study on reducing a fatigue in bobsleigh & skeleton players. Therefore, it would be considered to improve the performance of athletes when these methods apply for them depending on situations and environments.
The importance of a health problem is emphasized in youth. Unfortunately, healthy activity physical education is not well utilized and is not popularly being researched. In order to improve these problems, this study attempted to explore the validity and applicability of SPARK program by designing and practicing the SPARK based P.E. classes. This study employed a mixed method research method based on a qualitative research strategy. Physical activity and physical fitness level were measured by accelerometers and FITNESSGAM. Additionally, empirical data were collected and analyzed by both Photovoice technique and recording. Findings of this study were divided into designing and practicing perspectives. First of all, the PE classes based on SPARK program was designed by 2009 national physical education curriculum and studies associated with the SPARK program. Further, I attempted to specify teaching strategy for enhancing physical activity level, power of execution and motivation. Second, PE class which has higher physical activity level, more participation and achievement, and successful fulfillment were emerged as consequences. Based on the study results, I discussed the validity and applicability of Physical Fitness based SPARK program and proposed suggestions for future studies.
PURPOSE This study analyzed the relationship between the center of pressure (CoP) trajectory area and ankle inversion/eversion movement across different walking speeds and established a new assessment method for predicting ankle instability. METHODS Twenty-seven healthy young adult males (20 yrs) performed treadmill walking trials at three speeds (slow, normal, and fast). Their cumulative CoP trajectory area and ankle inversion/eversion angles were analyzed, with particular focus on the third quadrant area (3QA). RESULTS During slow walking, mediolateral CoP range (p < .05) and 3QA (p < .05) increased significantly compared to normal and fast walking. Concurrently, ankle inversion/eversion angle (p < .05) and range of motion (p < .05) also increased. Furthermore, 3QA exhibited significant negative correlations with maximum ankle eversion angle (p = .001) and eversion angular velocity (p = .005). CONCLUSIONS This study provides findings that the CoP trajectory’s cumulative area, specifically 3QA, serves as a critical predictor of ankle joint eversion kinematics. These findings have potential implications for ankle instability assessment, prevention, footwear design, and rehabilitation protocols.
PURPOSE This study seeks to explore the subjectivity regarding leisure constraints perceived by college student-athletes. METHODS Based on Q methodology as an analysis framework, 25 Q-samples and 25 P-samples suitable for the research purpose were selected, and Q-classification and Q-factor analysis were conducted. RESULTS The leisure constraints were categorized into “Type Ⅰ: Psychological constraints,” “Type Ⅱ: Financial constraints,” and “Type Ⅲ: Spatio-temporal constraints.” The three types provided discussions on “strong athlete identity of student-athletes,” “role conflict between students and athletes,” “core competencies of student-athletes,” “current student-athlete support project,” and “school sports camp training.” CONCLUSIONS College student-athletes’ leisure constraints are closely related to strong athlete identity, anxiety about enjoying leisure, cost burden, and closedness of camp training, and each type provided new perspectives on discussions related to Korean student-athletes.
PURPOSE This study aimed to apply a capacity building program to sport life skill leaders and to provide cases of this process. METHODS The study participants included four leaders (male=2, female= 2, Mage=37.5) who were managing a sport life skills program at a university. They participated in a capacity building program, which consisted of (a) understanding (leader seminar), (b) application (managing the sport life skills program), and (c) evaluation (leader’s self-reflection), which were conducted in eight sessions. Four leaders conducted self-evaluations using program quality assessment (PQA) during every session, and quantitative and qualitative data were collected. Qualitative data were derived using a cross-case analysis, and quantitative data were used for calculating the effect size after performing the paired t-test. RESULTS Analyzing the reported cases of sport life skill leaders, the use value of the capacity building program was identified. Furthermore, the cases reported by the four leaders enabled observation of how the leader’s capabilities were strengthened. In the paired t-test, the effect size of physical and psychological safety, appropriate structure, supportive relationship, opportunities to belong, support for efficacy mattering, opportunities for life skill building, excluding integration of family, school, and community effort, were all significant. All effect sizes were found to have “very large effects.” CONCLUSIONS The capacity building program played a positive role in strengthening the leaders’ life skill coaching capabilities. These findings have practical implications—chiefly, it is important to strengthen leaders’ or coaches’ capabilities in order to foster life skill development and transfer of student-athletes.
PURPOSE The purpose of this study was to apply a life skills program to student-athletes and statistically verify the changes in life skills of the experimental and control group. METHODS Participants were 34 high school Taekwondo athletes (Mage=17.71). They were divided into 18 in the experimental group and 16 in the control group. For eight weeks, the experimental group participated in the life skills program after training and the control group participated in only training as usual. Data were collected by using Life Skills Scale for Student-Athletes (LSSSA), and the participants of two groups filled out the LSSSA before and after the program application. The collected data were analyzed by using repeated measure analysis of variance (ANOVA), and partial η2 (eta squared) was calculated to present the effect size. RESULTS The interaction between time and group was statistically significant in goal setting, coping with stress, positive thinking, and managing emotion among sub-factors of life skills. Partial η2 was interpreted as having a large effect size as it revealed the range of .22 to .51. Therefore, comparing before and after participating in the program, the life skills score of the experimental group among the two groups was significantly improved. CONCLUSIONS Student-athletes who participated in the program experienced positive changes in life skills than those who did not participate in the program.
Purpose The purpose of this study was to investigate how the educational zeal of mothers with winter sports students in secondary schools appears on the network charts. Methods It lasted 28 days from February 6 to March 5, 2017. Starting with a description of the QNA, all interviews were recorded on a tape recorder to carry out the project. Data analysis were divided into four areas(Family, Friend, School, etc.) and 13 associative words(enthusiasm, intelligence, performance, entry, success, sacrifice, atmosphere, polarity, competition, vicarious, satisfaction, economic power, anxiety, stress) to attach associative word stickers according to color. Results As a result of inducing arbitrary interpretation of the network subject's educational network, it was possible to analyze the factors affecting mothers' sports education in three dimensions. In addition, although there is not much difference in areas around "I" on sports education charts, the distance between associative words and network charts has gradually moved away from the same person as their children go on to school. Conclusions The methodological significance of this study has been found to be very useful in visualizing an individual's educational network by utilizing qualitative network analysis and in understanding the characteristics associated with education.
[Purpose] The purpose of this study was to examine acceptance intentions of Sports O2O Service Potential consumers using the revised model of goal-directed behavior. [Methods] The 330 surveys were distributed to potential consumers through convenience sampling method for pilot study. Due to the reliability of data, 42 samples were discarded and 288 samples were put to actual analysis.

The purpose of this study was to describe psychological changes and variables of injured elite athletes during sport injury rehabilitation. 5 injured elite athletes were selected as participants, and open-ended questionnaires, participant observation, and in-depth interview were used for collecting data. Results from the data were analyzed through transcription, coding, and categorization with inductive method. To validate the results of this study, triangulation, in-depth description, member checks, and peer debriefing were used, and findings of this study were as follow. The participants showed negative psychological state such as fear of return to play and anxiety during the initial rehabilitation program, but their psychological state was changed positively such as recovery of confidence and desire of return to play at the end of program. However, the specific psychological changes of each participant showed several differences according to participant's surrounding environment and situation during the rehabilitation program. All findings have important implications for implementing and developing rehabilitation program, so needs to be investigated further.
The purpose of this study was to examine the effect on Electro-chemical screen and anaerobic exercise capacity caused by short-term weight loss in amateur boxing players. Subjects of this study were 10 male university boxing player who conducted to weight loss methods. In 1st weight loss, boxing players took rapid weight loss during 5-7days, In 2nd weight loss, boxing players took weight loss 3kg during 2 weeks. The change of ECS and anaerobic exercise capacity were measured before and after weight loss period. Anaerobic exercise capacity was measured by 1RM of bench press and squat. In addition, using the wing-gate test muscle power and power endurance was evaluated. To find out the changes in ECS, urine and saliva was collected after waking up were analyzed. The results were as follow. First, 1RM of squat(p=.003), peak power(p=.023) and mean power(p=.015) showed significant decrease after 1st weight loss method. However in 2nd weight loss method, no factor of ECS and anaerobic exercise capacity were significantly decreased. Second, total urea(p=.015), urine rH2(p=.017), urine conductivity(p=.003), and utilization of vitamin(p=.005) showed significant decrease after 1st weight loss method. However in 2nd weight loss method, urine conductivity(p=.038) and saliva rH2(p=.028) showed significant increase after weight loss. In conclusion, amateur boxing players need a systematic weight loss to maintain optimal conditioning.
