This research begins from the awareness that even though there are different forms of wrestlings in the ethnic minority groups in China, the study on their morphological aspects has reached the limit. Based on the documents and VOD data about these wrestlings of each ethnic group, their morphological characteristics can be verified as follows. First, The postures of Han and Mongolian people take the way of two players standing and playing, and Korean-Chinese people and Hui people take a saddle stance using a thigh band. Second, as for the arenas for the wrestlings, owing to some geographical features and natural environments, they were set up at a specific area during the traditional era using natural objects(grass, lawn, soil, sand). Yet, in the modern times, they have been changed as being installed and run in modernized gyms, sports fields, or parts following the standard of stadium facilities supervised by each organization. Third, with regard to the play wear of wrestling, some parts of the traditional costumes have been transmitted and worn. However, in case of most of the traditional costumes, it has been found out that modernized clothes which take the forms of garments developed since the modern era into consideration are being used. Fourth, in terms of the game equipments of wrestling, certain clothes(uniform, vest), running shoes and a band(a thigh band) should be worn.
The purpose of this study is to investigate the further direction of molecular biological studies, the advantages and limitations of assaying samples, and variables in figuring out the details of domestic and overseas studies verified through cell and molecular biological analysis in order to analyze the effect of concurrent training. The analysis study was limited to domestic and overseas literature, which investigated the effect of combined training using molecular biological analysis among studies to date. The study was reclassified by specialty, composed of professors of physical education and doctors of exercise physiology. The final selected study analyzed the subject and the trend of studies in terms of comprehensive perspectives. In detail, it analyzed hormonal and enzymatic changes in criteria such as leptin, 5-HT, ACTH(adrenocorticotropic hormone), cortisol, testosterone, GH(growth hormone), LDH(lactate dehydrogenase), CPK(creatine phosphokinase), antioxidants in blood samples and protein, and enzymatic and morphologic changes in for CRP, VEGF(vascular endothelial growth factor), PAI-1(plasminogen activator inhibitor-1), MAD(malondialdehyde), carnosin, and SDH(succinate dehydrogenase), the area of muscle fibers, ratio of type Ⅰ/Ⅱ muscle fiber and capillary proportion per muscle fiber in the extracted muscle by biopsy, for example. Finally, urine samples, and hormonal changes (like cortisol), were analyzed. The results of the analysis of domestic and overseas studies according to combined training has shown that this training has more varied effects than single training and lower improvement by interference effect or magnifying the effect of one type of training amongst the combined training types appears, rather than higher improvement through combined trainings. Therefore, it should be investigated in view of performance improvements relating to the characteristic of sports.
Purpose Sperm quality and function are reduced by environmental factors (e.g., obesity), leading to increased infertility worldwide. Therefore, the purpose of this review paper was to investigate the effects of obesity and exercise training on sperm quality and function in animal and human models. Methods In order to determine the effects of obesity and exercise on sperm quality, motility, morphology, testosterone, oxidative stress, inflammation, we reviewed previous literatures with MEDLINE, PubMed, and Scopus databases. Results The most important factor to control the sperm motility is calcium ion, which is performed by the protein of CatSper (Cation Channel of Sperm). Obese men showed the decrease of number, concentration, motility, and volume in sperm, resulting in delayed or failed fertility. However, regular exercise training increased sperm-mediated factors including number, motility, and morphology, and festicular function-mediated factors including sperm concentration and serum testosterone. Conclusions While obesity exacerbates sperm quality and function in men, regular exercise training with moderate intensity increases sperm number and motility and reduces oxidative stress and inflammation, leading to the improvement of men’s fertility.
The purpose of this study was to identify the structure of knowledge in Sport Pedagogy field. Using bibliometric and social network analysis this study analyzed the keywords and citations appeared in Korean Journal of Sport Pedagogy and Korean Journal of Sport Science during 2006-2015 period. Total of 341 research papers which include 1301 keywords and 14826 citation were analyzed utilizing social network analysis as well as keywords frequency analysis, keyword co-occurrence, citation and co-ictation analysis. Results of this study showed that teaching, curriculum, and teacher education were three central theme in Sport pedagogy field. Key words such as physical activity, PE teacher, action research, and after school sport club activity were prominent research interests for scholard in the field. Quadradic Assignment Procedure analysis showed major research interests has not been changed between two periods of 2006-2010 and 2011-2015. Choi(2010)'s and You(2007)' books were most cited individual work and have influenced sport pedagogy researchers over the five years.
PURPOSE The purpose of this study is to explore the effects of the student-athlete and student peer mentoring program as a collegiate class. METHODS The peer mentoring program, conducted at A University in the first semester of the 2023 school year, was evaluated using practical action research (Zuber-Skeritt, 1996). RESULTS In the introduction stage, ‘relative and absolute evaluation’, ‘member ratio’, and ‘definition of professor role’ were categorized as challenge issues. In the progress stage, ‘de-formalized lecture method’, ‘student athlete’s coaching experience’, and ‘student’s experience of football culture’ were discovered as possibilities, while ‘vacancy and absence of mentor-mentee’, ‘limited group activities and limitations of team sports’, and ‘lack of objective evaluation’ required improvement. At the end stage, student-athletes experienced changes in values such as self-identity, football, and human relationships, as well as quantitative and qualitative changes in sports participation. CONCLUSIONS This study confirmed the potential of the peer mentoring program as a collegiate class as well as its practical significance for guaranteeing student-athletes' learning rights and for forming sports culture on collegiate campuses.
