For the structure of the qualification framework integration, integrating it into the two-level or three- level system has the greater advantage in various aspects and it may minimize controversy.CONCLUSIONS The qualification framework should be integrated into the two-level or three-level system, and the selection of the written examination subjects should be revised. To consider the sequence of the courses and learning contents for the National Physical Education Leader qualifications, the following written examination subjects should be included as the compulsory subjects for the three-level, twolevel, or one-level systems respectively: exercise physiology, exercise mechanics, sports psychology, and health education; physical education measurement and evaluation, health and fitness evaluation, exercise prescription, and pathophysiology; and prevention and treatment of sports injuries and training theory. One of the innovative strategies to improve the current exam contents, the following written examination subjects should be eliminated such as sports education, sports ethics, Korean sports history, and sports sociology or significantly reduce the number of questions to be asked. Another strategy is to determine the eligibility qualifications according to standard guidelines on the knowledge, skills, and attitudes required for each job area by subject and position according to the qualification system, such as the secondary education teachers exam or the certified nutritionist certification exam, and select exam contents and numbers of the question in each subject according to the essential knowledge and skills. It is also worth considering the question of different ratios.","PeriodicalId":22264,"journal":{"name":"The Asian Journal of Kinesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88367543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of current study was to exam the effects of BJJ on body composition, health fitness components, and functional movement screening (FMS) in healthy young adults.METHODS Combined exercise program was composed of aerobic and resistance exercises. All participants were randomly assigned either into BJJ exercise group (BJEG, n=10, 28.10±2.64 years) or combined exercise group (CEG, n=10, 28.20±3.43 years). Exercise intervention was conducted for ninety minutes per session, three times per week for twelve weeks.RESULTS Body fat (%) and muscle mass (kg) were significantly improved in both groups. Muscle strength in upper and lower extremity, muscle endurance, flexibility, power were significantly improved in both groups. Cardiorespiratory fitness in BJEG was significantly improved. Also, FMS total score and deep squat score showed significant improvement in both groups.CONCLUSIONS BJJ is an effective exercise for health and fitness management purpose in non-elite healthy young adults.","PeriodicalId":22264,"journal":{"name":"The Asian Journal of Kinesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90064561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The brainwave activity was measured by measuring and analyzing brainwaves at eight regions at the prefrontal lobe, the frontal lobe, the temporal lobe, and the occipital lobe using brainwave measuring equipment. Brainwaves were measured for 5 minutes in a sitting position in a stable state and were also measured for 5 minutes after 15 minutes of the chudan-no-kamae movement, which is aiming at the opponent with the point of the sword while moving along eight moving lines of the opponents, and for 5 minutes after 15 minutes of three striking movements.RESULTS Alpha waves showed higher brainwave activity during the stable state than during the kendo movements (three striking movements, chudan-no-kamae) while SMR, M-beta, and H-beta showed higher brainwave activity after kendo movements than during the resting state. The asymmetry between the left and right sides increased after the movements compared to during the resting state.CONCLUSIONS These results are considered attributable to kendo training that partly increased their concentration thereby increasing brainwave activity. However, it is unclear that kendo training will be helpful for concentration through physical activities and brain activity in this study. Therefore, further study should be conducted with the measurement of factors related to emotional aspects, concentration, and brainwaves according to kendo training.","PeriodicalId":22264,"journal":{"name":"The Asian Journal of Kinesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77264502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS Forty-seven healthy female college students (17.2 ± 0.4 years) were included in the study. The CBDs were calculated by themselves using a graphing calculator as their learning activity. CBDs were based on four jump distances and approach-run distances (including self-selected distance [SSD]). RESULTS There was no significant difference between maximal SSD (JDSSD) and maximal CBD (JDCBD). There was no significant difference between SSD and CBD. Moreover, on average, there was no significant difference between JDSSD and JDCBD. From the viewpoint of individual differences of delta in JDCBD−JDSSD, the association with the speed-effectiveness index (SEI), as one of the jump skill metric, was investigated. The correlation coefficient between SEI and delta in JDCBD−JDSSD was not significant.
