[Methods] The research analyzed a total of 8 matches played in preparation for the 2023 Asian Junior World Cup, with 19 junior female field hockey players participating. The variables studied were total distance covered (TD, unit: m), low-intensity distance covered (LID, 0-10.9km/h), moderate-(MID, 11-15.9km/h) and high-intensity distance covered (HID, 16km/h), sprint distance (20km/h)and efforts (unit: bouts), and acceleration and deceleration efforts (unit: bouts). One-way analysis of variance was used to validate statistically significant differences in movement by position and exercise intensity. [Results] The study found that, in terms of LID, defenders moved the most compared to forwards and midfielders. However, no significant differences in position were noted for MID, HID, sprint distances, sprint efforts, acceleration and deceleration efforts.

A total of 34 middle-aged women in the exercise group (n=17) and the control group (n=17) were exercised three times a week for 12 weeks at an exercise self-awareness of 11-13 (50-70% spare heart rate) for 50 minutes. After calculating the average and standard deviation for the measurement variables, an independent t-test was used to test the physical characteristics of the pre-exercise group and the control group and the difference in the pre and post average values within the group.BR After the Pilates program, the following conclusions were obtained as a result of comparing and analyzing body composition, growth hormone, insulin-like growth factor-1, calcitonin, and osteocalcin. During body composition, body fat rate and skeletal muscle mass had an interactive effect, and growth hormones, insulin-like growth factors-1, and austeo-calcin also had an interactive effect.BR Taking the above results together, it was found that participation in pilates for 12 weeks had a positive effect on body composition, growth hormone, insulin-like growth factor-1, and osteocalcin. Pilates is thought to be an effective exercise that can strengthen muscle strength and reduce body fat, increase mental and physical balance to maintain a healthy body, thereby stimulating hormone secretion to improve the health of middle-aged menopause women.","PeriodicalId":497986,"journal":{"name":"The Korean Society of Sports Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135979992","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 this study is to find out the perception, sports value and development constraints of college students and field-oriented experts who are participating in physical activities of action cheerleading, to seek the direction of development. For the purpose of the study, a qualitative study was conducted, and the subjects of the study were 10 student members and 10 field-oriented leaders with a lot of professional knowledge and activity experience among Korean university cheerleaders. As for the regions, nine regions were selected and proceeded: Gangwon, Seoul, Incheon, Gyeonggi, Busan, Gyeongbuk, Jeonbuk, Chungbuk, and Chungnam. As for the sampling method, a semi-structured in-depth interview was conducted using purposeful sampling, which is a nonprobability sampling method. The semi-structured questions were modified and supplemented through a pilot test. The harmonized questions were revised and supplemented through a pilot test. The interview contents were transcribed and triangulated, and the results were derived by reading them several times and classifying common contents.BR The results of the study are as follows: First, the common perceptions of university students and experts were ‘enjoyable’, ‘exciting’, and ‘physical health’.

The subjects of the study were high school baseball pitchers(n=10) and evaluated using the Baseball Athletic Test(BAT). BAT was a field test for baseball pitchers and analyzed body composition, flexibility, muscular strength, leg power, agility, running speed, and throwing velocity, and the following results were derived. First, body composition(height, weight, body fat percentage, muscle mass) did not show a significant correlation with throwing velocity. Second, grip strength showed a significant correlation with pitching speed improvement(R²=.683, p＜.05) Third, vertical jump showed a significant correlation with throwing velocity(R²=.754, p＜.05). Fourth, 60yd sprint was found to have a statistically significant correlation with throwing velocity((R²=-.766, p＜.01). To summarize the above, baseball pitchers showed significant correlations with vertical jump, grip strength, and 60yd sprint. Therefore, leg power, grip strength, and running speed among professional physical fitness factors are judged to be important factors in improving pitcher’s throwing velocity, and are judged to be effective basic data for analyzing and training pitchers’ physical strength in the future.","PeriodicalId":497986,"journal":{"name":"The Korean Society of Sports Science","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135778157","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}
