Oh, Tae-Woong(오태웅) 한국체육과학회 2020 한국체육과학회지 Vol.29 No.1

The height of the vertical jump is a common indicator that allows for the evaluation of the net thrust of the lower extremities. Additionally, the foot movements during count movement jump(CMJ) and repletion jump(RJ) are mechanically different. Therefore, this study aims to provide basic data related to differences in the jump performances for CMJ or RJ depending on sport events. The study participants included 47 men and 33 women. Men’s events were handball(n=24), softball(n=11), and track(n=12), and women’s events were volleyball(n=20), track(n=7), and fencing(n=6). In this study, two types of jump motions were measured: CMJ or RJ. For all jumps, the hands were positioned near the back to prevent arm-waving motions. Ball players need to run, throw, jump, etc., during the game. Sometimes these movements require explosive exertions of great force, and sometimes they require rapid speed. As such, many abilities are needed in ball sports in general. It is also believed that sex differences in the study were characterized as above. These results were thought to reflect, in a sense, the characteristics of ball games. In this study, there were no significant differences in jump performances between the races.

The purpose of this study was to examine the effects of a 16 weeks diet management program on body composition and BMI in adult women. The management will conduct exercise management for 510 people who participated in the diet program for 16 weeks from September 6, 2015 to January 6, 2016 twice a week for one week and 60 minutes for one week. The results were as follows. First, there was a significant difference between the normal weight group and the high obesity group except the low - weight group. Second, in the variation of BMI, the weight loss decreased more effectively and stably as the BMI was higher. Especially, decrease of body fat and BMI was significant. Therefore, this dietary management program has been shown to be effective on dieting by significantly reducing the body fat rate for each 16 weeks, and it is thought that the decrease of the abdominal fat rate positively influences the prevention of the metabolic syndrome.

This study has the objective of analyzing the difference between age of children and fundamental motor skill achievement rate and finding out developmental tendency. Study targets were 393 children registered at child education organization located in city G and I in province K (149 at age of 3, 133 at age of 4 ad 111 at age of 5), and fundamental motor skills (movement exercise skill – stepping backward, running on one foot, running with raising knees, running while pushing, standing long jump, stable motion skill – standing on one foot, rotation, spinning like top, avoiding ball, rolling forward, manipulative movement skill – out-throwing ball, throwing ball precisely, bouncing ball, catching ball, kicking ball) achievement rates were measured. The results of this study are as follows. It showed that the children’s fundamental motor skill achievement rate had differences according to the age increase. When you present the age and fundamental motor skill achievement rate of children for each lower level zone, it showed the differences as follows: movement exercise skill achievement rates were 71.8% for age of 3, 85.3% for age of 4 and 95.7% for age of 5, stable motion skill achievement rates were 75.0% for age of 3, 86.4% for age of 4 and 94.1% for age of 5 and manipulative movement skill achievement rates were 33.6% for age of 3, 54.0% for age of 4 and 71.2% for age of 5. When you summarize these, fundamental motor skill achievement rate of children had differences according to the age, movement exercise skill achievement rate and stable motion skill achievement rate were found to be developed showing uniform rate achievement rate according to age increase, and manipulative movement skill achievement rate seems to have the tendency of gradually developing along the age increase slower than movement exercise skill and stable motion skill.

This study analyzed the correlation between hip joint position and back pain through Functional movement screen (FMS) and manual muscle test (MMT), Special Test (SPT). Participants of both genders (30 males) were solicited from three combat sports (karate, Wushu and Taekwondo). All correlations produced were p<.05 level of significance. The results for pain awareness through the questionnaire was 3.97±1.54, measured to be ’lightly painful’. The results of the analysis of pain perception and correlation with the FMS of the entire speculative athletes show the pain awareness level in the deep squat (r= -.503, p<.005). with significant correlation, Active Straight leg raise (ASLR) also showed significant correlation with (r= -.689. p<.001). The pain perception and correlation analysis results with Special Test (SPT) and MMT show that significant correlation with pain perception in Straight leg raise (SLR) test (r= .675, p<.001). The results for the correlation analysis of FMS, SPT and MMT first showed significant correlation with the patrick test (r=.399, p<.05), and the Huddle step showed significant correlation with SLR test (r=.580, p<.001).The combined results of this study confirmed the results of the FMS, SPT and MMT, which differ slightly depending on the event, but do not show any significant differences. In addition, a significant correlation between SPT, MMT score and pain awareness was confirmed through the examination of pain awareness, and a number of significant correlation between FMS, SPT and MMT was established. These findings can be used as basic data that can be used to prevent injury and predict back pain of a competitor through FMS at a sports site.

[목적] 이 연구의 목적은 COVID-19 대유행 전후의 엘리트 성인 선수들의 활동과 식습관을 조사하여 엘리트 청소년 선수들에게 COVID-19가 미치는 영향을 파악하는 것이었다.[방법] 총 917명의 엘리트 청소년 선수들을 대상으로 실시되었으며, 19개의 스포츠와 6개의 그룹으로 분류하였다. 설문지는 COVID-19 이전과 이후의 신체 활동, 수면 및 식습관에 대한 인구통계학적 요인 및 신체활동, 식습관에 관한 문항이 포함되어 총 44개 설문문항으로 구성되었다. 모든 자료의 통계적 유의수준p <0.05로 설정하였다.[결과] COVID-19 이후 모든 종목에서 고강도 및 중간 강도의 활동이 감소했다. 그러나 저강도 활동은 거의 모든 종목에서 증가했다. 또한 모든 종목에서 앉아 있는 시간이 증가했으며, 식사 횟수는 종목마다 차이를 보였고, 모든 종목에서 경기 횟수는 감소한 것을 확인하였다.[결론] COVID-19는 끝난 듯 보이지만 아직 끝나지 않았다. 선수들은 원래 능력에 근접한 후 신체적, 생리학적 및 심리적 상태를 유지하는 최선의 방법을 찾는 것이 매우 중요하며. 이점은 COVID-19 이후 선수 복귀에 가장 큰 영향을 미칠 것으로 판단된다. PURPOSE This study aimed to investigate the effects of COVID-19 on elite youth athletes by investigating their activities and eating habits before and after the COVID-19 pandemic. METHODS This study included 917 elite adult athletes from 19 sports and were grouped into 6. The questionnaire included items regarding demographics, physical activity, sleep, and eating habits before and after COVID-19. A total of 44 questions requiring subjective short answers were included. Statistical significance was set at p< 0.05. RESULTS After COVID-19, vigorous and moderate activity decreased across all sports; however, light activity increased in almost sports. Time spent sitting increased across all sports. The difference in the number of meals consumed varied among sports, and the number of competitions decreased in all sports. CONCLUSIONS The COVID-19 pandemic appears to be finished but has not ended yet. Athletes must determine the best way to maintain their physical, physiological, and psychological states close to their original abilities. Determining this will provide the greatest impact on the return of athletes after COVID-19; this study will be helpful.

PURPOSE: The purpose of this study was to analyze the differences of bone density and structure after immobilization prior aerobic exercise and resistance exercise. METHODS: Twenty four mice were randomly divided into 3 groups: CC: 4weeks control cage after 2weeks immobolization (n=7), RT: 4weeks resistance training after 2 weeks immobilization (n=7), AE: 4 weeks aerobic training after 2 weeks immobilization (n=7). The prior exercise was performed aerobic and resistance exercise. The body weight, muscle weight, and bone morphometric microstructure parameter including bone mineral density (BMD), bone specific surface (BS/BV), percent bone volume (BV/TV), trabecular thickness (Tb/Th), trabecular number (Tb/N), trabecular separation (Tb/Sp), structure model index (SMI), connectivity density, and cross-sectional area was evaluated using by microcomputed tomography (micro-CT). One-way repeated ANOVA was used to evaluate the differences between three groups and paired t-test analysis was applied to examine the different between immobilization leg and non-immobilization leg. RESULTS: The results of this study indicated that the body weight was increased after 4 weeks, and decreased after 2 weeks immobilization. The gastronemius and soleus muscle weight was significantly decreased in immobilization leg compared to non-immobilization leg. BMD, BV/TV, BS/BV, Tb/Th, Tb/N, Tb/Sp, and Cross-sectional area in immobilization leg of CC was lower than immobilization leg of RT and AE. CONCLUSIONS: These results suggest that 4 weeks prior exercise might improve the bone density and microstructure, even though 2 weeks immobilization. Especially, the prior resistance exercise has more beneficial effects on muscle weight, bone density and microstructure.
